Installed Fairphone_FP3_8901.2.A.0110.20200109_01092024_user_release-key.zip with twrp-3.3.1-0_k4y0z-20200131-01-fp3.img.
Same result, installs fine but still freezes at “Fairphone” when booting.
Rebooted into stock recovery and did “Wipe data/factory reset”.
Wanted to “Reboot to System” from the recovery … got Fastboot Mode instead, and:
fastboot getvar current-slot current-slot: INVALID Finished. Total time: 0.007s
That’s when fastboot booting TWRP doesn’t work anymore, which even makes sense to me …
fastboot boot twrp-3.3.1-0_k4y0z-20200131-01-fp3.img Sending 'boot.img' (28570 KB) OKAY [ 0.771s] Booting FAILED (remote: 'unknown reason') fastboot: error: Command failed
At which point I’m wondering … How can I determine afterwards to which slot I installed the ZIP?
I had a look beforehand now and installed to slot a.
I rebooted into Fastboot Mode and
fastboot getvar current-slot current-slot: a Finished. Total time: 0.001s
So it seems it’s not the installing that makes the slot invalid.
Tried to boot the OS … freezes at “Fairphone”.
Rebooted into Fastboot Mode … slot is still a.
Is there anything I could check with fastboot or TWRP now?
