So, I finally got around to downgrading my 3DS to 2.1 to dump my otp.bin (and otp0x108.bin) and then I decided to be an idiot and restore my nand backup (9.1) from before all of this formatting and downgrading and what not instead of carrying on with Plailect's guide (since from what I could see, was about starting a fresh new sys/rednand and I wanted keep both my original sys/emunand). On the root of my SD Card I have otp.bin, otp0x108.bin, firm0.bin and firm1.bin (I dumped the firm.bin files with decrypt9 after restoring). Whenever I try to install a9lh with safea9lhinstaller through menuhax, I get the error "otp.bin doesn't exist and can't be dumped". I upgraded back because I was told that I could still install a9lh on 9.1 as long as I have my otp.bin handy. So, is there something I'm missing? Before anybody asks, my .bin files are named like otp.bin as they should, not otp.bin.bin or anything silly like that by accident.
