I have an 'Advanced A4 2019' phone from BLU, and it's known to have spyware. I wanted to flash the phone's recovery with TWRP to install a custom ROM, but I can't seem to enable flashing. It runs android 8.1 at the moment.
Commands I've tried in fastboot:
fastboot getvar all
all:
Finished. Total time: 0.000s
fastboot oem device-info
FAILED (remote: 'unknown cmd.')
fastboot flashing lock
FAILED (remote: 'Not implement.')
.
(This is the good one)
fastboot flashing unlock
FAILED (remote: 'Not implemet.')
That's not my typo, it says not implemet. Also, its worth mentioning that the screen that pops up in fastboot is different from the normal one. Has the binary just been patched and there's no way to put my own OS on it? Thanks in advance
