Ok this is my first post so please bear with me. I have a rooted Evo with a very wierd 3G connection problem. FIrst a little background on the phone. I have had the phone for over a year now and decided to root it. Everything was fine until one day I dropped the phone one too many times and the display stopped working. Since I don't have insurance or am not eligable for an upgrade, I decided to try the DIY method. I ordered a new LCD screen and digitizer from Amazon and installed it. Everything worked great. Now it was time to call Sprint and deactivate the temporary phone I was using and reactivate my old HTC Evo. In order to do this I had to install a ROM with Sense in order to recognize the Sprint codes I had to enter to activate the phone. I did this and activated my phone. This is when the problem comes in to play. After activating my phone I now have a "looping" 3G connection, meaning 3G will connect the send and recieve arrows will blink and then the signal will drop and the 3G signal goes blank. It will do this over and over without a solid connection. I have reinstalled my profiles/PRL multiple times and even made sure and flashed an update for the radios. I am thinking this might be a hardware issure but I can't find ANYTHING about the physical loaction of the 3G antenna on the motherboard or any sort of troubleshooting proceedures for this. If anyone has any help it woudl be GREATLY appreciated! I am having trouble with streaming video or searching on the web as a result of this issue. My phone calls and texting does not seem to be affected.
