Hi. I bought a used 3DS Xl (edition with Mario Kart inside) with already installed Gateway. The console came with the red and blue card as well. When testing, it boots emunand perfectly with DS Profile. SysNAND 4.3U and Emunand was outdated too, GW3D 4.3U. Before buying, I asked the seller for a video showing the red card in action and in the video it worked fine, but only with 1 ROM inside the microSD. Since nowadays Gateway can load multiple ROMs, I started updating my red card. Used latest gateway ulltra (3.4) via blue card to install the exploit on 3ds profile. After I did that when selected DS Profile with L pressed, the gateway menu booted. Then I backuped my SysNand and formated emunand. The problem was after that. When trying to boot into gateway mode it shows: "no gateway 3ds card found!". I tried to delete exploit (by loading any nds rom via blue card) and reinstalled it with 2.7 Omega and followed all the steps again with an olderlaunch.dat --> same error. When trying to force update, it goes ~5% and starts looping only to give me Error 00000006. Now I really don't know what to do. My SD card is a micro SD 4GB Sandisk with adapter and the microSD cards on blue and red card are also 4GB Sandisk. Red card's microSD is ExFAT and the others FAT32. Diagnostic says everything is ok but i cannot enter gateway mode. Tried also using gateway's online metod to launch the Launcher.dat and it gives me the same problem. Any ideia how to fix it?
