Can't exit recovery mode after intalling HD revolution 71.1
Summing up the solution from the comments, as neither OP nor the "solution provider" posted an answer:

Per Johnny Wrights recommendation I was trying to update TWRP to 2.6.3.3:


Plug in the phone to the PC via USB and make sure the phone is in FASTBOOT USB mode from the bootloader menu.
On the PC, I installed "Minimal ADB and Fastboot". Running that from the command line (cmd.exe) you type fastboot flash recovery then drag the file. (watch the youtube video – it will make more sense). I my case it was the 2.6.3 TWRP .img file. That pushes the update to the phone.
I already had the HD 71.1 zip on the phone. I installed that via the TWRP install and from there it booted up normally.
