[Desire 626 Q&A, Help & Troubleshooting] doyin116:
This is the process for unlocking bootloader and it's straightforward. However, if you find it complex, I suggest you check YouTube to search for videos on 'how to unlock HTC bootloader from htcdev'

Unlock bootloader

- Enable "Unknown Sources" on your phone:

- Settings->Security: Check "Unknown Sources" checkbox

- Enable "Developer Mode" and enable "USB Debugging" and "OEM Unlocking" settings

- Settings->About->Software Information->More: Tap on "Build Number" until it tells you that Developer Mode is enabled.

- Settings->Developer Options: Enable "OEM Unlocking" and "USB Debugging" options.

- Actually unlock the bootloader by going to the HTCdev "Unlock Bootloader" website (www.htcdev.com/bootloader) and following the directions to unlock your bootloader. You will need to create an account on this website before being able to unlock the bootloader. I'm not going to provide step-by-step instructions for the bootloader unlock procedure since the HTCdev website already provides a step-by-step procedure. However, here are a few key notes regarding this procedure:

- The bootloader unlock procedure will reset your phone back to factory defaults. Make sure to backup anything that you need on the phone before unlocking the bootloader. You can optionally install the "HTC Sync Manager" (link provided on HTCdev website) to backup your phone before starting the process.

- In the "Select your device" box on the first screen of the bootloader unlock procedure, select "HTC Desire *" as the device type.

- If you are running the latest firmware on your phone, you do not need to worry about the phone update page when you first start the unlock process - just scroll to the bottom of the screen and click the "Proceed to Step 1" button to start the procedure.

- You will need to install Java if you don't already have it installed - there is a link to download Java right on the same page as the bootloader unlock procedure.

- You will need to download and install the fastboot binaries provided in step 4 of the bootloader unlock procedure. Unzip the fastboot.exe file included in the zip to a directory that you will use to root your HTC Desire 626s (I recommend creating a new directory for this - something like "C:\HTC626s") - later, you will also put the other files you need (recovery image file and SuperSU binary .zip file) into this same directory so that everything is in one place.
