Which Firmware Version Should I Download?
This is the most frequent question I receive, so here’s a quick guide. Find your situation in the table and select the appropriate file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V652, download this one. It is the latest Tecno Spark 8C KG5j firmware available. |
| FRP / Google account lock only | See the FRP bypass guide above, you likely do not need the full firmware for this. |
| Phone slow after a recent OTA update | Try V644, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V652 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V652 failed with a flash error | Try V644 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V652, clean state, fresh start. |
My general approach with MTK devices: always try the latest version first. I have seen people spend a lot of time trying older builds when the newest one would have worked fine. Only move to an older version if the latest fails more than once, and make sure it is a driver issue you are solving, not a firmware issue.

Only download firmware fully compatible with your exact device model. See the firmware selection guide above if you are not sure.
Important: The Tecno Spark 8C KG5j (KG5j) should not be confused with other Spark 8C variants that may use different chipsets or regional firmware. Even devices in the same Spark 8C line can have completely different processors. Always verify your exact model code “KG5j” in Settings > About Phone before downloading any firmware from this page.
- Your model number is a variant of KG5j with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.
- Your chipset differs from MediaTek MT6761 Helio A22. Confirm in recovery mode before proceeding.
- You downloaded the file from a source other than this page.
- The file size differs significantly from the sizes listed in the table above, a size mismatch usually means a partial download, which will fail mid-flash.
Prerequisites for Tecno Spark 8C KG5j Firmware
Do not skip this section. Most failed Tecno flashes result from rushing through preparation steps. Installing the VCOM driver is essential for the Tecno Spark 8C KG5j and other MediaTek devices. Windows may show the device in Device Manager, and SP Flash Tool will still not detect it if the correct VCOM driver is not installed.
- Record IMEI Before Flashing: Dial *#06# and save both IMEI numbers somewhere safe, a screenshot works. If flashing corrupts the baseband, these numbers are what you will need to restore cellular connectivity.
- Unlink Google Accounts: Go to Settings, then Accounts, and remove all Google accounts. This prevents Factory Reset Protection from activating after the flash. It is the most frequently skipped step and causes the most post-flash issues.
- Full Data Backup: Flashing erases everything. Transfer your photos, contacts, app data, and important files to your computer or cloud backup before starting.
- Charge the Battery: Ensure at least 50% charge. A dead battery during a flash can corrupt the system partition and turn a fixable problem into a much bigger one.
- Windows PC and USB Cable: You will need a Windows computer and a data-capable USB cable. Cheap charge-only cables are the primary reason flash tools fail to detect devices.
- Driver Installation:
Install Stock Firmware on Tecno Spark 8C KG5j
We are using SP Flash Tool for this. For older devices, I recommend trying SP Flash Tool v5.1924 first. Newer versions of SP Flash Tool require a DA (Download Agent) file that older firmware packages do not include, causing “Auth” errors. If SP Flash Tool keeps asking for an auth file and you do not have one, switch to MTK Client, it handles Secure Boot automatically. Download SP Flash Tool for Windows or SP Flash Tool for Linux and follow the steps below. The complete SP Flash Tool guide is also available if you need more detail.
- Get the Firmware Ready:
- Download the firmware file from the download section above.
- Right-click the ZIP and select “Extract Here” or use 7-Zip. Put the extracted files in a folder without spaces in the name, like
C:firmware.
- Verify Your Drivers:
- Make sure the required drivers are installed. After installing, restart your PC, drivers often do not activate until after a reboot.
- Load the Firmware File:
- Click on the “Scatter-loading” button. Navigate to the folder where you extracted the firmware and select the “scatter.txt” file.
- Connect Your Device:
- Power off your phone completely, not sleep mode, fully off.
- Connect to your PC via USB cable. The flash tool will detect it automatically.
- Start Flashing:
- Hit the “Download” button in the flash tool to start the process.
- Leave the phone and cable completely alone until it finishes. Any interruption during this stage risks corrupting the flash.
- Wait and Reboot:
- When the flash completes, unplug the USB cable from your phone.
- Turn on the device. First boot takes 3 to 8 minutes, do not force restart it during this time.
What to Expect After Flashing
Here is what is completely normal after a successful flash:
- How to know the flash was successful: SP Flash Tool will display a green circle or checkmark when done. If you see that, the flash completed successfully.
- Notification sounds and ringtones will revert to factory defaults. Any custom tones you had set before will need to be re-downloaded and re-assigned in Settings.
- First boot takes 3 to 8 minutes, do not force-reboot the device. The operating system is setting itself up from scratch. Interrupting this is how devices end up in bootloops.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- Be careful when re-adding your Google account, if you did not remove it before flashing, you may see an FRP prompt. Add it fresh during the setup wizard, not afterwards through Settings.
- Storage will show almost full capacity available since all your apps and files are gone. The system partition size varies by firmware version but is typically 4 to 8 GB on most devices.
