So I recently installed Lineage OS on my Fairphone 5 and (it was dumb) decided to lock the bootloader after the installation (the guide does not suggest to do so). As a consequence I can no longer boot into the operating system and my device is now locked. So I have access to fastboot and when I type fastboot flashing unlock I get an error.
Hi
No, you locked the bootloader on an unsigned OS. You have to put a service request to have your phone reset.
A bit more info on bootloader and bricking Guide to bootloader and bricking [2025]
Maybe begin here and they will tell you where to send the device (i think their partner is in France)
You need to be prepared to bear the cost of the procedure (30-50€)
Thanks. I had already gone through that but the issue is that none of the proposed diagnosis applies. Do you think I can just call? Also: I would like to thank you for being so responsive!
the improvement of the repair portal (so that it includes a bigger variety of issues) has been requested but I do not know how fast that might be implemented.
You could just generate an ordinary ticket here but that might take quite a long time to get a reply so I would suggest using the live chat tomorrow between 10-12 AM.
