As promised, HTC has released a tool that can be used to unlock the bootloader of any Android phone manufactured by the Taiwanese company after September 2011, including the Evo 3D, Flyer, Amaze, and Sensation. Additional devices will be supported in the coming months, but in the meantime, you can still head over to XDA for less official solutions.
HTC is committed to listening to users and delivering customer satisfaction. We have heard your voice and starting now, we will allow our bootloader to be unlocked for 2011 models going forward. We plan on releasing the updates that will allow you to unlock your bootloader in the coming months, please keep an eye on this website for more details on which devices will be adding this feature. We are extremely pleased to see the energy and enthusiasm from our fans and loyal customers, and we are excited to see what you are capable of. HTC eagerly anticipates your innovations.
The tool will not unlock the SIM lock, and HTC warns that the tool invalidates DRM so certain apps will not work. As with any rooting/jailbreaking procedure, there is always a small danger of bricking your phone, so use at your own risk.
