This doesn't seem to work. I do
Section II - Payload update
- Launch SafeA9LHInstaller from arm9loaderhax by holding (Down) during boot
- Press (Select) to update arm9loaderhax
- Power off your device
- Insert your SD card into your computer
- Delete the a9lh folder from the root of your SD card
- Delete down_safea9lhinstaller.bin from /luma/payloads/
- Reinsert your SD card into your device
After that It asks to press select on boot. This bring me back to the A9LH Update screen again, although the files are gone.
