My LG style won't go past LG screen and tried everything that lg & boost

I think that the LG company needs to know how the stylo 1 works and what a disappointment it is. Mine was only few months old and it won't go past the LG start screen I've tried everything under the sun it's frustrating cause I paid pretty Dollar for it brand new from Boost mobile. I'm single mom that's on a budget and was told LG was best out there. I want some answer please!
