How to Root HTC M8

[SIZE]

[COLOR]

WARNING !

You will lose all your data and it is possible that you may brick your device

All described operations you are doing at your own risk.

Step 1Before rooting the HTC M8, the bootloader of the handset must be unlocked. This can be achieved by heading over to HTC’s Dev website which has a detailed step-by-step guide on how to unlock the bootloader along with download links for all the files required during the process. Users, however, are first required to register on the site.

Once the boot loader has been unlocked, the device will reboot into Android OS.

Step 2After setting up the device again, transfer the SuperSU ZIP file to the internal storage of the HTC M8. With the bootloader unlocked, it is now time to install TWRP recovery on the handset.

TWRP recovery for One M9 can be downloaded from here.

Step 3Transfer the TWRP recovery image file to the same folder containing the ADBFastboot that was created while unlocking the bootloader of the handset in Step 1. Also, make sure to rename the file to something simpler like “twrp.img”.

Step 4 In the same command prompt window that was used in Step 1 to unlock the bootloader of the HTC M8, enter the following command

adb devices

Note Mac owners, make sure to prefix a “.” before executing any fastboot or ADB command.

This command will confirm whether the HTC M8 is being successfully detected by the computer or laptop it is connected to or not.

Proceed to reboot the handset into fastboot mode by entering the following command

adb reboot bootloader

Once the device boots into the bootloader mode, use the Volume keys to navigate to the fastboot option and confirm the selection by pressing the Power key.

Step 5 Now, enter the following commands one by one

fastboot flash recovery twrp.img

fastboot reboot

If all the steps mentioned above were followed properly, TWRP recovery must have been successfully installed on the HTC M8.

Step 6 Once the recovery has been installed, it is now time to gain root access on the HTC M8 by flashing SueprSU. Switch off the handset once again and proceed to reboot it into bootloader mode by pressing the Volume Down + Power button simultaneously. Then, navigate to the [I]Recovery [I]option using the volume keys and confirm the selection by pressing the Power button.

After the HTC M8 has boot into recovery, tap the ‘Install’ button and select the SuperSU ZIP file. Once the ZIP file has been installed, reboot the handset by selecting the ‘Reboot system’ now button.

The first boot after installing SuperSU might take some time as Android OS needs to rebuild cache for some of the apps. After the device has booted back into Android, open the SuperSU app to make sure that it does not need to update its binary. If not, then the One M9 has been successfully rooted.

Since there is a custom recovery installed on the handset as well, installing
