These are instructions on how to install stock firmware (ROM) on the OnePlus 9R Smartphone.
Note: The following method will only work on the OnePlus 9R Smartphones with Unlocked Bootloader. If your device bootloader is in a locked state, unlock it first and follow the procedure below.
Caution: The OnePlus 9R Smartphone powered by Qualcomm SM8250-AC Snapdragon 870 5G Chipset, runs on Android 11 (OxygenOS 22.214.171.124). Flashing or installing the Stock Firmware will wipe/delete the data from the Smartphone. Therefore, we recommend you take a backup of your data before following the tutorial below.
Congratulations! Your OnePlus 9R Smartphone will now boot into the OxygenOS.
[*] If you’re running on any custom ROM, you can use the above method to re-install the OxygenOS on the device. However, you can not use the above method to Upgrade or Downgrade the device.
[*] You can not use the above method to Switch from ColorOS to OxygenOS. Instead, use MSM Unbrick Tool, to Switch from ColorOS to OxygenOS.
[*] Important: Before flashing, ensure you know which type of RAM your device supports, i.e. LPDDR4X or LPDDR5, as flashing the wrong xbl config will hard brick the device. You can check the RAM variant using the following ADB command:
adb shell getprop ro.boot.ddr_type
If the value is 0, then the variant you have is LPDDR4X. If the value is 1, then the variant is LPDDR5.
