Dingh is right. After flashing to a different modell or even a different FW version (as long as you flash a new FS either) the phone gets unbranded. Actually it is the best way to unbrand the phone.

But there can be some minor problems when using customized menus on brand phones. I had my cid49 k750 branded with O2 UK and after uploading new menu, some icons stayed the same as before, some dissapeared completely and some looked weird. It can happen... After I debranded, everything was fine. So I think mysecell60's problem could be related to the branding. Maybe not the only problem (missing layout or menu file is highly probable) but the branding can make it worse...
