@bami: How to apply the patched boot image
- Make sure your FP3 is updated to the current patch level, (.0022) that it has the developer option enabled, that the boot loader is unlocked and that the current Magisk app is installed.
- Make sure your PC has the Android developer tools adb and fastboot installed.
- Download the patched boot image from https://github.com/topjohnwu/Magisk/files/11646684/FP3-8901.4.A.0022.0-boot_magisk_patched_skip_initramfs.img.zip (from the link provided in “Bootloop upon fastboot installation with FP3-8901.4.A.0021.0-gms-0b368514-user” above) and unzip it.
- Reboot your FP to bootloader mode with “adb reboot bootloader”
- Boot the downloaded image with “fastboot boot FP3-8901.4.A.0022.0-boot_magisk_patched_skip_initramfs.img” and make sure the patched image works for you.
- If it does then reboot again to fastboot mode as in step 4. and then install the patched image to the boot partitions of your FP3 with “fastboot flash boot_a FP3-8901.4.A.0022.0-boot_magisk_patched_skip_initramfs.img” and “fastboot flash boot_b FP3-8901.4.A.0022.0-boot_magisk_patched_skip_initramfs.img”
- Reboot (“fastboot reboot”) and enjoy
Note: If you want to apply any future releases to your FP3 you will have to revert to the unpatched boot image, so I strongly recommend that you keep an original boot image as contained in https://fairphone-android-builds.ams3.digitaloceanspaces.com/FP3/FP3-8901.4.A.0022.0-gms-5bdac72d-user-fastbootimage.zip handy. To flash the original boot repeat the above step 6 with the boot.img contained in the images directory of the zip.
