have a rooted lg optimus v & phone is stuck on the home page lock screen and will not unlock. On other occasions I was able to place a call from my home phone to cell and the screen would unlock. However phone is currently in airplane mode and calls now go to voice mail. Have tried to reboot several times, take out battery etc., but end up @ frozen screen, no service, airplane mode. I can go into recovery mode but obviously don't want to do a factory reset per the stick's. Suggestions?
