Default HELP! LG G2 (sprint) [450] fastboot mode started [500] udc_start

Well I have a problem, after numerous attempts trying to flash a recovery onto my g2 I finally managed to have it stuck fastboot more started. When I boot the device the LG logo quickly flashed and it just stays at [450] fastboot mode started [500] udc_start. Before I was able to just hold the power button till the device restarted and it would boot normally. I'm really in some deep doodoo here and could use some help getting out. I'm able to boot into download mode by holding the volume up + power button at the same time if that could help me in some way. Please help me save my phone!
