[Q] Stuck in bootloop, can't connect to adb topic

I tried installing CM12 and when I restarted I got stuck in a bootloop. It just stays on the LG logo screen for a while until the kernal crashes. I can enter Dload mode and fastboot and I see my computer installing the drivers but adb devices says nothing is connected. I tried entering recovery but the phone just vibrates, restarts, and goes back to the LG logo. Is it fixable or do I have to send it in for repairs?
