Newbie to using Far but maybe I picked the wrong phone to try and flash with it. Seems I need a Main and FS for W850i Cid53 it has at the moment R1KG001 on there. AT the moment the phone starts up to the sony logo flashes white screen and then goes to Please wait and then nothing. Check through the downloads no W850i CID53 available, saw on the internet CID53 for W850i through setool box downloads but not a member and don't know how to become a member and I think you can only use it if you got Setool box. Anyone help me with my problem.
