Samsung galaxy s2 water damage - it's turning on but can't connect with the carrier
I have a samsung galaxy s2 phone that had water damage. It's dried but I keep getting the message that can't connect with T Mobile server after I turned on. I took it to T Mobile and they told me that they don't have any problem with the server and the problem is with the phone.
I took it to the repair shop and they opened the back cover, checked the phone, it's all dry but they can't fixed it and they don't know why the phone can not connect with the server. Is there anything that I can do to fix this problem? Please help. Miranda.
