its strange, I get this problem after doing a mainboard swap. It did a bootloop when I first started it, thought it may of been a corrupt system so just did the kitkat update, was able to root and unlock the bootloader on the new board and that is when I noticed the date. flashed back to JB with house of moto universal script and I get the same bootloop. My phone worked fine with the old mainboard. I just changed it because the sim card reader would go out. Either I got a bad board or something. I'll continue to investigate but any input would be appreciated.
