My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
What is the model of your phone please?
You can reply to me here by typing in the box below please.
yes, that sounds like the firmware cashed. We can most likely get it working again with a factory restore.
Give me a moment and I will post the steps for you to follow.
did that work?
okay, sounds good so far. Did you have a google account connected to the LG?
okay, great. You can sign in with that email and password, then anything that was set to back up will be restored.
yes, actually it is fairly common especially if the phones aren't powered off regularly.
yes, it should be getting back to the initial set up screen.
okay, try charging it for a few minutes, then if hasnt restored try the restore process again.
okay, if the restore doesn't work then that will indicate a failure with the hardware, usually the main board.
no, unfortunately that would cost more than a replacement phone.
no. unfortunately the restore is the only option. Sorry.
