HELP??? K800i freezes

[andd2007]

Hallo,
I need help to repair my K800i. The K800i freezes, when I turn it on everything works but it freezes 30seconds later and you can do nothing about it only battary remove turns the phone off. I tried many things, like flashing main+fs +custom: flashing with k810i and so on. and all is the same the phone freezes, but when after turning the phone on i play music it doesn't freez and when i turn the music off the phone freezes again. And there is one more situation where it doesn't freeze , its when i connect the phone to the computer.

Please help what can I do with the phone?

u can flash the erom with xs++ guide here Upgrading or repairing the EROM (FOTA) in phones CID 49 or CID 51 with Phone XS - Top Sony Forums,
after flashing the erom u will need to do a full flash main fs & custpack

[safd]

You havent to reflash the main etc. when u only upgrade the erom .but i think that a erom update cant help u ( but please try it out anyway)
