After debranding of c905 I can´t use Flash menus

Hey guys.

I have a Sony ericsson c905 purchased by Sonofon in Denmark without a subscription.

There was then a new firmware which allowed you could have a chat feature announcements and youtube and smile shutter feature tracker.

Since I had updated to the new firmware, I had only smile shutter and tracker feature.

I tried so to debrande mobile phone for 1214-0329 NORDIC Sonofon Denmark from 1209-4769 NORDIC GENERIC NORDIC mobile phone which had the region before.

But the new region is that I have had chat and Wayfinder has been updated.
But the region has done that I no longer can use flash menus, what do I do now and how do I find a region code so that I can get chat back and can use flash menus? hope can help me.
