How To Enter Fastboot & Recovery Mode on the OnePlus 9 & 9 Pro

Below you will learn how to boot your OnePlus 9/9 Pro into fast boot and recovery mode. If you are a power user who likes to install custom ROMs and custom builds, you most likely have booted your phone into recovery mode at least once. If you have gotten a brand new OnePlus 9/9 Pro, you might not know how to do it.

Below we will go into detail about what is Fastboot, recovery and how can you access them on your OnePlus 9/9 Pro.

How To Enter Fastboot and Recovery Mode on OnePlus 9/9 Pro

What is Fastboot?

Fastboot is a mode independent of the phone’s operating system. It can be accessed without loading the entire OS. Fastboot allows data to be written to the phone’s internal storage. This data can be a custom ROM, a custom kernel, or a recovery. Furthermore, the only way to take advantage of all the features mentioned above is to unlock the bootloader of the phone. OnePlus phones come with a locked bootloader which can be easily unlocked through fastboot.

What is recovery mode?

Recovery mode is an important part of all Android phones. It is a stand-alone piece of software that allows users to access a number of functions without having to boot the entire OS. This is a very useful feature, especially if the firmware or the OS of the phone is corrupted.

Enter Fastboot and Recovery Mode through Advanced Reboot

The fastest and easiest way to boot your OnePlus 9/9 Pro into Fastboot and Recovery mode is by using OnePlus’ own Oxygen Advanced Reboot Menu. This is an option that OnePlus has included to make it easier for power users to quickly enter these modes.

  1. Open the Settings menu on your OnePlus 9/9 Pro.
  2. Go to System and tap on Developer Options. You will have access to a number of special options.
  3. Scroll down until you find an option called Advanced Reboot. It should be disabled by default.
  4. Tap the toggle to enable it. The toggle should turn blue.
  5. Now press and hold the Power button. The Power menu will pop up on the right side.
  6. The menu includes the following options: Power off, Restart, Recovery, Bootloader and Screenshot.
  7. Tap on Recovery to enter recovery mode, or tap on Bootloader to boot into Fastboot.

That is it. If this method works and you are happy with it, you can stop here. But if you are running a custom ROM or you do not have the Advanced Reboot option, then check out the second method, which includes the traditional hardware keys.

Enter Fastboot and Recovery Mode using Physical Keys

The second method involves OnePlus 9/9 Pro’s physical buttons. This method is next in line in case the first one does not work. This is also easy to perform, even though it is a little trickier.

  1. Press and hold the power button. Tap on Power off to turn your OnePlus 9/9 Pro off.
  2. Once the phone is off, you have two options:
    • To enter recovery mode, press and hold the volume down and power keys at the same time.
    • To enter fastboot mode, press and hold the volume up and power keys at the same.

This is the second way to access fastboot and recovery on your phone. If for some reason this method does not work either, then follow the third one, which is also the last way.

Enter Fastboot and Recovery Mode using ADB commands

The third method is the last resort in case the first two do not work. If you are running a custom ROM and the physical keys are broken, then ADB commands are the only choice. For this you need to install the latest USB and ADB drivers for your OnePlus 9/9 Pro.

  1. Connect your phone to your computer using a USB cable.
  2. Open CMD/Powershell on your computer.
  3. Run the following command to make sure the computer recognizes your OnePlus 9/9 Pro:
    adb devices
  4. Now you have two choices again:
    • If you want to boot your OnePlus 9/9 Pro into Fastboot Mode, use the following command:
      adb reboot bootloader
    • If you want to boot your OnePlus 9/9 Pro into Recovery Mode, use the following command:
      adb reboot recovery

Once you run the following commands, your OnePlus 9/9 Pro will turn off and go into Fastboot/Recovery Mode. That is all you have to do. Now you can flash factory images, custom ROMs, unlock the bootloader, and much more.
