Hello, I've been using samsung galaxy s 2 for almost two months now. And I have done many updates and none of them gave me this issue. Can someone help? I'm going to tell you all the steps I've done below. I was using 2.3.6 on my phone and everything was working smoothly. Then I came across to ICS frimware from SamMobile, K8. I installed it to my phone via Odin (I've always used that for updating) It's been installed just fine and my phone booted into brand new ICS and I liked it so much. I quickly connected to wifi and set up my google account and etc. Then I disconnected wifi to use my data plan. The network signal was on and it seemed fully connected to network but when I pulled down the notification bar it said EMERGENCY CALLS ONLY. I tried everything but none of them seemed to work so I installed the old rom I had. It had been working good. But after installing it to my phone I got the same error.. Can someone help me with this problem?
