Tecno Pop 5 LTE BD4 Firmware (Flash File) Drivers, Tools & Guide
To restore your Tecno Pop 5 LTE BD4 to full working order, you will need the correct Tecno Pop 5 LTE BD4 firmware, the right flashing tool, and proper drivers. The most common problem I see with Unisoc-powered phones is not the flashing process itself, but rather selecting an incorrect .pac file, which then causes errors in SPD Research Tool. This guide walks you through each step to avoid those issues.
A quick note before you dive in: firmware packages for Unisoc devices, unlike MediaTek, come as a single .pac file, not a collection of separate partition files. Always check that your downloaded ZIP archive actually contains this .pac file before you try to load it into the flash tool. This small check can save a lot of frustration from trying to load an incomplete or corrupt download.
Your Tecno Pop 5 LTE BD4 firmware arrives as a compressed ZIP file. Make sure to download it, then extract the contents using WinRAR or 7-Zip. After extraction, open the resulting folder and confirm the .pac file is present before you move forward.
Remember that installing stock firmware will erase all data on your device. This is by design, as it helps to fully resolve common software problems like FRP locks, application glitches, sluggish performance, forgotten screen patterns, devices stuck on the logo or completely unresponsive, Wi-Fi and Bluetooth connectivity issues, excessive battery drain, and soft brick situations.
Hard Reset Tecno Pop 5 LTE BD4
You can factory reset your Tecno Pop 5 LTE BD4 without needing a computer by completely turning off the device, then simultaneously pressing and holding the Volume Up and Power buttons until the recovery menu appears. From there, navigate to “Wipe Data/Factory Reset” using the volume keys and confirm your selection with the Power button.
Performing a hard reset will wipe all data and return your Tecno Pop 5 LTE BD4 to its initial factory settings. This step often resolves many software-related problems such as slow operation, app crashes, forgotten screen locks, and bootloops. If the issue persists after a factory reset, a complete firmware flash using SPD Research Tool, as detailed in the next sections, will be necessary.
Tecno Pop 5 LTE BD4 FRP Bypass
The most efficient method to bypass FRP on a Tecno Pop 5 LTE BD4 involves utilizing a free Android apps launcher that allows access to device settings during the initial setup process. After either flashing the firmware or performing a factory reset, you might encounter a Google account lock, also known as FRP. Our free Android apps launcher provides the quickest way around this. 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 LTE BD4 Firmware?
We often need Tecno Pop 5 LTE BD4 firmware because this phone uses a Unisoc (Spreadtrum) chipset, and a clean firmware flash with SPD Research Tool is the most dependable way to resolve its software problems. Here is what flashing stock firmware can help fix:
- Unlock devices that are locked or have been disabled.
- Install the most current Android version supported by your phone model.
- Address issues such as startup loops, system lag, and freezing on your BD4 Pop 5 LTE.
- Correct problems with OTA updates failing or unusual battery drain.
- Revert to the original Tecno stock ROM, which helps maintain warranty status.
- Restore functionality to your device if it only starts in recovery mode.
- Fix .pac file loading errors and communication problems within SPD Research Tool, which prevent normal device use.
Learn more about stock ROMs and why flashing works.
Choosing the Right Firmware Version
Before proceeding with any flashing, it is crucial to confirm that you have selected the correct firmware file. Flashing incompatible firmware can lead to a device state that is very hard to recover from.
- Verify your device model: Navigate to About Phone on your device and ensure the model is indeed Tecno Pop 5 LTE BD4. Look for the complete model string, not just the general name.
- Check the build number: Find the identifier “BD4” within your device’s build details.
- Confirm the device chipset: According to Tecno specifications, the Pop 5 LTE BD4 uses the Unisoc SC9863A chipset.
- Match the firmware version and region: Compare the version and regional information with what is provided in the download table below.
