Bootloop after fastboot flash vbmeta

Help Fairphone 4
#1

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?

What vbmeta.IMG is it?

Since you tried to reflash to stock you probably don’t need a A.0128 vbmeta.img anymore, right?! :thinking:

What errors did you get when running the flash_fp4_factory.command script?
If you didn’t get any have you tried changing the slot fastboot --set-active=a? That part of the script is still broken and won’t execute if you don’t have fastboot in your $PATH (if you are on Linux, no idea how that works on Windows :man_shrugging:)… :roll_eyes:
