If you run a Moto X or any of the DROID family of devices from 2013, or one of a handful of other devices from HTC from 2013, then you now have a way to unlock the bootloaders for those devices thanks to a new tool that can be found over at XDA called SunShine Bootloader Unlock. Essentially this is a bootloader tool for modern HTC and Motorola devices and is not geared just towards the Moto X and Droid line from last year. If you're someone that isn't new to modding your device, you may have even already heard of SunShine before and sort of know the ins and outs.
The tool comes by way of a team of developers called TeamAndIRC, and the bootloader unlock tool was just released for these devices this afternoon so it's fresh which means this may be your first chance to complete this task. It also means that we don't have any knowledge of how the tool works for any of the included devices that TeamAndIRC has added to the list, so use at your own discretion and always, make sure to do a solid backup of anything on your device before you attempt to use things like this.
As noted, SunShine Bootloader unlock tool will try to give users a temporary Root if you do not already have a rooted device, but it's mentioned that it isn't exactly a stable process so you may want to make sure to have root before you attempt to unlock your bootloader. If you comfortable in doing these processes and are eager to gain access to the benefits of a rooted device with an unlocked bootloader, you can find the details for the SunShine Bootloader unlock tool at the source link below, minus the root process for your device of course, which you'll want to find the instructions for before hand if you need them. The included devices are the Motorola Moto X, Droid MAXX, /Ultra Mini,(Android 4.4.3 and below on all of these devices, 4.4.4 on some of them)The Moto G with Android 4.4.3 only for now, the HTC One Mini M4, the HTC One M7, M8 and E8, the HTC J Butterfly, the HTC One X(Evita), and other modern HTC devices with a denotation to test the tool and that SunShine will alert the user as to whether or not it will work. It should also be noted that to unlock the bootloader for a listed device, it will cost the user $25, which developer jcase mentions is how you know the tool will work for your device.
