The OnePlus One is one of the coolest smartphones to come out over the last couple of years. It did come pre-loaded with CyanogenMod, but unfortunately, that partnership when pear-shaped not long ago.
Still, they are bringing the second edition soon which will hopefully be popular enough to ditch the requirements one must have to purchase the device such as the original invite system. If you already followed our guide on how to root the OnePlus One and are wishing to return the device back to stock Android with the system internals locked again, you can do that by following the guide below.
BEFORE WE BEGIN
- You should already have root access on the device before coming here.
- You can use the unroot method to start fresh and flash a different custom ROM, or you can use it to return completely back to stock.
- You can send it away under warranty for free repairs if you are choosing to return back to stock, providing you are still under the warranty period.
- You will need a computer to follow the guide.
- Since we are using a computer, you’ll need to connect the smartphone to the computer. That means enabling the USB Debugging Mode from the Developer Options menu.
- Make sure you have enough battery power to prevent the smartphone from shutting down.
- Hit up the Java link here and make sure you have the Java for your operating system.
- Download the OnePlus One toolkit from XDA here.
HOW TO USE THE TOOLKIT TO UNROOT THE ONEPLUS ONE SMARTPHONE WITH EASE
1. Download and install the Java if your computer isn’t up to date already.
2. Restart the computer if you did the fresh installation of Java.
3. Click the executable file for installing the toolkit on your desktop.
4. Click the button which says download ADB drivers, followed by installing ADB drivers.
5. Click the option that says Enter Fastboot/Recovery Mode.
6. Choose the OEM lock option.
7. It should automatically reboot the device by itself when it’s finished locking the device.
You are now working with a locked device without any root access, just the way the device manufacturer intended. You’ll find that the ROM running on your OnePlus One smartphone is actually CyanogenMod which is a name most people know from the custom ROM community. But don’t be fooled: the CyanogenMod ROM in this particular instance is actually the stock ROM that the OnePlus One smartphone ships with. They happen to break up their partnership in future versions of the phone and OnePlus goes back to using Android, but the original OnePlus did definitely ship with CyanogenMod as the stock ROM.
