W600i debrand - please HELP

Hello to all, this is my first post here.
I've a W600i showing a strange issue: it can't receive SMS anymore. It continuously shows an error message telling to delete all messages from the phone to make room for other messages, though I did an hard reset and a firmware update through SE support site.
So, I'd like to flash the phone (and debrand it) trying to get rid of this problem.
Here is XS++ output:

Hold 'C' button on phone and connect phone NOW.
