This should work on any version of GloDroid for the PinePhone but I've only tested it on 12.
You'll need:
Magisk 24.1
GloDroid 12
adb
fastboot
Steps:
1. adb root
2. adb shell
3. Backup boot.img:
dd if=/dev/block/mmcblk2p5 of=/sdcard/boot.img
4. Backup recovery_boot.img
dd if=/dev/block/mmcblk2p3 of=/sdcard/recovery_boot.img
5. Install Magisk 24.1
6. Patch both files in Magisk
7. Transfer both files onto computer
8. Boot into bootloader:
adb reboot...
