GSI fastboot flash system system.img DOES NOT WORK on Android 10 or 11 on Pixel 3 XL!

So TWRP does not work on PIxel 3 XL with Android 10 or 11 but I also found out GSI does not flash also on Android 10 or 11. So make sure to downgrade to Android 9 when trying to install GSI ROMs otherwise you will get error with fastboot.

This could be an issue with Pixel 4 series also!

Also you need to disable verifcation by:

fastboot flash vbmeta vbmeta.img

BEFORE even trying

fastboot boot twrp.img
