HTC ONE M8 (BRICKED) Really need help

A

AC Question

Hello, i'm Joshua. I somehow bricked my HTC ONE M8 (It was rooted). I'm from the UK so I'm not with Verizon or Sprint, my carrier is o2 (If that helps) I really badly need help! TWRP is installed and I tapped something with in the TRWP settings and it just bricked my device.

I can still access the White screen that shows the "Fastboot... Recovery" etc page.

I'm still kinda new to this stuff, so term like "OTA" I don't fully understand. I freaking out!
On the "Fastboot" etc page it shows...
