Hi I upgraded mine A9LH O3DS XL from ARN 4.1 to Luma3DS 5.4 using this upgrade guide here:
https://github.com/AuroraWright/Lum...ade#upgrading-from-arn-43-or-older-to-luma3ds
After upgrading, I did the initial setup, and check marked "Force A9LH detectection" and "SHow current NAND in System Settings".
All works as intended (1st emuNAND boots by default, sysNAND boots by holding L, 2nd emuNAND boots by holding B)
But none of the payloads works (just blank screen with backlight on), I have named them all in the newer format and I guess I no more have to hold L key with the payload key anymore.
Kindly let me know what went wrong, why none of the payloads work. I have start_d9.bin (Decrypt9), x_emund9.bin (EmuNAND9), y_uncart.bin (UnCart) in the luma/payloads folder.
