Built-in NVRAM installer on Old 3DS

Hello guys,

I think I screwed up something on my nintendo 3ds by installing the build-in NVRAM on old 3ds

I did that because I wanted to do the exploit using the DS Profile instead of the browser, since my system in on 9.2

Now I can't start emunand, I have already restored the nand but still can't do that ...

It says that I need to insert the gateway in the slot but the gateway is already in there ...

Please help ...

Sorry about my english ...
