How to Unroot Your Desire 816 & Get The Stock 5.0.2

Knowledge that you need to know:

To unlock your bootloader goto htcdev.com

Left-shift click inside a folder and click “open a command window” to open a local cmd window and run commands from there.

Access bootloader by powering the phone off and then holding the power button and the down button.

Install a custom recovery by flashing it. Have the phone in fastboot and connected to the pc. You will need fastboot.exe in the same folder as the recovery image. Then enter in command window : fastboot flash recovery recoveryname.img

Prerequisites:

Phone : ***HTC Desire 816 Virgin Mobile***

Please use TWRP. I have not used CWM ever since I tried TWRP. Always make sure to use the latest version of TWRP. Which can be found here. ( I use openrecovery-twrp-2.8.5.0-a5.img )

1) Have TWRP installed as your custom recovery ; Boot Unlocked

Information at top on how to install custom recovery and boot unlock

2) You need the OTA Lollipop update for the HTC Desire 816 – 1.4 GB

3) Here is a folder containing everything else that you will need.

Make sure to keep all files together in the same folder.

4) Adb Drivers and HTC Drivers have to be up to date

Procedure:

Backup.

Always backup your phone before doing anything that could possibly do damage to it. Whenever you do a backup always put a copy on your PC. Go to your custom recovery and use backup option.

Wipe.

Now you can -> wipe -> advanced wipe -> dalvik, cache, data, system

Flash and Lock.

Reboot to Bootloader *Do not install supersu*

Select fastboot and connect to your pc

Flash the StockRecovery.img file

Run oem lock.bat

Run.

Put your phone into bootloader -> fastboot -> connect to pc

Open the OTA Lollipop Update that you downloaded and wait.

After the update finishes that phone may lock onto white HTC screen. Simply shut phone off and turn it back on. Now just wait as your apps update and voila!

How to Unroot Your Desire 816 & Get The Stock 5.0.2

CM 12 for Desire 816 Review

The ROM for the CyanogenMod 12 for the HTC Desire 816 can be found here.

  For those of us who are not hardcore root enthusiasts, CM 12 is essentially a leading ROM that a lot of people seem to like. Unfortunately, many people struggle to properly install CM 12 or try to install it thinking it will upgrade their rooted phone to the normal stock 5.0.2. This however, is false.

  CM 12 is far different from the stock 5.0.2 – instead of being prompted to login into your google account and begin recovering data via HTC Backup, there is a prompt to login into your CyanogenMod account and there are no HTC apps whatsoever. ( If you install HTC Backup through the app store it will continuously crash, and lock up your phone ) Another fault I found, that I could not fix, was the: no data connection problem – that would not recognize my SIM card. This is a problem near everyone has, but I thought it invalidated keeping the ROM.

  Thus I began all over again and wiped my phone.
