Infinix Smart 8 X6525 Firmware (Flash File) Drivers, Tools & Guide
I have been following the releases for this specific model, and the most common problem with Unisoc phones is not the flash process itself, but selecting the wrong .pac file and wondering why SPD Research Tool throws an error. This guide provides the solution. Everything you need is on this page: the correct firmware, the right tool, and the exact steps to follow.
Before you start, understand that 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.
You will find three firmware files available for the Infinix Smart 8 X6525 on this page. Pick the one that matches your current Android version for the smoothest flash. The stock firmware ships with Android 13 Go edition, which determines the default apps, security features, and interface you will see after flashing. The Infinix Smart 8 X6525 uses a Unisoc T606 chipset (Unisoc/Spreadtrum), so you will need SPD Flash Tool and SPD USB drivers. These tools are specific to Unisoc-based devices and will not work with MediaTek or Qualcomm phones.
The Infinix Smart 8 X6525 was released in 2023. This page is maintained with the latest available firmware builds as they become available. We verified firmware file integrity across two independent sources to confirm these are authentic, unmodified stock ROMs.
Your Infinix Smart 8 X6525 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.
How to Wipe Infinix Smart 8 X6525 to Factory Settings
To factory reset Infinix Smart 8 X6525 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 Infinix Smart 8 X6525 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.
Remove FRP Lock on Infinix Smart 8 X6525
The fastest way to bypass FRP on Infinix Smart 8 X6525 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.
When Should You Flash Infinix Smart 8 X6525?
The Infinix Smart 8 X6525 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:
- Fix startup loops, lagging, and freezing on your device.
- Resolve OTA update failures and battery drain issues.
- Remove persistent malware or adware that survives a factory reset.
- Clear a forgotten screen lock, PIN, or pattern without needing the original credentials.
- Unlock your device if it has been locked or disabled.
- Restore system apps that were accidentally removed or corrupted.
- Resolve .pac loading failures and communication errors in SPD Research Tool that prevent normal use of your device.

How to Pick the Correct Infinix Smart 8 X6525 Firmware
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 “X6525”, not a similar name, the exact code.
- Match the Chipset: This firmware is built for Unisoc T606. 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 Smart 8 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.
Firmware Details for Infinix Smart 8 X6525
Here is a quick overview of the official firmware specifications:
| Firmware Information | Details |
|---|---|
| Device Model | Infinix Smart 8 X6525 |
| Firmware Version | V67, V119, V893 |
| File Size | 3.1 GB to 3.3 GB |
| Android Version | Android 13 Go edition |
| Platform | Unisoc T606 |
| Release Date | Released 2023, November 09 |
| Region | Global, Africa and Asia |
| File Type | ZIP (Contains .pac firmware file for SPD Research Tool) |
Which Firmware Version Should I Download?
You should pick the firmware based on the specific problem you are facing. 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 | V893, download this one. It is the latest Infinix Smart 8 X6525 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 V119, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V893 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V893 failed with a flash error | Try V119 instead and double-check your .pac file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V893, 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 Infinix Smart 8 X6525 Firmware
You can download the official stock firmware for the Infinix Smart 8 X6525 from the links below. The latest available version is V893. 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.

Important: The Infinix Smart 8 X6525 (X6525) should not be confused with other Smart 8 variants that may have different chipsets or regional firmware. Even devices in the same Smart 8 line can use completely different processors. Always verify your exact model code “X6525” in Settings > About Phone before downloading any firmware from this page.
- Go to Settings and verify your model is exactly X6525. Phones with similar names can have completely different hardware.
- The chipset in your device should be Unisoc T606. If it is different, this firmware will not work.
- Always download directly from the table on this page to ensure you have the correct build.
- Check the file size after downloading, a mismatch with the listed size means a partial or corrupt download.
Before You Start: Infinix Smart 8 X6525 Requirements
You must prepare your computer and drivers before attempting the flash. The most common reason Infinix 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:
- Infinix USB Drivers (includes Spreadtrum USB drivers)
How to Install Firmware on Infinix Smart 8 X6525
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.
Video Guide for Flashing
What to Expect After Flashing
After a successful flash, your phone will look and behave like a new device.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Infinix Smart 8 X6525 Flashing Problems and Fixes
- Infinix Smart 8 X6525 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 X6525, 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 X6525:
- 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 Infinix Smart 8 X6525 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 Infinix Smart 8 X6525 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.

Frequently Asked Questions
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 Infinix 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: 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.
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: 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: 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.
Q8: Is this firmware compatible with other Infinix models?
A: No. This firmware is built specifically for the Infinix Smart 8 X6525 running on the Unisoc T606 chipset. Even variants of the Smart 8 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.
