Tecno Spark CM KA9 Firmware (Flash File) Drivers, Tools & Guide
I suggest extracting the firmware to a simple folder path, such as C:FirmwareKA9. SP Flash Tool can sometimes have trouble locating the scatter file if the folder path contains spaces or special characters. It is a small thing, but it saves a frustrating few minutes of wondering why the tool is not loading the file.
The Tecno Spark CM KA9 firmware is built for the MediaTek MT6737T chipset, which means you must use SP Flash Tool and VCOM/MTK drivers for flashing. These are included in the prerequisites below. The stock firmware ships with Android 7.0 (Nougat), which determines the default apps, security features, and interface you will see after flashing. There are 3 firmware files available for the Tecno Spark CM KA9 on this page. Pick the one that matches your current Android version for the smoothest flash.
This page archives 3 firmware versions for the Tecno Spark CM KA9, covering multiple Android builds and security patch levels. As a Transsion Holdings brand, Tecno devices share similar chipset architectures and flashing procedures across the Spark CM lineup.
Your Tecno Spark CM KA9 firmware comes as a compressed ZIP file. Download and extract it using WinRAR or 7-Zip. Once extracted, open the folder and confirm it contains the scatter file before proceeding.
A full flash erases everything on the device: apps, accounts, photos, and settings. That is the point, it gives you a clean slate and resolves issues like screen locks, FRP prompts, dead boot states, sluggish performance, and connectivity problems.
Factory Reset Tecno Spark CM KA9 Without a PC
To factory reset the Tecno Spark CM KA9 without a computer, power off the device completely, then hold Volume Up and Power at the same time until the recovery menu appears.
A hard reset erases all data and restores Tecno Spark CM KA9 to its original factory state. This fixes most software problems, slow performance, app crashes, forgotten screen locks, and bootloops. If the issue persists after a factory reset, a full firmware flash using SP Flash Tool is covered in the following sections.
Remove FRP Lock on Tecno Spark CM KA9
The fastest way to bypass the FRP lock on the Tecno Spark CM KA9 is to use a free Android apps launcher that allows access to settings during the setup wizard. After flashing or performing a factory reset you may see a Google account lock (FRP). Our free Android apps launcher is the fastest way to get past it. This is also why I always recommend removing your Google account before flashing, it avoids this problem entirely.
Common Reasons to Reinstall Tecno Spark CM KA9 Firmware
The Tecno Spark CM KA9 uses a MediaTek chipset, and SP Flash Tool is the standard method for firmware recovery on MTK devices. Here is what flashing the stock firmware can help with:
- Restore the original Tecno stock ROM to keep your warranty valid.
- Unlock your device if it has been locked or disabled.
- Update to the latest Android version supported by your phone.
- Remove persistent malware or adware that survives a factory reset.
- Fix Wi-Fi, Bluetooth, or mobile data connectivity that stopped working after an update.
- Recover your device when it only boots into recovery mode.
- Recover from “Download DA FAIL” errors and Secure Boot authentication issues specific to the MediaTek chipset in your device.

How to Pick the Correct Tecno Spark CM KA9 Firmware
The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:
- Find Your Model Code: Go to Settings, then About Phone. The code should be “KA9”. If it is a different variant, do not use this firmware.
- Cross-Check the Chipset: The Spark CM KA9 uses MediaTek MT6737T. If your phone shows a different chipset in recovery mode, stop and find the correct firmware for your hardware.
- Note Your Current Build: Write down the build number shown in About Phone. This helps you compare versions and decide whether to upgrade or reflash the same version.
- Boot Into Recovery: Recovery mode (Volume Up + Power while off) is the safest way to double-check your model info before committing to a flash.
- Check Download Size: After downloading, verify the file size matches the table on this page. Corrupt or partial downloads are a common cause of flash failures.
Firmware Details for Tecno Spark CM KA9
Here is a quick overview of the official firmware specifications:
| Firmware Information | Details |

