Why my phone vibera and restart and no screen? my phone is sony k850i

Download SEUS (SonyEricsson Update Service) and install it on your pc. when installed run the program but DON'T CONNECT the phone yet.
Remove battery from K850 for 2 minutes and then reinsert. Hold down C button and while holding plug in USB cable. Release C button ONLY when the program ask you to do so. Then follow on screen instruction.

My K660i keeps turning itself off and doesnt turn on again for long periods of time . taking the batery out and back in again does not change the situation, you cant do anything with it for about 15-20...

A sw update should solve the problem. Sonyericsson offers that on their homepage. Go to and go to the support page where you will find a client and instructions on how to update the sw.

Sony Ericsson K850i Display Problems

hi. first,. SORRY for my bad typing...i know how to fix it, had the same problem earlier this year with the blacklight gone after a bad update, but you can fix it easly yourself without turn it in.

you can goto and download the update and that SHOULD to the trick..

that is a norwegian link. but if you click on the flink that says " Last ned Nå"  you will download the program that will install the new update, you can instal the program in english, so that  is just peace of cake from there.. 

Hope that will fix it :)
