Theis a massively popular phone right now -- so popular that its manufacturer is . Should you be lucky enough to own this blisteringly fast Android powerhouse, then you've no doubt already marvelled at its terrific screen, punchy stereo speakers and solid build quality. If all of the One's built-in features are still not enough to satisfy you, then perhaps you're ready to take your handset to the next level -- and that means getting root access.
Root access allows you to do all kinds of amazing things, such as installing custom firmware, removing stubborn applications and generally gaining more control over your device. Like so many things in life, rooting isn't without its risks. Tampering with your phone's software invalidates your warranty, and if something goes wrong during the procedure you could end up with an expensive paperweight. As always, CNET UK can take absolutely no responsibility for any damage or loss of data that may occur from following this guide.
Mercifully, the process outlined below is pretty foolproof and we've already tested it ourselves, so assuming you're still brave enough, let's get down to business. The guide assumes you're using a Windows-based PC.
1. Back up your phone
To root the HTC One you'll need to unlock the phone's bootloader. This wipes everything on the handset, so make sure you've already backed up all of your valuable data, such as photos, videos and audio. Once you move onto the next step, you've got to be prepared to lose it all.
2. Unlock the phone's bootloader
Before you can do any rooting, you'll have to unlock the HTC One's bootloader. Visit HTC's dev site and register, if you haven't already. Follow the steps provided to place your phone into Fastboot mode and request the device ID token required to perform the unlock. You'll need the latest version of the Android SDK to do this, so make sure you've downloaded it beforehand.
Once you've got the token, you'll need to input it into the HTC dev site, after which point you'll get the code used to unlock the phone, plus instructions on how to do it. During the unlock process you'll need to place all related files in a folder. Make sure you place it on your desktop, as you'll be putting more stuff in there as part of the next step of the guide.
3: Download TWRP recovery
Grab the latest version of TWRP recovery (currently 126.96.36.199) and place it in the same folder where you downloaded the previous files.
4: Open up a command prompt
You'll need to regress to the world of MS-DOS for this next bit, which might bring back unhappy memories for anyone over the age of 30. Open up the Start menu in Windows and type "cmd" and press enter, then use "cd/desktop/xxxxx" (with the "xxxxx" being the name of the folder) to navigate to the folder where you previously downloaded all the files.
5: Place your HTC One into fastboot mode
You're prepped PC-side, but now you need to make sure your HTC One is ready for the rooting process to begin. Place the phone into Fastboot mode by turning it off completely and then holding down the Power and Volume Down buttons. Select 'Fastboot' using the volume rocker and press the power button to select it. Now connect your phone to your PC using a Micro-USB cable.
6: Flash TWRP recovery to your HTC One
In the command prompt, type "fastboot flash recovery twrp.img". The TWRP recovery will then be flashed to your phone. After this has completed, restart your phone.
7: Download and install SuperUser
Download the SuperUser application from here and copy it to the root of the phone's internal memory. To install it, you'll need to boot the phone into recovery mode. Switch off the handset and hold down the Power and Volume Down buttons again. Navigate to 'Recovery' and press the power button. From the next menu, tap 'Install' and then select the SuperUser.zip file you copied across earlier. Once that process is complete, reboot your freshly rooted HTC One and enjoy.
