Tecno Spark Slim KM7k Firmware (Flash File) Drivers, Tools & Guide

This guide provides the stock ROM files, drivers, and instructions to restore your Tecno Spark Slim KM7k to factory settings.

I have worked on Tecno phones for a while now, and the Tecno Spark Slim KM7k comes in regularly, most often with FRP locks, bootloop issues, or stuck on the Tecno logo. This guide covers all of it. I have put everything you need in one place: the firmware, the tools, and the exact process I use myself.

One thing I always recommend before you start: extract the firmware to a simple folder path, something like C:FirmwareKM7k. 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 Slim KM7k is a relatively recent device (released 2025), so you should expect active firmware updates and good driver support on modern Windows systems. The Tecno Spark Slim KM7k runs on a MediaTek MT6789 Helio G99 chipset, which means you will use SP Flash Tool and VCOM/MTK drivers for flashing. These are included in the prerequisites below. There are 3 firmware files available for the Tecno Spark Slim KM7k on this page. Pick the one that matches your current Android version for the smoothest flash.

We verified firmware file integrity across 2 independent sources to confirm these are authentic, unmodified stock ROMs. As a Transsion Holdings brand, Tecno devices share similar chipset architectures and flashing procedures across the Spark Slim lineup.

Your Tecno Spark Slim KM7k 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.

This process restores the phone to its original factory state, which means all your personal data will be lost. That clean wipe is exactly what fixes persistent problems like bootloops, forgotten locks, Google account verification, battery drain, and system errors.

Bypass Google Lock on Tecno Spark Slim KM7k

The fastest way to bypass FRP on Tecno Spark Slim KM7k is to use a free Android apps launcher that lets you access 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.

Hard Reset Tecno Spark Slim KM7k

To factory reset Tecno Spark Slim KM7k without a computer, power off the device completely, then hold Volume Up and Power at the same time until the recovery menu appears. Use the volume keys to navigate to “Wipe Data/Factory Reset” and confirm with the Power button.

A hard reset erases all data and restores Tecno Spark Slim KM7k 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.

Verify Your Tecno Spark Slim KM7k Model Before Downloading

The most common mistake people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:

1. Open About Phone: Your device model must read “KM7k” exactly. Even small differences in the code can mean a completely different chipset and partition layout.
2. Verify the Chipset Type: This firmware targets MediaTek MT6789 Helio G99 specifically. Flashing it on a different chipset will fail or could brick the device.
3. Check Your Current Firmware Version: Compare your build number with the versions listed in the download section to decide which file to use.
4. Use Recovery Mode: If you cannot access Settings (phone is stuck or locked), boot into recovery mode to read the build and chipset details from the screen.
5. Regional Compatibility: Some Tecno firmware packages target specific regions. Confirm the download matches your device origin.

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	V716, download this one. It is the latest Tecno Spark Slim KM7k 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 15.1.2.107SP02(OP001PF001AZ), sometimes the latest OTA introduces new bugs and an older build runs better.
IMEI missing after a previous flash	Re-flash V716 first, then follow the IMEI repair guide. Do not skip the reflash.
V716 failed with a flash error	Try 15.1.2.107SP02(OP001PF001AZ) instead and double-check your scatter file selection before assuming the firmware is the problem.
Restoring to factory / warranty repair	V716, 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.

Tecno Spark Slim KM7k Flash Setup Checklist

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 Slim KM7k 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.

1. Back Up IMEI Numbers: Dial *#06# and write down both IMEI numbers now. You will need these if you need to restore your IMEI after flashing.
2. Remove Google Accounts: Sign out of all Google accounts to prevent FRP lock after flashing.
3. Back Up Your Data: Back up everything, photos, contacts, WhatsApp chats, important files. Flashing wipes the device completely.
4. Charge Your Device: At least 50% battery. A device that powers off during a flash is very difficult to recover.
5. USB Cable & PC: Use a proper data USB cable, not a charge-only cable, and a Windows computer with available USB ports.
6. Install Required Drivers:
   • VCOM Drivers
   • Tecno USB Drivers

Install Stock Firmware on Tecno Spark Slim KM7k

We use SP Flash Tool for Windows or SP Flash Tool for Linux for this. On this generation of Tecno devices, SP Flash Tool will almost certainly ask for a Download Agent (DA) auth file, that is normal for post-2023 MTK devices with DAA+SLA enabled. MTK Client is the tool I recommend here, it bypasses the auth requirement automatically without needing any leaked files. Load the scatter in MTK Client, connect the powered-off device, and it handles the rest. The complete SP Flash Tool guide is also available if you need more detail.

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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 to Do if Tecno Spark Slim KM7k Flash Fails

1. Tecno Spark Slim KM7k Not Recognized by SP Flash Tool:
   • In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the KM7k, 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.
2. 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.
3. 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.
4. “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.
5. 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.
6. 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.

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 show a green circle or checkmark when done. If you see that, the flash completed successfully.
• 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.
• Stuck in a bootloop after first boot? Enter recovery mode and do a factory reset from there, see the hard reset guide above. This can happen occasionally and does not mean the firmware is wrong.
• Wi-Fi, Bluetooth, and mobile data should all work right after setup. If mobile data is not connecting, go to Settings, SIM and Network, and re-enter your APN manually, the flash sometimes clears carrier APN 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.
• All your apps are gone, this is expected. Reinstall them from the Play Store. If you had a Google account backup active, it will offer to restore your apps automatically during setup.
• 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.

Missing IMEI or Corrupt Baseband on Tecno Spark Slim KM7k 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:

1. 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.
2. 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.
3. 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.
4. 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 Slim KM7k Firmware

Q1: Is this firmware compatible with other Tecno models?
A: No. This firmware is built specifically for the Tecno Spark Slim KM7k running on the MediaTek MT6789 Helio G99 chipset. Even variants of the Spark Slim 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.

Q2: Will flashing erase my data?
A: Yes, flashing with SP Flash Tool restores the device to factory state, including Android 15, HIOS 15 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.

Q3: 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.

Q4: 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.

Q5: 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.

Q6: 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.

Q7: 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.

Q8: 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.
