I would like to use this phone for experimentation with android development and learning about android on a cheap device without risk of breaking my main phone. To do this I would like it rooted and as a bonus with a custom recovery so I can test custom ROMs.
State of device:
- Unlocked bootloader
- Unchanged ROM
- Unchanged Recovery
- OEM unlocking enabled
- USB debugging enabled
What I have tried:
Flashing recovery images with fastboot
fastboot flash recovery recovery.imgwith some TWRP and CWM recovery images all yield:
target reported max download size of 134217728 bytes sending 'recovery' (4690 KB)... OKAY [ 0.169s] writing 'recovery'... OKAY [ 0.276s] finished. total time: 0.448s
or similar. Then I restart phone and select boot into recovery mode. The phone hangs for a small while before restarting and booting into the normal OS. On restart into recovery the unchanged recovery is there still.
Various 'one-tap' methods
All of which were unsuccessful. If needed I can give details.
Installing SuperSU zip from recovery
In a futile attempt I tried to use the android recovery to push a SuperSU zip with its update from zip option. I knew this wouldn't work but I found something interesting. On the
Apply update from SD cardoption I get an error saying
couldn't mount /sdcard
Booting recovery images with fastboot
I have tried the
fastboot boot recovery.imgcommand to try to boot directly into the images. I get this
downloading 'boot.img'... OKAY [ 0.211s] booting... OKAY [ 0.047s] finished. total time: 0.261s
output but the device just restarts and boots normally into the normal OS.
What I would like from this question (In order of importance):
- A way to root the device
- A way to access a custom recovery (even if temporary)
- Ability to install custom ROMs
- A permanent custom recovery
