Tecno Pop 4 BC1s Firmware (Flash File) Drivers, Tools & Guide
The Tecno Pop 4 BC1s frequently requires firmware recovery for issues like FRP locks, bootloops, or stuck on the Tecno logo. This guide consolidates all necessary resources: firmware files, tools, and proven procedures.
Before starting, extract firmware to a simple folder path such as C:FirmwareBC1s. SP Flash Tool may fail to locate the scatter file if the path contains spaces or special characters, causing unnecessary delays.
The Tecno Pop 4 BC1s released in 2020 uses a MediaTek MT6739 chipset, requiring SP Flash Tool with VCOM/MTK drivers for flashing. Stock firmware includes Android 10 (Go edition) with HIOS, defining default apps, security features, and interface.
Eleven firmware versions are archived for this model, covering multiple Android builds and security patch levels. This page maintains the latest available firmware builds as they become available.
Download the Tecno Pop 4 BC1s firmware as a compressed ZIP file. Extract using WinRAR or 7-Zip. Confirm the scatter file exists in the extracted folder before proceeding.
Flashing restores the device to factory condition, removing all data including photos, messages, and apps. This clean state resolves stuck logos, FRP locks, software corruption, and performance issues.
Tecno Pop 4 BC1s FRP Bypass
The quickest FRP bypass for Tecno Pop 4 BC1s uses a free Android apps launcher that grants access to settings during setup. After flashing or factory reset, a Google account lock (FRP) may appear. Our free Android apps launcher bypasses this efficiently. Remove your Google account before flashing to prevent this issue.
How to Wipe Tecno Pop 4 BC1s to Factory Settings
To factory reset Tecno Pop 4 BC1s without a computer, power off the device completely. Hold Volume Up and Power simultaneously until recovery mode appears. Use volume keys to navigate to “Wipe Data/Factory Reset” and confirm with the Power button.
A hard reset erases all data and restores Tecno Pop 4 BC1s to its original state, fixing software problems like slow performance, app crashes, forgotten screen locks, and bootloops. If issues persist after reset, flash stock firmware using SP Flash Tool.
Verify Your Tecno Pop 4 BC1s Model Before Downloading
Flashing incompatible firmware is the most common error. Verify your exact device identity before downloading:
- Check About Phone: Your device model must show “BC1s” exactly. Minor code differences indicate different chipsets and partition layouts.
- Confirm Chipset Type: This firmware targets MediaTek MT6739 specifically. Flashing other chipsets fails or bricks the device.
- Compare Firmware Version: Match your build number with available downloads to select the correct file.
- Use Recovery Mode: Settings are inaccessible, boot into recovery mode to view build and chipset details.
- Check Regional Compatibility: Some firmware targets specific regions. Confirm the download matches your device origin.

Which Firmware Version Should I Download?
Select the correct firmware based on your situation:
| 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 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
Do not skip this section. Most failed Tecno flashes result from rushing through preparation steps. The VCOM driver installation is essential for the Tecno Pop 4 BC1s and other MediaTek devices. Windows may show the device in Device Manager, but SP Flash Tool will not detect it without the correct VCOM driver.
- IMEI Backup: Open the dialer and enter *#06#. Write both IMEI numbers down on paper or take a screenshot. If you need to repair IMEI after flashing, these are essential.
- Remove All Google Accounts: Go to Settings, Accounts, and sign out of every Google account. Leaving accounts signed in triggers FRP lock after a flash, blocking setup.
- Backup Everything: Photos, contacts, messages, WhatsApp data, move all to a computer or cloud. The flash will restore the phone to factory state.
- 50% Battery Minimum: Do not start with low battery. Power cuts during flashing can render the device unresponsive.
- USB Cable and Computer: Use a data-transfer USB cable and Windows PC. Avoid USB hubs, connect directly to the motherboard port.
- Download and Install Drivers:
Step-by-Step: Flash Tecno Pop 4 BC1s Stock ROM
We use SP Flash Tool for this process. For older devices, try SP Flash Tool v5.1924 first. Newer SP Flash Tool versions require a DA (Download Agent) file that older firmware packages lack, causing “Auth” errors. If SP Flash Tool requests 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. The complete SP Flash Tool guide is also available.
- Prepare the Flash Files:
- Download the firmware package matching your device.
- Unzip to a folder on your desktop. Avoid non-English characters or spaces in folder names.
- Confirm Driver Setup:
- The drivers listed in prerequisites must be installed and working before connecting the phone. Reinstall and restart if unsure.
- Load the Firmware File:
- Click “Scatter-loading” and select the “scatter.txt” file from the extracted firmware folder.
- Connect Your Device:
- Power off the phone completely, not sleep mode.
- Connect to your PC via USB cable. The flash tool will detect it automatically.
- Start Flashing:
- Click “Download” to begin the firmware write.
- Keep hands off the phone and cable until completion. Disconnecting mid-flash is the most common cause of a bricked phone.
- Wait and Reboot:
- When the success message appears, disconnect the USB cable.
