A day ago I left my phone at home while leaving for work. I have a 8 year old daughter who is very curiious with phones. She managed to get a lock code on the phone and she even changed the password. I asked her the password and the code she gave did not work at all she might have mistyped something. So bow the problem is I can’t get my phone to unlock. I tried whatever I could. Please someone help me with this lg vx8350 phone. Can this be avoided by doing a master reset?
