Tecno Pop 5 BD1 Firmware (Flash File) Drivers, Tools & Guide
You can fix your Tecno Pop 5 BD1 by using the official Tecno Pop 5 BD1 firmware. This page contains everything you need: the correct flash files, drivers, and detailed steps to resolve software issues.
The most common issue people face when working with Unisoc devices is selecting the wrong file type. If you pick the wrong .pac file, SPD Research Tool will throw an error, and you will waste time trying to figure out why the flash is failing. This guide is here to help you avoid that mistake.
One important detail about this device: the firmware package is a single .pac file, not a folder of separate partitions like you see on MediaTek phones. Make sure your downloaded ZIP file actually contains that .pac file before you open the flash tool. A lot of time gets wasted loading an empty or partially downloaded archive.
The Tecno Pop 5 BD1 uses a Spreadtrum SC7731E chipset (Unisoc), so you will need SPD Flash Tool and the corresponding USB drivers. These tools are specific to Unisoc-based devices and will not work with MediaTek or Qualcomm phones. The stock firmware ships with Android 10 (Go edition), HIOS, which determines the default apps, security features, and interface you will see after flashing. This page lists 18 firmware builds for the Tecno Pop 5 BD1, covering multiple Android versions and security patch levels. If one build does not work, try a different version.
We verified the firmware file integrity across two independent sources to confirm these are authentic, unmodified stock ROMs. As a Transsion Holdings brand, Tecno devices share similar chipset architectures and flashing procedures across the Pop 5 lineup.
Your Tecno Pop 5 BD1 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 .pac file before proceeding.
Keep in mind that flashing stock firmware erases all data, which is intentional, as it resolves software issues including FRP lock, app problems, slow performance, forgotten pattern locks, a dead or logo-stuck device, Wi-Fi and Bluetooth issues, battery drain, and soft brick situations.
Hard Reset Tecno Pop 5 BD1
To perform a factory reset on the Tecno Pop 5 BD1 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 BD1 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.
Bypass Google Lock on Tecno Pop 5 BD1
The quickest method to bypass the Google account lock on Tecno Pop 5 BD1 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 Pop 5 BD1 Firmware?
You need the Tecno Pop 5 BD1 firmware to fix software problems that a simple reset cannot resolve. The device runs on a Unisoc (Spreadtrum) chipset, and the most reliable way to fix software issues on these devices is a clean firmware flash using SPD Research Tool. Here is what the stock firmware can fix:
- Restore system apps that were accidentally removed or corrupted.
- Update to the latest Android version supported by your phone.
- Repair a phone that shuts down randomly or restarts in a loop.
- Resolve OTA update failures and battery drain issues.
- Remove persistent malware or adware that survives a factory reset.
- Restore the original Tecno stock ROM to keep your warranty valid.
- Resolve .pac loading failures and communication errors in SPD Research Tool that prevent normal use of your device.

Verify Your Tecno Pop 5 BD1 Model Before Downloading
Before downloading the Tecno Pop 5 BD1 firmware, you must confirm that your device model is exactly BD1 and not another variant. The single biggest mistake I see people make is flashing firmware meant for a different variant.
- Open About Phone: Your device model must read “BD1” exactly. Even small differences in the code can mean a completely different chipset and partition layout.
- Verify the Chipset Type: This firmware targets Spreadtrum SC7731E 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.

Which Firmware Version Should I Download?
To choose the right file, compare your current phone condition with the situations listed in the table below:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V18, download this one. It is the latest Tecno Pop 5 BD1 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 BD1 (BD1) should not be confused with other Pop 5 variants that may have different chipsets or regional firmware. Even devices in the same Pop 5 line can use completely different processors. Always verify your exact model code “BD1” in Settings > About Phone before downloading any firmware from this page.
- Open About Phone and make sure the model code reads BD1. Do not rely on the name printed on the phone case.
- Verify the chipset is Spreadtrum SC7731E. You can see this in recovery mode or by checking the device specifications online.
- Use only the download links provided on this page.
- After downloading, right-click the file and check Properties to confirm the size matches the table above. If it does not, download it again.
Tecno Pop 5 BD1 Flash Setup Checklist
Before starting the flash process, ensure you have completed all the necessary preparations on your computer. 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.
- Write Down Your IMEI: Open your phone dialer and type *#06#. Take a photo of the screen showing both IMEI numbers. You may need these later to fix your IMEI if it gets wiped during the flash.
- Sign Out of Google: Open Settings, go to Accounts, and remove every Google account from the device. If you skip this, Google will lock the phone after flashing and you will need to do an FRP bypass.
- Save Your Files: Copy everything important to a PC or cloud storage. After flashing, the phone will be completely empty, no apps, no photos, no messages.
- Battery Check: Charge to at least 50%. If the phone dies during flashing, you could end up with a device that will not turn on at all.
- Get the Right Cable: You need a USB data cable, the kind that can transfer files, not just charge. Plug it into a USB 2.0 port on a Windows PC for the most reliable connection.
- Set Up Drivers:
- Tecno USB Drivers (includes Spreadtrum USB drivers)
How to Install Firmware on Tecno Pop 5 BD1
You can install the Tecno Pop 5 BD1 firmware using the SPD Research Tool by following these steps. 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.
- Get the Firmware Ready:
- Download the firmware file from the download section above.
- Right-click the ZIP and select “Extract Here” or use 7-Zip. Put the extracted files in a folder without spaces in the name, like
C:firmware.
- Verify Your Drivers:
- Make sure the required drivers are installed. After installing, restart your PC, drivers often do not activate until after a reboot.
- 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:
- Hit the “Start” button in the flash tool to start the process.
- Leave the phone and cable completely alone until it finishes. Any interruption during this stage risks corrupting the flash.
- Wait and Reboot:
- When the flash completes, unplug the USB cable from your phone.
- Turn on the device. First boot takes 3 to 8 minutes, do not force restart it during this time.
Video Guide for Flashing
What Is Normal After a Tecno Pop 5 BD1 Flash?
Several things are normal after flashing the Tecno Pop 5 BD1 firmware, including a warm phone and a long first boot time.
- 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 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.
- 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.
- 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.
- 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.
- 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.
Tecno Pop 5 BD1 Flashing Problems and Fixes
- Tecno Pop 5 BD1 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 BD1, 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 BD1:
- 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 BD1 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.
Missing IMEI or Corrupt Baseband on Tecno Pop 5 BD1 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.

Common Questions About Flashing Tecno Pop 5 BD1
Q1: 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.
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: 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.
Q4: 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.
Q5: Is this firmware compatible with other Tecno models?
A: No. This firmware is built specifically for the Tecno Pop 5 BD1 running on the Spreadtrum SC7731E chipset. Even variants of the Pop 5 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: 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.
Q8: Will flashing erase my data?
A: Yes, flashing with SPD Research 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.
