Downgrade OnePlus Nord CE from Android 12 to Android 11 via MSM Download Tool
MSM Download Tool is the software used by OnePlus service center employees to unbrick the devices. But due to some great work by the developers at XDA, this tool is now available for everyone to use. Using this tool, we will be flashing the Android 11 OFP firmware to your device. While it does not require an unlocked bootloader, still the process is quite technical and could result in a few issues if not done correctly. With that in mind, let’s get started.
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: Install Qualcomm USB Drivers
Next up, you will have to download and install the Qualcomm USB Drivers. This is needed so that your PC (and the MSM Tool) is able to identify the connected device in EDL Mode. So refer to our guide on Qualcomm HS-USB QDLoader 9008 Drivers: Download & Install
STEP 3: Download MSM Download Tool
Next up, get hold of the MSM Download Tool corresponding to your OnePlus device from this post [make sure to download the Android 11 firmware]. Once downloaded, extract it to any convenient location on your PC. This will give you the Tool as well as the OPS Firmware for your device.
STEP 4: Boot OnePlus to EDL Mode
you will now have to boot your OnePlus device to Emergency download mode. For that, please refer to our comprehensive tutorial on How to Boot any OnePlus Device to EDL Mode. Or you could also refer to the below shorter instructions. If your device is still being shown as QHUSB_BULK, then reverify driver installation, use USB 2.0 Port, or try using a different USB cable. Any one of these tweaks could fix the EDL connection error.