- Fingerprint and face unlock data are erased during the flash. You will need to re-register your fingerprints and face data from scratch in the security settings.
Troubleshooting Tecno Spark 8C KG5j Flash Errors
- Tecno Spark 8C KG5j Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the KG5j, restart your PC, and try again before changing anything else.
- If that does not work, switch to a USB 2.0 port, USB 3.0 ports can cause detection issues with MediaTek devices more often than people expect.
- Still not working? Temporarily disable your antivirus. It can block the VCOM driver from loading without giving you any error message.
- Boot Loop After Flashing:
- Enter recovery mode and perform a factory reset from there. Most post-flash bootloops on MediaTek are caused by conflicts with old cached data, a wipe from recovery usually fixes this without needing to reflash.
- Wrong Scatter File / Firmware Mismatch:
- If SP Flash Tool throws an error as soon as you try to start the download, check your scatter file first. A mismatch between the scatter file and your device build is one of the most common causes of flash errors.
- “Download DA FAIL” Error:
- This error comes up regularly. It almost always means the VCOM driver is not properly installed. Reinstall it, restart your PC, and try again. If that still does not work, try switching to SP Flash Tool v5.1924, older devices sometimes respond better to the older version.
- Error 8038 (BROM Error):
- The device is not entering BROM mode correctly. Power it off completely and, if possible, remove the battery for 30 seconds. Reconnect and try again. Some MediaTek devices require you to hold Volume Down while plugging in the USB cable to enter BROM mode.
- Auth File / Secure Boot Error in Newer SP Flash Tool:
- Newer versions of SP Flash Tool require a DA (Download Agent) authentication file for devices with Secure Boot enabled. If you do not have that file, switch to MTK Client instead, it handles Secure Boot automatically and is the simpler solution.
Missing IMEI or Corrupt Baseband on Tecno Spark 8C KG5j After Flashing?
A missing or unknown IMEI is one of the most common issues after a MediaTek flash. It occurs because the NVRAM partition, which stores your IMEI and calibration data, sometimes does not survive the flash intact. It looks alarming, but it is fixable. Here is what to do:
- Check your drivers first: Install the Mediatek CDC Driver if you have not already, without it, the IMEI repair tools will not detect your device. This is the step most people miss.
- Use SN Write Tool or Maui Meta: SN Write Tool is the first option I try, it is straightforward and works on most MTK devices. Maui Meta is the alternative if SN Write does not connect. You can learn more about using SN Write Tool here.
- Run the repair:
- Connect your device to the computer.
- Enter the original IMEI numbers for both SIM slots, these are the numbers you wrote down before flashing.
- Click “Start” and let it complete without interrupting the connection.
- Verify after reboot: Once done, reboot your phone and dial *#06#. Your IMEI numbers should be back. If they are still showing null, run the process again, sometimes the first attempt does not complete correctly.

Tecno Spark 8C KG5j Firmware FAQ
Q1: How do I enter recovery mode?
A: Power the device off completely, then hold Volume Up + Power at the same time until the recovery menu appears. The recovery menu displays the build number which you can use to verify your firmware version before flashing.
Q2: Is it safe to flash during a power outage risk?
A: It is best to avoid flashing during unstable power conditions. If your PC shuts down during the flash, it can corrupt the write and leave the phone in an unbootable state. If you are in an area with unreliable power, use a laptop with a fully charged battery instead of a desktop.
Q3: Do I need an internet connection during flashing?
A: No. The flashing process is entirely offline, it happens between your PC and the phone via the USB cable. You do not need internet at any point during the flash itself. You will need internet later to set up the phone and download your apps.
Q4: What if the flash fails halfway through?
A: Do not panic and do not disconnect the phone. Close SP Flash Tool, restart it, and try the flash again from the beginning. In most cases, a failed flash just means the process needs to be repeated. The device is usually still detectable by the flash tool even after a failed attempt.
Q5: Will flashing erase my data?
A: Yes, flashing with SP Flash Tool restores the device to factory state, including Android 11 (Go edition), HiOS 7.6 default settings. All apps, photos, contacts, and accounts will be removed. Back up everything you need before you start. There is no way to recover data once the flash is complete.
Q6: How long does the flashing process take?
A: The actual flash usually takes between 3 and 10 minutes depending on the firmware size and USB connection speed. The first boot after flashing takes another 3 to 8 minutes. Do not interrupt the device during either stage. If the progress bar in SP Flash Tool appears stuck, give it a few more minutes before assuming something went wrong.
Q7: My IMEI shows “unknown” after flashing. Is my phone permanently damaged?
A: No, it looks alarming, but it is fixable. Follow the IMEI repair guide in the troubleshooting section above. For MediaTek devices, SN Write Tool or Maui Meta will handle the repair. Do not insert a SIM card until the IMEI is restored.
Q8: My device is not detected by SP Flash Tool. What should I do?
