k800i cid52 white lcd
 

hi to all,
i have one of this model wich have many problems...
initially, the phone freezes a lot, and i flash the phone.. It become good, but after a few days, i get white lcd and freezes, or freeze itself, or reboot.
I flashed again with different version, and appened the same things as before..
Now i tried to flash again, but try to format memory card, but the problem is that i can't put it working!
i can flash, but when i try to boot the phone, it only appears white lcd and have to take off the battery to turn off the phone...
the gdfs is ok...
what can i do?:confused:
best regards and thanks in advance

try repair gdfs via testpoint, if the same result change the flash ic
