K800 goes off with a white screen

[riders4sia]

Hi, I've just unlocked my k800 with D-Ultimate Unlocker, only the infrared light flashing, now the phone is turned, but there is a problem, when I try to open the phone book the phone goes off with a white screen and then turns on by itself, which may be the problem? What can I do? Thanks.

well your problem is with the GDFS (corrupted GDFS) but you may try full flashing before repairing GDFS with D-Ultimate Unlocker

Hi, which program I must use to do this? Could be a firmware problem?
