Tecno Pop 5 LTE BD4 Firmware (Flash File) Drivers, Tools & Guide
Flashing the Tecno Pop 5 LTE BD4 with Unisoc SC9863A is usually straightforward, but many users run into trouble by selecting the wrong firmware file. The most common issue is using an incompatible .pac file, which causes errors in SPD Research Tool. This guide provides the correct firmware, the right tool, and clear steps to avoid mistakes.
Important note: Unisoc firmware comes as a single .pac file inside a ZIP archive, unlike MediaTek devices which use multiple partition files. Before extracting, verify the ZIP contains the .pac file to avoid wasting time with corrupted or incomplete downloads.
The Tecno Pop 5 LTE BD4 is powered by the Unisoc SC9863A chipset, so flashing requires SPD Research Tool and SPD USB drivers. These tools are designed only for Unisoc devices and are not compatible with MediaTek or Qualcomm chipsets. The stock firmware includes Android 11 with HIOS 7.6, which sets up the default apps and interface. Since the phone was released in 2021, USB drivers on Windows 10 or 11 might need manual installation for a proper connection.
All firmware files on this page have been verified against three independent sources to ensure they are authentic and unmodified. We have 23 firmware versions for the Tecno Pop 5 LTE BD4, covering various Android builds and security patches.
The firmware for your Tecno Pop 5 LTE BD4 is in a ZIP file. Download it and extract using WinRAR or 7-Zip. After extraction, check the folder for the .pac file before starting the flash process.
Flashing stock firmware will erase all data from your phone. This is by design and helps fix many software problems such as FRP lock, app crashes, slow performance, forgotten screen locks, devices stuck on the logo, Wi-Fi and Bluetooth issues, battery drain, and soft bricks.
Tecno Pop 5 LTE BD4 FRP Bypass
The fastest way to bypass FRP on Tecno Pop 5 LTE BD4 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.
Factory Reset Tecno Pop 5 LTE BD4 Without a PC
To factory reset Tecno Pop 5 LTE BD4 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 Pop 5 LTE BD4 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 SPD Research Tool is covered in the following sections.
How to Pick the Correct Tecno Pop 5 LTE BD4 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 “BD4” exactly. Even small differences in the code can mean a completely different chipset and partition layout.
- Verify the Chipset Type: This firmware targets Unisoc SC9863A 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 Do We Need Tecno Pop 5 LTE BD4 Firmware?

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 | V18, download this one. It is the latest Tecno Pop 5 LTE BD4 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 V17, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V18 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V18 failed with a flash error | Try V17 instead and double-check your .pac file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V18, clean state, fresh start. |
With Unisoc devices, I recommend using the latest .pac file first. Older versions of the SPD Research Tool firmware can sometimes cause modem issues, which show up as no signal after flashing. Only try an older version if the latest one does not work for you.

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 5 LTE BD4 (BD4) should not be confused with other Pop 5 LTE variants that may have different chipsets or regional firmware. Even devices in the same Pop 5 LTE line can use completely different processors. Always verify your exact model code “BD4” in Settings > About Phone before downloading any firmware from this page.
- Your model number is a variant of BD4 with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.
- Your chipset differs from Unisoc SC9863A. Confirm in recovery mode before proceeding.
- You downloaded the file from a source other than this page.
- The file size differs significantly from the sizes listed in the table above, a size mismatch usually means a partial download, which will fail mid-flash.
Tecno Pop 5 LTE BD4 Flash Setup Checklist
Before anything else, and I mean before you even download the Tecno Pop 5 LTE BD4 firmware, go through this list. The most common reason Tecno Unisoc flashes fail is skipping the driver installation step. SPD Research Tool is very particular about drivers, and Windows will not always tell you when they are missing.
- 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:
- Tecno USB Drivers (includes Spreadtrum USB drivers)
Install Stock Firmware on Tecno Pop 5 LTE BD4
We are using the SPD Research Tool for this. It is the standard tool for Unisoc-based devices. One thing I always do: run it as Administrator. Right-click the .exe and choose “Run as administrator.” This prevents a number of permission-related errors. You can also follow the video guide below if you prefer to see the process in action.
- Download and Extract:
- Download the correct firmware package from the links above.
- Extract the ZIP to a simple folder path, avoid paths with spaces or special characters, as some flash tools have trouble with them.
- Install the Listed Drivers:
- Confirm all drivers listed above are installed and that your PC has been restarted since installation. Skipping the restart is a common reason drivers do not work correctly.
- Load the Firmware File:
- Click the “Load Packet” button and navigate to the extracted folder to select the .pac 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 the “Start” button to begin.
- Do not disconnect, move the cable, or touch the device until the process is fully complete. Disconnecting mid-flash is how devices get bricked.
- Wait and Reboot:
- Once flashing finishes successfully, disconnect the device.
- Power on your device. The first boot will take longer than usual, give it up to 8 minutes.

What to Do if Tecno Pop 5 LTE BD4 Flash Fails
- Tecno Pop 5 LTE BD4 Not Recognized by SPD Research Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the Spreadtrum USB drivers for the BD4, restart your PC, then try again.
- If the device is still not detected, try a different USB port, USB 2.0 ports tend to work more reliably with Unisoc devices than USB 3.0.
- Temporarily disable your antivirus software, it can sometimes block the Spreadtrum driver from loading without showing any error.
- Boot Loop After Flashing:
- Enter recovery mode and perform a factory reset. This resolves most post-flash bootloops on Unisoc devices. If recovery mode is also not accessible, reflash the firmware from scratch.
- Wrong .pac File Selected for BD4:
- If SPD Research Tool throws an error immediately after you load the file, you have likely selected the wrong firmware. Confirm that the .pac file model code matches your Tecno Pop 5 LTE BD4 exactly.
- No Signal After Flashing:
- This usually points to an IMEI issue. Dial *#06#, if it shows null or unknown, follow the IMEI repair guide above before inserting your SIM card.
Normal Behavior After Installing Tecno Pop 5 LTE BD4 Firmware
Here is what is completely normal after a successful flash:
- How to know the flash was successful: SPD Research Tool will show a green “PASSED” message when the flash is complete. If you see this, you are done.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- 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.
- 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.
- 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.
- 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.
Missing IMEI or Corrupt Baseband on Tecno Pop 5 LTE BD4 After Flashing?
A missing IMEI after a Unisoc flash usually means the NVRAM partition was not written correctly during the flash. This happens more often than it should on SPD devices. The WriteIMEI Tool handles this well for Unisoc. Just make sure you have your original IMEI written down from before you flashed, dial *#06# before starting next time. Without the original number, you cannot restore it properly.
Use WriteIMEI Tool for Unisoc to restore it. The video guide below shows the exact steps.

Tecno Pop 5 LTE BD4 Flashing FAQ
Q1: What if the flash fails halfway through?
A: Do not panic and do not disconnect the phone. Close SPD Research 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: 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 Unisoc devices, use the WriteIMEI Tool. Do not insert a SIM card until the IMEI is restored.
Q3: Will flashing erase my data?
A: Yes, flashing with SPD Research Tool restores the device to factory state, including Android 11, HIOS 7.6 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.
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: Is this firmware compatible with other Tecno models?
A: No. This firmware is built specifically for the Tecno Pop 5 LTE BD4 running on the Unisoc SC9863A chipset. Even variants of the Pop 5 LTE 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: 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 SPD Research Tool appears stuck, give it a few more minutes before assuming something went wrong.
Q7: 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.
Q8: My device is not detected by SPD Research Tool. What should I do?
A: Start with the drivers, reinstall the Spreadtrum USB 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.
