I messed up two things but it was nothing that compromised the console

I have unbricked systems using the plaintext method,, and I have always tried to discourage end users from trying to hardmodding themselves (too many complete screw up for my liking), it would be better for him to send it off to someone else and maybe they would be able to unbrick for him, but yeah your right someone who can't follow simple instructions would probably screw up even worse than they already have

The problem is OP doesn't have a Nand backup created by Decrypt9 since he use safehax to boot SafeA9LHinstaller, skip to A9LH installing state with his O3DS OTP.

With the known plaintext attack, he doesn't need a NAND backup. Maybe one of the hardmodders can do it for him. @vb_encryption_vb ?

Other than the hardmod, I don't even know where to begin with this. I'm not sure how @gamesquest1 managed to unbrick. I assume dumped and patched NAND manually with hex?

So the way to fix this by plaintext attack or somthing only avaliable by him then?
I think this plaintext method won't be famous since less people know it.

yeah I kow this, all he would need to revert back to stock would be the plaintext of one of the firm partitions, AFAIK this should be the firm0.bin in the a9lh folder

see the brick I fixed was a failed 2.1 ctrtransfer that froze on writing nfirm, so knowing the system was on 9.2 n3ds fw I was able to make a xorpad for their firm section, then use that xorpad to inject the 2.1 firm, once done the system started up, but was stuck on 2.1 as they had no Nand backup (this was before Decrypt9 was changed to allow n3ds ctrtransfers from 2.1) so anyone doing it now on a n3ds would have an easier time

well it's less known/used because if it weren't for people being stupid it wouldn't be needed

and we'll the concept is the same thing used to perform the hard mod/dsiware downgrades
