I thought I was through this mess, but I guess not really. I followed the guide from Plailect and installed Armloaderhax on my blue New 3DS XL. So I've got Luma on the newest firmware launching as default and Gateway 3.7.1 on the latest firmware for .3ds and the cheat feature when I hold d-Pad down on my boot. When I insert my DSTWO (firmware 1.25) I can start the "Alex Rider" game and immediately get a black screen. I just flashes shortly from a "loading black" to a even darker black and I can't do anything but turn the console off. This happens for both of the CFWs. I've formatted the card with FAT32 again and updated again on 1.25. Sadly, that did not work. Somebody has an idea?
