Hey everyone, I have a k850i and I wanted to change the language to Greek(EL-Generic Adriatic and also S-E-Europe) using the wotan client2. It finds the phone and starts downloading and everything seems fine until the actual burning process to the phone comes up with an error box saying "invalid account" and then "Can't retrieve key (error-1)" Has anyone else had this problem? It's a Vodafone uk mobile and I unlocked it using aerix site. Any help please...
