Odd issue -- after flashing, phone reboots to fastboot and loses custom recovery.. topic

So, I had to replace my HTC One.

The new one is 1.55 -- I am still S-On.

Today I flashed CWM 6043 using fastboot after unlocking the bootloader through HTC.

I flashed SuperSU.

I attempted to flash two of the newer roms (InsertCoin and Renovate) because I wanted Sense 6.

After successfully going through the flash, the phone reboots and goes straight back to Fastboot. If I go into the Bootloader and try to go into Recovery, it just kicks me back to the bootloader. I can then use fastboot to reflash CWM 6043 again and do it all over.

Same thing.

Every time.

Thoughts?
