Tecno Camon 18 Premier CH9n Firmware (Flash File) Drivers, Tools & Guide
I handle Tecno repairs frequently. The Camon 18 Premier CH9n is a common visitor in my workshop, often arriving with FRP locks, bootloop issues, or a stuck 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:FirmwareCH9n. 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 Camon 18 Premier CH9n runs on a MediaTek MT6781 Helio G96 chipset. This means you will use SP Flash Tool and VCOM/MTK drivers for flashing. These are included in the prerequisites below. The stock firmware ships with Android 11, HIOS 8.0, which determines the default apps, security features, and interface you will see after flashing.
The Tecno Camon 18 Premier CH9n was released in 2021. This page is maintained with the latest available firmware builds as they become available. The firmware was sourced directly from verified repositories and checked for integrity before being listed on this page.
Your Tecno Camon 18 Premier CH9n 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.
Remove FRP Lock on Tecno Camon 18 Premier CH9n
The fastest way to bypass FRP on Tecno Camon 18 Premier CH9n 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.
How to Wipe Tecno Camon 18 Premier CH9n to Factory Settings
To factory reset Tecno Camon 18 Premier CH9n 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 18 Premier CH9n 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.
Tecno Camon 18 Premier CH9n Firmware Compatibility Check
The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:
- Check About Phone: Open Settings and find your exact model number. It should read “CH9n”, not a similar name, the exact code.
- Match the Chipset: This firmware is built for MediaTek MT6781 Helio G96. If your device has a different processor, it will not flash correctly.
- Look at the Build Number: The build string in your current software should reference the Camon 18 Premier line. Cross-check it with the firmware table below.
- Check Recovery Mode: Power off, hold Volume Up + Power until recovery appears. The screen displays your chipset and current build, use this to confirm.
- Compare File Details: Make sure the version listed in the download table matches what you expect for your device and region.
When Should You Flash Tecno Camon 18 Premier CH9n?
The Tecno Camon 18 Premier CH9n 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 system apps that were accidentally removed or corrupted.
- Remove persistent malware or adware that survives a factory reset.
- Resolve OTA update failures and battery drain issues.
- Clear a forgotten screen lock, PIN, or pattern without needing the original credentials.
- Recover your device when it only boots into recovery mode.
- Restore the original Tecno stock ROM to keep your warranty valid.
- Recover from “Download DA FAIL” errors and Secure Boot authentication issues specific to the MediaTek chipset in your device.

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 | V758, download this one. It is the latest Tecno Camon 18 Premier CH9n 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 V720, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V758 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V758 failed with a flash error | Try V720 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V758, 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 18 Premier CH9n Firmware
Download the official stock firmware for your Tecno Camon 18 Premier CH9n below. The latest available version is V758. 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.

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 18 Premier CH9n (CH9n) should not be confused with other Camon 18 Premier variants that may have different chipsets or regional firmware. Even devices in the same Camon 18 Premier line can use completely different processors. Always verify your exact model code “CH9n” in Settings > About Phone before downloading any firmware from this page.
- Open About Phone and make sure the model code reads CH9n. Do not rely on the name printed on the phone case.
- Verify the chipset is MediaTek MT6781 Helio G96. You can see this in recovery mode or by checking the device specifications online.
- Use only the download links provided on this page.
- After downloading, right-click the file and check Properties to confirm the size matches the table above. If it does not, download it again.
What You Need Before Flashing Tecno Camon 18 Premier CH9n
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 18 Premier CH9n 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.
- Write Down Your IMEI: Open your phone dialer and type *#06#. Take a photo of the screen showing both IMEI numbers. You may need these later to fix your IMEI if it gets wiped during the flash.
- Sign Out of Google: Open Settings, go to Accounts, and remove every Google account from the device. If you skip this, Google will lock the phone after flashing and you will need to do an FRP bypass.
- Save Your Files: Copy everything important to a PC or cloud storage. After flashing, the phone will be completely empty, no apps, no photos, no messages.
- Battery Check: Charge to at least 50%. If the phone dies during flashing, you could end up with a device that will not turn on at all.
- Get the Right Cable: You need a USB data cable, the kind that can transfer files, not just charge. Plug it into a USB 2.0 port on a Windows PC for the most reliable connection.
- Set Up Drivers:
Install Stock Firmware on Tecno Camon 18 Premier CH9n
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 Unpack:
- Pick the correct firmware version from the downloads above and save it to your PC.
- Extract the ZIP file. If the extracted folder contains another ZIP inside, extract that one too. You should end up with the actual firmware files, not another archive.
- Driver Check:
- Double-check that you have installed the required drivers. A missing driver is the most common reason the flash tool cannot detect your phone. Reboot your PC after installing.
- 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:
- Start the flash by clicking “Download”.
- Leave everything untouched until completion. Even bumping the USB cable can interrupt the write and cause a failed flash.
- Wait and Reboot:
- The flash is complete when the tool shows a success indicator. Disconnect your phone.
- Turn the phone on. Do not worry if it sits on the boot logo for several minutes, the system is rebuilding itself from scratch.
What to Do if Tecno Camon 18 Premier CH9n Flash Fails
- Tecno Camon 18 Premier CH9n Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the CH9n, 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.
Normal Behavior After Installing Tecno Camon 18 Premier CH9n 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.
- 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.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- 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.
- 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.
- 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.
- 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.
Missing IMEI or Corrupt Baseband on Tecno Camon 18 Premier CH9n 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 18 Premier CH9n Flashing FAQ
Q1: 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.
Q2: Can I go back to an older firmware version?
A: It is technically possible on some MediaTek builds, but downgrading can cause security issues and app compatibility problems. If the latest version is causing trouble, leave a comment below, there is usually a better fix than rolling back.
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: 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.
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: 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: 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.
