I have a device called "EXEQ SET": http://www.exeq.ru/produkcija/pristavki/os-android/set.html
It runs Android 4.1.1.
It is spitting out errors like this every other second, making the device almost unusable:
The process com.google.process.gapps has stopped The process 'Google Play Store Services' has stopped The process 'Launcher' has stopped
Here's what I have tried to re-flash the device:
I turned off the device, then pressed the key combination to boot into bootloader/recovery mode, which is Home+Power according to "documentation". The power led lights up, but the screen is completely blank and the device doesn't seem to turn on. I have to hold the power button for a few seconds to turn it off from this state.
When I go to Developer options menu and turn it on, it immediately switches the developer options menu off. This isn't instantly visibly, I have to re-enter the menu for it to refresh.
adb devices and
fastboot devices commands give empty output when the device is turned on and on all stages of boot.
When doing a factory reset from menu, the button simply does nothing.
I suspect this might be because of some malware.
Are there any other ways of doing a factory reset?
