Tecno Pouvoir 3 Plus LB8a Firmware (Flash File) Drivers, Tools & Guide
I have worked with Tecno phones for a long time, and the Tecno Pouvoir 3 Plus LB8a is one I see frequently. It usually arrives with bootloops, stuck logos, or FRP lock problems. This guide puts the firmware, tools, and process in one place for you.
One thing I always recommend before you start: extract the firmware to a simple folder path, something like C:FirmwareLB8a. SP Flash Tool can sometimes have trouble locating the scatter file if the folder path contains spaces or special characters. It is a small thing, but it saves a frustrating few minutes of wondering why the tool is not loading the file.
There are 3 firmware files available for the Tecno Pouvoir 3 Plus LB8a on this page. Pick the one that matches your current Android version for the smoothest flash. The stock firmware ships with Android 9.0 (Pie), HIOS 5.0, which determines the default apps, security features, and interface you will see after flashing. The Tecno Pouvoir 3 Plus LB8a was originally released in 2019, which means USB driver compatibility on newer Windows versions (10/11) may require manual installation rather than plug-and-play.
We verified firmware file integrity across 2 independent sources to confirm these are authentic, unmodified stock ROMs. The Tecno Pouvoir 3 Plus LB8a was released in 2019. This page is maintained with the latest available firmware builds as they become available.
Your Tecno Pouvoir 3 Plus LB8a 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 scatter file before proceeding.
Once you flash, the device goes back to factory condition. Everything stored on the phone, photos, messages, apps, will be gone. This clean state is what allows the flash to fix stuck logos, FRP locks, software corruption, and performance issues.
How to Wipe Tecno Pouvoir 3 Plus LB8a to Factory Settings
To reset your Tecno Pouvoir 3 Plus LB8a to factory settings without a computer, you must 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 Pouvoir 3 Plus LB8a 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 SP Flash Tool is covered in the following sections.
Bypass Google Lock on Tecno Pouvoir 3 Plus LB8a
The fastest way to bypass FRP on Tecno Pouvoir 3 Plus LB8a 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 Pouvoir 3 Plus LB8a Firmware?
The Tecno Pouvoir 3 Plus LB8a uses a MediaTek chipset, and SP Flash Tool is the standard method for firmware recovery on MTK devices. Here is what flashing the stock firmware can help with:
- Remove persistent malware or adware that survives a factory reset.
- Repair a phone that shuts down randomly or restarts in a loop.
- Resolve OTA update failures and battery drain issues.
- Fix Wi-Fi, Bluetooth, or mobile data connectivity that stopped working after an update.
- Update to the latest Android version supported by your phone.
- Unlock your device if it has been locked or disabled.
- Recover from “Download DA FAIL” errors and Secure Boot authentication issues specific to the MediaTek chipset in your device.
Learn more about stock ROMs and why flashing works.
Choosing the Right Firmware Version
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 “LB8a” exactly. Even small differences in the code can mean a completely different chipset and partition layout.
- Verify the Chipset Type: This firmware targets MediaTek MT6762 Helio P22 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.

| File Type | ZIP (Includes Scatter File [MT6xxx_Android_scatter.txt], preloader.bin, boot.img, system.img, recovery.img, lk.bin, logo.bin, nvram.img, and more) |
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 | V147, download this one. It is the latest Tecno Pouvoir 3 Plus LB8a 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 V128, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V147 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V147 failed with a flash error | Try V128 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V147, 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.
Download Tecno Pouvoir 3 Plus LB8a Firmware
Download the official stock firmware for your Tecno Pouvoir 3 Plus LB8a below. The latest available version is V147. After downloading, verify the file size matches the table above, a size mismatch usually means a partial or corrupt download, and flashing a corrupt file can cause more problems than it solves.
| Software Details | Download Link | Members Link |
|---|---|---|
|
File Name: Tecno_Pouvoir_3_Plus_LB8A_MT6765_V147_190929.zip Size: 2.02 GB | Download Link | Download Link2 |
| File Name: Tecno Pouvoir 3 Plus LB8a (LB8a-H6113GH-P-190906V128).7z Size: 1.7 GB | Download Link | Download Link2 |
| File Name: Tecno Pouvoir 3 Plus LB8a (LB8a-H6113GH-P-IN-190929V147).7z Size: 1.7 GB | Download Link | Download Link2 |
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 Pouvoir 3 Plus LB8a (LB8a) should not be confused with other Pouvoir 3 Plus variants that may have different chipsets or regional firmware. Even devices in the same Pouvoir 3 Plus line can use completely different processors. Always verify your exact model code “LB8a” in Settings > About Phone before downloading any firmware from this page.
- The model code on your phone must match LB8a exactly. Even a single letter variant (like adding or dropping an “i” or “s”) can mean a different chipset inside.
- Your chipset should be MediaTek MT6762 Helio P22. Recovery mode shows this information if you are not sure.
- Do not mix firmware from other download sites with the files on this page.
- If the downloaded file is much smaller than what is listed in the table above, re-download it, partial files will fail.
Tecno Pouvoir 3 Plus LB8a Flash Setup Checklist
Do not skip this section. Most failed Tecno flashes come from rushing through the preparation steps. The VCOM driver installation is essential for the Tecno Pouvoir 3 Plus LB8a and other MediaTek devices. Windows may show the device in Device Manager and SP Flash Tool will still not detect it if the correct VCOM driver is not installed.
- 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:
Flashing Tecno Pouvoir 3 Plus LB8a Firmware With SP Flash Tool
We are using SP Flash Tool for this. For older devices, I recommend trying SP Flash Tool v5.1924 first. The newer versions of SP Flash Tool require a DA (Download Agent) file that older firmware packages do not include, and that is what causes the “Auth” errors you may have seen. If SP Flash Tool keeps asking for 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 below. The complete SP Flash Tool guide is also available if you need more detail.
- Download and Unpack:
- Pick the correct firmware version from the downloads above and save it to your PC.
- Extract the ZIP file. If the extracted folder contains another ZIP inside, extract that one too. You should end up with the actual firmware files, not another archive.
- Driver Check:
- Double-check that you have installed the required drivers. A missing driver is the most common reason the flash tool cannot detect your phone. Reboot your PC after installing.
- 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:
- Start the flash by clicking “Download”.
- Leave everything untouched until completion. Even bumping the USB cable can interrupt the write and cause a failed flash.
- Wait and Reboot:
- The flash is complete when the tool shows a success indicator. Disconnect your phone.
- Turn the phone on. Do not worry if it sits on the boot logo for several minutes, the system is rebuilding itself from scratch.
Post-Flash Behavior on Tecno Pouvoir 3 Plus LB8a
Here is what is completely normal after a successful flash:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Tecno Pouvoir 3 Plus LB8a Flashing Problems and Fixes
- Tecno Pouvoir 3 Plus LB8a Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the LB8a, 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.
Missing IMEI or Corrupt Baseband on Tecno Pouvoir 3 Plus LB8a 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.

Tecno Pouvoir 3 Plus LB8a Flashing FAQ
Q1: 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.
Q2: 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.
Q3: 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.
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: 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.
Q6: 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 MediaTek devices, SN Write Tool or Maui Meta will handle the repair. Do not insert a SIM card until the IMEI is restored.
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: 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.
