Why is there no 3g on the cyanogenmod 12 firmware? How to install CyanogenMod on your Android without any problems. How to install: step-by-step instructions

Any smartphone, in fact, is the “little brother” of a full-fledged personal computer. It contains CPU, blocks random access memory, storage device, interface device controllers, etc. To manage this entire complex, a specific set of programs called the operating system is used. One of the most popular is Android from Google. It is installed on more than 70% of mobile devices. It’s not hard to guess that this system, more often than any other, is subject to various modifications, and not by developers, but by smartphone users themselves. As strange as it may sound, manufacturers mobile gadgets they are in no hurry to please the owners of their devices with the release of updates and optimizations of the operating system. The reason is quite simple - the desire to sell new smartphones, and not to refine a series of already sold ones.

What is "firmware"

Reading news from the world of smartphones, you can come across a number of specific terms. One of them is "firmware". It is interpreted in two ways: as a process of updating the device’s control software complex or as a set system files, intended for loading into the memory of a smartphone, i.e. a “distribution”, if we draw an analogy with computers. More often than not, the latter is implied. And, as stated earlier, this software package is created by craftsmen who make certain changes to the existing original firmware. Such solutions are called “custom”.

"Zoo" firmware

Despite the apparent diversity of existing software systems, they are all basically identical. Many of them simply copy interfaces ( appearance, method of interaction) solutions installed on other brands of smartphones. Yes, lovers Windows Phone can easily “turn” their Android phone into a gadget from Nokia, and connoisseurs of the creativity of Chinese developers will feel all the charm of a “Miui” or Lewa. Other custom ones, on the contrary, optimize some functions, for example, they use a graphics accelerator in all applications, increase the volume level, etc. But you should always remember that almost all of them are based on the basic official firmware.

"Cyanogen"

At the same time, there are a number of firmwares called CyanogenMod. The user part, menu and everything through which the owner interacts with the device have undergone significant modifications. Many key anti-spam and anti-virus features have also been changed. In a word, if a person wants to see the true capabilities of his smartphone, then he simply must figure out how to install the CyanogenMod firmware.

Distribution search

One of the main conditions for the successful installation of such a custom system is the selection of the correct firmware. Although initially these solutions are assembled to work with Qualcomm processors, nVidia and Intel, it is still possible to “make” them work with MTK. Where the distribution is downloaded from, as a rule, it will certainly indicate how to install CyanogenMod. Therefore, in order to avoid the need to restore the functionality of the phone’s software after an unsuccessful update, you need to carefully read the accompanying recommendations. Ideally, the firmware should be designed specifically for the same smartphone model.

How to install CyanogenMod firmware via Installer

There are several ways to download control software to a smartphone. The difference between them is that some require root access in advance, while others bypass this restriction by using the capabilities of the spoofed bootloader menu. Note that there is no “initially simple” method - each of them is simple and complex at the same time, so the user must choose one. Let's look at how to install CyanogenMod Installer. This software package consists of two blocks, the first of which is intended for installation on an Android device, and the second on a computer, to which a smartphone will be connected with a cable. After installing the client part on the phone, the program needs to be launched. A menu will appear warning you that all user data will be erased, i.e. a factory reset will occur. Next, it is suggested to connect the device to the computer and change the operating mode from “MTP Drive” to “RTR Camera”. After this, the cable can be temporarily disconnected.

In general, there are usually no difficulties with how to install CyanogenMod. After installing the appropriate computer application, you need to launch it. The Internet will be searched for the latest firmware. This takes from 5 to 15 minutes. If suitable option detected, the program will display a message stating that you need to connect the smartphone to the USB port, remembering to turn it off antivirus protection(some exploits are detected as malicious). Next, the “Recovery” file and gapps will begin downloading to the phone, providing integration with Google services. When everything is done, all you have to do is click on the Install button and wait for a window to appear with a message about successful installation.

