I have been having problems with my LG Chocolate Touch phone. The screen has been pushing buttons by itself without anyone touching it. It happens right on the # "7" on my dial pad or on the "shift" button when I'm texting. I tried re-calibrating the screen but this did not help at all. I also tried shutting the phone off and removing the battery which also did not help. So I decided to try and restore my phone. I did it and then turned my phone back on, but it is locked now and I can't figure out what the lock code is. I tried the last 4 digits of my number and also the last 4 digits of the MEID and neither of them will work. so now I'm stuck with a phone that is useless until I get it unlocked. How can I unlock it?