- Hold the power button to boot the phone. Allow 5-8 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:
- This is usually a driver issue, not a cable problem. Reinstall VCOM drivers for the BC1s, restart your PC, and try again.
- If unresolved, switch to a USB 2.0 port, USB 3.0 ports often cause detection issues with MediaTek devices.
- Still not working? Temporarily disable your antivirus, which can block VCOM driver loading silently.
- Boot Loop After Flashing:
- Enter recovery mode and perform a factory reset. Most post-flash bootloops on MediaTek stem from cached data conflicts, a wipe from recovery usually fixes this without reflashing.
- Wrong Scatter File / Firmware Mismatch:
- If SP Flash Tool throws an error at download start, check your scatter file first. Mismatch between scatter file and device build is a common flash error cause.
- “Download DA FAIL” Error:
- This error frequently occurs. It almost always indicates improper VCOM driver installation. Reinstall the driver, restart your PC, and try again. If unresolved, try SP Flash Tool v5.1924, older devices respond better to this 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 holding Volume Down while plugging in the USB cable to enter BROM mode.
- Auth File / Secure Boot Error in Newer SP Flash Tool:
- Newer SP Flash Tool versions require a DA (Download Agent) authentication file for devices with Secure Boot enabled. If you lack this file, use MTK Client instead, it handles Secure Boot automatically and is simpler.
After Flashing: What Happens Next on Tecno Pop 4 BC1s
Here is what to expect after a successful flash:
- How to know the flash was successful: SP Flash Tool displays a green circle or checkmark upon completion. This confirms a successful flash.
- The phone may ask for language and region again, this is normal after a flash. The setup wizard runs as if the phone were brand new.
- Wi-Fi, Bluetooth, and mobile data should function immediately after setup. If mobile data fails, go to Settings, SIM and Network, and re-enter your APN manually, flashing sometimes clears carrier APN settings.
- Battery percentage may seem inaccurate for the first day. Battery statistics calibrate during normal use. Charge fully once without interruption to stabilize readings.
- Storage will show almost full capacity since all apps and files are gone. The system partition typically ranges from 4 to 8 GB on most devices.
- Dial *#06# immediately after setup to check your IMEI. Do this before inserting a SIM card. If it shows “unknown” or “null”, follow the IMEI repair guide before proceeding.
- Notification sounds and ringtones revert to factory defaults. Any custom tones must be re-downloaded and reassigned in Settings.
Missing IMEI or Corrupt Baseband on Tecno Pop 4 BC1s After Flashing?
A missing or unknown IMEI commonly occurs after MediaTek flashes. The NVRAM partition storing IMEI and calibration data sometimes does not survive intact. This is fixable:
- Check drivers first: Install the Mediatek CDC Driver if not already, IMEI repair tools require it to detect your device. This step is frequently missed.
- Use SN Write Tool or Maui Meta: SN Write Tool is the first option, straightforward for most MTK devices. Maui Meta is the alternative if SN Write fails. 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, the numbers you recorded before flashing.
- Click “Start” and allow completion without interruption.
- Verify after reboot: Once done, reboot your phone and dial *#06#. IMEI numbers should return. If still showing null, repeat the process, the first attempt may not complete correctly.

Common Questions About Flashing Tecno Pop 4 BC1s
Q1: Will flashing void my warranty?
A: Flashing official stock firmware typically does not void your warranty since you restore the device to its factory state. However, some manufacturers may flag bootloader unlocking or increased flash counters. Check Tecno support for specific warranty terms if concerned.
Q2: How do I enter recovery mode?
A: Power off the device completely, then hold Volume Up + Power simultaneously until the recovery menu appears. The recovery menu displays the build number, useful for verifying firmware before flashing.
Q3: What if the flash fails halfway through?
A: Do not panic or disconnect the phone. Close SP Flash Tool, restart it, and retry the flash from the beginning. Most failed flashes simply require repetition. The device usually remains detectable by the flash tool after a failed attempt.
Q4: Can I go back to an older firmware version?
A: Technically possible on some MediaTek builds, but downgrading risks security issues and app compatibility problems. If the latest version causes trouble, leave a comment below, better solutions than rollback usually exist.
Q5: Will flashing erase my data?
A: Yes, flashing with SP Flash Tool restores the device to factory state, including Android 10 (Go edition) with HIOS defaults. All apps, photos, contacts, and accounts are removed. Back up everything needed before starting. Data cannot be recovered once flashing completes.
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 USB connection (even with a black screen), the flash tool detects it. If the battery is completely drained, charge for at least 15 minutes first.
Q7: How long does the flashing process take?
A: The actual flash usually takes 3-10 minutes depending on firmware size and USB speed. The first boot after flashing takes another 3-8 minutes. Do not interrupt the device during either stage. If SP Flash Tool appears stuck, wait several minutes before assuming failure.
Q8: What should I do if I encounter an FRP lock after flashing?
A: Use our free Android apps launcher. FRP activates when a Google account was still signed in before flashing. This is why signing out of Google accounts before flashing prevents this issue.
