If you are purchasing the Moto X Pure chances are you are doing so because you want to be able to easily modify your device. Motorola makes it super easy to unlock your bootloader, but in doing so you have to agree to void your warranty, and the boot image displays a warning stating that the bootloader is unlocked. If you need to send your phone back for warranty purposes you would need to first get rid of that bootloader unlock warning. Also the screen is just obnoxious to look at when booting up your phone.
The fix is pretty simple all you have to do is flash a modified boot logo.bin. To apply the fix you will need to have the sdk installed on your PC. You will also need to be able to run a simple fastboot command. Head to the link below for the file and full install instructions. Keep in mind that your warranty may still be void, and the best way to ensure your warranty would be to omit unlocking the bootloader.