Those who are not the first time interested in how to install CyanogenMod should be well aware that in Lately this method has lost its relevance. Moreover, it doesn't always work. The reason is that support for the search and download mechanism has been discontinued due to complaints from Google. Besides, computer part applications on the latest versions Windows systems does not work correctly.

Rolling up my sleeves...

An equally interesting way to install CyanogenMod is to prepare it yourself necessary files. First of all, you need to select a custom “Recovery”. This file can be found at network resources where it is discussed this model smartphone. When MediaTek processor it can be assembled using MTK Droid using your Boot.img and Recovery from a compatible device. After that, using you need to flash this file into your smartphone. Then go to “Recovery” by holding down the power button and “volume down”. After this, all that remains is to specify the previously downloaded CyanogenMod firmware file and install it. It is recommended to reset using the WIPE command.

Different versions

Sometimes smartphone owners ask the question: “How to install CyanogenMod 11?” This version is based on "Android 4.4 Kit-Kat". But the latter are 12.1 (system 5.1.1) and 13 (6.0, respectively). There is also CyanogenMod 10.1. How to install this software package? It is based on Android 4.3. Owners of mobile devices need to remember that the installation process is the same for all versions of Cyan. The main thing is to choose correct files for the device. Let us remind you how to install CyanogenMod 11. The procedure is as follows: select a custom “Recovery” and flash it into the phone; the found distribution intended for this model is written to the memory card; The system file is flashed from the recovery menu.

Peculiarities

Slower discharge, louder sound, stable network reception, interface acceleration, changed menu - all this is CyanogenMod. How to install applications on this system? It is this question that worries many who have not yet had time to work with this solution. In fact, there is nothing complicated about it. Since “Cyan” is based on the Android OS, the principles of operation remain the same: install the APK file - launch via a shortcut. Unless the latter can be located both on the main screen and in the application submenu, depending on the launcher.

Old means verified version

Let's take a quick look at CyanogenMod 7. How to install the firmware? It is based on the Android 2.3 OS, so the procedure is identical to the new Cyan. You need to select Wipe in custom “Recovery”, then “Select from SD card”, specify the downloaded file and click Install. After the “filling” is complete, you just have to click Reboot. Depending on the "Recovery" used, the names of these items may differ.

CyanogenMod 12.1 Android 5.1 Google Apps for Lollipop 5.1/5.1.1: These are the Gapps packages that are compatible with Android 5.1 Lollipop. If you ever install a Cyanogenmod custom ROM or any other custom ROM for that matter, you’d notice that these applications are missing. This is because they are licensed apps and as such the developers of these ROMs cannot include them in their custom ROMs. You must install Cyanogenmod Gapps on your own if you want to use the Google applications. Please note that these apps are not necessary for the booting or running of the custom ROM. You can see a.

CM12.1 Android 5.1.1 Gapps Features:

• Android 5.1 Support
• Android 5.1.1 support
• Latest Google Play Services 7.3.26
• Latest Google Play Store 5.4.12
• Google Search App/”OK Google” everywhere feature
• FaceLock for SmartLock
• Fully compatible with CM12 and CM12.1 ROM based on Android 5.1 and Android 5.1.1
• Compatible with all custom ROM based on Android 5.1.1 Lollipop.

Downloads

You are downloading GApps (Google Apps) for installing Play Store on your Android device with a custom ROM. If you do not install Gapps, you will not have Play Store for AOSP ROMs like CM12 or CM12.1! These Gapps packages are compatible with Android 5.1 and 5.1.1.

Installation

How to install CyangenMod 12.1 Gapps? So, you’ve downloaded the Gapps and want to install them on one of your Android smartphones, here’s what you need to do:

You will need to install the Google Applications packages via your device's recovery. These steps vary from device to device, but the general process is the same as that used to install CyanogenMod, or any other flashable zip:

1. Copy the gapps .zip-file to your /sdcard/
   • Using adb: adb push filename.zip /sdcard/
2. Reboot your device to recovery via any one of these methods: 1) using the power-on key combo for your device; 2) running adb reboot recovery from your computer.
3. Choose “install zip” or “Apply update” from within recovery, and navigate to the zip-file loaded earlier.
4. Reboot from recovery back to Android.

