Unlocking the bootloader of your HTC smartphones will allow you to
root and install new custom ROMs. This is a guide that should be used by
those users who want to tinker with their phone’s OS and free its OS so
that you will be able to flash unofficial software for your phone.
Step 1
After powering down, press Volume Down and while pressing Volume Down, press Power
holding both buttons to start the device into Bootloader mode (now
Download mode for One M9 and newer devices). If you have difficulty,
power up normally, go to Settings->Battery and deselect Fast boot.
Power down and try again.
-
Step 2
Use the Volume buttons to select up or down. Highlight Fastboot and press the Power button.
NOTE: All new HTC devices shipped since One M9 support download
mode instead of bootloader mode for this step. And for select HTC
devices with Android Lollipop and all devices that receive Marshmallow,
you will need to first manually enable OEM unlocking in Developer options in order to allow the bootloader to be unlocked and proceed with the next steps. To access the OEM unlocking setting on your device, open the Developer options
in the system Settings. On Android 4.2 and higher, the Developer
options screen is hidden by default. To make it visible, go to Settings > About > Software information > More and tap Build number seven times. Return to the Settings screen to find Developer options and check OEM unlocking.

Step 3
Connect the device to the computer via a usb cable