A: Start with the drivers, reinstall the VCOM drivers, restart your PC, then try again. Switch to a USB 2.0 port if you are on USB 3.0. Disable your antivirus temporarily. If none of that works, leave a comment with the exact error message.

- If that does not work, switch to a USB 2.0 port, USB 3.0 ports can cause detection issues with MediaTek devices more often than people expect.
- Still not working? Temporarily disable your antivirus. It can block the VCOM driver from loading without giving you any error message.
- Boot Loop After Flashing:
- Enter recovery mode and perform a factory reset from there. Most post-flash bootloops on MediaTek are caused by conflicts with old cached data, a wipe from recovery usually fixes this without needing to reflash.
- Wrong Scatter File / Firmware Mismatch:
- If SP Flash Tool throws an error as soon as you try to start the download, check your scatter file first. A mismatch between the scatter file and your device build is one of the most common causes of flash errors.
- “Download DA FAIL” Error:
- This error comes up regularly. It almost always means the VCOM driver is not properly installed. Reinstall it, restart your PC, and try again. If that still does not work, try switching to SP Flash Tool v5.1924, older devices sometimes respond better to the older version.
- Error 8038 (BROM Error):
- The device is not entering BROM mode correctly. Power it off completely and, if possible, remove the battery for 30 seconds. Reconnect and try again. Some MediaTek devices require you to hold Volume Down while plugging in the USB cable to enter BROM mode.
- Auth File / Secure Boot Error in Newer SP Flash Tool:
- Newer versions of SP Flash Tool require a DA (Download Agent) authentication file for devices with Secure Boot enabled. If you do not have that file, switch to MTK Client instead, it handles Secure Boot automatically and is the simpler solution.
Missing IMEI or Corrupt Baseband on Tecno Spark 8C KG5j After Flashing?
A missing or unknown IMEI is one of the most common issues after a MediaTek flash. It occurs because the NVRAM partition, which stores your IMEI and calibration data, sometimes does not survive the flash intact. It looks alarming, but it is fixable. Here is what to do:
- Check your drivers first: Install the Mediatek CDC Driver if you have not already, without it, the IMEI repair tools will not detect your device. This is the step most people miss.
- Use SN Write Tool or Maui Meta: SN Write Tool is the first option I try, it is straightforward and works on most MTK devices. Maui Meta is the alternative if SN Write does not connect. You can learn more about using SN Write Tool here.
- Run the repair:
- Connect your device to the computer.
- Enter the original IMEI numbers for both SIM slots, these are the numbers you wrote down before flashing.
- Click “Start” and let it complete without interrupting the connection.
- Verify after reboot: Once done, reboot your phone and dial *#06#. Your IMEI numbers should be back. If they are still showing null, run the process again, sometimes the first attempt does not complete correctly.

Tecno Spark 8C KG5j Firmware FAQ
Q1: How do I enter recovery mode?
A: Power the device off completely, then hold Volume Up + Power at the same time until the recovery menu appears. The recovery menu displays the build number which you can use to verify your firmware version before flashing.
Q2: Is it safe to flash during a power outage risk?
A: It is best to avoid flashing during unstable power conditions. If your PC shuts down during the flash, it can corrupt the write and leave the phone in an unbootable state. If you are in an area with unreliable power, use a laptop with a fully charged battery instead of a desktop.
Q3: Do I need an internet connection during flashing?
A: No. The flashing process is entirely offline, it happens between your PC and the phone via the USB cable. You do not need internet at any point during the flash itself. You will need internet later to set up the phone and download your apps.
Q4: What if the flash fails halfway through?
A: Do not panic and do not disconnect the phone. Close SP Flash Tool, restart it, and try the flash again from the beginning. In most cases, a failed flash just means the process needs to be repeated. The device is usually still detectable by the flash tool even after a failed attempt.
Q5: Will flashing erase my data?
A: Yes, flashing with SP Flash Tool restores the device to factory state, including Android 11 (Go edition), HiOS 7.6 default settings. All apps, photos, contacts, and accounts will be removed. Back up everything you need before you start. There is no way to recover data once the flash is complete.
Q6: How long does the flashing process take?
A: The actual flash usually takes between 3 and 10 minutes depending on the firmware size and USB connection speed. The first boot after flashing takes another 3 to 8 minutes. Do not interrupt the device during either stage. If the progress bar in SP Flash Tool appears stuck, give it a few more minutes before assuming something went wrong.
Q7: My IMEI shows “unknown” after flashing. Is my phone permanently damaged?
A: No, it looks alarming, but it is fixable. Follow the IMEI repair guide in the troubleshooting section above. For MediaTek devices, SN Write Tool or Maui Meta will handle the repair. Do not insert a SIM card until the IMEI is restored.
Q8: My device is not detected by SP Flash Tool. What should I do?
A: Start with the drivers, reinstall the VCOM drivers, restart your PC, then try again. Switch to a USB 2.0 port if you are on USB 3.0. Disable your antivirus temporarily. If none of that works, leave a comment with the exact error message.
