Updating arm9loaderhax

The actual installation of arm9loaderhax itself consists of payload files installed into the firmware partitions on your device's NAND chip, which is soldered to the motherboard itself. These payloads are updated rarely and only really serve the purpose of launching arm9loaderhax.bin from the SD Card, which is, in our case, Luma3DS.

So far, arm9loaderhax itself has only been majorly updated once.

The old version of arm9loaderhax (sometimes referred to as "v1" because it was installed using SafeA9LHInstaller v1) was the latest version of Delebile's initial implementation.

The new version of arm9loaderhax (sometimes referred to as "v2" because it is installed using SafeA9LHInstaller v2 or FIRM81 because of its use of 8.1's firmware files to make room for larger payloads) is the latest version of AuroraWright's Fork of Delebile's initial implementation.

These steps will also update your various payloads and the AES key database.
