Default [Q]CWM boot loop

Just got the ATT gpro e980, and installed freegee CWM, downloaded a stock rom with extras, made a backup of current stock rom then wiped everything, flashed the zip and then it said error loki-fying. Tried restoring backup, had no errors, tried rebooting but always ends up back at CWM. Tried booting to bootloader, goes to CWM. Only way to fix this is using LGFlashtool? Any advice appreciated.
