Really Bricked LG G2

I have a verizon LG G2. I had cyanogenmod nightly from 8-14-15 installed with CWM Touch 6.0.4.4. I installed Cloudy G2 v3.3 with that recovery, after wiping system/data/cache/dalvik and the install went fine. I tapped to reboot and the screen went off and will not turn on again. No download mode, No QHSUSB mode (as far as I can tell), no lg logo, not even a screen backlight. The only sign of life is a faint high pitched ring coming from the motherboard. I'm thinking I may have unknowingly had a Lollipop bootloader when I was supposed to have a KK bootloader when installing? Would that cause this problem?
Thanks for your Help!