- Verify details in recovery mode: If you are uncertain about the chipset or build number, booting into recovery mode will clearly display this information, making it the most reliable way to confirm before you flash.

Which Firmware Version Should I Download?
This is a frequent question in the comments section, so I have prepared a straightforward guide. Locate your current situation in the table provided and select the appropriate firmware 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. |
When working with Unisoc devices, I typically suggest starting with the newest .pac file. Older SPD Research Tool firmware versions can sometimes lead to modem-related issues, which might manifest as a “no signal” problem after flashing. Only attempt an older version if the latest one does not successfully resolve your issue.

Only download firmware that is fully compatible with your exact device model. If you are uncertain, please consult the firmware selection guide above.
- Your device model number is a variant of BD4 that includes a different letter suffix. Check About Phone carefully, even one letter difference can cause a failed or broken flash.
- Your device’s chipset is not the Unisoc SC9863A. Confirm this in recovery mode before proceeding.
- The firmware file was obtained from any source other than this particular page.
- The downloaded file size is notably different from the sizes provided in the table above, a size mismatch usually means a partial download, which will fail mid-flash.
Prerequisites for Tecno Pop 5 LTE BD4 Firmware
Before you do anything else, and I mean even before you download the Tecno Pop 5 LTE BD4 firmware, review this list carefully. The most common reason why Tecno Unisoc device flashes fail is neglecting the driver installation. SPD Research Tool is quite specific about its drivers, and Windows does not always clearly indicate when they are missing.
- Record IMEI Numbers: Dial *#06# on your phone and write down both IMEI numbers now. You will require these if you need to restore your IMEI after the flashing process.
- Sign out of Google Accounts: Log out of all Google accounts on your device to prevent an FRP lock from activating after flashing.
- Create a Data Backup: Back up all your important data, including photos, contacts, WhatsApp chats, and any other critical files. Flashing will completely wipe the device.
- Ensure Device is Charged: Your device should have at least 50% battery charge. A phone that powers off during a flash can be very difficult to recover.
- Prepare USB Cable and PC: Use a high-quality data USB cable, not a cable meant only for charging, and ensure you have a Windows computer with accessible USB ports.
- Install Necessary Drivers:
- Tecno USB Drivers (this package includes Spreadtrum USB drivers)
How to Install Firmware on Tecno Pop 5 LTE BD4
We will be using the SPD Research Tool for this procedure, as it is the standard application for Unisoc-based devices. One practice I always follow is running it as Administrator; right-click the .exe file and select “Run as administrator.” This simple step helps avoid many common permission-related errors. If you prefer to watch the process, a video guide is available below.
- Download and Extract:
- Get the correct firmware package using the download links provided.
- Unpack the ZIP file to a straightforward folder location; it is best to avoid paths that contain spaces or special characters, as some flashing tools can have issues with them.
- Install the Listed Drivers:
- Confirm that all prerequisite drivers are installed and that your computer has been restarted after installation. Not restarting is a frequent cause of driver malfunction.
- Load the Firmware File:
- Select the “Load Packet” button, then browse to the extracted folder and choose the .pac firmware file.
- Connect Your Device:
- Completely power down your phone; ensure it is fully off, not just in sleep mode.
- Connect the device to your computer using a USB cable. The flashing tool should automatically recognize it.
- Start Flashing:
- Press the “Start” button to begin the flashing process.
- Do not disconnect the cable, move it, or interact with the device until the process shows as fully completed. Interrupting the flash can render your device unusable.
- Wait and Reboot:
- After the flashing finishes successfully, you may disconnect the device.
- Turn on your device. The initial startup will take longer than usual, sometimes up to 8 minutes.

What to Expect After Flashing Tecno Pop 5 LTE BD4 Firmware
I often hear from people who are concerned that something went wrong when it actually did not. Do not worry; here is what you can consider completely normal after a successful Tecno Pop 5 LTE BD4 firmware flash:
- Successful flash indication: The SPD Research Tool will display a green “PASSED” message once the flash is completed. Seeing this means you have finished.