Which Firmware Version Should I Download?
This is the question I get asked most often in the comments, so I put together a simple guide. Find your situation in the table and go straight to the right file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V93, download this one. It is the latest Tecno Spark CM KA9 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 the next older version, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V93 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V93 failed with a flash error | Try the next older version instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V93, 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.
Download Tecno Spark CM KA9 Firmware
Download the official stock firmware for your Tecno Spark CM KA9 below. The latest available version is V93. After downloading, verify the file size matches the table above, a size mismatch usually means a partial or corrupt download, and flashing a corrupt file can cause more problems than it solves.
| Software Details | Download Link | Members Link |
|---|---|---|
|
File Name: Tecno_Spark_CM_KA9_MT6737T_V93_180421.zip Size: 2.3 GB | Download Link | Download Link2 |
| File Name: Tecno_Spark_CM_KA9_MT6737T_V93_180421.zip Size: 2.29 GB | Download Link | Download Link2 |
| File Name: Tecno Spark CM KA9 (KA9-H3721H-N-180421V93).7z Size: 1.8 GB | Download Link | Download Link2 |
Only download firmware that is fully compatible with your exact device model. See the firmware selection guide above if you are not sure.
Important: The Tecno Spark CM KA9 (KA9) should not be confused with other Spark CM variants that may have different chipsets or regional firmware. Even devices in the same Spark CM line can use completely different processors. Always verify your exact model code “KA9” in Settings > About Phone before downloading any firmware from this page.
- Confirm your exact model is KA9, check About Phone, not the marketing name on the box.
- Your device must have a MediaTek MT6737T chipset. Boot into recovery mode to verify if unsure.
- Only use files downloaded from this page. Third-party mirrors may serve modified or incomplete packages.
- Compare the file size against the download table. If it does not match, the download is likely corrupt or incomplete.
What You Need Before Flashing Tecno Spark CM KA9
Do not skip this section. Most failed Tecno flashes come from rushing through the preparation steps. The VCOM driver installation is essential for the Tecno Spark CM KA9 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.
- Save Your IMEI Numbers: Type *#06# in the phone dialer and note down both numbers. These are your device identifiers for the cellular network. If flashing wipes them, you will need the originals to write them back.
- Disconnect Google Accounts: Before you start anything, remove all Google accounts from the phone. Settings then Accounts then tap each Google account and remove it. This avoids the FRP verification screen that appears after flashing if accounts were still linked.
- Create a Backup: Copy your data to your computer or an SD card. Flashing replaces the entire software on the phone, which means all personal data, apps, and settings will be permanently deleted.
- Charge First: Get the battery above 50% before starting. The flashing process takes a few minutes and the first boot takes several more. A power failure during either stage can leave the device in a state that requires more advanced recovery.
- Prepare Your PC Connection: You need a Windows computer and a USB cable that supports data transfer. Test the cable first by connecting the phone normally, if it shows up in File Explorer, the cable is good.
- Install the Right Drivers:
Flashing Tecno Spark CM KA9 Firmware With SP Flash Tool
We are using SP Flash Tool for this. For older devices, I recommend trying SP Flash Tool v5.1924 first. The newer versions of SP Flash Tool require a DA (Download Agent) file that older firmware packages do not include, and that is what causes the “Auth” errors you may have seen. 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.
- Prepare the Flash Files:
- Go to the download section and grab the firmware package that matches your device.
- Unzip the file to a folder on your desktop. Avoid using folder names with non-English characters or spaces, the flash tool may not read them correctly.
- Confirm Driver Setup:
- The drivers listed in prerequisites need to be installed and working before you connect the phone. If you are not sure, reinstall them and restart your computer.
- 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:
- Click “Download” to kick off the firmware write.
- Hands off the phone and cable until the tool shows completion. Moving or disconnecting the device mid-flash is the most common cause of a bricked phone.
- Wait and Reboot:
- When you see the success message, disconnect the USB cable.
- Hold the power button to boot the phone. Give it a solid 5 to 8 minutes for the first startup, this is normal.
What Is Normal After a Tecno Spark CM KA9 Flash?
Here is what is completely normal after a successful flash:
- How to know the flash was successful: SP Flash Tool will show a green circle or checkmark when done. If you see that, the flash completed successfully.
- Dial *#06# immediately after setup to check your IMEI. Do this before you insert a SIM card. If it shows “unknown” or “null”, follow the IMEI repair guide below before doing anything else.
- 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.
- Battery percentage may seem inaccurate for the first day. The battery statistics are calibrated during normal use. Charge the phone fully once without interruption and the readings will stabilize.
- Notification sounds and ringtones will be back to factory defaults. Any custom tones you had set before will need to be re-downloaded and re-assigned in Settings.
- 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.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
What to Do if Tecno Spark CM KA9 Flash Fails
- Tecno Spark CM KA9 Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the KA9, 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 CM KA9 After Flashing?
A missing or unknown IMEI is one of the most common things I see after a MediaTek flash. It happens 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.

Questions About Tecno Spark CM KA9 Firmware
Q1: Will flashing erase my data?
A: Yes, flashing with SP Flash Tool restores the device to factory state, including Android 7.0 (Nougat) 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.
Q2: What should I do if I encounter an FRP lock after flashing?
A: Use our free Android apps launcher. FRP lock activates when a Google account was still signed in before flashing. This is why signing out of your Google account before flashing avoids this issue entirely.
Q3: 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.
Q4: Is this firmware compatible with other Tecno models?
A: No. This firmware is built specifically for the Tecno Spark CM KA9 running on the MediaTek MT6737T chipset. Even variants of the Spark CM with a different letter suffix can have a completely different chipset inside. Flashing the wrong firmware can leave your phone in a state that is very difficult to recover from. Always check your exact model number in Settings.
Q5: 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.
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: 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.
Q8: Can I use a Mac or Linux computer for this?
A: The tools and drivers referenced on this page are Windows-only. If you are on Mac or Linux, your best option is to use a Windows virtual machine, or borrow a Windows PC for the 10 minutes it takes to complete the flash.
