I wish someone would touch my 3DS and come to my bedroom. My kids will only get the legit stuff.

You need one of a list of flashcarts to use that, not everyone can obtain an eligible cart. Also that's brick protection, it won't matter if they're just gonna sell it for parts anyway.

Reply I made earlier to the exact same question:

You can buy an ntrboot compatible card for like $4

Ntrboot bypasses booting from ctrnand, it boots a firm payload flashed directly on to the cartridge, you can completely remove the internal nand, and technically still boot a 3ds, using an emunand

Leftover feature from manufacturing and probably used to service and check your console for warranty, also could be used to detect cfw/remnants

Isn't it enough with this topic? I think everything that can be said has been said. Luma3DS pin is an easy topic and we're on page three already.

Having this thread going EOF-style isn't needed.
