Nintendo Handheld Console - New Nintendo 2DS XL - Black and Lime Green - Pre-installed with Mario Kart 7 (Nintendo 3DS)

Product Information

Update your RedNAND to the latest version using System Settings -> Other Settings -> System Update (if you have not already done so. ALWAYS make sure it says Emu in front of your firmware version.)

You'll want to basically remove anything not in that picture. You should only have either auto.3dsx or less.3dsx, depending on if you went ahead and setup lesshax. Both are shown in the image for reference only. While lesshax (you don't really need to use HxD if you decide to use this) is based on the 2.1 ninjhax base, with stuff removed to hopefully improve bootrate and stuff, as well as debug colors//text removed. lesshax should load the less.3dsx file on the root of your SD Card. Boot into the Homebrew Launcher. (If you have followed this guide, you should be auto-booting into the Homebrew Launcher via menuhax) Go to "EmuNAND Options", then "Miscellaneous...", then select the "Health & Safety Dump" option to dump Health & Safety to hs_emu.app (you can use Up and Down / Left and Right to change the name) Select the "Complete RedNAND setup" option. (If you plan on using a GW: Then do "Complete EmuNAND Setup")Boot into the Homebrew Launcher. (If you have followed this guide, you should be autobooting into the Homebrew Launcher via menuhax) For that problem with luma 5.4 (I think) I just put firmware.bin in luma folder and it boot up just fine Open HxD and navigate to and open the file that which starts with "ropbinpayload" (root:\menuhax\ropbin\) If you have followed this guide as well as the previous half of this optional part, with all my recommendations to the letter, then you should have a short 3 second window at boot time, where you see the CtrBootManager menu. So far, we have autoboot menuhax setup, as well as our Luma3DS configured correctly, and our RedNAND updated to the latest system version. But we don't have CIA Manager. So for this part, we'll be properly injecting FBI into our RedNAND for use as our initial .CIA manager.

You'll need to actually boot into SysNAND to see the theme. Either boot into SysNAND by holding L at boot time, or by launching Luma3DS from CtrBootManager while holding L. (This is assuming you followed my recommendations)Go through initial setup without linking your Nintendo Network ID, you want it to remain linked only to RedNAND to prevent issues. You'll probably still have a blank image display for menuhax, regardless of whether you used ihaveamac's version or the lesshax version. Both are easy to remove, and you can even customize it to however you want. Once you boot into SysNAND, you'll see your custom theme! Now get the hell out of SysNAND you psycho!
