Q1. Why would I downgrade my OnePlus 10T from Android 12 to Android 11?

Many users found early releases of OxygenOS 12 to have bugs, reduced battery life, or UI changes they disliked. Downgrading to a stable OxygenOS 11 build is a common way to restore a preferred and more reliable user experience.

Q2. My phone is completely dead (hard bricked). Can this guide help?

Yes. As long as your PC can detect the phone in EDL Mode (as "Qualcomm HS-USB QDLoader 9008"), the MSM Download Tool can rewrite the entire system from a low level and bring your phone back to life.

Q3. What is the difference between the "export" and "QPST" files?

They are just different ways the same firmware has been packaged by various sources. As long as the build number (e.g., A.10) and model (CPH2413) are the same, they contain the same official OnePlus software and will work with the MSM tool.

OnePlus 10T 5G Stock ROM (Firmware)

The OnePlus 10T 5G (CPH2413) is a flagship-tier smartphone known for its incredible performance, powered by the Snapdragon 8+ Gen 1 chipset, and its industry-leading 150W SUPERVOOC charging. While the device launched with Android 12, many users experienced bugs, battery drain, or preferred the user interface of the previous Android 11 (OxygenOS 11). This guide provides a collection of official Android 11 firmware packages. These files are essential tools for users who wish to **downgrade from Android 12 to 11**, or for those who need to unbrick a dead phone using the powerful MSM Download Tool.

⚠️ CRUCIAL WARNING: Unbrick Tool & Downgrade Risk
This process uses the MSM Download Tool, a powerful, low-level flashing utility for Qualcomm devices. It is the official method to unbrick a OnePlus phone. This will completely erase all your personal data and will re-lock the bootloader. Downgrading major OS versions always carries risks. Proceed with extreme caution.

🔧 Device Troubleshooting

MSM Tool is stuck on “Waiting for device”: This is a driver issue. Ensure you have correctly installed the Qualcomm HS-USB QDLoader drivers. You may need to disable “Driver Signature Enforcement” in Windows. Verify the phone is in EDL mode and that it appears as “Qualcomm QDLoader 9008” in your PC’s Device Manager.
The flash fails with a Sahara or Firehose error: This indicates a communication problem. Use a different USB 2.0 port on your computer (avoid hubs), use the original red OnePlus cable, and make sure to run the MSM tool as an administrator.
After downgrading, I’m not receiving new OTA updates: This is normal. After a full downgrade/unbrick with the MSM tool, you may need to manually download and install the first subsequent OTA update from the OnePlus website before the automatic update system will function again.
