In this all-encompassing manual, we shall elucidate the meticulous step-by-step process to resolve the vexing issues of auto brightness and screen flicker that plague your own OnePlus 11R. Should you desire an economical device with impressive features, the OnePlus 11R from the esteemed Chinese OEM is the perfect choice. Nonetheless, a subset of tech enthusiasts have come across certain complications.

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

Step 1: Install the Android SDK

The first and foremost step involves installing the Android SDK Platform Tools on your PC. These tools, officially provided by Google, include the 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: Enable USB Debugging and OEM Unlocking

Next, you must enable 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 to unlock the device’s bootloader.

To enable these options, go to Settings > About Phone > Tap on Build Number 7 times. Return to Settings > System > Advanced > Developer Options > Enable USB debugging and OEM unlocking.

Step 3: Unlock the Bootloader on the OnePlus 11R

To proceed further, you must unlock the bootloader of your OnePlus 11R. Remember 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 the bootloader on the OnePlus 11R.

Step 4: Download the OnePlus 11R Firmware

Download and extract the firmware version CPH2449 GLO A.10 from your PC.

Step 5: Boot the OnePlus 11R into 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 from the stock ROM, then click Open. Checkmark the “Ignore Unknown Partitions” option.

Go to the Fastboot Virtualization tab and click “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.

Step 7: Flash OCDT on the OnePlus 11R

1. Start by obtaining the code.img [CPH2449.img] from this source. Rename the file to ocdt.img and transfer it to the platform-tools folder. Now, boot your device into Fastboot Mode using the following command:
   • adb reboot bootloader
2. Next, use the below command to flash the ocdt.img:
   • fastboot flash ocdt ocdt.img
3. Execute the command to boot your device into the OS:
   • fastboot reboot
4. Skip the setup and refrain from setting any PIN, pattern, or password. Allow the device to boot into the OS, and then you may proceed with your desired tasks.

Conclusion

In conclusion, these steps will resolve auto-brightness and screen flicker issues on your OnePlus 11R. However, be aware that some users have relocked the bootloader [via fastboot flashing lock] after performing these steps. Nevertheless, we advise against doing so, as it may lead to complications in the long run, mainly due to the unavailability of an unbrick tool.
