How to Root OnePlus 3/3T

Rooting OnePlus 3 and OnePlus 3T is pretty easy. The rooting procedure of 3/3T can be broken down into 3 steps, Unlocking the Bootloader, Installing TWRP Recovery & finally installing SuperSU to gain root access. Each new step relies on the previous step to have been completed, and a basic summary of each part is:

Stage 1: Unlocking Bootloader: Unlocking bootloader is the first step to rooting and flashing custom ROMs. The bootloader is a code that tells your device’s operating system how to boot up. In order to avoid any system modifications, manufacturers lock their firmware. In order to install any 3rd party files into your system, you need to unlock the bootloader.

Stage 2: Installing a Custom Recovery: Stock recovery doesn’t allow any installation of 3rd party zip files. In order to install any other zip which is not signed by the firmware manufacturer, we need to install TWRP Recovery. TWRP is a powerful tool that gives control over the phone without needing to boot into Android. It can be used to flash a ROM or use minor app mods, as well as to create and manage backups.

Stage 3: Rooting: SuperSu is an app that grants you Administrator rights (called “root access”) to run or install specific apps restricted by the Android Operating System for security concerns.

After completing these steps, your phone will be rooted, the phone will have a custom recovery installed, and the bootloader of the phone will be unlocked. This, in our opinion, is the most practical and beneficial method for rooting your phone. It gives you some basic ADB/fastboot knowledge, and should hopefully help you have a decent understanding of what is going on. Also, this method will work regardless of what android version your phone has.
