hey guys i just had this issue happen to me and was reading all of the comments. I have already fixed the problem. First like many are saying make sure antenna is connected correctly( use your thumb). Second Put an active sim card in the phone and let it sit. Wait for about 10-15mins. Then take the sim card out, and the phone should say NO SIM. After that insert the sim card wait a few seconds( might take minutes) then phone will start working. Again this method worked for me. Also the phone i was fixing had a code on it which I didn't know. So this method worked even without going into the phone. Thanks everyone. Hope this helps!!