Troubleshooting

Google Apps packages are hardly ever supported by the CyanogenMod team, or by their distributors. The good thing is that there isn’t much that can go wrong when installing Gapps. If you are experiencing problems, here is a list of different things you can try (each one a bit more extreme/destructive than the last):

1. Reboot your device
2. Verify all apps are up-to-date in the Play Store
3. Re-flash the Gapps package (via recovery)
4. Wipe the /system partition and reinstall both CyanogenMod and Gapps (as long as if you don’t wipe /data, your data will be preserved)
5. Wipe /system , /data and /cache and reinstall both CyanogenMod and Gapps (this will delete all of your data, i.e. like you’re starting from a clean slate)

If you still have problems consider googling for alternative Google Apps installation package. Thanks for reading, everything you need to know about Cyanogenmod 12.1 Gapps–Google Apps Downloads/Installation for Android 5.1 Lollipop.

Samsung has offered official Android 4.4.2 firmware for Samsung Galaxy SIII (AT&T i747, d2att) back in June last year. We haven't heard anything about the official Android 5 firmware yet. Having tested the official version of Cyanogenmod 12.1 for AT&T Samsung Galaxy s3, based on Android 5.1 Lollipop, I realized that I don’t want to go back. This is the fastest firmware I've ever had. A significant role in this can be played by the refusal virtual machine Dalvik in favor of ART.

Fortunately, source Android is open (at least as far as Android is concerned) Open Source Project or AOSP), so you don't have to wait for updates from the manufacturer if enthusiasts have offered firmware for your device. Even the very popular Samsung Galaxy SIII (AT&T i747, d2att) was bypassed for a long time, not offering the official Cyanogenmod 12 firmware, although there were many unofficial Android 5 firmware on xda developers.

Although there are many different Android 5 firmware for AT&T Samsung Galaxy s3, I chose this one official version CyanogenMod 12.1. I prefer to avoid even unofficial versions of CyanogenMod. Even the official one involves installing a new bootloader, modem, and Google Apps. Despite the open source, there is always a risk of catching malware software. So of course official firmware may be preferable. On the other hand, official firmware is updated very rarely, so due to the presence of unpatched vulnerabilities, they may not be so secure when using the Internet on a smartphone.

I liked CyanogenMod 12.1 because when flashing, all applications were restored. True, I don’t know whether to thank the previous firmware CyanogenMod or Google for this, because... I used both options for synchronization. But it is Google that allows you to save a list of applications and, if desired, even their settings, so it is certainly synchronization with Google that helps restore applications. Although you have to log in to each application that requires logging in to your account again.

How to install Android 5.1 Lollipop (Cyanogenmod 12.1) firmware on Samsung Galaxy SIII (AT&T i747, d2att)

Warning: When flashing a phone, something can always go wrong. Use the firmware instructions below at your own risk.
As of May 26, 2015, Bluetooth may not work correctly on nightly builds of CyanogenMod 12.1. In addition, there may be problems with the camera, but you can install free application.

CyanogenMod notifies you when updates are available. They can be downloaded immediately from the settings menu. However, in the latest versions, when installing them directly from Android, the error "E: Zip file is corrupt! E: Error installing zio file "@/cache/recover/block.map"" appeared

You can still install the firmware update. To do this, you need to reboot into Recovery mode, then select Install ZIP and select the archive that is downloaded from the settings to the cmupdater folder on the phone.

Update (June 6, 2015)
I've been testing cm-12.1-20150529-NIGHTLY-d2att.zip for over a week now. Absolutely satisfied with everything, no problems arose at all. So I recommend installing CyanogenMod 12.1 on Samsung Galaxy s3 AT&T!

