11.1 Downgrade issues

A friend gave me an o3DS to downgrade. It's running 11.1 and I did a transfer with Fieldrunners with the public.sav. The exploit looks like it starts up fine, but when I run the Downgrade option, it reaches 8192/8192 and says:

Done!
reErr:0 wrErr:0

I made sure I'm using the o3DS 11.1 version of the dgTool and firmware files. I also googled around and didn't find anything helpful. I also tried OoTHax just to make sure. I couldn't get it to work, trying both the 11.1 payload and 10.4 payload. Is there anything I'm missing or is he just screwed?

 

Oh, I figured those were error codes. I have the boot.3dsx file in the root, so it should at least boot into the Homebrew Launcher. I've tried both the 10.4 payload and 11.1 payload. Whenever I try to execute it, it just crashes and the 3DS says it has to restart.

 

I've been using the payload for 10.4.0-29U on o3DS, which this 3DS is an old phat or whatever they're called.

EDIT: I figured it out. I'm just an idiot, I didn't realize they way to activate the exploit changed. I kept trying to launch it with the Ocarina while it requires the A button to be pressed now.
