I have installed my Fairphone 4 according to these instructions.
Unfortunately, the phone always restarted after that. I was able to go into recovery mode once from /e/ and do a wipe.
Now I can not do anything on the phone. I only get into the fastboot screen.
The message is “DEVICE STATE - locked”.
Whether I select “Restart bootloader” or “Recovery Mode”, it always reboots into this mode.
That sounds like something went wrong while the partitions got flashed.
Instead of trying to debug this, I would suggest just starting the whole installation again from the top.
Try to copy and paste those lines one by one, when you get to that step
I have now run the installation again.
Once completely and also test only with the “b” variants, because the phone is in “b” mode.
The only thing that works is the /e/ recovery mode.
In recovery mode I get the following messages
E: Failed to bind mount /mnt/staging/emulated/media/0 to /storage/emulated: No such file or directory
E: recvmsg failed (No buffer space vailable)
E: Open failed: /metadata/ota: No such file or directory
E: Couldn´t mount Metadata
E: [libfs_mgr]Faile to find block devie for partition
Hello
Thanks guys, the same problems with A/B and locked fastboot I also had.
On the pc nothing , on the laptop (win7) nothing, read a bit here and already it works on the pc
Good job and thanks a lot
Only as a note:
Those people to whom the “fastboot --set-active” and “fastboot flash unlock” commands yield to an error like “is not allowed in Lock State” should continue at this topic Trapped in fastboot mode with locked bootloader and corrupted /e/ OS .
Unfortunately there is no solution for this issue up to now.
Only if they aren’t able to boot their phone normally.
If the phone is still bootable enabling OEM unlocking in Settings → System → Developer options is still enough to get that capability back.
Had the same issue driving me mad, tried everything including switching active from a to b and back again.
Finally got things working, I used IMG-e-0.21-r-20220123158735-stable-FP4.zip first but then switched to IMG-e-0.21-r-20220112156786-stable-FP4.zip . The older release now boots
