4. Load the Scatter File:
   • Inside the SP Flash Tool interface, click the “Scatter-loading” button.
   • Browse to the folder where you extracted the firmware files and select the file named “MTxxxx_Android_scatter.txt” (the exact name might vary slightly).
5. Connect Your Device:
   • Completely power off your Tecno Spark 20 KJ5N.
   • Connect your phone to the PC using the USB cable. The SP Flash Tool should detect the device automatically (you might hear a connection sound).
6. Start Flashing Process:
   • Ensure the flashing mode is set to “Download Only” (usually the default).
   • Click the large “Download” button in the SP Flash Tool to begin flashing the firmware.
   • Important: Do not disconnect the USB cable or interrupt the process until it is fully complete.

   • The flashing process may take several minutes. A green checkmark or “Download OK” message will appear upon successful completion.
   • Safely disconnect your device from the PC.
   • Power on your Tecno Spark 20 KJ5N. The first boot after flashing might take longer than usual.

Missing IMEI or Corrupt Baseband After Flashing?

Occasionally, flashing firmware can lead to issues like a missing IMEI number or a corrupted baseband, affecting network connectivity. If you encounter this problem, follow these steps to restore them:

1. Install Correct Drivers: Double-check that you have the necessary MediaTek (MTK) drivers installed correctly so repair tools can detect your device.
2. Use an IMEI Repair Tool: Specialized tools are available for MediaTek devices. Popular options include the SN Write Tool or Maui Meta Tool. You can learn more about using the SN Write Tool or Maui Meta via online tutorials.
3. Run the Repair Process:
   • Launch the chosen IMEI repair tool on your computer.
   • Connect your Tecno Spark 20 KJ5N (often in a specific mode like Meta Mode for Maui Meta).
   • Carefully enter your original IMEI numbers (usually found on the device box or under the battery) for both SIM slots when prompted by the tool.
   • Follow the tool’s instructions to initiate the repair or “write” process.
4. Restart and Verify: Once the tool indicates completion, disconnect and reboot your phone. Check if the IMEI numbers are restored by dialing *#06# in the phone app.

Common Issues and Solutions During Flashing

1. Device Not Recognized by PC:
   • Verify that all required USB drivers (VCOM and Tecno specific) are correctly installed. Reinstall them if necessary.

   • If your device gets stuck in a continuous restarting loop after flashing, try booting into recovery mode (usually by holding Power + Volume Up).
   • Once in recovery mode, perform a “Wipe data/factory reset” and then reboot. Note this will erase user data.
3. Flashing Errors in SP Flash Tool:
   • Double-check that you have downloaded the correct firmware package specifically for the Tecno Spark 20 KJ5N model.
   • Ensure you selected the correct scatter file from the extracted firmware folder within the SP Flash Tool.
   • Try using a different version of the SP Flash Tool or running it as an administrator.
