Details for thanks, I’m just saving up for a new camera and light, are in the channel header in the Support the channel section.
ATTENTION!!! Remember, if you have Android 5.1, 6, 7 and higher, before resetting the settings or flashing the firmware, you must exit Google accounts, Samsung Account, Mi Account, Flyme, and others, if this is not done, after the reset the corresponding lock will work, which is EXTREMELY HARD to remove, and sometimes even impossible!!
