HTC One (M7) Bootloader Unlock Guide

The HTC One, HTC’s high and mighty flagship phone of 2013, is not out in the market yet but the development community has already started working on various hacks and modifications for it. It’s a guarantee that the device will be extremely popular in the community, but before you are able to take advantage of all those hacks (such as custom ROMs), you’ll have to unlock its bootloader.

When you turn on your phone, the operating system (also called firmware) is loaded into memory from storage and then booted up, and the bootloader is the piece of code that starts this sequence of loading the OS up. By default, the bootloader is locked and allows only the official OS/firmware to be booted up on a device, which prevents one from running a custom ROM (or kernel).

That is where bootloader unlocking comes in, as by unlocking the bootloader the phone is then free to boot up into unofficial software, a custom ROM (or kernel) in this case. Most Android devices come with a locked bootloader, and while some manufacturers choose not to let users unlock the bootloader so as to not ruin the experience, most devices can be unlocked if a user chooses to.

This bootloader unlock guide for the HTC One will walk you through the entire procedure with easy step-by-step instructions, allowing you to unlock the bootloader and then install custom ROMs and modification as and when you please.

However, unlocking bootloader has a few disadvantages and risks involved:

  1. Unlocking the bootloader will void the warranty of your phone permanently and you’ll be unable to get any support under warranty from HTC.
  2. All the data on your phone will be wiped, including personal content on the internal storage such photos, music, videos and other files. You can take a backup of everything though and restore it later on.
  3. While you’ll be able to obtain official software updates from HTC after unlocking bootloader, there are chances that it might cause issues so it’s best to not accept official software updates.

So make sure you’re okay with the risks involved in unlocking the bootloader as given above, then continue reading below for the bootloader unlock procedure.

Compatibility

The procedure described below is only for the HTC One. Do not try it on any other device.

Warning!

The methods and procedures discussed here are considered risky, so try them out at your own risk, and make sure to read each step carefully before attempting anything. We will not be held responsible if anything goes wrong.

Requirements

  1. Unlocking the bootloader causes all the data on the device to get wiped, including everything on your internal storage such as photos, music, videos, etc. First, backup installed apps and other data such as contacts, messages, bookmarks, etc, by referring to our Android Backup Guide for help. Then, copy everything from the SD card to your computer, which will also include the apps and data you backed up.
  2. You’ll need to have the drivers for the phone installed on your computer. Download the HTC Sync Manager and install it on your computer, which will install the drivers as well.
    Download HTC Sync Manager
  3. Download Fastboot.
    Download Fastboot | Filename: Fastboot.zip
  4. Extract the Fastboot.zip file you just downloaded to a convenient location on the computer to obtain a folder named Fastboot which will have four files inside it. To keep things easy, extract the Fastboot folder to drive C.
