If you have a Dev Ed Moto X you can take the updates and then re-unlock or unlock and root. Also, there is no reason to roll back to other firmwares like the OP of that post did. Looks like he bricked his phone when he tried to roll back to 4.2.2 for whatever idiotic reason. If you do a search here it's covered a lot, if you have a DE you can take all the updates and then unlock and root via the Motorola site. You can even unlock and root prior to taking the updates. Once you try to roll back to a previous version you WILL brick your phone. It's been covered repeatedly.
