Hi guies!!

My K800 suddenly shut down when i started a game, and had a flashing red light on the IR. After searching on the web i found that it was the problem of the erom. I then followed instruction saying i should use the wotanclient to fix the erom. after that, everything was fine, but only for one week, because now the problem is back but when i do the process wotan says that the upgrading header failed.!!
I read that since wotan upgraded to phone to CID 53 it's quite hard to find a way!is it true?
What can I do? i'm so desperate. here are some info of my phone i checked with xs++:
