Tecno Pop 5S A571LS Firmware (Flash File) Drivers, Tools & Guide
The official stock ROM for the Tecno Pop 5S A571LS firmware is available below, complete with the necessary drivers and SPD Research Tool instructions. I have put everything here to help you get your device back to working order. ⚡ At a Glance Device: Tecno Pop 5S A571LS | Chipset: Unisoc (SPD) | Flash Tool: SPD Research Tool Android: Android 10 (Go edition), HiOS | File Type: ZIP (Contains .pac firmware file for SPD Research Tool) ⚠ Warning: Flashing erases all data. Back up first.
I have been tracking Tecno Pop 5S A571LS firmware releases for a while, and the most common issue with Unisoc devices is not the flashing itself, but selecting the wrong .pac file and then wondering why SPD Research Tool throws an error. This guide is here to fix that. Everything you need is on this page: the right firmware, the right tool, and the exact steps to follow.
One important thing before you start: the firmware package for Unisoc devices is a single .pac file, not a folder of separate partitions like you would see with MediaTek. Make sure your downloaded ZIP actually contains that .pac file before you open the flash tool. A lot of time gets wasted loading an empty or partially downloaded archive.
Only one firmware build is currently available for the Tecno Pop 5S A571LS firmware. This is the stock ROM you should use for recovery, unbricking, or FRP bypass. The stock firmware ships with Android 10 (Go edition), HiOS, which determines the default apps, security features, and interface you will see after flashing. The Tecno Pop 5S A571LS was originally released in 2022, which means USB driver compatibility on newer Windows versions (10/11) may require manual installation rather than plug-and-play.
The Tecno Pop 5S A571LS was released in 2022. This page is maintained with the latest available firmware builds as they become available. As a Transsion Holdings brand, Tecno devices share similar chipset architectures and flashing procedures across the Pop 5S lineup.
Your Tecno Pop 5S A571LS 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.
Flashing replaces your current software completely and wipes all personal data. This is by design, it is what clears out FRP locks, bootloops, pattern locks, app crashes, and other software-level problems that a regular reset cannot fix.
Hard Reset Tecno Pop 5S A571LS
To perform a hard reset on Tecno Pop 5S A571LS 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 5S A571LS 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.
FRP Removal for Tecno Pop 5S A571LS
The fastest way to bypass FRP on Tecno Pop 5S A571LS 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 5S A571LS Firmware?
The Tecno Pop 5S A571LS 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:
- Unlock your device if it has been locked or disabled.
- Repair a phone that shuts down randomly or restarts in a loop.
- Resolve touchscreen responsiveness issues caused by a corrupted system build.
- Restore system apps that were accidentally removed or corrupted.
- Resolve OTA update failures and battery drain issues.
- 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 5S A571LS Model Before Downloading
The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:
- Check About Phone: Open Settings and find your exact model number. It should read “A571LS”, not a similar name, the exact code.
- Match the Chipset: This firmware is built for Unisoc (SPD). If your device has a different processor, it will not flash correctly.
- Look at the Build Number: The build string in your current software should reference the Pop 5S line. Cross-check it with the firmware table below.
- Check Recovery Mode: Power off, hold Volume Up + Power until recovery appears. The screen displays your chipset and current build, use this to confirm.
- Compare File Details: Make sure the version listed in the download table matches what you expect for your device and region.

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 | V33, download this one. It is the latest Tecno Pop 5S A571LS 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 the next older version, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V33 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V33 failed with a flash error | Try the next older version instead and double-check your .pac file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V33, 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 5S A571LS Firmware
Download the official stock firmware for your Tecno Pop 5S A571LS below. The latest available version is V33. 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.

|---|---|---|
|
File Name: Tecno_Pop_5S_A571LS_MX_V33_230201_10_SPD.zip Size: 1.5 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 Pop 5S A571LS (A571LS) should not be confused with other Pop 5S variants that may have different chipsets or regional firmware. Even devices in the same Pop 5S line can use completely different processors. Always verify your exact model code “A571LS” in Settings > About Phone before downloading any firmware from this page.
- Open About Phone and make sure the model code reads A571LS. Do not rely on the name printed on the phone case.
- Verify the chipset is Unisoc (SPD). 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.
Prepare Your Tecno Pop 5S A571LS for Flashing
Before anything else, and I mean before you even download the Tecno Pop 5S A571LS 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)
How to Install Firmware on Tecno Pop 5S A571LS
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.
- 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.

Post-Flash Behavior on Tecno Pop 5S A571LS
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.
- 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.
- Wi-Fi, Bluetooth, and mobile data should all work right after setup. If mobile data is not connecting, go to Settings, SIM and Network, and re-enter your APN manually, the flash sometimes clears carrier APN settings.
- 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.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- 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.
- Stuck in a bootloop after first boot? Enter recovery mode and do a factory reset from there, see the hard reset guide above. This can happen occasionally and does not mean the firmware is wrong.
Fix Common Tecno Pop 5S A571LS Firmware Errors
- Tecno Pop 5S A571LS 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 A571LS, 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 A571LS:
- 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 5S A571LS 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 5S A571LS 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 5S A571LS
Q1: 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.
Q2: 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.
Q3: 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.
Q4: Is it safe to flash during a power outage risk?
A: It is best to avoid flashing during unstable power conditions. If your PC shuts down during the flash, it can corrupt the write and leave the phone in an unbootable state. If you are in an area with unreliable power, use a laptop with a fully charged battery instead of a desktop.
Q5: 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.
Q6: 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.
Q7: 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.
Q8: 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.
