You are welcome,you said that it happened after flashing(lost 900mhz network)so i still beleive it can be solved with good backup.Maybe uploaded backup is ok too but i am not shure.If i will get C905 for repair soon i will make backup and send you pm then we will try again.I hope you unlocked/flashed some other phones.Please post here identify log from Omnius after SEUS update.
