If not all users of Android systems, then many of those who install custom (non-original) firmware know that the appearance of the Installation Aborted error during firmware is a fairly common phenomenon. And this is not connected at all with the data being installed, but with the version itself operating system. Most users start this process without thinking about it at all. possible consequences. And they can be very sad (even if the firmware is not installed, the system may simply crash, and after that you will have to restore factory setting with complete loss of user data and any other related information).
Installation Aborted error when flashing firmware: what is this in general understanding?
Let's start by clarifying the term itself. What does it mean when mobile device When flashing firmware through recovery it says Installation Aborted, which is generally not difficult to understand.
It is enough to simply translate the message from in English into Russian. Receive a notification that the installation has been interrupted. But why does such a failure occur? You can read about this and much more in the material presented below. In addition, the usual cancellation of the installation is the worst thing that can be achieved when carrying out such actions. The fact is that Android systems react quite sensitively to any changes, and can only work with selected devices, for which only a certain version of the operating system can be used. Relatively outdated OSes and devices have practically no support in terms of updating the operating system. Updates affect only built-in services and custom applications, but nothing more. You can only update your operating system to a certain supported level.
Installation Aborted during firmware: what to do?
It is clear that when installing official updates, supported by Android operating systems, failures of this kind do not occur. The only situation when the system writes Installation Aborted when installing the firmware is due to the fact that the user installs the Firmware independently.
In principle, this is some kind of protective function, similar to the appearance blue screen on Windows systems. Only Android behaves much more modestly.
The main problem is not even the installation method, but the fact that this firmware may simply not correspond to the device on which it is installed. And to begin with, when canceling the process, just reboot mobile device and restore the original system. After this, you can proceed to install the new firmware again.
Lock
Sometimes, when installing firmware, Installation Aborted also signals that the original update file was not placed in the area that is perceived by the device as a default reserve.
As a rule, in order to avoid Installation Aborted failure when flashing a smartphone or tablet, the Update.zip file should initially be placed in the root directory of the internal storage (Android). Only after this can additional actions be performed.
Operating system update
Another failure option, when the system writes Installation Aborted when flashing the firmware, can be interpreted as the current version of the operating system not matching the one the user is trying to upgrade to.
This is akin to trying to jump from Windows XP to Windows 10 on desktop computers. First, for the Android OS itself, you need to install an update that is supported by both the system and the device, and only after that start flashing the device.
Many experts also call freeing up space on the internal storage as one of the most basic conditions for the successful completion of the process. Don't look at the fact that there is enough space on it. The most basic problem is that it contains undeleted cache data, which is perceived by the system as real garbage, although it may not signal this.
Thus, one of the options for eliminating Installation Aborted failure during firmware is to initially delete this type of data. You can use standard settings, from where you go to the applications section, select “All” and then clear the cache of each applet presented in the list.
It is much better (and this makes the task easier) if the user has an optimizer application installed on his phone or tablet. Such applets, in general, behave quite correctly. True, cleaning issues sometimes raise legitimate doubts, since the user sees one thing on the application screen, but in fact nothing really happens. Don't believe me? Look anywhere file manager to the DCIM and 100ANDRO directories, which are located directly on the internal drive where the operating system itself is installed.
CMW Installation Issues
Another point related to the possibility of eliminating the problem of the Installation Aborted error appearing during firmware relates to the installation of the CMW module, which is extremely necessary for such operations. Its installation will allow you to avoid problems associated with incompatibility of ROM drives. But to use it, you initially need to obtain so-called root rights.
In the very simple version can be used Kingo program Root, which is initially installed on a personal computer or laptop. After connecting the mobile device, the rooting driver will be downloaded, and then the mobile applet will be installed on the mobile device (a confirmation will be given on the computer directly in the program). After this, it will be enough to simply launch the corresponding mobile applet to perform further actions.
They consist of installing Rom Manager, and in Recovery mode, using the Setup section, go to the ClockworkMod Recovery menu, find your mobile device model in the list provided and agree to carry out further operations.
