Default [Q] LG C800 bootloop

LG tries to factory reset and fails. says it can't mount /system
Tried many compinations I found online to get into recovery, no luck
Tried E-recovery (s/w upgrade) which it wont boot into, only continues bootloop
Tried a USB jig with only a faint option of hope, nothing.
ADB and Fastboot come up as access denied for any and all options.

Pretty sure it's bricked... figured I would ask if there are any other options