Update (June 16, 2015)
I've been testing cm-12.1-20150606-NIGHTLY-d2att.zip for over a week now. Everything is still stable. Applications are now easier to find, as they are displayed in alphabetical order, each next to the corresponding letter with which the application begins. "Updates over the air" (over the air or OTA updates) are now installed without error.

Update (June 24, 2015)
On previous firmware cm-12.1-20150606-NIGHTLY-d2att Google Apps suddenly started to glitch. In this case, an error constantly appeared, and the phone began to heat up very much, while the battery discharged quickly even after turning off data transfer and navigation. Installed cm-12.1-20150620-NIGHTLY-d2att.zip and new Banks GApps.

Update (June 26, 2015)
The camera did not work on the previous firmware cm-12.1-20150620-NIGHTLY-d2att. When using it, the error “I can’t connect to the camera” began to appear. I installed cm-12.1-20150625-NIGHTLY-d2att.zip, and then disabled recording of data with shooting coordinates in the settings. Photo and video work.

Update (December 28, 2015)
On the previous firmware cm-12.1-20150625-NIGHTLY-d2att.zip I didn’t like turning Wi-Fi on/off, although I couldn’t find fault with the rest. Installed cm-12.1-20151228-NIGHTLY-d2att.zip and

At the end of November the developers CyanogenMod started releasing the first batch of “nightly” CM13 firmware. Let me remind you that they were already created at Android based 6.0 Marshmallow, although in their current state they do not offer any new features compared to CM12 or CM12.1. The functionality update should happen in the next few months.

If you have already installed CyanogenMod 12/12.1 firmware on your Android device, then you do not have serious reasons to install the CM13 update. As I noted above, you will not get any new features, however new firmware has many fixes and performance improvements compared to Lollipop builds.

By tradition, the CM development team offers two different build options: “nightly” and stable. As the name suggests, the first ones are released every night by the CyanogenMod team. In other words, they have experimental features without the promise that it will work stably and there will be no performance issues.

After several weeks or even months of testing, the CM team releases a stable build for a range of supported devices. Release final version firmware takes several months, so if you don’t want to wait that long, then if you really want to, you can use the “nightly” build a few weeks after it appears, since this option will probably work quite stably. If you are interested in this, you can download the “nightly” and stable versions of the CyanogenMod 13 firmware from here.

By default, CyanogenMod developers do not include any stock apps from Google due to licensing issues. Therefore, after installing the firmware, in any case you will have to use additional package Gapps to have on your smartphone or tablet Google applications Play, Maps and other services from Google. Installing the Gapps package is exactly like installing any zip file using custom recovery. Compatible Gapps package for CyanogenMod 13 (Android 6.0) can be downloaded from here.

Preparing to install CyanogenMod:

It definitely requires root rights on your Android device, as well as a custom recovery installed (TWRP, for example). There is no other option for installing CM firmware. It's better to make sure that you have on your smartphone latest version TWRP, since older versions of recovery are not compatible with Marshmallow firmware and you will not be able to install the CM13 zip file.

Additionally, we can recommend reading in a special forum thread the reviews of other users with exactly the same Android device, who have already installed and tested the CM13 firmware. This will give you a good idea of ​​the capabilities of the build itself and the problems that may suddenly arise.

Be sure to do this before installing the firmware backup copy all data. This includes contacts, messages, photos, music and other important documents and files. This can be easily done using Titanium Backup, although you may run into compatibility issues when trying to install it on CyanogenMod 13.

On some devices, you may have to update the bootloader and flash the radio module to the latest available versions, but be sure to do so before installing the CM firmware. Failure to comply with this condition may lead to problems with the camera and sensors. In general, your Android device is unlikely to work properly.

Step 1: Copy the CyanogenMod 13 and Gapps firmware zip files to the memory of your smartphone or tablet. I always recommend double-checking whether you have downloaded the correct version of CM firmware and Gapps package.

