Tecno Camon 20s Pro 5G CK8nB Firmware (Flash File) Drivers, Tools & Guide

I have handled many Tecno devices over the years, and the Tecno Camon 20s Pro 5G CK8nB comes in frequently, usually with FRP locks, bootloop issues, or the phone 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:FirmwareCK8nB. 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 3 firmware files available for the Tecno Camon 20s Pro 5G CK8nB on this page. Pick the one that matches your current Android version for the smoothest flash. The stock firmware ships with Android 13, HIOS 13, which determines the default apps, security features, and interface you will see after flashing. The Tecno Camon 20s Pro 5G CK8nB firmware runs on a MediaTek Dimensity 8020 (MT6893) chipset, which means you will use SP Flash Tool and VCOM/MTK drivers for flashing. These are included in the prerequisites below.

With 3 firmware versions archived for the Tecno Camon 20s Pro 5G CK8nB, 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 20s Pro 5G lineup.

Your Tecno Camon 20s Pro 5G CK8nB 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.

Be aware that flashing overwrites the entire software partition. Your data, apps, and accounts will all be removed. This full wipe is how the flash resolves deep software issues, anything from FRP locks and boot failures to Wi-Fi problems and app crashes.

Tecno Camon 20s Pro 5G CK8nB Hard Reset Guide

To perform a hard reset on the Tecno Camon 20s Pro 5G CK8nB 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 20s Pro 5G CK8nB 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 20s Pro 5G CK8nB FRP Bypass

The fastest method to bypass FRP on Tecno Camon 20s Pro 5G CK8nB 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.

Common Reasons to Reinstall Tecno Camon 20s Pro 5G CK8nB Firmware

The Tecno Camon 20s Pro 5G CK8nB 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:

• Recover your device when it only boots into recovery mode.

Choosing the Right Firmware Version

The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:

1. Identify Your Device Model: Go to About Phone and confirm your model is Tecno Camon 20s Pro 5G CK8nB. Check the full model string, not just the name.
2. Verify the Build Number: Look for the identifier “CK8nB” in your device build details.
3. Confirm the Chipset: According to Tecno specifications, the Camon 20s Pro 5G CK8nB runs on MediaTek Dimensity 8020 (MT6893).
4. Match the Firmware Version: Check the version and regional details against what is listed in the download table above.
5. Verify in Recovery Mode: If you are not sure about the chipset or build number, boot into recovery mode, it displays this information clearly and is the most reliable way to confirm before you flash.

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	V378, download this one. It is the latest Tecno Camon 20s Pro 5G CK8nB 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 V299, sometimes the latest OTA introduces new bugs and an older build runs better.
IMEI missing after a previous flash	Re-flash V378 first, then follow the IMEI repair guide. Do not skip the reflash.
V378 failed with a flash error	Try V299 instead and double-check your scatter file selection before assuming the firmware is the problem.
Restoring to factory / warranty repair	V378, 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 Camon 20s Pro 5G CK8nB 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 Camon 20s Pro 5G CK8nB 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. Record IMEI Before Flashing: Dial *#06# and save both IMEI numbers somewhere safe, a screenshot works. If flashing corrupts the baseband, these numbers are what you will need to restore cellular connectivity.
2. Unlink Google Accounts: Go to Settings, then Accounts, and remove all Google accounts. This prevents Factory Reset Protection from activating after the flash. It is the single most skipped step and causes the most post-flash headaches.
3. Full Data Backup: Flashing erases everything. Transfer your photos, contacts, app data, and any important files to your computer or cloud backup before starting.
4. Charge the Battery: Make sure you have at least 50% charge. A dead battery during a flash can corrupt the system partition and turn a fixable problem into a much bigger one.
5. Windows PC and USB Cable: You will need a Windows computer and a data-capable USB cable. Cheap charge-only cables are the number one reason flash tools fail to detect devices.
6. Driver Installation:
   • VCOM Drivers
   • Tecno USB Drivers

Tecno Camon 20s Pro 5G CK8nB 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.

1. 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:flash to avoid issues with some tools.
2. Check Drivers:
   • All drivers from the prerequisites must be installed before connecting your device. Restart your computer after installing them.
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:
   • 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.
6. 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 Is Normal After a Tecno Camon 20s Pro 5G CK8nB 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.
• 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.
• 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.
• 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.
• 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.
• 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.

Tecno Camon 20s Pro 5G CK8nB Flashing Problems and Fixes

1. Tecno Camon 20s Pro 5G CK8nB Not Recognized by SP Flash Tool:
   • In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the CK8nB, 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.

Missing IMEI or Corrupt Baseband on Tecno Camon 20s Pro 5G CK8nB 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.

Tecno Camon 20s Pro 5G CK8nB Flashing FAQ

Q1: 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.

Q2: 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.

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: 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.

Q5: Is this firmware compatible with other Tecno models?
A: No. This firmware is built specifically for the Tecno Camon 20s Pro 5G CK8nB running on the MediaTek Dimensity 8020 (MT6893) chipset. Even variants of the Camon 20s Pro 5G 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.

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: 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.

Q8: 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.

Will flashing firmware on Tecno Camon 20s Pro 5G CK8nB erase my data?
Yes. Flashing stock firmware on the Tecno Camon 20s Pro 5G CK8nB with SP Flash Tool performs a full factory reset. All apps, photos, contacts, and accounts will be removed. Back up everything important before you start. There is no way to recover data after flashing.

How do I check my Tecno Camon 20s Pro 5G CK8nB model number before flashing?
Go to Settings > About Phone on your Tecno Camon 20s Pro 5G CK8nB and look for the model number “CK8nB”. You can also confirm by entering recovery mode (Volume Up + Power while powered off) which displays the build number and model code. Always match this exactly with the firmware filename before flashing.

What chipset does the Tecno Camon 20s Pro 5G CK8nB use?
The Tecno Camon 20s Pro 5G CK8nB uses the MediaTek Dimensity 8020 (MT6893) chipset, a MediaTek processor. This means you need SP Flash Tool and VCOM/MTK USB drivers to flash firmware. MediaTek devices use scatter-file-based flashing, which is different from Qualcomm (QFIL) or Samsung (Odin) methods.

Can flashing firmware fix a bricked Tecno Camon 20s Pro 5G CK8nB?
Yes. If your Tecno Camon 20s Pro 5G CK8nB is stuck on the logo, in a bootloop, or will not turn on, flashing the stock firmware with SP Flash Tool can restore it to working condition. This is the standard repair method used by service centers for Tecno devices.
