Why is my LG Optimus L70 stuck on a loop?

[AC Question]

When I try to turn on my phone, it makes it to the "metroPCS" logo, stays on the logo for about 10 seconds, then reloads the logo again. It will not turn all the way on. I've even tried taking the battery out several times, and then waiting about an hour before putting it back in and trying to turn it on again. Somewhere I heard to hold the power button, home button, and up volume button in order to do a soft reset. That also didn't work. Any suggestions?

Welcome to Android Central! The firmware might have become corrupted, or there could be a hardware malfunction. There may not be much you can do besides trying a hardware reset, which will wipe the phone.
