I went to Davinci to rebrand my c905 to O2 firmware that supported all the features in SE's latest firmware update. After a few days using this, I decided to use A2 and the CDA generator to change to the generic firmware. O2 was solid but I didn't like the branding icons on the main menu. I changed the CDA and put T-mobile-UK and it was even worse, but cannot go back even after trying many of the CDAs in the database. SE keeps informing that I have the latest update. My only conclusion is that I have updated across all the regions that are available and I can only downgrade to resolve this.

Any suggestions?
