You need A/B Gsi and not A-only, flash OneUI 2 stock fully and then flash A/B GSI without wipe

[Kazryu]

[g0didit]

How to remount /system to RW on stock rooted (Magisk) image?

 

[Voytec83]

Great job @prashantp01, especially U don't personally have A750x device!
Let's hope it is just the first step?
Kernel works great with custom OneUI 2.0 roms

 

[AmanDevil77]

I'm getting problem Booting ExpressLuke GSI's after updating to 10 ( they used to boot fine before one UI 2.0) other gsi boot with your kernal but they are having same problem like no working camera and no Web page loading. Idk what's causing it.

Just Install the payments app manually download the apk and put it in system/app via twrp's file manager and you will be able to use the phone

It happend to me to. I think in the script it deletes KnoxGuard and that happens.
There is solution when that happens:
https://forum.xda-developers.com/android/general/phone-locked-payment-service-uninstalled-t4018177

I didn't try it,but if anybody needs it...

I did try to instal it like boot.img in twrp, but i had random reebots here an there so i went back to stock.
