Default [Q] Nexus 5 most likely hardbricked what do I do? Please help

I think my nexus 5 is hardbricked doing a paanodandroid ota update
This happened on latest paranoid android + latest franco kernel + TWRP

I wanted to update pa gapps (first 2 downloads md5 checksum failed, third time it worked) and when the phone booted afterwards, systemui failed and I couldn't do anything. I Thought this wasn't a big problem since the phone managed to boot. I long pressed the power button to shut it down so I could boot into recovery to restore my backup I had recently made. When I tried to boot into recovery it wouldn't do anything. Not boot into recovery and not into fastboot. How is this even possible by simply flashing gapps?

What should I do?
I've tried all the button combinations for more than 15 seconds.
