Kinda odd that you've got all these people bashing your work, as you've obviously put a LOT of effort into it. I, for one, found it to be the simplest utility I've tried for the Razr Maxx HD (XT926 on 4.1.2), though one thing worth noting is that nowhere in THIS thread did I find information specifically pointing out that you must FIRST be in AP Fast Boot mode, which I suspect may have been the problem for some of the others here.
I ran the Ultra-Lite Version, and was able to root AND unlock with amazing simplicity. You must root BEFORE unlocking. I think each step took literally less than 5 minutes.
If you want this to work, you MUST do the following:
1) Power off your phone.
2) Hold down the Volume Down and Volume Up while holding down the Power button.
3) Eventually, a menu will appear, and you can let go of the buttons.
4) When this menu appears, press Volume down to scroll until you reach an option titled AP Fast boot, and press volume up to select.
5) Once you reach the AP fast boot section, just use the utility's built in features to reflash the ROM!

I did stumble across one glitch in your program though. At one point, I started to unlock before rooting. At the confirmation screen, it asks if I want to continue, or cancel. Upon pressing cancel, it proceeded to attempt unlocking anyway. I had to manually abort the process. Other than that, I think your utility is fantastic.
