Help: Bricked HTC One M7 802w M7C_DUG

Hi everyone. I accidentally bricked my phone.

I really don't know much about these things.

Is there anyway I can install any OS?

What happened: I was trying to manually update OTA. I downloaded official OTA from phone, then I chose install later. I accessed the phones download folder and copied it to my computer. I extracted it and flashed the firmware in it through fastboot. and it didn't pushed through.

What I can only do is go to fastboot and to TWRP. I cannot flash anything. I cannot get S-OFF with firewater because it doesn't have an OS anymore.

I think I need to install a Lollipop ROM because the firmware is already on 7.19.1402.1. Is there anything I can do? or do you have a ROM that I can flash on it?

Thank you in advance.
