I just flashed my old k310 to w200. I read flashing instructions from this site
http://bandung-flasher.net/forum/sony-ericsson-software-repair-area/6702-tutorial-convert-k310-w200.html
I done everything it says but when I turn on my phone displays this message:

Configuration error.
Please contact
your network operator
or service centre.


I tried 4 times

Please don't recommend anything from topsony.com


Sorry for my english I'm from Bosnia and Herzegowina

You just forget to customize your phone (CDA)

How to custumize phone

i will look for the corect way and back to you

Just flash customization file (zip) specified for your region and language. (F.e. for Russia this file named as
K310 GEN_CDA102576_8_RUSSIA.zip)

after i convert my k310 to w200,i can convert again-when i want-the w200 to k310?
pls tell me!

yea you forgot the custpack.
most people will just flash the firmware and the FS and forget about the custpack.
and you can convert back from w200 to k310 again.
flashing of phones void your warranty.
