GSI / Treble related question

Hi Guys,
i am currently flashing different GSI to my Galaxy A20e.
Since the experimental TWRP only worked after i flashed an Adroid 9 based Stock firmware, i was until now also only able to flash Pie based GSI using TWRP.
The Q Based GSI won´t boot.
Does it make a difference wich stock FW i flashed before installing TWRP and flashing the GSI.
Is a flashed Q Stock FW required to install Q based GSI?
As far as i thought the Stock FW does not affect these parts, since i was able to flash the GSI even after breaking the installed FW..
Thanks in advance!

Can i downgrade from android 11 to android 10?

Hi is it safe if i try to downgrade my rom from miui android 11 to miui android 10 using mi flash tool? I have unlocked bootloader and currently on custom rom android 11. Im planning to flash miui android 11 and then flash miui android 10.
Hi @samcess
I just downgraded my Curtana from Android 11 to Android 10 MIUI 12 using OrangeFox recovery. I was also very nervous about downgrading through a custom recovery and MiFlash doesn't worth that much effort (imagine being unsuccessful with a locked bootloader, I'm not scaring you though).
Here's what I did but plz do it at your responsibility-
1.Download latest Android 10 build for Curtana i.e. 12.0.6.0 from xiaomifirmwareupdater.com
2. Boot to OFox recovery>Wipe>wipe Dalvik/cache,Cache, Data, Internal Storage. Also FORMAT DATA.
3. Flash the recovery ROM zip.
4. Wipe dalvik, Cache.
5. Reboot to system
PS: I was on Android 11 based Evolution X ROM when I downgraded to Android 10. So it's kind of Android 11 EvoX downgraded to Android 10 MIUI 12.
You can switch to a non-MIUI A11 ROM before downgrading.

Need android 10 based custom rom

Hello, I have a huge problem. Custom recovery can't flash ozip files and can't flash ofp files.
Device bricked, when I try to install stock rom recovery it can't boot that recovery, only stands on realme logo.. Orange fox recovery works and my idea is to flash custom rom because it can't flash stock rom..
Problem is every custom rom here is android 11 based and to flash it you need to be previuos on android 11 based rom.. I was on android 10 realme ui 1.
Does anyone have maybe android 10 based custom rom that I could flash using orange fox recovery?

[QUESTION] How to upgrade kernel in Huawei P20 Lite?

I want to upgrade kernel in Huawei P20 Lite from 4.9.111 ---> 4.9.148.
I tried to flash kernel 4.9.148 but, after flashing the phone got stuck at bootloop untill I rolled back to kernel 4.9.111.
You may say why I need to upgrade kernel to 4.9.148? Because I have Android 12.1 GSI installed with unlocked bootloader and I wanted to install Android 13 but, it didn't work and the phone got stuck at bootloop even with VNDKLite GSI, after that I saw in some thread that I must have kernel 4.9.148 in order to get Android 13 GSI working on Huawei.
I don't want to flash EMUI 9.1 Firmware because it will lead to relock bootloader. Anyone knows how can I upgrade kernel?
Note: Current firmware base installed is EMUI 9.0 with kernel 4.9.111 on Android 12.1 GSI and all GSIs work up to Android 12.1.
