Tecno Camon 20 Premier CK9n Firmware (Flash File) Drivers, Tools & Guide
I have worked with Tecno phones for a while, and the Tecno Camon 20 Premier CK9n comes in often. Most of the time, it is stuck on the logo or dealing with FRP locks. 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:FirmwareCK9n. 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.
Released in 2023, the Tecno Camon 20 Premier CK9n has been on the market long enough that multiple firmware builds are available, giving you options if one version causes issues. The Tecno Camon 20 Premier CK9n firmware runs on a MediaTek Dimensity 8050 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 Camon 20 Premier CK9n on this page. Pick the one that matches your current Android version for the smoothest flash.
With 3 firmware versions archived for the Tecno Camon 20 Premier CK9n, this page covers multiple Android builds and security patch levels. As a Transsion Holdings brand, Tecno devices share similar chipset architectures and flashing procedures across the Camon 20 Premier lineup.
Your Tecno Camon 20 Premier CK9n 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.
Flashing replaces your current software completely and wipes all personal data. This is by design, it is what clears out FRP locks, bootloops, pattern locks, app crashes, and other software-level problems that a regular reset cannot fix.
Bypass Google Lock on Tecno Camon 20 Premier CK9n
The fastest way to bypass FRP on Tecno Camon 20 Premier CK9n 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 20 Premier CK9n to Factory Settings
To factory reset Tecno Camon 20 Premier CK9n 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 20 Premier CK9n 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.
How to Pick the Correct Tecno Camon 20 Premier CK9n 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:
- Open About Phone: Your device model must read “CK9n” exactly. Even small differences in the code can mean a completely different chipset and partition layout.
- Verify the Chipset Type: This firmware targets MediaTek Dimensity 8050 specifically. Flashing it on a different chipset will fail or could brick the device.
- Check Your Current Firmware Version: Compare your build number with the versions listed in the download section to decide which file to use.
- 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.
- Regional Compatibility: Some Tecno firmware packages target specific regions. Confirm the download matches your device origin.
When Should You Flash Tecno Camon 20 Premier CK9n?
The Tecno Camon 20 Premier CK9n firmware helps with bootloops, random restarts, and security patches. Here is what flashing the stock firmware can do for you:
- Recover your device when it only boots into recovery mode.
- Repair a phone that shuts down randomly or restarts in a loop.
- Remove persistent malware or adware that survives a factory reset.
- Update to the latest Android version supported by your phone.
- Clear a forgotten screen lock, PIN, or pattern without needing the original credentials.
- Restore system apps that were accidentally removed or corrupted.
- 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 | V3718, download this one. It is the latest Tecno Camon 20 Premier CK9n 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 V2099, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V3718 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V3718 failed with a flash error | Try V2099 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V3718, 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 20 Premier CK9n Firmware
Download the official stock firmware for your Tecno Camon 20 Premier CK9n below. The latest available version is V3718. 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 20 Premier CK9n (CK9n) should not be confused with other Camon 20 Premier variants that may have different chipsets or regional firmware. Even devices in the same Camon 20 Premier line can use completely different processors. Always verify your exact model code “CK9n” in Settings > About Phone before downloading any firmware from this page.
- Go to Settings and verify your model is exactly CK9n. Phones with similar names can have completely different hardware.
- The chipset in your device should be MediaTek Dimensity 8050. 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.
What You Need Before Flashing Tecno Camon 20 Premier CK9n
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 20 Premier CK9n 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.
- 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.
- Remove Google Accounts: Sign out of all Google accounts to prevent FRP lock after flashing.
- Back Up Your Data: Back up everything, photos, contacts, WhatsApp chats, important files. Flashing wipes the device completely.
- Charge Your Device: At least 50% battery. A device that powers off during a flash is very difficult to recover.
- USB Cable & PC: Use a proper data USB cable, not a charge-only cable, and a Windows computer with available USB ports.
- Install Required Drivers:
Tecno Camon 20 Premier CK9n 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 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.
Fix Common Tecno Camon 20 Premier CK9n Firmware Errors
- Tecno Camon 20 Premier CK9n Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the CK9n, 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.
What Is Normal After a Tecno Camon 20 Premier CK9n 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.
- The phone may ask for language and region again, this is normal after a flash. You are starting from a clean state, so the setup wizard runs just like when the phone was brand new.
- 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.
- 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.
- 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.
- 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.
- 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 20 Premier CK9n 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 20 Premier CK9n Flashing FAQ
Q1: 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.
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: 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.
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 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.
Q6: 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.
Q7: 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.
Q8: Is this firmware compatible with other Tecno models?
A: No. This firmware is built specifically for the Tecno Camon 20 Premier CK9n running on the MediaTek Dimensity 8050 chipset. Even variants of the Camon 20 Premier 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.
