How to Unbrick OnePlus 9/Pro via Fastboot Commands

In this guide, we will show you the steps to unbrick your OnePlus 9 and OnePlus 9 Pro device via Fastboot Commands. While the underlying OS has undergone a massive UI overhaul, however, the company has still stuck with its USP. And that’s to provide feature-rich devices to the masses at affordable prices. As of now, there has been an addition of a (or rather three) new member to this popular family.

The hype mill was already buzzing with a plethora of talks about the launch event, and the device seems to have justified it up to a larger extent. Along the same lines, it has already picked up the pace in custom development. This shouldn’t come as a surprise considering the fact that OnePlus always have impressive track records in this domain. And the ninth iteration is no different either. Once you unlock the bootloader, there is a plentitude of things to try out.

These include the likes flashing custom binaries, rooting via Magisk patched boot.img, among others. However, all these tweaks might bring in a few risks as well. If not done correctly, then you might end up with a soft-bricked or bootloop device. Fortunately, there’s an easier way out. You could unbrick your OnePlus 9 device just by using the Fastboot Commands. And in this guide, we will make you aware of just that. So without further ado, let’s get started.

Method 1: Unbrick OnePlus 9/Pro via Fastboot Commands

The instructions given below could also be used if you have a perfectly working device and just wishes to revert to stock. But in those cases, then you need to unlock the device’s bootloader as well. So keeping these points in mind, let’s get started. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

Install Android SDK

install adb platform tools windows

First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.

Download OnePlus 9/Pro Firmware

Now download your device’s stock firmware from the OnePlus official page. Once downloaded, extract it to any convenient location. You shall get a couple of files, including the payload.bin, which we will be using now to unbrick your OnePlus 9/Pro device via Fastboot Commands. So download it and move over to the next section

Convert OnePlus 9/Pro payload.bin to Fastboot ROM

Once you have got hold of the payload.bin file, it’s time to convert it to Fastboot and get the IMG files which could be flashed to their respective partitions. So please refer to our guide to How to Extract payload.bin and get Fastboot ROM Files.

Transfer OnePlus 9/Pro Fastboot ROM Files to ADB Directory

Once you have got all the Fastboot files, transfer them to the platform-tools folder. Furthermore, as you would have noticed from the above two images, the pariton schemes and ROM files are the same for both the OnePlus 9 (first image) and its Pro variant (second image). Therefore, the below fastboot commands to unbrick your device are applicable for both OnePlus 9 and 9 Pro.

Boot OnePlus 9/Pro to Fastboot Mode

Next up, you will have to boot your device to Fastboot Mode. Here’s how it could be done:


  1. If your device is in a bricked state, then power it off.
  2. Then press and hold the Power and Volume Keys together.
  3. Keeping both these keys pressed, connect your device to the PC via USB cable.

On the other hand, if you have a perfectly working device, then you may boot to Fastboot via the adb reboot bootloader command (after enabling USB Debugging) or using your device’s Advanced Power menu.

