Hi guys so to install the latest ROM on MI 10 umi : you need to boot 3.4.2B-1206 but not install it. Because it breaks the system boot and would boot only to bootloader.
Situation is : 3.4.2B-1206 can decrypt data but break system boot.
Also be careful : for it to decrypt you'll have to not use fingerprint nor pin code. (you just disable it everytime you wanna go to TWRP, for updating for example).
3.4.0 Little Turtle is OK with booting system but don't have data decryption. Some people use it without problem and install EU rom updates with USB OTG Key
Steps:
- Unlock phone
- Go to fastboot
- Plug the phone to computer and open up a command prompt where adb and fastboot.exe are
- Have the TWRP 3.4.2B-1206 available
- Enter in command line
Code:
fastboot boot twrp3.4.2B-1206
- Booting it take approximately 60+ sec
- Auto decrypt if no fingerprint and no pin (remove temporary).
- (first time xiaomi EU rom? Format data. Not wipe, FORMAT. Of course move back the rom from PC to phone storage)
- Install EU rom (who contains TWRP little turtle) and reboot (no additional wipe needed)
- First boot time is very very long. Go take a coffee.
- If by mistake your phone stick to fastboot because you flashed 3.4.2B-1206 just reflash little turtle's TWRP
