Hello,
I have a tablet galaxy tab a 8 sm-t290 that I updated to Android 11, but now I want to downgrade it to Android 9. Could you please guide me through the process of how to do this?
You can't, because new bootloader can't be downgraded to a supported unlockable version

I have the tablet NVIDIA SHIELD K1 (WiFi only). By OTA it is updated to Android 7.0. Now I have problems with the app DJI GO4 (Mavic Pro). The app is not compatible with Android 7.0 on the NVIDIA tablet.
Now I would downgrade to Android 6.0.1. The boot loader must be unlocked.
TowelRoot does not go for the NVIDIA with Android 7.0.
Who can help me to unlock the bootloader, then I can flash a firmware images of Android 6.0.1.
Hi,
I have just got the p10 lite Asia pacific version model was-lx2c636b102. I did not find any thread or information about this model. Is it possible to root this device and use the latest version of android? Currently, the phone has Android 7 EMUI 5.1, 2017 security patch!
Can you help me?
No response!!
Use DC Unlocker to get the bootloader unlock code, then flash any of the custom roms available since last official rom offered by Huawei is 8.0.0

Back story
I stopped receiving updates a while back and my phone was basically stuck on update FRD-L19C432B405
I decided to upgrade my device but all guides i could find require the bootloader to be unlocked. Unfortunately, as you all know, this has become quite a challenge and is basically off the table as far as official ways are concerned.
The only way i could find was to use the built in updater/eRecovery and a bit of trickery...
Requirements
1. Honor 8 FRD_L19
2. Firmware Finder for Huawei - app installed on your phone
Upgrade process from EMUI v7 (FRD_L19C432B405) to v8 (FRD_L19C432B562)
1. flash FRD-L19C432B406 partial udate (243.2 MB)
- use FFfH to find and flash the firmware
- I used the DNS-auto approach inside the app to find the update
- this will bring the system to EMUI 5.0.3 and enable the next step
2. flash FRD_L19C432B562 FullOTA-MF-PV (2.6 GB)
- use FFfH to find the firmware and flash via eRecovery
- here the DNS-auto approach didn't work so i opted for the eRecovery instead
- i found multiple firmware with the same name, so try to remember which one you tried and if that one doesn't work try the next one and so on.
Thats it, you now have OREO without root or unlocking the bootloader. Enjoy