Restoring factory firmware
Sometimes this approach does not work, since sometimes the presented solutions can only be used on original firmware. Resetting the settings on your phone or tablet won't really do anything.
Therefore, it is advisable to immediately install the program that best suits your device (Xperia Companion, Samsung Kies, etc.), and restore the factory firmware via the Internet using it. And only after that you can start installing new firmware, if necessary.
Instead of a total
This is the solution to the Installation Aborted error when flashing firmware. What to do, I think, is already clear. In general, by and large, it is worth saying that flashing a mobile device using unsupported versions of Firmware is not recommended at all. So you can, as they say, simply ruin the device. You can install the firmware only if it is actually taken from an official source and is fully compatible with the model of the device that is supposed to be flashed. Otherwise, don’t even try to perform any such actions.
Updating or installing firmware can eliminate many problems related to the functioning of an Android device. During long-term use, system memory mobile gadgets clogged with residual files () (“casts” of previously downloaded programs), malicious code() and other unnecessary data. All this leads to a decrease in the performance and speed of the processor and RAM. As a result, the smartphone (tablet) often begins to freeze and reboot on its own. And if factory reset() did not result in positive result, the user can only update the software himself. Let's look at how to reflash a phone running on Android OS.
Types of firmware and methods of installing them
Installing Android firmware at home differs in many ways from installing other software. This process is more labor-intensive and associated with many risks. If you select the wrong software version or violate the update process, there is a possibility that your phone or tablet will become useless. However, having learned how much reflashing costs from professionals, many still decide to change the software version themselves.
For flashing Android, there is no single instruction that would fit all models of mobile devices. It all depends on the manufacturer of the device and what software you plan to install.
All Android firmware is divided into two types:
- Official. Supplied directly by smartphone manufacturers and usually only suitable for a specific brand. Such programs are considered the most reliable, so they should be used whenever possible.
- Unofficial (custom). Developed by Android device users and small companies. They are applied when reinstalling Android on Chinese devices(for example, Lenovo, Meizu, Xiaomi, etc.).
When using custom software, there is a possibility of installing a low-quality update, as a result of which the gadget will begin to slow down even more. Therefore, you need to download the executable file only after reading its description in detail and reading user reviews.
There are several ways to change the firmware on Android:
Preparing for self-flashing
Before reinstalling the software on your Android device, you need to make a number of preparatory measures:
- download a software update program to your PC (Odin, Kies or SP Flash Tool and find a high-quality usb cable (if the reinstallation will be done using a computer);
- (if you plan to reinstall Android to an unofficial version);
- charge the gadget's battery to 100%;
The functionality of the installed software largely depends on its version and build. To new firmware after some time it did not start to conflict with the hardware, you need to find out serial number mobile device:
Let's look at a more detailed procedure for updating Android on a phone using Samsung and Lenovo as examples, although these instructions are also suitable for many other brands.
Smartphone firmware from Samsung
Software updates on Samsung devices are carried out using the Kies program. This utility allows you not only to reflash your tablet or phone, but also to make a backup copy of the old system, synchronize personal data with your PC and much more.
Before changing the firmware to the latest software, you need to configure Kies correctly. This is done as follows:
After setting up Kies, create a backup of the software available on your smartphone. This will allow you to restore system functionality in case unsuccessful firmware. To backup Android via PC, in the initial application window, select “ Backup", mark the items you want to save and start the procedure by clicking the corresponding button. 
After creating a backup copy, feel free to reflash your phone or tablet via your computer. To do this, open the “Tools” section in Kies and activate the item marked in the figure, thereby starting the update process. 
While the device is being flashed, do not under any circumstances disconnect it from the PC or perform other actions that could lead to a disconnection.
After flashing your Android phone through a computer, check the functionality of all its functions. If nothing fails, it means the software update was successful.
Replacing firmware on a Lenovo tablet via PC
Before flashing a Lenovo tablet, you need to understand that there is no software developed specifically for this brand. Therefore, we have to be content with universal developments. One such application is SP Flash Tool. Let's look at how to update software on Lenovo using this utility:
After you have succeeded in updating the firmware, check that all functions of the tablet are working.
