So i installed custom recovery with auto rec and it was glitchty so i restored the phone with twrp. Upon reboot it told me if i wanted to install SU and i clicked yes so it began to reboot. now its stuck on the lg logo with the led flashing blue and green. when i try to get to download mode shows firmware update on the screen but stays on 0% .. it is not recognized by the computer however i hear the sound as if it registers but does no show up as a driver under my computer.. if i try to restart the phone it just brings the lg screen back up like a reset... i can get it completely off if I hold the power button even after the lg logo comes up
