Hacking otp.bin "doesn't exist" but is on the sd card!?

[Bubsy Bobcat]

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.

What is the size of your OTP.bin?

Are the files supposed to be on the root? I thought they were in a folder on the root iirc

otp.bin is 256 bytes
otp0x108.bin is 264 bytes

You're correct, there's supposed to be in the a9lh folder..iirc. Not on the root of the SD card. I've had this same issue.

The files are supposed to be in /a9lh/

OTP.bin needs to be in the a9lh folder. I had the same problem, I guessed to move it there and that worked :-)

Oh, so @Bubsy Bobcat
try putting it in the a9lh folder in the root of your sd card.

Ahh, right. I thought it would be something like that. I'll do that right now.

Right, I've done that but now I get another error: "firm0.bin doesn't exist or has a wrong size". (It is 4,096kb) I have FIRM0 and FIRM1 copied to three different places on my SD card as well since I'm not sure where I was supposed to stick them (root of the sd, decrypt9 and a9lh). Anyone know where they're actually supposed to go?

4096KB definitely wrong size and wrong files. Make sure your firms are from here
"data_input_v2.zip" on plailects guide.
https://github.com/Plailect/Guide/wiki/Part-5-(arm9loaderhax)
And they go here -> sdmc://a9lh/<here>

Make sure every file that you use is from that guide except otp.bin of course.

Ooooh riiight! Thanks much, hopefully I won't be an idiot anymore (or at least for a week, hopefully) when it comes to these sort of things.