This post (manual or mini FAQ) is intended for people who have difficulties flashing or updating the software of their electronic device. Everything will be illuminated here typical errors, which prevent you from flashing your phone.
To be honest, in all the time I have been working as an engineer, I have seen quite a few such problems. I won’t be able to remember everything right away, but I’ll show you the bulk of these jambs that prevent you from flashing the device. And therefore this manual will be replenished and grown over time.
You can also write your problems with the firmware in the comments - this is welcome. Before you start flashing firmware, updating software, rooting or other actions that could kill the device, follow the following rules.
1. Attentiveness and “straight hands”
Almost every day I have to fix other people’s bugs that led to the device not working due to the user’s fault - he just wanted to update the firmware on his phone, but never did it and pressed any button in the process, or inattentively read the instructions according to the firmware, or chose the wrong software version - turned your favorite gadget into a “brick” - a useless piece of plastic, glass and metal.
Learn from other people's mistakes. This means, before you press the START or DOWNLOAD button (there are others), find a workable scheme for updating software, firmware, rooting, or installing any other software. Do everything strictly according to the manual and do not change the flasher settings if you do not know what this may lead to. Just be careful.
2. Defective battery
Due to a faulty or discharged battery, the device may not be fully flashed or may not even begin the process itself. Such cases are also not uncommon. The Fly IQ4404 Spark with its clumsy battery immediately comes to mind. I fully charged this battery and put the device on firmware and after a few moments (in different ways) when loading files an error occurs and the process stops. And now we have a “brick”. But this is a fly; it is not afraid of such zigzags of fate; it is enough to start the firmware again.
I start over (the battery is fully charged, according to the phone indicator) and a minute later the error occurs again. Well, I think the “flash drive” has died and I’m starting to get upset, but I don’t give up. I'm going to flash it for the third time, but without this battery, and I'm hooking up the power supply. The device has flashed. You can object to me and say that this is some kind of accident, but this is a fact.
I had more than one or even ten of these. But in fairness, I will say that it is special case and in 99 percent of cases the devices are flashed normally if the battery is charged. There is equipment that can be flashed without a battery at all. But it’s better not to take risks - don’t be too lazy to charge the battery.
3. Software problems
It happens that the device does not want to be flashed due to the software installed on the computer or laptop. Everything here is individual, but the same is true.
For example, there are phone models that are “sewn” only on WINDOWS XP PROFESSIONAL SP3, but on the seven they are no longer detected or the firmware program is stupidly not installed, giving an error. Also, if the necessary components were not installed in the operating system, the drivers were installed normally, but the smartphone was no longer detected in the system.
I had such nonsense because of the stripped-down Windows - WINDOWS XP HOME EDITION. I had to install everything manually, and that was a real hassle. Here are a few more reasons that will lead to errors - broken firmware archives and flashers, incompatible software versions with hardware - it happens that several different revisions are released for a certain phone model motherboards, on which processor and memory chips from different manufacturers are installed, because of this there are several firmwares, not correct installed drivers, lack of administrator rights in the system.
If the firmware is not installed correctly, the boot (boot area) may crash and the device will stop showing signs of life altogether - in 90 percent of cases you will have to contact a service center where there is a special programmer. So be very careful, double-check everything several times.
4. Hardware problems
If your device freezes, turns itself off, does not turn on, or its battery quickly discharges during operation, then it is not a fact that these problems will disappear when updating the software or resetting the settings. Here, most likely, everything is much sadder, and this is precisely what is connected with the hardware of the gadget.
Here are a few typical problems due to which the phone may not be flashed - the system connector is damaged or dirty, the cable for the firmware is damaged or it is not entirely original, the USB or COM connectors of the computer are faulty, there is liquid inside the device, problems with the power supply circuit, etc. This may There can be a huge variety of reasons. In this case, contact the service center for diagnostics.
Be sure to do this before installing the firmware:
1.
Fully charge the battery.
2.
Check visually for damage to the fur, dirt on the PC and phone connectors. If there is one, it needs to be corrected.
