It's a samsung Galaxy S2 GT-i9100. I had ICS 4.0.3 on it before, but wasn't offcial, I had already rooted it succesfully before. Should I be trying to now flash an original kernel to it, or a stock rom? If so, please could you give me a link for which one to use. I am with T-MOBILE UK. Hope that helps. Can't believe I forgot to enable USB debugging. I hope I can get it working again.
