Didn't try GPay or flashing anything else yet
Ok following my last bad try, I again reinstall from scratch the whole system, I will resume the proper commands, I did here:
- Start from Miui global 12.0.3 (so android 10)
- Install TWRP:
- Boot to fastboot (using Power & Vol -)
- Use this command: "fastboot flash recovery twrp_grus-MI9SE_3.5.A9_07-03-2021_d-bl.img"
- I have restarted under Miui after using this (wrong) command: "fastboot boot recovery"
- Reboot again under Fastboot
- Try to reboot under TRWP with success using this command: "fastboot boot twrp_grus-MI9SE_3.5.A9_07-03-2021_d-bl.img"
- Decryption possible
- Reboot to Miui using TWRP to backup images, etc...
- Reboot again to fastboot
- Reboot again into TRWP using fastboot cmd
- Decrypt without pb
- Under TWRP place xiaomi.eu WEEKLY 20.12.9 - Android 10 from computer to the phone internal storage
- Wipe / swipe to factory reset
- Install Weekly 20.12.9 Rom
- Wipe cache+dalvik at the end of the flashing
- Reboot to Weekly 20.12.9
- Here I went to the Mi-recovery...
- Back again to fastboot and flash vbmeta using "fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img"
- And ****ed again, because the recovery wont decrypt anymore using the pattern !