3.
Make sure the cable for the firmware is original and in good condition.
4.
Check all downloaded firmware, flashers, drivers, etc. for viruses and integrity.
5.
Also make sure that you have correctly installed the drivers, flash driver and other necessary software components.
6.
Strictly follow the instructions when updating the software.
If you follow these simple rules, you will have much less hassle during the software update process. Write your problems with firmware in the comments. Let's fix them together. Good luck.
Share:The Android operating system is very stable, but in some cases problems may arise with it. They are usually associated with the operation of the current firmware. There are many ways to flash the firmware; In this article we will look at how to flash Android via Recovery.
There are several main ways to enter this mode:
How to get ROOT rights: Video
Firmware with ROOT access
Let's look at how to install firmware through it. First of all, you need to find and download it as an archive new version firmware.
The gadget will reboot and 8 items will appear in front of the user. Each of them is responsible for a specific operation. For example, if you go to “Wipe / Factory reset”, the system will be reset to factory settings (in some cases, simply by activating this item, you can avoid the need to change the firmware when the device begins to work incorrectly). “Install” makes it possible to install files when this cannot be done from the shell itself.
To install the firmware, you need to go to the “Install” section (it is located in the extreme left corner), select the place where the firmware was downloaded, and start the process.
After some time, the system will report a successful completion, then you will need to exit the “Install” mode and select the “Reboot” mode. There, click on the “System” item: if the entire operation was carried out correctly, the device will boot successfully.
Flashing Recovery mode
Now let's look at the question of how to flash Recovery on Android. To do this you will need to install the so-called CWM Recovery. The easiest way to do this is with special utility, which can all be found in the same store Google Play via this link. In this case, you will also need superuser rights. Having launched the program, you just need to follow its instructions by clicking “Next”. If CWM Recovery is already installed on the system, then the utility will simply ask you to select the appropriate item that performs an action related to flashing or resetting to factory settings.
Any device with Android OS starts in Recovery mode. This standard function. However, with the factory version you can perform too narrow a range of tasks. So, this is resetting the phone to initial settings, clearing the cache, as well as updating the system from the update.zip file. Obviously, users who are expanding their knowledge in the IT field are very dissatisfied with such a meager list. This is where specially developed Recovery Mode s. CWM Recovery is a popular tool among Android users and a worthy replacement for the factory one.
Why do you need CWM Recovery mode?
Clockworkmod Recovery(CWM) is a famous alternative to factory recovery mode developed by Koushik Dutta. You can install it on most Android devices. CWM Recovery helps even in situations that sometimes seem hopeless to the average owner. That is why it is necessary to know about its existence, and also be able to use it.
CWM mode has many options
What exactly does the utility do:
- Installs unofficial custom firmware and kernels.
- Installs factory system updates, add-ons and OS patches.
- Connects to a computer via USB in removable storage and for working with the ADB program.
- Creates a complete backup copy of the current firmware and its individual parts (system, settings, applications).
- Restores the device from a previously created backup.
- Resets settings to factory settings (Wipe - data/factory reset), clears cache (wipe cache), clears Dalvik-cache (wipe Dalvik-cache), clears battery statistics (wipe battery stats).
- Creates partitions on a memory card and formats them.
CWM: installation instructions
ClockworkMod is sewn into the internal memory of the device in place of the factory mode. In some cases, work is carried out on the gadget itself with access to Root rights, and in others - on a PC.
The article covers such basic methods as Rom Manager, FastBoot, Rashr and Odin. For many devices, companies themselves produce separate utilities, for example, Acer Recovery Installer for Acer devices. CWM is implemented into the device memory on these devices also through ADB software, which is suitable for devices manufactured by HTC.
Rom Manager: Rooting and embedding
Rom Manager is a utility created by the CWM developers. It is available for download on Google Play Market. Allows you to install CWM Recovery on the device itself without using a computer and a USB cable. Before using it, you must root the device, that is, obtain administrator rights.
Obtaining Root rights
The procedure is simple and can be easily carried out using special software. As an example, we can take the Framaroot program. Anyone can navigate its simple and intuitive interface, even without instructions.
