[Q] Recovery Issues... No Backup

I Recently Rooted And S-off'd my HTC One M8 (Sprint)

No problems there.

I was being a dumb ass and installed a new radio frequency without backing mine up..

This caused my phone to start a boot loop, so I reset it.



I have no OS so I can't turn on debugging

When I attempt to sideload or push a zip ADB tells me it can't find my device.

Do I need to use RUU?

I can boot into recovery or bootloader.

I'm looking to go back to stock and lock my bootloader.

Any help is welcome.

I'll update if I can get anything working here
