Default Boot loop

My LG e970 is stuck in a bootloop. i had the newest nightly of pac rom running but i wanted to take a crack at the new ubuntu for android, but that required a nexus 4. i tried installing the stock rom for the nexus 4 on my device but it got stuck in a boot loop. so i reinstalled the stock os but now it is stuck in a boot loop and i can't access my recovery. If anyone can help that would be much obliged.
