ok i rooted my phone a few days ago and flashed sky ice cream. i backed up the stock rom (2.3.5). i tried restoring the stock rom and its says the md5 file is missing. so i decided to unroot my phone and restore it back to stock rom using odin and sgh-i727-uck j2-k0nane.tar. the unrooting was successful however my phone is still using the sky ice cream rom. is there any way i can get back to stock rom? if anyone knows anything about this please let me know. it would be much appreciated.
