Well, I'm helping a friend to get his o3ds updated so I installed the a9lh and everything was good until I tried to load a NDS game (flash cart and original). Previously it was able to play NDS games, it was on 4.5 so it was using the mset exploit, I updated it to 9.2 and did the downgrade to 2.1 to install the a9lh, however it was an automated installer so I didn't get the OTP.bin then I installed his previous emuNAND onto sysNAND. I tried to use the luma cfw downloaded from it's original github but it doesn't boot, neither saltfw does, I can only run the bin on that pack, I updated it with star updater and it also worked, I can also boot Hourglass9. Gateway bin also doesn't work Also tried to restore the original sysNAND (the one on 4.5) and still no NDS games. So I was wondering if I get the OTP to install another a9lh in order to use the files I got on my own 3ds that works perfectly, maybe that's the solution, however since a9lh is already installed, I can't boot sysNAND on 2.1, so what can I do? Thanks in advance.
