Fairphone 4 Update & Root¶

To update a rooted Fairphone:

Try this first:

1. In Magisk press 🗑️ Uninstall Magisk → Restore Images
2. Install OTA-update and let it perform a full reboot, wait for the update to finish after the reboot
3. Boot into bootloader with adb reboot bootloader
4. Use any Magisk patched boot.img you have lying around and fastboot boot from it. It doesn’t matter which boot.img you use, you just won’t get usable wifi (and some other problems) with the older ones, but since we only need to install Magisk that doesn’t really matter.
5. Choose Direct Install in Magisk as usual, reboot and have fun

Try this as a second chance as both versions preserve your data.

If none of those work, try these instructions:

Hint: Only restore after the procedure, the device will be wiped again, if you relock the bootloader.

1. Make your backups, your device will probably be wiped
2. Download desired update and install it. The bootloader has to be unlocked if it was (re)locked before. If fastboot doesn’t find your device, try another USB port (direct mainboard ports worked best for me) and try another cable.
3. Root via this instruction (Waybackmachine) rooten.
4. Optional and NOT recommended: Relock critical if you want, but DO NOT RELOCK THE BOOTLOADER, as it will most likely brick the phone.
5. If you want to relock the bootloader, run fastboot flashing get_unlock_ability before. You should only relock, if it returns 1.
