Tecno Camon CX Firmware (Flash File) Drivers, Tools & Guide
Tecno phones come into my workshop often with FRP locks, bootloops, 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:FirmwareCX. 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.
There are 2 firmware files available for the Tecno Camon CX on this page. Pick the one that matches your current Android version for the smoothest flash. The stock firmware ships with Android 7.0 (Nougat) with HiOS, which determines the default apps, security features, and interface you will see after flashing. The Tecno Camon CX was originally released in 2017, which means USB driver compatibility on newer Windows versions (10/11) may require manual installation rather than plug-and-play.
Transsion Holdings devices share similar chipset architectures and flashing procedures across the Camon CX lineup. The Tecno Camon CX was released in 2017. This page is maintained with the latest available firmware builds as they become available.
Your Tecno Camon CX 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.
Once you flash, the device goes back to factory condition. Everything stored on the phone, photos, messages, apps, will be gone. This clean state is what allows the flash to fix stuck logos, FRP locks, software corruption, and performance issues.
Tecno Camon CX Hard Reset Guide
To factory reset Tecno Camon CX 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 Camon CX 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.
FRP Removal for Tecno Camon CX
The fastest way to bypass FRP on Tecno Camon CX 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.
What Tecno Camon CX Firmware Fixes
Flashing the stock firmware can help with system restoration and performance issues on the Tecno Camon CX. SP Flash Tool is the standard method for firmware recovery on MTK devices. Here is what flashing the stock firmware can help with:
- Restore system apps that were accidentally removed or corrupted.
- Resolve OTA update failures and battery drain issues.
- Fix startup loops, lagging, and freezing on your device.
- Restore the original Tecno stock ROM to keep your warranty valid.
- Unlock your device if it has been locked or disabled.
- Fix Wi-Fi, Bluetooth, or mobile data connectivity that stopped working after an update.
- 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 Camon CX 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 “CX”. If it is a different variant, do not use this firmware.
- Cross-Check the Chipset: The Camon CX CX uses MediaTek MT6755 Helio P10. 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 Camon CX
Here is a quick overview of the official firmware specifications:
| Firmware Information | Details |
|---|---|
| Device Model | Tecno Camon CX |
| Firmware Version | V91, V166 |
| File Size | 1.8 GB to 1.95 GB |
| Android Version | Android 7.0 (Nougat) with HiOS |
| Platform | MediaTek MT6755 Helio P10 |
| Release Date | Released 2017, March |
| Region | Global, Africa and Asia |
| File Type | ZIP (Includes Scatter File [MT6xxx_Android_scatter.txt], preloader.bin, boot.img, system.img, recovery.img, lk.bin, logo.bin, nvram.img, and more) |
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 | V166, download this one. It is the latest Tecno Camon CX 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 V91, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V166 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V166 failed with a flash error | Try V91 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V166, 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 Camon CX Firmware
Download the official stock firmware for your Tecno Camon CX below. The latest available version is V166. 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_Camon_CX_MT6755_V91_170303.zip Size: 1.8 GB | Download Link | Download Link2 |
| File Name: CX-H501DEFG-N-180109V166 Size: 1.95 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 Camon CX (CX) should not be confused with other Camon CX variants that may have different chipsets or regional firmware. Even devices in the same Camon CX line can use completely different processors. Always verify your exact model code “CX” in Settings > About Phone before downloading any firmware from this page.
- Go to Settings and verify your model is exactly CX. Phones with similar names can have completely different hardware.
- The chipset in your device should be MediaTek MT6755 Helio P10. If it is different, this firmware will not work.
- Always download directly from the table on this page to ensure you have the correct build.
- Check the file size after downloading, a mismatch with the listed size means a partial or corrupt download.
Prepare Your Tecno Camon CX for Flashing
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 Camon CX 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.
- IMEI Backup: Open the dialer and enter *#06#. Write both IMEI numbers down on paper or take a screenshot. If you ever need to repair your IMEI after flashing, these are essential.
- Remove All Google Accounts: Go to Settings, Accounts, and sign out of every Google account on the device. Leaving accounts signed in triggers FRP lock after a flash, which blocks you from setting up the phone.
- Backup Everything: Photos, contacts, messages, WhatsApp data, move it all to a computer or cloud service. The flash will restore the phone to factory state with nothing on it.
- 50% Battery Minimum: Do not start with a low battery. If power cuts out during the flash, the device can become unresponsive and much harder to fix.
- USB Cable and Computer: Use a proper data-transfer USB cable and a Windows PC. Avoid USB hubs, connect directly to the motherboard port for a stable connection.
- Download and Install Drivers:
Tecno Camon CX Firmware Installation Guide
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.
- Download and Extract:
- Download the correct firmware package from the links above.
- Extract the ZIP to a simple folder path, avoid paths with spaces or special characters, as some flash tools have trouble with them.
- Install the Listed Drivers:
- Confirm all drivers listed above are installed and that your PC has been restarted since installation. Skipping the restart is a common reason drivers do not work correctly.
- 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 the “Download” button to begin.
- Do not disconnect, move the cable, or touch the device until the process is fully complete. Disconnecting mid-flash is how devices get bricked.
- Wait and Reboot:
- Once flashing finishes successfully, disconnect the device.
- Power on your device. The first boot will take longer than usual, give it up to 8 minutes.
Normal Behavior After Installing Tecno Camon CX Firmware
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.
- 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.
- 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.
- 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.
- 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.
- 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.
What to Do if Tecno Camon CX Flash Fails
- Tecno Camon CX Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the CX, 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 Camon CX 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.

Tecno Camon CX Flashing FAQ
Q1: 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.
Q2: 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.
Q3: 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.
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: Can I flash this firmware if my phone does not turn on at all?
A: Yes, in most cases. As long as the phone responds to a USB connection (even with a black screen), the flash tool can detect it. If the battery is completely drained, charge it for at least 15 minutes first.
Q6: Will flashing void my warranty?
A: Flashing official stock firmware generally does not void your warranty since you are restoring the device to its factory-intended state. However, some manufacturers may flag that the bootloader was unlocked or that the flash counter increased. Check your specific warranty terms with Tecno support if you are concerned.
Q7: Is this firmware compatible with other Tecno models?
A: No. This firmware is built specifically for the Tecno Camon CX running on the MediaTek MT6755 Helio P10 chipset. Even variants of the Camon CX 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.
Q8: 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.
