Hacking Trying to fix eshop error 022-2634

I recently bought a 3DS from a friend and when I format my emuNAND with tinyformat and inject the emuNAND back to the SD Card it doesn't work.

I'm using my own NNID, i'm not sure I have to use his, but if this is the problem is there a way of removing his NNID from both my sysNAND and emuNAND completely?

-edit-
after I restore my emuNAND and put SD card back in his NNID shows up and not mine

1. Backup your emunand using emuNANDtool and copy the Nintendo 3DS folder on your SD
2. Format emuNAND on System Settings
3. Complete the initial setup and link your NNID
4. Restore your emuNAND (using the emuNANDtool) and your Nintendo 3DS folder

If you don't have neither NNID's PW nor the e-mail access for NNID registry, then you had better return the 3DS back to your friend and get back the money.

Wait... Are you using emunand from a different 3ds? I would start by using tiny format on sysnand and create new emunand from sysnand.
