Step-by-Step Guide to Unbrick OnePlus Ace 3 Pro Using MSM Tool
1. Download and Install the MSM Tool
Start by downloading the MSM Tool compatible with the OnePlus Ace 3 Pro. Once downloaded, extract the ZIP file to a folder on your PC.
2. Install Qualcomm USB Drivers
- Open Device Manager on your Windows PC.
- Right-click the Start Menu, then select Device Manager.
- Locate Unknown Device or OnePlus Ace 3 Pro under the “Ports” or “Other Devices” section.
- Right-click it, select Update Driver, and install Qualcomm USB drivers. You can download these from trusted sources like the Qualcomm website.
3. Boot OnePlus Ace 3 Pro into EDL (Emergency Download Mode)
The MSM Tool requires the device to be in EDL mode to proceed with flashing. Follow these steps:
- Power off the OnePlus Ace 3 Pro completely.
- Hold down the Volume Up button and connect the phone to the PC using a USB cable.
- Once connected, the device should enter EDL mode, and the MSM Tool should detect the phone automatically.
4. Launch the MSM Tool
- After successfully connecting the OnePlus Ace 3 Pro in EDL mode, open the MSM Tool you downloaded earlier.
- The tool should detect your connected device. If it’s not detected, verify that the Qualcomm drivers are correctly installed and try again.
5. Start the Unbricking Process
- In the MSM Tool interface, locate the Start or Download button and click it to initiate the flashing process.
- The tool will begin flashing the firmware to your OnePlus Ace 3 Pro. This process may take a few minutes, depending on your computer’s performance and the device itself.
6. Wait for the Process to Complete
- The MSM Tool will show a progress percentage during flashing.
- Do not disconnect your device during this process, as it may cause further software corruption.
7. Reboot the Device
- Once the MSM Tool confirms that the flashing is complete, safely disconnect your OnePlus Ace 3 Pro from the PC.
- Your device should now boot into the operating system, fully unbricked.
- If the device doesn’t boot immediately, allow a few minutes for initialization.
Troubleshooting Tips
- Device Not Entering EDL Mode?
