How to Flash Tecno Pop 2 Plus RB8S Firmware Correctly
The main headache with Unisoc devices is picking the wrong .pac file. This guide provides the exact files and steps needed to fix the Tecno Pop 2 Plus RB8S.
One key detail about Unisoc firmware is that it is a single .pac file, not a collection of partitions like MediaTek. Always check your downloaded ZIP archive for this file before you open the flash tool.
The stock firmware ships with Android 9.0 Pie (Go edition), which determines the default apps, security features, and interface you will see after flashing. The Tecno Pop 2 Plus RB8S 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. There are 3 firmware files available for the Tecno Pop 2 Plus RB8S on this page. Pick the one that matches your current Android version for the smoothest flash.
With 3 firmware versions archived for the Tecno Pop 2 Plus RB8S, this page covers multiple Android builds and security patch levels. The Tecno Pop 2 Plus RB8S was released in 2019. This page is maintained with the latest available firmware builds as they become available.
Your Tecno Pop 2 Plus RB8S 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.
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.
Perform a Factory Reset on Tecno Pop 2 Plus RB8S Manually
To factory reset Tecno Pop 2 Plus RB8S 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 2 Plus RB8S 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 Bypass Google Lock on Tecno Pop 2 Plus RB8S
The fastest way to bypass FRP on Tecno Pop 2 Plus RB8S 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 You Need to Flash Stock Firmware on Tecno Pop 2 Plus RB8S
The Tecno Pop 2 Plus RB8S 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:
- Recover your device when it only boots into recovery mode.
- Fix startup loops, lagging, and freezing on your device.
- Remove persistent malware or adware that survives a factory reset.
- Resolve touchscreen responsiveness issues caused by a corrupted system build.
- Restore system apps that were accidentally removed or corrupted.
- Clear a forgotten screen lock, PIN, or pattern without needing the original credentials.
- Resolve .pac loading failures and communication errors in SPD Research Tool that prevent normal use of your device.

How to Select the Right Firmware for Tecno Pop 2 Plus RB8S
The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:
- Identify Your Device Model: Go to About Phone and confirm your model is Tecno Pop 2 Plus RB8S. Check the full model string, not just the name.
- Verify the Build Number: Look for the identifier “RB8S” in your device build details.
- Confirm the Chipset: According to Tecno specifications, the Pop 2 Plus RB8S runs on Unisoc (SPD).
- Match the Firmware Version: Check the version and regional details against what is listed in the download table above.
- Verify in Recovery Mode: If you are not sure about the chipset or build number, boot into recovery mode, it displays this information clearly and is the most reliable way to confirm before you flash.

How to Choose Between Tecno Pop 2 Plus RB8S Firmware Versions
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 | V09, download this one. It is the latest Tecno Pop 2 Plus RB8S 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 V07, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V09 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V09 failed with a flash error | Try V07 instead and double-check your .pac file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V09, 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.
Download Tecno Pop 2 Plus RB8S Firmware
Download the official stock firmware for your Tecno Pop 2 Plus RB8S below. The latest available version is V09. 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.

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 2 Plus RB8S (RB8S) should not be confused with other Pop 2 Plus variants that may have different chipsets or regional firmware. Even devices in the same Pop 2 Plus line can use completely different processors. Always verify your exact model code “RB8S” in Settings > About Phone before downloading any firmware from this page.
- Confirm your exact model is RB8S, check About Phone, not the marketing name on the box.
- Your device must have a Unisoc (SPD) 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.
Before You Start: Tecno Pop 2 Plus RB8S Requirements
Before anything else, and I mean before you even download the Tecno Pop 2 Plus RB8S 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.
- Record IMEI Before Flashing: Dial *#06# and save both IMEI numbers somewhere safe, a screenshot works. If flashing corrupts the baseband, these numbers are what you will need to restore cellular connectivity.
- Unlink Google Accounts: Go to Settings, then Accounts, and remove all Google accounts. This prevents Factory Reset Protection from activating after the flash. It is the single most skipped step and causes the most post-flash headaches.
- Full Data Backup: Flashing erases everything. Transfer your photos, contacts, app data, and any important files to your computer or cloud backup before starting.
- Charge the Battery: Make sure you have at least 50% charge. A dead battery during a flash can corrupt the system partition and turn a fixable problem into a much bigger one.
- Windows PC and USB Cable: You will need a Windows computer and a data-capable USB cable. Cheap charge-only cables are the number one reason flash tools fail to detect devices.
- Driver Installation:
- Tecno USB Drivers (includes Spreadtrum USB drivers)
Step-by-Step Guide to Flashing Tecno Pop 2 Plus RB8S Firmware
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 the Firmware Package:
- Use the download links in the table above to get the correct firmware file for your device.
- Extract the archive with WinRAR or 7-Zip. Use a short folder path like
D:flashto avoid issues with some tools.
- Check Drivers:
- All drivers from the prerequisites must be installed before connecting your device. Restart your computer after installing them.
- 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:
- Press “Start” to begin writing the firmware to your device.
- Do not unplug the phone, close the flash tool, or interact with the device until the process is 100% complete.
- Wait and Reboot:
- After the tool confirms the flash is complete, safely disconnect your phone.
- Press the power button to start your device. The initial boot is slow, wait up to 8 minutes before assuming there is a problem.

What to Expect After Flashing Tecno Pop 2 Plus RB8S 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.
- 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.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- Dial *#06# immediately after setup to check your IMEI. Do this before you insert a SIM card. If it shows “unknown” or “null”, follow the IMEI repair guide below before doing anything else.
- 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.
Troubleshooting Tecno Pop 2 Plus RB8S Flash Failures
- Tecno Pop 2 Plus RB8S 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 RB8S, 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 RB8S:
- 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 2 Plus RB8S 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.
Fixing IMEI Issues on Tecno Pop 2 Plus RB8S 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 Tecno Pop 2 Plus RB8S Firmware
Q1: 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.
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: Can I go back to an older firmware version?
A: It is technically possible on some Unisoc builds, but downgrading can cause security issues and app compatibility problems. If the latest version is causing trouble, leave a comment below, there is usually a better fix than rolling back.
Q4: 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.
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: 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.
Q7: 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.
Q8: 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.
