The name suggests it's an obvious transfer of the CTR part of the nand, i know that. But what are the specifics related to it? How much is actually transferred? How is it even possible? AFAIK you couldn't possibly share any part of another's 3ds NAND one with another because it would see it as invalid signature and thus, brick. Did people just managed to circumvent the protection and make it seem legit? edited out console's specifics adresses? How does it work and why does it make a9lh easier? This can't be used to revive a 3ds that wasn't MCU bricked, right? if not, why then? Thanks for all your answers. Couldn't really get the specifics on 3dbrew.
