trouble starting complete fresh with xbmc

Hi,

firstly thank you to anyone who can help.

I am new to xbmc. All I want to do is remove xmbc and all the add ons/repos and everything associated with xbmc, just so I can start again, as my some addons have stopped working. It stopped working properly after trying to install new repos (after following a vid on YT)

so...

I followed these commands:-

apt-get remove org.xbmc.xbmc-atv2
apt-get autoremove
rm -Rf /private/var/mobile/Library/Preferences/XBMC
rm -Rf /private/var/stash/Applications/XBMC.frappliance

but when I put xbmc back on and I run it, it still has all the repos installed and some crazy russian writing that wasnt on there before I messed with it.

All I want to do is remove every last trace of xbmc and everything associated with it from the ATV2 so I can start a fresh and get it working to how it was before, (ATV software 5.0.2 and os build 5.1.1) the version of xbmc was 11 when I tried to install super repo, but now updated to the 12.

Would appreciate some major help here.

Thank you very much in advance.
