Title:
📱 How to Use Spreadtrum IMEI Tool v41 – Write/Repair IMEI on Unisoc/Spreadtrum Devices (Proper Guide)

Post Content:

If you’re working with Unisoc (formerly Spreadtrum) smartphones — especially models like Infinix, Tecno, Itel, or certain Chinese tablets — you may have run into the dreaded “Invalid IMEI” or “Null IMEI” issue after flashing firmware.

The Spreadtrum IMEI Tool v41 is one of the most reliable free tools to rewrite IMEI numbers on Spreadtrum SC77xx, SC98xx, and Unisoc Tiger series chips.

👇 Here’s a clean, working guide.

Precautions:

Part 8: Future Outlook – Will v41 Be Surpassed?

Spreadtrum (now Unisoc) continues to update its chipsets. Android 13/14 introduces new security layers: signed IMEI partitions that reject writes from any non-authorized tool. Already, on devices like the Unisoc T760 (Samsung A14), v41 fails with "Access Denied 0xC000".

What will eventually be better than v41?

Until then, for all chipsets released before 2023, Spreadtrum IMEI Tool v41 remains the definitive, free, and reliable solution.

Phase 2: Loading Databases

  1. Launch SPD_IMEI_Tool_v41.exe. The interface now features a "Dark Mode" option (a minor aesthetic win, but appreciated for long repair hours).
  2. Click "Load Database." Navigate to your firmware folder.
  3. Here is the "Better" moment: Unlike v40 that required separate loading, v41 scans for *.db and *.pac files simultaneously. Select the correct MPDB_*.bin file.
  4. The tool validates the checksum instantly. If the database is corrupted, v41 tells you which byte is wrong—a debugging feature previously only seen in professional boxes like the Miracle Box.

Steps:

  1. Install Drivers
    Run SPD_Driver_Installer_v2.2.exe (included with v41 archive). Restart your PC if prompted.

  2. Prepare the Phone
    Power off the phone. Launch the SPD Upgrade Tool or use a Factory Coder short test point to force the device into Diagnostic Mode (usually holding Volume Up while connecting USB).

  3. Open Spreadtrum IMEI Tool v41
    Run as Administrator (critical for direct hardware access). The interface loads with a green "Ready" indicator.

  4. Connect Phone
    With the phone off, connect the USB cable. The tool should detect the COM port automatically (e.g., COM5 Spreadtrum USB DIAG). If not, click "Refresh Port".

  5. Enter IMEI
    Type or paste IMEI1 and IMEI2. The tool validates length (15 digits) and rejects invalid ones.

  6. Write IMEI
    Click "Write IMEI". The progress bar completes in 3-5 seconds. A dialog says: "IMEI Writing Successful – Verified."

  7. Verify
    Disconnect the phone. Power it on normally. Dial *#06#. Both IMEI numbers should appear. Reboot again to double-check persistence.
