This bootloader unlock tutorial compatible with all HTC models released since 2013 or later. Perhaps most of the users will say that there’s too many necessary steps to make for bootloader unlock. But we can assure you, they are all sufficiently simple. Thanks to the new HTC policy, from now on, all HTC devices are made with open and easily unlockable bootloader file, which inevitably will be required in this process.
We’ll use the Hasoon‘s all-in-One Toolkit to help you automate most of this tutorial.
