How to unlock HTC One M9 Bootloader [Guide]

HTC One M9If you are looking to increase the value of your HTC One M9 or gain root access you’ll need to first unlock the bootloader. The bootloader is the booting process which must be altered if we are to gain control of the internal system for flashing custom ROMs, custom recoveries and anything else that’s legal but away from the HTC business plan.

REQUIREMENTS

The guide below is only for the HTC One M9 released during 2015. Do not try the guide on the M8 or the M7 handsets.

BEFORE WE BEGIN

  • The most important part is backing up your data such as call logs, SMS texts, pictures, videos, music files, phone contacts and other data you don’t want to lose. We must apply a full reset when unlocking the bootloader and doing that wipes all the data clean. You will lose everything. You can back up and restore that data later so you have it all back again.
  • Backing up to the internal SD card is safe and will keep your data protected for a full restore later. You can also use third-party apps from Google Play such as Helium. Once you have root access you will probably prefer to switch over to the Titanium app from Google Play or take a NANDroid backup from inside the custom recovery of your choice. Install the up-to-date USB drivers on your Windows PC. You can find the HTC USB drivers here.
