I have SEK750i, today i turn off and turn back on the phone (http://howardforums.com/showthread.php?p=6295653#), nothing happen, except only white screen. I also try to use Update Service of SonyEcricsson for K750i website, but it seem doesn't reconize my phone through USB cable (http://howardforums.com/showthread.php?p=6295653#) (shipped with my phone).
Is my phone broken firmware or hardware trouble? How can i fixed it?
Everybody, please help me solve this problem. Thank you very much.

you need to flash gdfs with a ufs or cruzer software

you could use semc tool and flash all areas make sure u dont change the certificate or else it will have an error then unlock/repair using gdsf for k750. it works for me
