I had some issue with booting after updating a rooted FP4 on otherwise stock firmware. Someone told me to run this command:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
Now the device constantly bootloops, no matter what I do. The only thing I can boot is TWRP. I cannot boot stock boot.img, I cannot boot magisk patched boot.img.
I even did a flash_all.sh using the factory reset image, and even that didn’t help.
How can I fix this?
