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?

Boot OnePlus 6T Bootloader 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.

Using Advanced Reboot Menu

Stock OxygenOS comes with a hidden option to enable the Advanced Reboot Menu. The menu, once enabled, will allow you to easily boot your OnePlus 6/6T into Fastboot Mode or Recovery Mode by simply using the Power Menu.

  1. Open the ‘Settings’ app on your phone and enable the hidden Developer Options
  2. Scroll to the very bottom of the settings menu and select ‘System’

  6. Finally:

    • Press ‘Bootloader’ to boot your OnePlus 6/6T into Fastboot Mode

Method 2: Using Physical Button Combination

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.

This method is more apt for users who have a third-party firmware (custom ROM) installed on their phone since the advanced reboot menu is only available on the OxygenOS software. You can still use this method if you have the OxygenOS software installed. The application of this method extends further as well.

  1. To enter Fastboot and Recovery Modes using the physical button combination, you will first need to power off your OnePlus 6 device completely. To do this, simply press and hold the Power button to bring up the Power menu and select ‘Power Off’.
  2. Once you have done that:
    • Press and hold the ‘Volume Up’, ‘Volume Down’, and ‘Power’ keys together to enter Fastboot Mode
    • Press and hold the ‘Volume Down’ and ‘Power’ keys together to enter Recovery Mode

Method 3: Using ADB Command

The third and last way to boot the OnePlus 6/6T into Fastboot and Recovery Modes is by using ADB. The Android ADB tool offers a couple of commands, which when executed from the PC over USB can boot your phone into the said modes. This method can come in really handy while performing things like bootloader unlocking, custom recovery installation, etc.

In order to use this method, you will need to have USB Debugging enabled on your phone, ADB installed on your PC and some basic knowledge of command-line syntax. Further, make sure that you have the latest OnePlus USB Drivers installed on your PC.

Once you have done the things said above, follow the steps listed below.

  1. Connect your OnePlus 6/6T to your PC using the USB cable
  2. Make sure that USB Debugging is enabled on your phone
  3. Launch the PowerShell or Terminal in the same directory where ADB is installed on your PC
  4. Enter the following command to ensure that your PC can recognize your phone over ADB and establish a proper connection:
    adb devices
  5. If you’re using ADB for the first time, your phone will prompt you to allow USB debugging. So, press “Allow”.
  6. Now enter the ADB command depending on the mode you want your phone boot into.
    • To enter Fastboot Mode on your OnePlus 6/6T, use:
      adb reboot bootloader
    • To enter Recovery Mode on your OnePlus 6/6T, use:
      adb reboot recovery

That’s it! You have just learned how to enter different boot modes on your OnePlus 6/6T using three different ways. These modes should come in handy if you want to perform a factory data reset, unlock the bootloader, flash a custom recovery, unbrick the phone, etc.
