Hi, I really need help for my situation. I got my S4, I can install recovery, I can install custom rom (Cyanogemod..) but now I want to restore to TouchWiz stock rom, because I need that to unlock my phone. Everytime, every rom I flash with Odin failed. I try 2 days and now I feel hopeless. I try every stock rom, MJA, MDC, NAE (4.4.2). I got know void warranty 0x1, I don't know if this is a problem for restore. Can someone help me ?
