Hi All,
As you know they already released the Official Android 9.0 Pie for Huawei P20 Pro in EU.
I have the previous version of Android 8.1 CLT-L29.
My devices is:
-Rooted
-Bootloader unlocked.
Can I update via OTA to Android 9.0?
Is there any problem during the upgrade?
Will be still rooted and bootloader will be still unlocked?
If not what is method to do upgrade and still have a Root?
Thanks for your help!
You need to flash stock recovery first.
You will not continue to rooted.
Your bootloader will remain unlocked
Thanks for your kind answer.
Do you think should I update to 9.0 or should I stay with the previous version?
I am not that sure about the root process at the moment and I don't want to loose it.
I don't think there are that many new noticeable features. EMUI looks and behaves pretty much the same.
Hi all,
My Note 8 is currently running Android 9 (official), with baseband N950FXXU6DSD3. Given the phone is turning sluggish day by I thought it would be a good idea to downgrade to Android 8. Well, I downloaded Odion and the official firmware for N950F but Odin gave me an error. Googled and found it is probably because the baseband / bootloader is l6 and the firmware I was installing was l5. However, I couldnt find any official android 8 version with bootloader l6.
Just wondering if there is an alternate was of downgrading without tripping Knox/ Samsung Pay?
Thanks!

Nope not possible you're stuck on bootloader version 6 and there's no going backwards now!
There is no Android 8 rom with v6 bootloader? Also, if I choose OEM unlock will it still trip my Knox even if I install official firmware?

No OEM unlocking will not trip your Knox flag. However, if you install twrp and root the phone that's when you'll trip knox. If you're thinking that toggling the OEM button will allow you to downgrade backwards it's not going to happen! I personally don't know of any Android 8 on bootloader version 6. This is why we preach not to accept updates or buy a phone that's already been updated because there's just no going back once you update! We haven't found a way to do that and I don't think anyone is actually spending their time to try to figure that out either.
Ah ok. Thanks. Guess I am stuck on a laggy OS.
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, how do I downgrade without the microSD?
thx a lot
Hi guys, apparently the guy I bought the phone from second-hand had rooted android 10 with the sept 2020 security patch on it and installed some firmware from the F model to the N model which allowed the sim to work, my dumbass removed the magisk and root and flashed android 11s latest version with bootloader binary 6 which was the Korean version with odin , otherwise first it was the uae english version and I lost all sim capability,I wanted to update but didnt know this would end up happening at all
Hes saying he’ll be able to unlock it , root it install magisk and get the sim to work again but I doubt it as I asked many other flashing and unlocking professionals in the local market and they all refused to even try, I don’t know if there’s a way to root the Korean A11 one ui 3.1 firmware otherwise I’ll have to wait until a patch comes out
Please tell me if there is a way to downgrade from android 11 one ui 3.1 to android 10 which has bootloader version 5 or even to android 11 one ui 3.0 which would have bootloader version 5 which i think can be downgraded to android 10 with the same bootloader version 5 without bricking the device its very important to me, I'm really stressed out and could end up losing a lot of money, please someone knowledgeable help me, I'll be very greatful!! I am still a newbie to all this so please forgive me for my lack of knowledge where it may be!
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
