If you own the OnePlus 6 or 6T and have yourself indulged into things modding, flashing, etc, then you might need to enter Fastboot and Recovery modes at some point. Even for an average user, knowing about these boot modes and how to boot the phone into them can be useful in various situations. Like while unlocking the phone’s bootloader, restoring the stock OxygenOS firmware, performing a factory data reset, and more.
In this guide, we will show you how to enter Fastboot Mode and Recovery Mode on OnePlus 6/OnePlus 6T using the following three ways:
- OxygenOS Advanced Reboot menu
- Physical button combination
- ADB commands.
Before we get to the instructions, let us first understand what these boot modes are and when and why you might need to boot your phone into them.
What is Fastboot Mode?
Fastboot Mode on the OnePlus 6/6T is an interface that enables your computer to connect with your phone’s bootloader over USB using the Android Fastboot tool.
When it comes to practical application, Fastboot Mode is generally used to unlock the bootloader, flash the device partitions for upgrading/downgrading the software, for unbricking, and even for installing a custom recovery such as TWRP or flashing patched boot images for rooting.
What is Recovery Mode?
Recovery Mode on the OnePlus 6/6T is a bootable partition where the stock recovery (OxygenOS recovery) is pre-installed by the manufacturer (OnePlus). It can be used to perform a variety of tasks to recover the phone from a boot loop or to fix software-related issues. These tasks include performing a factory data reset, sideloading software updates, and more.
In case you have a custom recovery installed instead of the stock recovery, you could use it to install custom ROMs/kernels/mods, take NANDroid backups, format/erase partitions, flash root solutions like Magisk, and more.

How to Enter Fastboot & Recovery Modes on OnePlus 6/6T
Booting your OnePlus 6 or OnePlus 6T into Fastboot & Recovery Modes can be done through three different ways/methods. All three of these methods have been discussed below along with their corresponding instructions.

The second way to enter Fastboot and Recovery Modes on the OnePlus 6/6T is by pressing a dedicated button combination while your phone is powered off.
