I’ve got into trouble with my FP3 after install/ uninstall of Magisk.
Now the phone cannot even boot into the system, just into recovery (TWRP) or the Fairphone logo.
Here is a summary of the steps that led to here.
Booted into and subsequently installed TWRP (not by flashing, but with the installer). All was fine. Made a back up.
Installed Magisk and tried to flash the patched boot image. Worked on slot A, but not on B where I’ve got repeatedly an error.
After installing Magisk TWRP suddenly vanished and the e-Recovery took over.
Uninstalled Magisk successfully, but after I couldn’t boot into system-slot A.
Did factory reset - nothing.
Via ADB managed to boot into the B s!ot.
Tried restoring boot/system/vendor from the backup via TWRP and then ended nowhere - boot neither in A nor in B, just TWRP or the Fairphone logo (bizarrely the /e/ Recovery has vanished and TWRP reappeared).
Any ideas if, and how, I could get out of here?
Do I have to revert in install the FP OS? If yes, any suggestion of a recent and non buggy download?
Or can I install afresh via ADB the /e/? Will that resolve whatever mess is now in the boot partition?
Thank you in advance for any help.
P.S. Turned out TWRP is only in slot B, on slot A is still the /e/ Recovery
