E398 White Screen After Flash

[f1nch]

Hey Guys!

I bought my second E398 and want to flash it. E398 to Rokr flash worked fine.
But when i flashed a MP somehow my PC or the Mobile crashed while i flashed it. (i used F&B 3)
Now everything is white Screen.

The mobile starts i think coz i can hear the menu sound and stuff. <-- But only white Screen
I also cant start Bootloader, also white screen. Force Bootloader methods also dont work.

When i connect the Mobile to PC it get connected. But when any Tool changes to flashmode (means to BL) then Mobile/Tool crashes.

F&B 3 <-Crashes
RamlDR <-Crashes when changing to flash mode
F&B 2.5 <-Crashes
Yesterday i somehow get it white screen away with the Motorola Repair Studio.
But after i did Backup again everything white.

I dont know what to do guys, hopefully anyone of u can help me.
