Secure Startup LgV20 Please Help!!!

[Android Central Question]

I have secure startup on my phone that requires me to input my lock screen pattern on my device... my phone died. I charge it and turn it back on. I input my pattern, the same one I had since I bought the phone and it says its wrong. Im halfway through my attempts and to make matters worse, i tried to login to my sprint account to find a solution there and I have been locked out of that account too.. does anyone have any solutions for me other than resetting my phone??
