For some reason it won't work with No Screen-Init a9lh payloads. This might be your problem, assuming you have the launcher.dat at the root of your SD.so I don't have a gateway yet but I'm getting one soon - but I put arm9loaderhax.bin (the one that gateway made) in /luma/payloads and renamed it to down_gatewait.bin and when I press down on boot I'm just getting a black screen
Shouldn't I be seeing some sort of gateway logo/menu?
