Should you desire an economical device abundant with an array of impressive features, the OnePlus 11R from the esteemed Chinese OEM presents itself as the perfect choice. Nonetheless, a subset of tech enthusiasts has come across certain complications.

Aside from the perplexing MSM Tool debacle, there exists another maddening predicament, diligently documented by numerous users. Those who have seamlessly migrated their OnePlus 11R [Ace 2] from the ColorOS to the OxygenOS are persistently grappling with the conundrum of auto brightness fluctuations and irritating screen flickers. If you find yourself entrapped within a similar quagmire, this guide shall acquaint you with an ingenious workaround to rectify the irksome issues. Let us embark on this journey to unravel the solution together.

Step 1: Installing Android SDK

To begin with, the first and foremost step involves installing the Android SDK Platform Tools on your PC. These tools, officially provided by Google, include ADB and Fastboot binaries and are highly recommended. Download the SDK and extract it to a convenient location on your PC. This will give you the platform tools folder, which will be utilized throughout this guide.

Step 2: Enabling USB Debugging and OEM Unlocking

Next, you need to enable both USB Debugging and OEM Unlocking on your OnePlus 11R. USB Debugging allows your device to be recognized by the PC in ADB mode, enabling you to boot into Fastboot Mode. OEM Unlocking is necessary for unlocking the device’s bootloader.

To enable these options, go to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.

Step 3: Unlocking Bootloader on OnePlus 11R

Proceeding further, you must unlock the bootloader of your OnePlus 11R. Keep in mind that this process will erase all data and may void the device’s warranty. If you are comfortable with this, follow our comprehensive guide on How to Unlock Bootloader on OnePlus 11R.

Step 4: Downloading OnePlus 11R Firmware

Step 5: Booting OnePlus 11R to Fastboot Mode

  1. Connect your OnePlus 11R to the PC using a USB cable, ensuring that USB Debugging is still enabled. Now, open the platform-tools folder, type “CMD” in the address bar, and hit Enter to launch the Command Prompt.
  2. Type the following command in the CMD window to boot your device into Fastboot Mode:
    • adb reboot bootloader
  3. To verify the Fastboot connection, enter the command below and check if the device ID is displayed:
    • fastboot devices

Step 6: Flashing OnePlus 11R Firmware via Fastboot Enhance

First, download and extract Fastboot Enhance. Launch the application, head to Payload Dumper, and click on Browse. Locate and select the extracted payload.bin file of the stock ROM, then click Open. Checkmark the “Ignore Unknown Partitions” option.

Now, go to the Fastboot Virtualization tab and click on “Flash payload.bin.” After completion, click on the “Reboot to FastbootD” button, which will prompt your device to boot into FastbootD Mode. Once again, checkmark “Ignore Unknown Partitions” and proceed to flash the payload.bin.

    • adb reboot bootloader
  2. Next, use the below command to flash the ocdt.img:
    • fastboot flash ocdt ocdt.img