- Initial boot duration: The first startup can take between 3 and 8 minutes. Do not try to force a reboot during this time. The operating system is configuring itself anew, and interruption can lead to bootloop issues.
- Device warmth during first boot: It is normal for the phone to feel warm during its first startup. This sensation will subside after a few minutes once the initial application setup is done.
- Loss of applications: All your previously installed applications will be removed, which is part of the process. You can reinstall them from the Play Store. If you had an active Google account backup, the device will offer to restore your apps automatically during the initial setup.
- IMEI check: Dial *#06# right after completing the setup to verify your IMEI. Make sure to do this before inserting a SIM card. If the IMEI shows as “unknown” or “null”, proceed with the IMEI repair guide provided further down this page before taking any other steps.
- Google account re-addition: Exercise caution when adding your Google account back. If you did not remove it prior to flashing, you might encounter an FRP (Factory Reset Protection) prompt. It is best to add your account during the initial setup wizard, rather than later through the settings menu.
- Connectivity (Wi-Fi, Bluetooth, mobile data): All these should function correctly immediately after setup. If mobile data does not connect, navigate to Settings › SIM and Network to manually input your APN settings again, as the flashing process can occasionally clear carrier APN configurations.
- Bootloop after first startup: Should your device get stuck in a bootloop after the initial power-on, enter recovery mode and perform a factory reset from there; refer to the hard reset guide above. This can happen sometimes and does not indicate a faulty firmware; it usually points to a conflict with residual data from the previous software installation.
- Pre-installed HiOS / XOS applications: Upon flashing Tecno Pop 5 LTE BD4 firmware, you will find pre-installed Tecno applications. These can be disabled via Settings › Apps if you prefer not to use them, but avoid forcefully removing them using ADB, as some are integral to essential system services on your phone.
Missing IMEI or Corrupt Baseband on Tecno Pop 5 LTE BD4 After Flashing?
If you find your IMEI missing after a Unisoc flash, it usually means the NVRAM partition was not written correctly during the process. I have been there; this happens more often than it should with SPD devices. The WriteIMEI Tool handles this particular issue well for Unisoc chipsets. Just make certain you had your original IMEI recorded before you flashed; remember to dial *#06# next time. Without that original number, proper restoration is not possible.
You will need the WriteIMEI Tool for Unisoc to restore it. The video guide below demonstrates the precise steps.

Common Issues When Flashing Tecno Pop 5 LTE BD4
When flashing your Tecno Pop 5 LTE BD4, you might run into a few common issues. Here are some of those problems and their usual solutions:
- Tecno Pop 5 LTE BD4 Not Recognized by SPD Research Tool:
- Usually, this indicates a driver problem rather than an issue with the USB cable. Reinstall the Spreadtrum USB drivers for the BD4, reboot your computer, and then try connecting the device once more.
- If the phone remains undetected, attempt using a different USB port. USB 2.0 ports generally offer more dependable connections for Unisoc devices compared to USB 3.0.
- Consider temporarily disabling your antivirus software. It can occasionally prevent the Spreadtrum driver from loading correctly without providing any explicit error messages.
- Boot Loop After Flashing:
- Access recovery mode and complete a factory reset. This action typically fixes the majority of bootloops that occur after flashing on Unisoc devices. Should recovery mode also be inaccessible, perform the firmware reflash from the beginning.
- Wrong .pac File Selected for BD4:
- An immediate error from SPD Research Tool after loading the file often means you have chosen the incorrect firmware. Double-check that the .pac file’s model code corresponds precisely with your Tecno Pop 5 LTE BD4.
- No Signal After Flashing:
- This problem typically indicates an issue with the IMEI. Dial *#06#; if the result is ‘null’ or ‘unknown’, proceed with the IMEI repair guide mentioned earlier on this page before attempting to insert your SIM card.