Step 2: After copying the files, you need to reboot your device into recovery mode. Usually, to do this, you need to turn off your Android smartphone (tablet), then hold down the volume up and power buttons at the same time. However, this method is not always suitable, and therefore, as a piece of advice, install the Quick Reboot application from Google Play and click Recovery from the suggested options in the program menu. There is another option using your computer and the Android SDK, but it is more labor-intensive.

Step 3: After the device boots into recovery mode, you will need to select the commands wipe the /data and /system partitions (pictured). After this we reset the settings (). Do not use the data clearing or clearing option internal memory devices. To format the system partition, select "Advanced Wipe" then "System" from the list of partitions. Confirm your choice by moving the slider to the right.

Step 4: Now we proceed directly to installing the CyanogenMod firmware. Click on the “Install” button in TWRP, then specify the zip file with the CM firmware that you copied in step 1. If you cannot find this file, then be sure to double-check if you are in the /sdcard subdirectory.

Step 5: Reboot your device by clicking on the “Reboot system” option. The first reboot may take longer than usual, so be patient. If the system does not boot within 10-15 minutes, then you will have to repeat the previous steps of installing the firmware.

Step 6: Once you see the desktop, give your Android device a few more minutes to fully load all the necessary processes. And after that, you will again have to reboot into recovery mode to install the Gapps package. The installation is identical, but you need to select a different zip file, which you also copied to memory in step 1.

Step 7: After installing the zip file, you can reboot the system again. You'll need to sign in to your Google account and download your favorite apps and games.

If you suddenly installed the “nightly” build of CM13, then updating the firmware to a newer version will not require you to complete the installation process - you need to complete steps 4-7. This will save you from formatting the system partition and clearing data, and you will not lose already installed applications.

In contact with

It is common practice in the world to compare Android and iOS. The main difference is the attitude towards the openness of the system for the user. If iOS does not even allow you to view individual folders on the device, then Android file the system is accessible to the user. However, only at first glance it seems that Android developers allow you to do anything with their OS: many important and required functions remain unavailable. Therefore, CyanogenMod firmware has become popular among advanced users. For information on how to install, update and, if necessary, remove the firmware, read our article.

What is CyanogenMod?

СyanogenMod is an alternative Android firmware that expands functionality operating system. The firmware has gained popularity: as of 2016, CyanogenMod is installed on 14 million devices.

It all started with the fact that a simple programmer Steven Kondik posted on xda-developers.com, the largest site with custom firmware for Android, his development for HTC smartphone Dream. He didn’t think long about the name and took his nickname - Cyanogen, adding Mod to it. Steven Kondik did not imagine that anyone would be interested in his development, but already in the first days users responded positively to the firmware. Then the programmer, in a creative impulse, began intensively refining CyanogenMod, posting several updates per day on xda-developers.com.

Then Steven Kondik released CyanogenMod on Github, a collaborative development service. Then other programmers joined in improving the project, bringing their ideas and developments. Over time, it became clear that CyanogenMod had turned from an amateur firmware into an exceptional project. The capabilities of CyanogenMod did mobile device more functional than any other firmware.

Advantages

Why do users love CyanogenMod so much?