Launching Rom Manager
Now is the time to use the program:
Video: how to flash Recovery with Rom Manager
Although the method is easy, it has a drawback: it is not suitable for all devices, as mentioned earlier. Before you start using this method, it would be logical to first determine that this program is compatible with the gadget. The list is available on the official Rom Manager website.
FastBoot Mode: Complex Method
The CWM installation method using FastBoot will require skill from the user, as it is much more complex than the previous one. It runs not on the device, but on the computer. It is recommended to use it only if you already have skills in such operations. Before installation, you must download it to your computer or laptop. certain files. This list also includes the platform Android SDK, available for Windows, Mac and Linux.
Preparatory stage
What you need to have before installing CWM using FastBoot mode:
- A computer with Windows OS and a USB cable to connect the device to the PC.
- USB drivers for correct device detection. They can be downloaded from the official website of the manufacturer.
- Android SDK platform.
- Recovery file.
The Android SDK utility will help you install the necessary Android SDK Tools and Android SDK Platform tools packages:
What else needs to be done before starting the firmware itself? Judging by the list above, you need the recovery-clockwork.img file. This is one of the key tools for further work. Downloading it won't be difficult, but it doesn't end there. It is important to place this file in the platform-tools folder. For further convenience in the firmware, you need to rename it to recovery.img.
Place the file in the platform-tools folder
Get straight to the point!
Now everything is ready for the CWM firmware itself, so you can safely get to work. Given below detailed description action in which it is quite difficult to get lost.
The level of complexity, as you can see, is high, so before the procedure it is strongly recommended to check that this method is suitable for the device, since it may not work in all gadgets. In practice, this method is good if the manufacturer of the device is HTC.
Rashr app
The installation method using Rashr is convenient and easy to perform; it is recommended for beginners. However, ironically, it also requires administrator rights. You can get them in a few steps. was given earlier in the section on Rom Manager.
How to work with Rashr
First you need to download the application itself. It is located in free access V Play Market(Rashr - Flash Tool). You can also view the program on a third-party site, but you must beware of suspicious web pages so as not to catch a virus.
When the program is already on the phone, you need to open it and provide it with previously acquired Root rights upon request. Then everything is simple:
Video: CWM and Rashr
Odin: solution for Samsung
The previous three methods are suitable for different models devices. The same method is effective for Samsung devices. This is a proprietary utility, so it cannot be used for devices from other manufacturers. There are many versions of this application. The latest one is Odin 3.09.
Here is the standard factory one Recovery option changes to a modified one using a PC, as with FastBoot:
How to enable CWM Recovery mode after flashing
Once CWM mode has been installed using one of the above methods, you need to check if it works. You can launch ClockworkMod Recovery:
- using the ROM Manager program by selecting home page"Download" section Recovery mode »;
- by pressing the keys simultaneously after turning off the device. Combinations may vary depending on the model and manufacturer of the device. In most cases, these are the volume down and power buttons;
- by using ADB programs via the adb reboot recovery button.
Possible difficulties
During the installation of an alternative Recovery Mode, in particular CWM, various difficulties and errors may arise. Which of them are the most common and how to solve them?
CWM Recovery does not recognize the memory card
CWM makes it possible to update your phone using an archive. When opening Recovery, the user sees a message that the flash card cannot be mounted. After installing another card, even with less memory, the problem disappears. The reason lies in the Windows system. The fact is that it diverges from card formatting standards. To ensure that formatting is done according to the specification of SD/SDHC/SDXC flash cards, and not just to standard form, it is recommended to use specialized software, for example, SD Formatter.
The SD Formatter program allows you to correctly format the SD card
CWM does not see the internal memory of the device: problem solution
When the files to be recovered are on internal memory, and therefore can only be restored from there, a problem may arise. When connected USB cable to the PC and enable “USB Debugging”, the program reports that Android device not detected and you need to enable “USB Debugging”.
To solve this problem:
- Connect the device as a camera, not a storage device. If there are other options available, choose them.
