Could we downgrade Eu Rom 8.8.16 to Eu Rom 8.8.9 or other version (etc. China Stable 9.6)? Anti-rollback system is confusing my head.
Thanks.

run this command

fastboot getvar anti

If 3 you are safe and can roll back to previous versions of firmware

If 4 that rollback of firmware can lead to "brick"

you have no anti rollback, so you can flash anything but if you flash a xiaomi china firmware you will not be able to downgrade again

Finally, I got it work and installed MIUI 10 STABLE RELEASE

1 - I run commands:
fastboot flash recovery twrp.img
fastboot boot twrp.img

- but it asks for password
- I cancel and wipe data
- I install ROM (installation ends with errors)
- I restart
- phone boots in fastboot screen

2- I run commands again:
fastboot flash recovery twrp.img
fastboot boot twrp.img

-now twrp dose not asks for password
-I install twrp.img
-I install ROM
- Restart

Every thing works ok :)

twrp 3.2.2-1 for Redmi 6 Pro download link

- Must unlock Redmi 6 Pro
- Backup first, otherwise you would lose your data.

How do you install ROM if you Wipe Data you lose all the files in internal storage on device

Memory card for example. Anyways wipe data doesn't remove files from internal storage. Wipe internal storage or factory reset does.

Hi, don't flash twrp right away from your pc Try these steps:

1. boot into the twrp directly (fastboot boot twrp.img)
2. Wipe data (do this first)
3. Advanced wipe (wipe all entries except the last two items)
4. Mount the redmi and transfer the twrp onto the phone
5. Flash the .img files directly from within twrp, make sure to choose "recovery"
6. Reboot into twrp

then from there mount the phone again and transfer the ROM.zip of your choice, install and reboot.
