Boot into the Homebrew Launcher. (If you have followed this guide, you should be autobooting into the Homebrew Launcher via menuhax)

In this example for Old3DS running 9.2.0-20 U, it'll be: "ropbinpayload_menuhax_USA12288_old3ds.bin"However, unlinking will format SysNAND, thankfully, setting up RedNAND has allowed us to create a copy of our SysNAND onto RedNAND. So everything is now on our RedNAND. 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 in RedNAND, install your GBA & DSiWare .cia files as you would normally, via FBI (Which should be by opening Health and Safety) The way we've setup our 3DS, we autoboot into the Homebrew Launcher via menuhax, but to get into our RedNAND, we must launch Luma3DS from the Homebrew Launcher. This isn't very ideal for some. So in this part, we'll be using CtrBootManager to autoboot directly into our CFW+RedNAND.

Like we said earlier, buying a 3DS now is a great choice. The past several years have seen so many great games come out no matter what genres you're into. You won't regret getting into Nintendo's best handheld to date. The patched sysNAND is only really useful for people who want to play GBA//DSiWare games. The part titled "~[Optional] Injecting FBI into SysNAND (For GBA//DSiWare Games)~" covers all the steps in regards to that and goes a bit more into detail on this. Copy the arm9loaderhax.bin file and copy the contents inside of the hax folder from the Luma3DS zip to the root of your SD card.Still, even aside from the 3D effects, the 3DS features a clamshell design – a design Nintendo has used regularly since the Game Boy Advance SP. This style of handheld protects the screen against scratches and makes the console itself more portable. Still, this design is somewhat of a double-edged sword considering the hinge that connects the console is prone to wearing down. Again, this is more of a problem with the original 3DS. Later models have improved upon the architecture of the original console, making it more durable. When you get to the CtrBootManager menu, we'll want to stop the autoboot, and hold L, and launch Luma3DS. With the ropbinpayload replaced with the one from the lesshax, it'll now boot less.3dsx at boot time.
