Tecno Camon 20 Pro 5G CK8n Firmware (Flash File) Drivers, Tools & Guide
This guide provides the stock firmware, drivers, and tools needed to restore your Tecno Camon 20 Pro 5G CK8n to working condition. You will find the stock firmware, required drivers, and detailed instructions here. Troubleshooting and IMEI repair methods are also included.
I have handled Tecno devices for a long time, and the Tecno Camon 20 Pro 5G CK8n comes in regularly, usually with FRP locks, bootloop issues, or stuck on the Tecno logo. This guide consolidates everything you need: the firmware, the tools, and the exact process I use myself.
I suggest saving the firmware to a simple folder path, like C:FirmwareCK8n. SP Flash Tool can sometimes struggle to locate the scatter file if the folder path contains spaces or special characters. It is a minor detail, but it saves a frustrating few minutes of wondering why the tool is not loading the file.
The stock firmware ships with Android 13 and HIOS 13, which sets the default apps, security features, and interface you will see after flashing. Released in 2023, the Tecno Camon 20 Pro 5G CK8n has been on the market long enough that multiple firmware builds are available. This page lists 5 firmware builds for the Tecno Camon 20 Pro 5G CK8n, covering multiple Android versions and security patch levels. If one build does not work, try a different version.
This page covers multiple Android builds and security patch levels for the Tecno Camon 20 Pro 5G CK8n. As a Transsion Holdings brand, Tecno devices share similar chipset architectures and flashing procedures across the Camon 20 Pro 5G lineup.
Your Tecno Camon 20 Pro 5G CK8n 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 will erase 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.
Tecno Camon 20 Pro 5G CK8n Hard Reset Guide
To factory reset Tecno Camon 20 Pro 5G CK8n 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 Pro 5G CK8n 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.
Bypass Google Lock on Tecno Camon 20 Pro 5G CK8n
The fastest way to bypass FRP on Tecno Camon 20 Pro 5G CK8n 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.
Why Do We Need Tecno Camon 20 Pro 5G CK8n Firmware?
We need stock firmware for the Tecno Camon 20 Pro 5G CK8n to resolve issues caused by corrupted system files. Here is what flashing the stock firmware can help with:

Tecno Camon 20 Pro 5G CK8n Firmware Compatibility Check
The single biggest mistake is flashing firmware meant for a different variant, so you must verify your exact device identity before downloading:
- Find Your Model Code: Go to Settings, then About Phone. The code should be “CK8n”. If it is a different variant, do not use this firmware.
- Cross-Check the Chipset: The Camon 20 Pro 5G CK8n uses MediaTek Dimensity 8050 (MT6893). 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.

Which Firmware Version Should I Download?
This guide helps you choose the right file based on your specific situation, such as whether the phone is dead, slow, or locked.
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V765, download this one. It is the latest Tecno Camon 20 Pro 5G CK8n 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 V519, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V765 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V765 failed with a flash error | Try V519 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V765, 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.

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 Pro 5G CK8n (CK8n) should not be confused with other Camon 20 Pro 5G variants that may have different chipsets or regional firmware. Even devices in the same Camon 20 Pro 5G line can use completely different processors. Always verify your exact model code “CK8n” in Settings > About Phone before downloading any firmware from this page.
- The model code on your phone must match CK8n exactly. Even a single letter variant (like adding or dropping an “i” or “s”) can mean a different chipset inside.
- Your chipset should be MediaTek Dimensity 8050 (MT6893). Recovery mode shows this information if you are not sure.
- Do not mix firmware from other download sites with the files on this page.
- If the downloaded file is much smaller than what is listed in the table above, re-download it, partial files will fail.
Prerequisites for Tecno Camon 20 Pro 5G CK8n Firmware
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 Pro 5G CK8n 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 Pro 5G CK8n 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 the Firmware Package:
- Use the download links in the table above to get the correct firmware file for your device.
- Extract the archive with WinRAR or 7-Zip. Use a short folder path like
D:flashto avoid issues with some tools.
- Check Drivers:
- All drivers from the prerequisites must be installed before connecting your device. Restart your computer after installing them.
- 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:
- Press “Download” to begin writing the firmware to your device.
- Do not unplug the phone, close the flash tool, or interact with the device until the process is 100% complete.
- Wait and Reboot:
- After the tool confirms the flash is complete, safely disconnect your phone.
- Press the power button to start your device. The initial boot is slow, wait up to 8 minutes before assuming there is a problem.
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.
- 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.
- 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.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- 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.
- 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.
- 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.
Common Issues When Flashing Tecno Camon 20 Pro 5G CK8n
- Tecno Camon 20 Pro 5G CK8n Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the CK8n, 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 20 Pro 5G CK8n 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 Pro 5G CK8n Firmware FAQ
Q1: 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.
Q2: 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.
Q3: 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.
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: Will flashing erase my data?
A: Yes, flashing with SP Flash Tool restores the device to factory state, including Android 13, HIOS 13 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.
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: 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.