Unbrick OnePlus 9/Pro via Fastboot Commands

  1. Head over to the platform-tools folder, type in CMD in the address bar, and hit Enter. This will launch the Command Prompt.
  2. Now type in the below command to completely wipe your device (this is a must in case of a bricked device)
    fastboot -w
  3. After that, begin typing in the following commands in the CMD window, one at a time:
    fastboot flash boot boot.img
    fastboot flash cpucp cpucp.img
    fastboot flash dtbo dtbo.img
    fastboot flash modem modem.img
    fastboot flash oplusstanvbk oplusstanvbk.img
    fastboot flash oplus_sec oplus_sec.img
    fastboot flash qweslicstore qweslicstore.img
    fastboot flash shrm shrm.img
    fastboot flash splash splash.img
    fastboot flash vbmeta vbmeta.img
    fastboot flash vbmeta_vendor vbmeta_vendor.img
    fastboot flash vbmeta_system vbmeta_system.img
    fastboot flash vendor_boot vendor_boot.img
    fastboot flash vm-bootsys vm-bootsys.img
  4. With this, we have flashed half the files, the other half would have to be flashed in the FastbootD Mode. So use the below commands to boot your OnePlus 9 to FastbootD Mode:
    fastboot reboot fastboot
  5. Your device will now be booted to FastbootD. You may now flash the other files, one at a time, using the below commands:
    fastboot flash abl abl.img
    fastboot flash aop aop.img
    fastboot flash bluetooth bluetooth.img
    fastboot flash devcfg devcfg.img
    fastboot flash dsp dsp.img
    fastboot flash featenabler featenabler.img
    fastboot flash hyp hyp.img
    fastboot flash imagefv imagefv.img
    fastboot flash keymaster keymaster.img
    fastboot flash multiimgoem multiimgoem.img
    fastboot flash qupfw qupfw.img
    fastboot flash tz tz.img
    fastboot flash uefisecapp uefisecapp.img
    fastboot flash xbl xbl.img
    fastboot flash xbl_config xbl_config.img
    fastboot flash product product.img
    fastboot flash system system.img
    fastboot flash system_ext system_ext.img
    fastboot flash vendor vendor.img
    fastboot flash odm odm.img
  6. Once that is done, you will have to reboot the device back to Fastboot Mode from the current FastbootD Mode. Use the below command for that:
    fastboot reboot bootloader
  7. Finally, you may now reboot the device to the OS via the following command:
    fastboot reboot

That’s it. These were the steps to unbrick your OnePlus 9/Pro via Fastboot Commands. If you have any queries concerning the aforementioned steps, do let us know in the comments. We will get back to you with a solution at the earliest.

If your OnePlus 9/Pro device is running Android 12, then you could refer to the below-linked guide. It could come in handy if you wish to fix bootloop/softbrick or manually update to Android 12. As before, make sure to take a complete device backup beforehand: Flash Android 12 on OnePlus 9 Pro via Fastboot Commands.

Method 2: Unbrick OnePlus 9/Pro via Fastboot Enhance

This is a tool created by XDA Senior Member xzr467706992 and beholds a slew of intriguing features, including the ability to directly flash the payload.bin file, without the need to even manually extract it first. Do note that even though this tool was created for OnePlus 8T but it should work across other OnePlus devices too. [Well, I have personally tested it on OnePlus 7T and OnePlus 10 Pro, it works well and good even on those devices].

STEP 1: Download Fastboot Enhance Tool

Download the Fastboot Enhance Tool from GitHub [direct link]. Once downloaded, extract it to any convenient location on your PC. The biggest advantage of this tool is that you could directory flash the payload.bin file, there is no need to extract it and get the resultant IMG files!

STEP 4: Install Fastboot Drivers

The tool doesn’t come with the Fastboot Drivers, so you will manually have to install it on your PC. For that, please refer to our guide on How to Install Fastboot Drivers in Windows 11. Likewise, make sure to install the OnePlus USB Drivers as well [they are usually automatically installed as soon as you connect your device to the Windows PC for the first time].

STEP 5: Boot to Fastboot Mode

  1. Since your device is currently in a brick state, you wouldn’t be able to use the adb reboot bootloader command to boot your device to Fastboot Mode. Rather, you will have to take the help of the Hardware key combinations to get this job done.

  1. After doing the 4th step = “fastboot reboot fastboot” the devices is unresponsive… nothing happens, nothing loads and so I can’t continue. Please help.

      1. I installed the ADB Bootloader drivers but I still can not acces fastbootD. I have a oneplus 9 pro… when trying to get into fastbootD the phone turns black and nothing happens. after a while the cmd says “Failed to boot into userspace fastboot; one or more components might be unbootable.”

  2. After executing fastboot reboot fastboot I was hardbricked and had to MSM twice. On OOS11. There might be some error in this article… I recommend using MSM when you are in the position of having to follow this article.
