Samsung s2 not working after update

view story

http://androidforums.com – Hi sorry if this is in the wrong place. I updated my S2 on orange network from android 2 to Ice Cream Sandwich using samsung kies and now i am having issues with it. I cannot make calls or send texts. When i try to make a call it tells me that calls are barred from this number. I tried going into the settings and unbarring but my passcode is not working, even after a factory reset. I also do not have any data coverage so cannot access the internet when away from my wifi. Any help with this would be greatly appreciated. Thanks. (General)
