Thanks @Aron (I’m still getting trauma from that anydesk session haha)
Here’s a starting point for anyone to continue.
3.0.2, No Gapps, patched
- device admin removed
- adb restrictions lifted
- background app kill prevention patch applied
https://github.com/alltechdev/awesome-qin-f21-pro/releases/download/v3/vbmeta.bin
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.bin
(won’t be able to mount r/w without)
Haven’t tested flashing with spflashtool, only fastboot, but I don’t see why it shouldn’t work.
Will add it to the mega guide later.
