It didn't work. It gives the same kind of file as Decrypt9WIP-20170115-230509 version. It says something like update error log. It's a bit broken up, but I can sort of make it out. It says rand seed (random seed I assume), native log, and it goes on... local friend code, secure info, etc.
I tried it on 2 systems. Both with same results. When I use Decrypt9WIP-20161113-135126, it gives me the properly processed enctitlekey.bin.
I'm using N3DS 11.3.0-36U with Luma3DS nightly (92ec2af5) with a9lh (Aurora's
4fc9ad8 from 20161017 with data input v4). It's just on SD, not on CTRNAND. Could that be an issue? I know you updated it to work with CTRNAND.
I assume the date of the dumps, including NAND, is always wrong because a9lh doesn't use the clock and it defaults to some date? Would it be possible to use the system date? I assume it's like a PC where it's set in the BIOS. It's set somewhere. Not sure if it's easy to access on a9lh.
