Hello Everyone,
I'm trying to get the EMUI 9.1 update on my P20 Pro (Canadian Version) and the system download the updates and it reboot, and gets back to the previous state 9.0 and it asks to upgrade again.
I tried upgrade using the HiSuite and also gets the same issue.
Do you guys know if with the bootloader unlocked and Magisk Manager installed on my boot partition affect this upgrade ?
Thank you
No
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
Hello everyone,
I have a Xiaomi 11T Pro (Model number - 2107113SG, 8GB ram, 256GB rom, Snapdragon 888 ; european model).
Currently, the phone is running MIUI 13 (Android 12, 13.0.21.0.SKDEUXM with no updates available), but i want to flash MIUI 14 (Android 13, 14.0.5.0.TKDEUXM - already tried to use recovery ROM method but i got an error: can't verify update - can't install this stable ROM - i know 13.0.21.0.SKDEUXM has issues).
I understand the process of flashing (Installing ADB Drivers, enabling USB debugging, unlocking bootloader, booting phone to fastboot mode and then flashing firmware with either MiFlashtool or .bat script).
All of the data on the phone is backupped (i don't mind any data loss)
But i happen to have two big questions.
1: Will I be able to re-lock the bootloader after I flash the firmware? Firmware is official and it is also EEA version.
2: Will I be able to recieve OTA updates after I flash the firmware? Or the phone will recognise that I flashed the firmware and OTA updates will be blocked?
Thanks in advance.
You can flash any stock rom and version and re lock the bootloader on this device.
And the OTA will work.
