After trying various procedures fix this, i finally had to go for factory reset but after factory reset, when i restarted my phone the setup wizard of cyanogen appeared and when i select language and press next it once again shows the same settings has stopped dialog box.My phone has become useless as i cannot get past that setup.....Please help ,
