This may be wrong section, but i thought that if you can make a NAND backup with hardware mod, then maybe there could be a way to use the downgrade file on Gateway's website, and forge the NAND with the downgrade file, then restore it.
where do we forge it....the fires of hell?.....but in all seriousness, console unique nand encryption = no doing anything manually to the nand, the system needs to do the downgrading unless the user has their console unique xorpads.....and if they have those why dont they have a nand backup from when they could run the xorpad generator
.....tbf most people on 9.3+ did so by their own choice, there is just a handful of 9.4+ consoles that shipped that way and that's only n3DS consoles, anyone else only has themselves to blame for updating without checking if there was any "hacking news"
