In this guide, we will show you the steps to unbrick your OnePlus 9R device via Fastboot Commands. The latest addition to the OnePlus family managed to grab the attention of the masses. While its decision to ditch OxygenOS for Oppo’s ColorOS raised a few eyebrows, it still boasts some powerful specs sheet. Moreover, there exist three different devices in this lineup with the R variant being the most budget-friendly.
What else is commendable is the fact that these devices are among the most popular names in custom development. Be it for flashing custom ROMs or recoveries or gaining administrative access by rooting your device via Magisk, there’s a lot to try out. This will then allow you to flash mods such as Xposed, Magisk Modules, Viper4Android, Substratum Themes, among others. However, this is just one side of the coin. Carrying out these tweaks do bring in a few risks.
If you flash an incorrect binary or flash the correct one to the incorrect partition, then you are inviting trouble. In most cases, your device might end up in a bootloop or bricked state. Fortunately, there’s a handy way out. You could easily unbrick your OnePlus 9R by flashing the stock firmware via Fastboot Commands. And in this guide, we will show you how to do just that. So without any further ado, let’s get started.

The below instructions are listed under separate sections for ease of understanding. Make sure to follow in the exact same sequence as mentioned. Moreover, these instructions could also be used if you have a perfectly working device and just wish to revert to stock.
But in those cases, then you need to unlock the device’s bootloader. 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.
STEP 1: Install Android SDK
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.
STEP 2: Download OnePlus 9R 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 9R device via Fastboot Commands. So download it and move over to the next section.
STEP 3: Extract OnePlus 9R Payload.bin File
Once you have got hold of the payload.bin file, it’s time to extract it and get the partition IMG files. These files will then be flashed to their respective partitions. So please refer to our guide on How to Extract payload.bin and get Fastboot ROM Files.
