This is a guide on how to Root, add a Custom Recovery, and Unlock the Bootloader for your HTC Desire 816 and HTC One models!\r
(Sorry; no S-Off at this time for the 816. HTC One devices S-Off IS supported depending on your device).\r
\r
[FOR HTC DESIRE 816]\r
The AIO zip in step 5 includes and adds, Root, Busybox, Init.d, & Write Protection Removal to give us a working /system RW permission and access to our devices like how it was on Jellybean and previous versions.\r
(If you have already rooted just re-flash the new step 5 zip to gain the extra features but just be sure to wipe cache & dalvik cache.)\r
\r
[FOR HTC ONE M9 / M8 / M7 / MAX]\r
Simply follow the steps to flash each portion in the video meaning the steps to get the bootloader unlocked, then to flash the recovery and to finally flash the SuperSU .zip file IN THE EXACT SAME WAY IT IS DONE IN THE VIDEO! \r
These links are below as well and yes I have updated the recovery installers for each device I have listed in the description below.\r
\r
Back up your device information before you begin to your PC, Google Drive, etc. so that you may continue without risk of losing it. This is necessary because some devices will fory reset when you select Yes to unlock the bootloader.\r

If you want to return to pure stock for warranty:\r
Go into the SuperSU app and remove root with the one click option in the settings of the app.\r
Now go into your bootloader, enter fastboot, then plug your device in to the PC.\r
\r
When your plugged in and it says fastboot USB, flash the stock recovery which can be done with this .exe here:\r
\r
\r
Afterwards, press reboot to bootloader and go into fastboot mode again and make sure it says fastboot USB.\r
\r
Now you can go into the Local Disk C:/adb folder and open a command prompt.\r
Type the following command:\r
fastboot oem lock\r
\r
YOUR DEVICE WILL SAY RELOCKED BUT THIS DOES NOT MATTER WITH WARRANTY AS LONG AS YOU REMOVE ROOT; PUT THE RECOVERY BACK TO STOCK, AND RELOCK THE BOOTLOADER! \r
*CONFIRMED*\r
\r
To ensure your device is pure stock and able to receive updates you can go the extra step and flash the RUU from this thread:\r
\r
\r
You can use the same process in the video to root again after updating your device.\r
\r
Also, if you have never updated your VM Desire 816 since purchase then the RUU above will update the stock bootloader from 3.18 to 3.19.
