Choosing the Right Firmware Version

Selecting the correct firmware is critical before you start the flashing process. Follow these steps carefully to ensure compatibility and avoid potential issues with your device:

1. Identify Your Device Model: Navigate to “Settings” > “About Phone” on your device and confirm the model is listed as Tecno Spark 20 KJ5S.
2. Verify the Build Number: Check the build number details in “About Phone” for identifiers like “KJ5S” to match the firmware.
3. Confirm the Chipset: Based on official Tecno specifications, the Spark 20 KJ5S uses a Mediatek MT6769Z Helio G85 (12 nm) chipset with an Octa-core CPU (2×2.0 GHz Cortex-A75 & 6×1.8 GHz Cortex-A55) and Mali-G52 MC2 GPU. Ensure the firmware matches this platform.
4. Match the Firmware Version: Double-check that the firmware version number and any regional details align with your device’s current software specifications to prevent compatibility problems.
5. If you’re uncertain about your chipset or firmware version, restarting your device into recovery mode can display additional hardware and software details.

Prerequisites: What You Need Before Flashing

Before you start the firmware flashing process for your Tecno Spark 20 KJ5S, make sure you have prepared the following items and completed these essential steps:

1. Backup IMEI Numbers: Carefully note down and securely save your Tecno Spark 20 KJ5S’s IMEI numbers before you begin flashing.
2. Remove Google Accounts: Sign out of all Google accounts currently logged into your phone. This helps prevent FRP lock complications after the firmware installation.
3. Backup Your Data: Crucially, back up all important personal data. This includes contacts, messages, accounts, music, videos, and photos, as the flashing process will completely erase the device’s internal storage.
4. Charge Your Device: Ensure your phone has at least a 50% battery charge to prevent it from shutting down unexpectedly during the flashing procedure.
5. USB Cable & PC: You’ll need a reliable USB data cable and a Windows computer with functioning USB ports.
6. Install Necessary Drivers: Download and correctly install the following drivers on your PC:
   • VCOM Drivers (Essential for MediaTek device detection)
   • Tecno USB Drivers (Specific drivers for your device)
7. Reiterate Data Backup: Always double-check that your important data is backed up safely elsewhere to avoid permanent loss during the flashing.

How to Install Stock Firmware on Tecno Spark 20 KJ5S

You can flash the firmware using the widely-used SP Flash Tool. For devices with Secure Boot (SLA/DAA protection), you might need a specific Download Agent file. If a DA file for this model isn’t readily available, consider using the MTK Client tool as an alternative. Follow these steps carefully when using the MediaTek (MTK) SP Flash Tool:

1. Download and Extract Firmware:
   • Download the correct firmware package for your Spark 20 KJ5S.
   • Extract the contents of the downloaded ZIP file into a clearly named folder on your computer.
2. Install Required Drivers:
   • Confirm that both the VCOM Drivers and the Tecno USB Drivers are properly installed on your Windows PC.
3. Launch SP Flash Tool: Open the SP Flash Tool application on your computer. If you haven’t installed it yet, download the latest version suitable for your operating system: SP Flash Tool for Windows or SP Flash Tool for Linux. For detailed guidance, refer to our complete step-by-step SP Flash Tool flashing guide.
4. Load the Scatter File:
   • Inside the SP Flash Tool, click the “Scatter-loading” button.
   • Browse to the folder where you extracted the firmware 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 KJ5S.
   • Connect your turned-off phone to your PC using the USB cable. The SP Flash Tool should detect the device automatically (you might hear the Windows connection sound).
6. Start the 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 installing the firmware.
   • Important: Do not disconnect the USB cable or interrupt the process until it’s fully completed.
7. Wait for Completion and Reboot:
   • The process might take several minutes. A green checkmark or “Download OK” message will appear in SP Flash Tool upon successful completion.
   • Safely disconnect your device from the PC.
   • Power on your Tecno Spark 20 KJ5S. The first boot after flashing might take longer than usual.

Troubleshooting: Missing IMEI or Corrupt Baseband After Flashing?

Occasionally, after flashing firmware, you might find that the IMEI numbers are missing (showing as null or invalid) or the baseband is corrupted, leading to network connectivity issues. If this happens, follow these steps to restore them:

1. Install Correct Drivers: First, ensure that the necessary MediaTek (MTK) USB drivers are correctly installed so your PC can communicate properly with the phone in different modes.
2. Use an IMEI Repair Tool: Specialized tools are available for restoring IMEI on MediaTek devices. Popular options include the SN Write Tool or Maui Meta Tool. You can find tutorials on how to use the SN Write Tool or Maui Meta online.
3. Run the Repair Process:
   • Launch the chosen IMEI repair tool.
   • Connect your device to the computer (the connection method might vary depending on the tool; often it involves connecting the phone while powered off or in a specific mode).
   • Enter your original IMEI numbers (which you backed up earlier) into the appropriate fields for SIM 1 and SIM 2.
   • Follow the tool’s instructions to start the writing or repair process.
4. Restart and Verify: Once the tool indicates the process is complete, disconnect your phone and reboot it. After it starts up, open the dialer app and enter *#06# to check if your IMEI numbers have been successfully restored.

Common Issues and Quick Solutions During Flashing

1. Device Not Recognized by PC:
   • Confirm that all required USB drivers (VCOM and Tecno specific) are installed correctly. Reinstall them if necessary.
   • Try using a different USB cable (preferably the original one) and connect to a different USB port on your computer (avoid hubs).
   • Restart both your phone and your PC.
2. Boot Loop After Flashing:
   • If your device gets stuck in a continuous reboot cycle after flashing, boot it into recovery mode (usually by holding Volume Up + Power).
   • In recovery mode, navigate using volume keys and select “Wipe data/factory reset” using the power button. Confirm the action. This will erase user data but often resolves boot loops caused by conflicting data.
3. Flashing Errors in SP Flash Tool:
   • Double-check that you have downloaded the exact firmware version for your Tecno Spark 20 KJ5S model and region.
   • 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 run it as an administrator.
