Hi, I had the same problem with my LG Ally Android. I had the visual pattern password - my daughter was messing with it while I was putting our baby to sleep and locked my phone - it also said too many attemps and would display please sign in with your google (gmail) account. I would enter in my u/n and p/w and it would not seem like it was doing anything but would say it was invalid which I knew was incorrect. I called verizon tech support who said it is impossible to reset the phone to the factory settings without reflashing in the store.. WRONG.
Do this:
I have good news if you haven't figured this out already... Forget tech support - I figured it out without having to go in.. Now you will lose all your saved apps and data. If you have a sd card I would take it out and put another one in just incase. I dont know if it will delete all your pictures by doing this. It is a FULL system restart so it will go back to exactly how your phone was when you bought it.
Any ways, this should work for you...
For those who can’t access the phone’s setting menu, you can hard reset your LG Ally by:
1. Turn the power off.
2. Press and hold: Home Key + Power Key + Up Volume Key.
3. Turn the power on, while keeping the three keys pressed.
4. When the LG logo is shown, release the keys.
You will lose all your downloaded applications, contacts, ect but it is better than going into the store to have them reflash it (would still lose everything) or sending your phone in to repair it. I hope this helps somebody.
God bless,