- Install universal drivers.
- Find a more suitable one Recovery program for the device.
Recovery menu doesn't work
If when you launch the alternative recovery mode (volume + Home button or power) a picture appears with a lying robot, then the recovery was flashed, but when you restarted the device it was overwritten by the stock Recovery.
The problem is solved as follows.
- Before flashing the Odin3 program, you need to uncheck the Auto restart checkbox and disconnect the cable after flashing. From Download mode on the device, go to recovery mode by pressing the volume up + home screen + power keys in sequence and hold them until the recovery menu appears. So you should get into the custom recovery menu anyway.
- In it, select Reboot system now and then check Yes. This action will overwrite the stock recovery with a custom one and the “No command” error will be corrected.
Flashing a new Recovery mode means getting new functionality. Firmware methods vary in complexity, but ironically, the simplest of them require access to Root, that is, device administrator rights. When choosing a firmware method, you need to be guided by the phone model first. Rom Manager is not suitable for all devices. For HTC, the FastBoot method is more suitable, while for Samsung it would be more correct to choose Odin.
What to do if your smartphone is based on operating system Android suddenly started freezing and acting as if it had a life of its own? How to reflash a device based on the operating system Android systems ?
Many users of modern gadgets of well-known brands are tormented by this issue: starting from top Samsung devices or Sony, ending with the increasingly popular “Xiaomi” and “Meiza”.
Possible solutions to problems
“Recovery”: what is it and what is it eaten with?
Many users immediately give up and rush to contact service centers. However, any experienced user knows that this is not necessary. After all, you can save a decent amount of money and nerves by following just a few simple steps given in this manual. "Recovery" is a special software that is available in smartphones based on the operating system. Android systems. It is something like the BIOS on a regular personal computer. That is, with the help of “Recovery” you can carry out full reset smartphone to factory settings. Here you can also flash the device's firmware or install operating system updates. Upon purchase, the user most often receives a device with the factory “Recovery” menu. It is slightly limited in functionality and does not allow you to successfully flash the operating system. If we talk about “custom” “Recovery”, then it allows you to more fully interact with the phone system. Thus, you can make backup copies of firmware and restore them, as well as perform a deeper and more complete reset of the device.
"Recovery": how to enter
To flash the device through the “Recovery” menu, you need to get into this very menu. This can be done quite simply, especially since many devices use the same input combination. So, if your smartphone has a “Home” button or a physical central button, then with the gadget turned on, you need to simultaneously press the “Volume +” and “Home” buttons. After that, without releasing these buttons, you need to press the power button. The device should turn on desired mode. In the event that the user has more modern apparatus without a physical Home button, you will need to repeat the process described above, but only when using the Volume+ and Power buttons. If the desired result is not achieved, it is recommended to refer to the extended list of methods for entering the “Recovery” menu for devices from various manufacturers.
What else is needed?
To understand how you can reflash an Android-based device, you must first download the firmware for your device. Firmware files are most often hidden from public view in order to protect the manufacturer’s data and security. It is for this reason that ordinary users create backup copies of their OS and form them into databases of stock firmware, links to which can be found on special sites. It is the firmware file itself, which is located in the archive with the *.zip extension, that will be needed in order to learn about restoring “Android” through “Recovery”. Sometimes there are times when old firmware users get bored and want something new. It is for this reason that there are always craftsmen who develop custom firmware, adding something new from them or, on the contrary, “cutting out” unnecessary things. In this case, you won’t be able to use standard Recovery. This is where custom CWM Recovery or TWRP comes to the rescue.
How to install CWM Recovery or TWRP
It is not necessary to install Recovery on Android using personal computer. Most often it is easier to use stock. All you need to do is download required file, which is located in an archive with a *zip extension and move it to an external flash card of your smartphone. After that, you need to go to the stock “Recovery” and select the “Apply update external storage” item there. In the list that opens, you need to select the same file with custom “Recovery”. Once the selection is confirmed, the installation process will begin. After this, the device will prompt you to reboot. The process will be completed.
