K800 sleep mode white screen

[vidmag]

Hi

I flashed my K800i with appropriate firmware etc (R1CB001) using SETOOL. All seemed to have worked except I now have a white screen for Sleepmode. Not really fussed about colour except that it drains the battery. Used to get 7 days use without rechrge now don't even get a full 24 hours.

I also have the error in menu message on startup, but that can be clicked by and seems to have no other effect. I have tried changing replacing menu as suggested in the forums but that does not seem to have changed this.

Anyone tell me how to turn it back to black. (Simple steps please for a simple mind)

Thanks
:D
