These are the guidelines to unlock the Verizon Motorola DROID Turbo so you can then move on to installing a custom recovery and rooting the device. Without unlocking the bootloader of your DROID Turbo smartphone first, neither of those two things will be possible.

Like you know, a bootloader is the first thing to load when you turn your Motorola DROID Turbo smartphone on by pressing the Power button. The bootloader itself will boot up on your Android operating system. In fact, it is your bootloader that will determine what partition is to load after assessing your requests. By default, this is usually the Android operating system because it’s programed to kick in if no other requests are made. But should you press the hardware button combination for recovery mode, it is your bootloader that will choose to boot that recovery mode for you.

As you now know, the bootloader is an important part of your mechanics. By default, your bootloader comes “locked” to the point where it prevents any additional operating systems from loading instead of the official ROM that is given to your device by Android, the manufacturer and phone carrier networks.

Files You Need

  • Download the Sunshine app from here.
  • To unlock the bootloader of your DROID Turbo, you must be running the build number SU4TL-44 and the 23.21.44.quark_verizon.verizon.en.US vzw system version.
  • Note that unlocking the Motorola bootloader is always going to void the warranty. While that might be true, there may be some phone carrier networks that are still willing to cover you under warranty. Check with your mobile provider before unlocking the bootloader if the warranty is something that is important to you.