How to flash Android via Recovery
Let's move on directly to the process of installing the firmware. I would like to note that all unofficial Android OS files created directly by users are installed only at their own peril and risk. If the decision to install non-native software is nevertheless made, you need to make sure that the firmware was written specifically for the smartphone model that you plan to reflash. If we are talking about stock firmware, then it is better not to bother installing CWM Recovery or TWRP. All manipulations that should be done are limited only to downloading the factory file and moving it to external card memory. The process after this will be similar to installing a custom Recovery. You need to go to the “Recovery” stock menu and select “Apply update from external storage” in it. Then you need to specify the firmware file and confirm the action. When the process is completed, you will need to complete one more step, which will avoid glitches and freezes when turning on and operating the smartphone. Immediately after the firmware is installed, you must select the “Wipe data/factory reset” item in the menu and confirm the operation. This way you can clear information about the previous software, as well as about those files that were on the device before the firmware process. When all these actions are completed, you will need to select the “Reboot system now” menu item. The device will reboot and the smartphone setup process will begin from scratch. If the switching process takes a long time and the device logo freezes, you will need to remember whether the settings reset item was performed after flashing.
Custom Android versions
How to flash Android via Recovery? All that remains is to figure out what to do with versions of operating systems that were written directly by device users. The answer to this question is quite simple: you need to repeat the entire process, performing the same manipulations in custom “Recovery”. The only difference is that the firmware file itself can now be placed not only on an external memory card, but also in the internal memory of the gadget. This will add convenience to the user if there is no flash card. Then you will have to select the “Apply update internal storage” item. It is also worth noting that in TWRP and CWM Recovery, the “Wipe data/factory reset” item was replaced with two separate items “Wipe cache” and “Wipe data”. After you manage to install Android through “Recovery”, you will need to select “Wipe Dalvik cache” in the modified TeamWin or ClockWorkMod menu. This will significantly increase the chances of successfully shutting down a device running a new OS.
How to restore stock firmware?
If the user does not like the new custom firmware, there is always the opportunity to return everything to its place. Many people today are interested in the question: how to restore Android through Recovery, namely through the stock version? The answer is hidden in the paragraph discussed above. Returning everything to its place occurs in the same way as making the initial changes. All you need to do is download the firmware from the manufacturer to the internal memory or flash card, and then select the appropriate item in the “Recovery” menu and execute full reset settings. In principle, there is nothing complicated about this.
There is actually nothing complicated about flashing a smartphone based on the Android operating system. But if you are not confident in your own abilities, then it is better not to get involved with these processes. If something still doesn’t work out, you can always restore the device’s firmware using the corresponding menu item. The main thing is to make a backup copy before flashing Android using Recovery. To do this you will need a custom “Recovery” and a little patience. The firmware recovery process takes quite a long time. If something doesn’t work out, you can always turn to specialists for help.
If, after flashing the Android operating system, problems arise in the operation of the device, you need to understand the current situation and find the reasons. Very often, due to their inexperience, users use pirated firmware, which does not allow for high-quality firmware. In this case, you are left for a long time without a reliable assistant - your smartphone or tablet.
Many users who have already encountered the problem of low-quality Android firmware have tried the method of flashing Android OS via recovery. This firmware method requires that you first install it on mobile device special program, which acts as a bootloader. Recovery is activated by clicking until a certain key combination is loaded (power button + volume button).
If the user chooses this method, he must find out . Regardless of the device, it comes with its own factory recovery. It can be launched after turning on the device. Also, the factory program can install and configure system updates from update. zip, and clean the entire system.
To flash your phone through recovery, you need to find and download the ClockworkMod Recovery program (installed in the internal memory of the device, in place of the factory version). It is intended: for flashing Android firmware and kernel, creating backup copies for system recovery, for other system updates. This utility differs significantly from its factory counterpart.
If the user is interested in how to flash Android through the recovery menu, this issue needs to be considered. Custom Recovery Menu is special application, which has a package of popular utilities. After installing the application on the device, it will be overwritten instead old version similar application.
Custom Recovery Menu is necessary for users who plan to flash their device very frequently.
