Like mentioned in the OP. I made a 1 click for the HD that removes all the necessary files that would over write you custom recovery AND then flashes either CWM or TWRP for you. Just need windows and a phone. No fastboot, no nothing. Just plug in and click.
Here if you want it
TWRP will work on any XT926 with an unlocked bootloader.
Download the latest version of TWRP from here: http://goo.im/devs/Hashcode/vanquish/
I believe someone has created a tool that will install this for you in a "one-click" fashion. I would recommend that to anyone not really familiar with fastboot or has lesser confidence in using this method.
Here are instructions: http://www.theandroidsoul.com/twrp-a...razr-hd-xt926/ (Ignore the TWRP download links from that article because they may be old.)
