W850 Flashing White Screen After Full Flash

It all started when my W850 failed to restore the GDFS. After that when I tried to connect to XS it said GDFS name does not match IMEI name. I then gave it to a friend who has Cruiser box and now the warning doesn't come but still flashing white screen.

Here is my log in XS before full flash:

What shall I do???

try to reflash using SETOOL, worked for me

Try SeTool2Lite.

Flash your phone and How to apply or remove patch using SETool 2 Lite - Top Sony Forums

I flashed with setool but same result. But the warning gdfs K700 came back. But when i restored gdfs it went back to normal.

What shall i do???

hey it works thx

you said you wanted to restore gdfs
so it means that you have a copy of your gdfs is that correct?
if so, try to flash back that copy and everything should go fine

I have tried that but still same problem

your gdfs is damaged, try this How to Repair a db2020 GDFS - Top Sony Forums

borrow your friends cruiser cable and try to repair the gdfs following the guide cruiser cable will give better results than the dcu-60.

i really doubt that will work
even with foll setool there are people that did not succeded in doing that
without security units, phone is as dead as a rock

When i use that method i get exactly the same proble. i guess that the security units are damged. isn't there a way to recover the security units?

Not really.
