After a long wait, finally the first Droid Turbo (XT1254) bootloader is unlockable. This is good news, because with unlocked bootloader you can do a significant mods to this smartphone, like flashing a ROM, installing a custom kernel, as well as gaining superuser privileges. We do not need Kingroot or Mofo app anymore to gain root access , we only need to install an app called Sunshine.
The Sunshine is a powerful bootloader utility, it’s developed by several talented developers like jcase and beaups. Start from Sunshine version 3.2, they added Verizon Droid Turbo (XT1254) in the supported device list, and eliminates dependence on Kingroot and others tools. So, we just need to use the Sunshine app to do all the work.
The app is designed for Verizon Droid Turbo with the current software version, Android 5.1 Lollipop with build number SU4TL-44. In order to utilize Sunshine, the phone must have the exact build number (SU4TL-44) or the bootloder unlock procedure will be failed. Except, the devs have updated the app to support the latest software version of Turbo.
It’s relatively simple to utilize Sunshine, just download the app from the official Sunshine site, the app will then check the compatibility with your phone. After that, you need to purchase a license. You only need to purchase it once, you can re-use it later on the same phone, it’s worth the money.
