This is a Non-Developer Edition Droid MAXX
You are running into a similar problem that others (including myself) have, where the 4.4 update partially installed. If you try to SBF (using RSD Lite, HouseOfMoto, fastboot, or otherwise), It will not succeed because the bootloader doesn't like the fact that you wen't backwards to an older boot.img. Currently, we don't have a new boot.img from the KitKat update because that file is not contained anywhere in the update.zip (it only has a boot.img.p patch, rather than a whole new img file), and we don't have the SBF yet. Once the SBF comes out, this should fix the problem for you entirely as it will replace your boot.img, your recovery, and system partition regardless of their current contents.
