I’ve got A Fairohone 4 wich was running good with /E/ OS.
I wanted to tried LineageOS bue everything went wrong.
I only got the boot loader screen which says “Device state : Looked”
and when I go the “Recovery mode” I’ve got menu from LOS : apply update/factory reset / reboot system / etc.
I tried evry menu and nothing is working on well.
I obviously used the latest file proposed on LOS sie.
SO I’d like to come back yo /e/OS or Fairphone OS but impossible !!!
OK, since IMEI is written in the battery case of the phone and serial number written on lineageos bootloader on phone, I get now my unlock code … but … I just can’t do anything since I can’t access to any OS (I run only linux on my computers) !
Whatever OS you want to install … your bootloader is locked now, and you are able to get into fastboot mode. So first try to do the steps necessary in fastboot mode to unlock the bootloader. Any error messages with this?
Or you could try the Easy Installer and see whether you can skip the first steps until it tries to unlock the bootloader in fastboot mode (at least I suppose the Easy Installer doesn’t let the user do this manually).
daemon started successfully
error: device unauthorized.
This adb server’s $ADB_VENDOR_KEYS is not set
Try ‘adb kill-server’ if that seems wrong.
Otherwise check for a confirmation dialog on your device.
(So I did it again trying “adb kill-server” I’ve got same result)
