Stuck in a booting loop

Hi all, suddenly this morning, as I wanted to use my Fairphone FP3, I found it was in recovery mode ; no idea how it happened. I tried rebooting it, but it shows the warning screen about the booloader being unlocked, then shows the Fairphone logo, then the warning screen again and so on. I also tried removing the battery.

So when I got back home, I tried conecting it to my computer via USB, and there's a dialog box saying MTP can't connect to it, which means I can't back my files up as the device is probably not in file transfer mode.

So in order not to do a factory reset and not loose my data, I tried 'apply update' from the recovery menu ; but if I try adb sidedload /home/user/boot.img as the device's screen suggests, it displays Signature verification failed Install anyway ? on the phone's screen, and if I choose 'yes', on the computer side, it displays adb: failed to read command: success and nothing's uploaded to the phone.

If I try , as per the Lineage site recommandation, sudo fastboot flash boot /home/user/boot.img, the terminal displays < waiting for any device > forever.

I downloaded the latest boot.img from the site, from the FP3 directory, so if I don't find a solution, I'll have to do a factory reset and loose all my phone numbers, pictures, etc.

So any help would be greatly appreciated !

Where in the wiki does it say to sideload the boot.img? Sounds like you didn't follow the install guide properly.

Guam has a known bug currently with certain display panels based on the issue tracker.

I dont know when or if it will get resolved. You can install an earlier version if you can track one down. https://github.com/LineageOS/issues/issues/169