1. High performance. CyanogenMod, thanks to its optimization, significantly improves the performance of the device. Both the menu and heavy games work on this firmware much faster and smoother than on the standard one. As an example, consider the Nexus 4, which gives 15–16 thousand points on standard firmware Antutu Benchmark. After installation, Cyanogen makes 21 thousand points. In addition, Cyanogen allows advanced users to change the processor operation scheme and control its frequency at their discretion. There are five modes: Interactive - standard frequency distribution, increases when the screen is turned on; Ondemand - less productive, more energy efficient; Userspace - allows you to configure everything yourself; Powersave - minimum processor frequency, maximum energy saving; Performance - maximum processor frequency, best performance, but high power consumption.
2. The only option is to install a new one Android version for older devices. Few manufacturers support their devices even for 4–5 years, releasing Android firmware 5 and 6, so CyanogenMod is the only way to install on such devices Android Lollipop and Marshmallow. Cyanogen also allows you to get rid of the manufacturer’s pre-installed firmware, for example, Samsung’s TouchWiz.
3. Customizable appearance. CyanogenMod makes it possible to change the design of every detail of the interface to your liking. PlayMarket has thousands of custom theme options. The firmware also supports the original Android theme (Android Holo up to version 12 and Google Material Design in versions 12 and 13), unlike the official firmware of device manufacturers.
4. System openness. Standard Android firmware has various restrictions for users. CyanogenMod eliminates these restrictions, thanks to which it has a Free Lossless Audio Codec, a compressed cache, a large list of APNs, an OpenVPN client and a reboot menu. However, this advantage is only for knowledgeable and skilled people, because the device can be accidentally broken.

Firmware versions

The latest version of CyanogenMod is the thirteenth version, based on Android 6.0 Marshmallow. Each a new version CyanogenMod is developed under Android update. In addition, the developers support and constantly update all versions simultaneously, releasing new builds of the project. There are six types of CyanogenMod builds:

1. Experimental - experimental firmware versions for testing new ideas. These versions are extremely unstable, have an abundance of bugs and are needed only by developers for testing.
2. Nightly - daily updates, the result of a day's work by programmers. Like Experimental, they exist only for developers, so that enthusiasts can follow the development of the project and help it with new ideas and suggestions.
3. Millie stone is a raw version that collects all the innovations to test their interaction.
4. Snapshot is an already developed assembly suitable for use. Usually, not all bugs have been caught and not all errors have been fixed.
5. Release Candidaty (RC) is an almost finished firmware version. The developers check for errors, performance and stability one last time.
6. Stable is the final, stable version of CyanogenMod.

If you are a simple user who wants to install CyanogenMod, then you should choose a stable firmware version. This guarantees no errors and functionality. But for the sake of useful functions, which are not yet in the stable version, you can also try the developer versions. But such firmware is almost impossible to use - there are too many errors.

How to install: step-by-step instructions

Please note: installing CyanogenMod will void your warranty! This applies not only to Cyanogen, but also to any other custom firmware. There are certain ways to hide traces of third-party firmware, but the methods are unreliable and do not always work. So unless you're willing to forfeit your warranty, don't take the risk.

The installation of CyanogenMod is non-standard and complicated for untrained users: it involves more than 10 steps. Updating the system isn't the most intuitive either. Of course, there is an easy way to install the firmware, but this is far from the best option. The latest version of CyanogenMod is automatically downloaded, which is not always stable, which may result in errors. But since not everyone will want to spend time on a more complex method, we will look at this option.

Easy installation

1. First, check if your device is supported. To do this, follow the link: http://wiki.cyanogenmod.org/w/CyanogenMod_Installer#Supported_Devices and view the list of supported devices.
2. In your smartphone settings, enable USB debugging ( Special abilities-> For developers -> USB debugging).
3. Download the CyanogenModInstaller app on your smartphone from Google Play.
4. Download to your computer special program for Windows (Vista/7/8): http://beta.download.cyanogenmod.org/install.
5. Turn on the application on your smartphone and follow the instructions in the program.
6. Connect your device to your computer via USB.
7. Turn on the program on your computer.
8. The program itself will start downloading the files necessary for the firmware. When everything is downloaded, you will see the message “Everything is ready”.
9. Click on the “Install” button.
10. When the firmware installation is complete, the program will notify you with the message “Installation complete”.
11. Ready.

