[Moto X General] gciarami:
ATT MotoX 4.4 with a locked bootloader.

I followed Rooting Locked Bootloader: Step 2 (and did not do the optional userdata/cache wipe)

After "fastboot reboot", my phone got stuck in a reboot loop where it repeatedly showed the boot logo and turned dark.

I downloaded the 4.4 firmware and repeated step 2 with those files instead and my phone is now back to 4.4 and working.

I tried redownloading the 4.2.2 firmware linked in the instructions (and checked that the md5 hash was correct) and repeating Step 2 multiple times (twice), but I can't seem to get 4.2.2 working without the reboot loop :( .

Any suggestions? I am I correct in assuming that if I was on 4.4.2, then my Settings:About:Android Version would say 4.4.2 ?

Here's the output from my fastboot commands:
