Root HTC Droid DNA

Root HTC Droid DNA

Here is a complete guide for anyone interested in rooting the HTC Droid DNA. The insecure boot image, TWRP recovery, CWM recovery and SuperSU files used in this guide are not my own developments, and their developers have been credited in the end of this post.
I am only writing this as a newbie-friendly guide for everyone, and am providing my own SuperSU, su and busybox installer zip file that includes everything you need for full root.

1. Unlock the bootloader of your device by visiting the HTC bootloader unlock page. Warning: This will wipe your data.
   UPDATE: Thanks to Verizon, the official bootloader unlocking method mentioned above no longer works. Please refer tothis method for unlocking the bootloader.
2. Download ClockworkMod or TWRP recovery for the device and rename it to recovery.img (or keep the existing name and change recovery.img in the command below to that name).
3. Download the SuperSU and busybox package and put it on your SD card.
4. Put your phone into bootloader mode and connect it to your PC via USB.
5. On your computer, make sure you are in the folder where you downloaded the recovery file and use this command to flash the recovery:
   Code:

   fastboot flash recovery recovery.img

6. Finally, reboot your device into recovery, flash the SuperSU and busybox package and reboot your device.

You should now have root access.