The hard way

1. First you need to get Root rights (remove restrictions imposed by Android developers). Let's do this using the Framaroot program. Download Framaroot 1.9.1 from the Internet, install it and run it. If your antivirus issues a warning, click Allow.
2. Now you need to unlock the Android bootloader. The best way to do this is the BootUnlocker program. You can download the application directly from Google Play. Launch the program and click the “Unlock” button. The bootloader will be unlocked.
3. You need to install Custom Recovery. Let's look at its installation using TWRP (Team Win Recovery Project) as an example.
   
4. Let's start installing CyanogenMod.
   
5. As soon as the installation is completed, reboot the system. If everything went well, an empty desktop will open. If not, the phone will not boot. In this case, you need to enter Recovery mode again, install the new firmware, but only enable full Wipe.
6. The last thing left is to install Google Play. To do this, download the Gapps package (http://opengapps.org), move them to the root folder and install them in the same way as the firmware itself, via Recovery.
7. Ready!

Video: how to install CyanogenMod firmware?

Is it possible to install CyanogenMod on an unsupported device?

The answer is clear: no. CyanogenMod Installer will simply write that your device is not supported. If you install it manually, there may be a lot of problems, even to the point where the phone or tablet stops working. If the device could run firmware, the developers would have added it to their list anyway.

How to update firmware

There are also two ways to update CyaongenMod.

Easy way

This method works for Cyanogen versions 10.0 and higher. Everything is extremely simple: open the settings, go to “About phone”, then “CyanogenMod update”. The device will boot on its own Last update and install it. During the process, the smartphone will reboot several times. All data will be saved.

Manual option

Please note: you should not update your device to more than one version of CyanogenMod at a time (for example, from CM version 10.0 to version 10.2). Unpredictable errors may appear and incorrect work firmware. It is also not recommended to roll back the device to earlier versions of CM (for example, from 10.2 to 10.1). Sometimes it leads to an error with the smartphone endlessly rebooting. For any downgrade, you must first do a Wipe Data/Factory Reset.

It's almost always better to use the easy update method as you're less likely to do something wrong. However, if you have Cyanogen version below the tenth version, and also if you use third-party add-ons (add-ons), you will have to use a complex method, since the standard update does not allow you to immediately install add-ons to the firmware.

1. To get started, download the latest stable version (or whatever version you need) of CyanogenMod and the latest version of the Gapps package.
2. Turn on Recovery mode.
3. Install the firmware first, then the zip archive with Gapps, and then third-party addons. There is no need to Wape, so all data is retained during the update.
4. Ready.

When updating again, there is no need to reinstall Gapps, since the data is saved, but addons will have to be installed manually.

In addition, only with the complex option can you choose which update to install (which cannot be done with in a simple way installations).

How to remove if necessary

If you decide to return everything as it was, you need to reinstall the firmware again, but this time replace CyanogenMod with the stock firmware from the manufacturer of your device. You can download such firmware from the manufacturer’s official website.

1. When you download the firmware, save the archive in the root directory of the device
2. Enable Recovery mode (press and hold the power button and volume up button while starting the device).
3. Check all the Wipe boxes. Please note that all data will be deleted.
4. Then install the downloaded archive with the official firmware.
5. Wait for the installation to complete.
6. Reboot your device.
7. Ready.

Sometimes returning to the device's native firmware erases all traces of the presence of CyanogenMod, in which case the warranty will not be nullified. However, you should not count on this, as it depends on luck and the carelessness of the support staff. The rules for providing warranty service prohibit changing the manufacturer's firmware.

CyanogenMod is an interesting firmware that has grown from an amateur craft to a serious and ambitious project, which has no analogue in the world. CM allows you to do things with the device that no official firmware allows. But only advanced and knowledgeable users should install it, since open systems are unsafe. In addition, the phone may malfunction, and warranty service will be unavailable. However, if you don't have enough standard features smartphone or tablet in stock Android firmware, if you are ready to learn and develop, are ready to spend time and effort to overcome errors that arise, then you definitely need to flash your device with CyanogenMod. According to some users, CyanogenMod is the highest point in the development of mobile devices.
