I tried to install [BOOT] 3.6.2_12-Mi12_v6.3_A13-cupid-skkk_b9e2a3ef (2) but nothing remains in black screen, then I decided either to redo the roms in fastboot or to change enough with twrp .. too many problems ..
- Download the ZIP file and unzip it on your PC.
- rename TWRP to twrp.img
- connect the phone to the PC in fastboot mode
- enter fastboot command to install TWRP
Code:
fastboot flash recovery_ab twrp.img
- run TWRP
- enter (Password/PIN/Pattern) of the lock screen when prompted
- install ROM
