Hello, owner of mi9t pro with rom with roll back index = 1. Can I proceed with the downgrade to rom with the same roll back index always = 1?
This even if the downgrade concerns the android version (from android 10 to android 9). Obviously proceeding with fastboot roms. Thanks

search and read. especially about downgrading the bootloader
I believe, if you have bootloader version 3 it's not possible to downgrade. I have downgraded international unlocked Note 9 back to ARL4 version back in January. There is a huge discussion here on xda how to do it, but unfortunately I think it can't be done in your case.

You can roll back to 9.6.7 as far as I've tested. Not sure about anything previous. Rollback is at 1, so technically not set to active. Make sure you downgrade using the proper global or china ROM based on your phone region. Only downgrade through fastboot ROM partitions, not using recovery versions. Finally, remember not to lock the bootloader during flashing.
Hello,
In order to unlock the bootloader and install a custom ROM, I need to downgrade from Android 10 beta to Android 9, since the latest beta doesn't work with the official ASUS unlock APK.
Problem is, when I try to flash the Android 9 image, I get the same error whether I try with adb or with the internal tool.
The message I get is 'This package is for "WW_Phone" devices. This is a "" '. Error status is 7.
My phone is neither unlocked nor rooted, so I don't get how it's not recognized.
Any help?

FYI, if you try to downgrade with the android P image found on the asus website, it won't work.
You have to download the image with file name starting with Q_P_UL...
we"re facing the same problem i can't downgrade my phone i forgot to unlock bootloader first. please help
You don't need to unlock the boooader for a simple downgrade. If it's still locked dowoad the image starting with Q_P... then put it in your phone's root folder.
can you please give me a download link for the Q_P_UL file tho

Hi ; my device is G975F Exynos and Original CSC is NEE. İ am on Android 11 Firmware which is G975FXXSEFUJ2.
i plan to go back to Android 10. i do not know my device's bootloader is unlocked or not. And also do not know is it available for bootloader unlocked or not.
What shall i do ? is it possible to go back to Android 10 for this device safely ?
I'm telling my own experience with my G973F, short answer: no
My phone has a unlocked bootloader and i have TWRP, i mistakenly flashed a wrong (lower) bootloader version, and my phone didn't boot anymore, i was only able to recover using download mode.
Older android versions have older bootloader, if you manage to install an older bootloader you phone will only give a message in the top of the screen saying something like "SYSTEM REV. CHECK FAIL DEVICE 8 BINARY 7"
You can only install a lower android version if that android rom works with your current installed bootloader
