I've never had problems with ROMs on here either. I used TB 1, 2, 2.1 and 3. Had no big problems with those either. Just cant get TB4 to connect to wifi or data. Maybe it's a bad download. Can I get an MD5 marxman?
I've never had a problem flashing this rom or any other rom on here cm10 can be a little buggy but that's with all ports of cm10 not just this one
