So you’ve already cracked the screen on your beloved Moto X when it just ‘somehow’ fell to the ground, and you’re worried that Motorola will void the warranty because you’re phone is rooted. Developer editions aside, there probably isn’t much of a chance the tired and overworked device repairman will discover and immediately reject your device, but it wouldn’t hurt to refresh your device back to ‘brand new’ as a safeguard.
To help with this, XDA Recognized Developer mattlgroff has created a tool called Moto X Restore Utility, and it does exactly what its name suggests. It has three primary functions and they are pretty self explanatory, them being:
Download the latest Moto X USB drivers
Download the latest Moto X firmware (Android 4.4.2)
Restore your Moto X
Additionally, mattlgroff has made the Moto X Restore Utility compatible with all three major PC operating systems – Windows, Mac, and Linux. To help new users get a grasp of the tool on their PC, mattlgroff has provided detailed written tutorial for users, as well as link two video tutorials for the Windows version. The tool however, only works with the two developer editions of the Moto X (who really have no need to worry), and those locked in with AT&T, T-Mobile, Sprint and Verizon, so international users may be out of luck.
