How to Use Extra-Tools SPD Diag Tool v1.0 — Step by Step
Using this tool is straightforward, but you need to follow each step carefully to avoid bricking your device. Here is the complete procedure I follow every time I work with SPD Diag Tool v1.0:
Download and Extract the Tool
Click the download button above and save the ZIP file to your PC. Right-click and extract it using WinRAR or 7-Zip to a folder on your desktop. No installation needed — it is a portable tool.
Install SPD USB Driver
If you have not already installed the Spreadtrum USB driver, download and install it first. This is critical — without the driver, your computer will not recognize the device when connected.
Enable USB Debugging
On your phone, go to Settings → About Phone → tap Build Number 7 times to unlock Developer Options. Then go to Developer Options and enable USB Debugging.
Launch the Tool
Open the extracted folder and run Extra-Tools SPD Diag Tool v1.0.exe as Administrator (right-click → Run as Administrator). This ensures the tool has full access to USB ports.
Connect Your Device
Power off your phone completely. Hold the Volume Down key and connect it to your PC using a good quality USB cable. The tool should detect the device and show its info in the main window.
Perform Your Desired Action
Now select the operation you want — Diag Enable, IMEI Repair, FRP Bypass, or Firmware Flash. Click the Start button and wait for the process to complete. Do not disconnect the phone until you see the green "Done" message.
Common Issues & Fixes While Using SPD Diag Tool v1.0
Even though SPD Diag Tool v1.0 works smoothly most of the time, you might run into a few hiccups. Here are the most common problems and their solutions:
- Tool not detecting device: Reinstall the SPD USB Driver and try a different USB cable. Also, make sure you are using a USB 2.0 port instead of USB 3.0.
- Phone stuck in Diag Mode: Simply hold the Power button for 10 seconds to force restart the device.
- "Port not found" error: Open Device Manager and check if the SPD port appears under Ports (COM & LPT). If not, the driver is not installed correctly.
- Flash fails midway: This usually happens due to a faulty USB cable or low battery. Charge your phone above 50% and use the original cable.
- Antivirus blocks the tool: Temporarily disable Windows Defender or your antivirus before running the tool. Some security software flags tools like this as suspicious due to low-level hardware access.
