Well, was not as easy as I hoped getting back to my ICS build. Nandroid restore kept giving me this error on all my backups.
"Error while restoring /data!"
So I had to go back to stock 4.0.4, reroot, and then restore my backups. PITA but could of been worse.
Anyone else having problems with restore, just follow this guide....
