Fastboot Install Method (No Root Required):

On your device, go into Settings -> About and find the Build Number and tap on it 7 times to enable developer settings. Press back and go into Developer Options and enable USB debugging. From your computer, open a command prompt and type:

adb reboot bootloader

You should now be in fastboot mode.

Download the correct image file and copy the file into the same folder as your platform-tools. Rename the image to twrp.img and type:

fastboot flash recovery twrp.img

fastboot reboot

Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.
