Need help for flashing W550i

[JeNeI]

For few days my phone was having some problem Searching for network. When restarted it took longer than usuall to display the Network operator's name.

It has stopped working after I restarted it recently.:(
When the phone starts after a beep sound a message is displayed-
"Configuration error. Please contact your network operator or service centre."

I have tried updating it thropugh SEUS but it didn't help.
So i want to try reflashing it's Firmware.
I am new to this stuff, so please tell me the programs and how to do it.:confused:

hi.first of all search the newest FS and MAIN (firmware) download a program called XS++ put the FS where ask for it and also for MAIN.Note that you needf at least 75% battery charge.When you finish your fone will be back again.Good luck.
