Tecno Pop 4 BC1s Firmware (Flash File) Drivers, Tools & Guide
Tecno Pop 4 BC1s devices often arrive with FRP locks, bootloop problems, or a stuck logo. This guide provides the necessary files, tools, and instructions to resolve these issues.
One important step before starting is extracting the firmware to a simple folder path, such as C:FirmwareBC1s. SP Flash Tool can struggle to locate the scatter file if the path contains spaces or special characters. This simple step prevents frustrating delays later on.
The Tecno Pop 4 BC1s launched in 2020 and runs on a MediaTek MT6739 chipset. This means you must use SP Flash Tool and VCOM drivers for flashing. The stock firmware includes Android 10 (Go edition) and HIOS, which defines the default apps and interface after the update. Windows 10 or 11 may require manual driver installation rather than plug-and-play compatibility.
There are 11 firmware versions available for the Tecno Pop 4 BC1s. This page covers multiple Android builds and security patch levels. The device was released in 2020, and this page is updated with the latest firmware builds as they become available.
Your Tecno Pop 4 BC1s firmware comes as a compressed ZIP file. Download and extract it using WinRAR or 7-Zip. Open the folder and confirm it contains the scatter file before proceeding.
Flashing the stock firmware restores the device to its original factory condition. This clean state removes all data stored on the phone, including photos, messages, and apps. This process fixes stuck logos, FRP locks, and software corruption.
Tecno Pop 4 BC1s FRP Bypass
To bypass FRP on the Tecno Pop 4 BC1s, use a free Android apps launcher that allows access to the setup wizard settings.
How to Wipe Tecno Pop 4 BC1s to Factory Settings
To perform a factory reset without a computer, power off the device, then hold Volume Up and Power simultaneously until the recovery menu appears.
A hard reset erases all data and restores the Tecno Pop 4 BC1s to its original factory state. This fixes software problems such as 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 required.
Verify Your Tecno Pop 4 BC1s Model Before Downloading
The most common error when flashing firmware is using a file meant for a different variant.
- Open About Phone: Your device model must read “BC1s” exactly. Even small differences in the code can mean a completely different chipset and partition layout.
- Verify the Chipset Type: This firmware targets MediaTek MT6739 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.
Why Flash Stock ROM on Tecno Pop 4 BC1s?
Stock firmware recovery is necessary on MediaTek devices like the Tecno Pop 4 BC1s because SP Flash Tool is the standard method for repairing software issues.
- Unlock your device if it has been locked or disabled.
- Remove persistent malware or adware that survives a factory reset.
- Recover your device when it only boots into recovery mode.
- Restore the original Tecno stock ROM to keep your warranty valid.
- Clear a forgotten screen lock, PIN, or pattern without needing the original credentials.
- 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.

Which Firmware Version Should I Download?
Selecting the correct firmware version depends on the specific issue your device is experiencing.
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V021, download this one. It is the latest Tecno Pop 4 BC1s 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 V019, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V021 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V021 failed with a flash error | Try V019 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V021, 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 Pop 4 BC1s (BC1s) should not be confused with other Pop 4 variants that may have different chipsets or regional firmware. Even devices in the same Pop 4 line can use completely different processors. Always verify your exact model code “BC1s” in Settings > About Phone before downloading any firmware from this page.
- Confirm your exact model is BC1s, check About Phone, not the marketing name on the box.
- Your device must have a MediaTek MT6739 chipset. Boot into recovery mode to verify if unsure.
- Only use files downloaded from this page. Third-party mirrors may serve modified or incomplete packages.
- Compare the file size against the download table. If it does not match, the download is likely corrupt or incomplete.
Prerequisites for Tecno Pop 4 BC1s Firmware
Proper driver installation is critical for SP Flash Tool to detect the Tecno Pop 4 BC1s correctly.
- 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:
Step-by-Step: Flash Tecno Pop 4 BC1s Stock ROM
Flashing the stock ROM requires SP Flash Tool and the correct scatter file for the Tecno Pop 4 BC1s.
- Prepare the Flash Files:
- Go to the download section and grab the firmware package that matches your device.
- Unzip the file to a folder on your desktop. Avoid using folder names with non-English characters or spaces, the flash tool may not read them correctly.
- Confirm Driver Setup:
- The drivers listed in prerequisites need to be installed and working before you connect the phone. If you are not sure, reinstall them and restart your computer.
- 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 “Download” to kick off the firmware write.
- Hands off the phone and cable until the tool shows completion. Moving or disconnecting the device mid-flash is the most common cause of a bricked phone.
- Wait and Reboot:
- When you see the success message, disconnect the USB cable.
- Hold the power button to boot the phone. Give it a solid 5 to 8 minutes for the first startup, this is normal.
Tecno Pop 4 BC1s Flashing Problems and Fixes
- Tecno Pop 4 BC1s Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the BC1s, 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.
After Flashing: What Happens Next on Tecno Pop 4 BC1s
A successful flash will restore the device to factory settings and remove all personal data.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Missing IMEI or Corrupt Baseband on Tecno Pop 4 BC1s 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.

Common Questions About Flashing Tecno Pop 4 BC1s
The following section answers common questions regarding the Tecno Pop 4 BC1s flashing process.
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: 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: 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: 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.
Q5: Will flashing erase my data?
A: Yes, flashing with SP Flash Tool restores the device to factory state, including Android 10 (Go edition), HIOS 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.
Q6: 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.
Q7: 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.
Q8: 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.
