The Infinix Smart 10 Plus X6725B firmware package is different from MediaTek devices because it relies on a single `.pac` file rather than multiple partitions. Selecting the correct file is the most common point of failure for users attempting a repair. The Infinix Smart 10 Plus X6725B firmware package is different from MediaTek devices because it relies on a single `.pac` file rather than multiple partitions. Selecting the correct file is the most common point of failure for users attempting a repair. The Infinix Smart 10 Plus X6725B is a relatively recent device, so you should expect active firmware updates and good driver support on modern Windows systems. There are 2 firmware files available for the Infinix Smart 10 Plus X6725B on this page. Pick the one that matches your current Android version for the smoothest flash. The Infinix Smart 10 Plus X6725B uses a Unisoc T7250 (Octa-core: 2x 1.8 GHz Cortex-A75 & 6x 1.6 GHz Cortex-A55) 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.

Which Firmware Version Should I Download?
Choosing the right file from the download table depends on the specific issue your Infinix Smart 10 Plus X6725B is experiencing.
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | 15.1.0.108SP02(OP001PF001AZ).rar, download this one. It is the latest Infinix Smart 10 Plus X6725B 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 15.1.0.108SP02(OP001PF001AZ).rar first, then follow the IMEI repair guide. Do not skip the reflash. |
| 15.1.0.108SP02(OP001PF001AZ).rar 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 | 15.1.0.108SP02(OP001PF001AZ).rar, 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.

Infinix Smart 10 Plus X6725B Flash Setup Checklist
Proper preparation before flashing the Infinix Smart 10 Plus X6725B firmware ensures a successful operation and prevents common connection errors.
- 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:
- Infinix USB Drivers (includes Spreadtrum USB drivers)
Step-by-Step: Flash Infinix Smart 10 Plus X6725B Stock ROM
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.
- Prepare the Flash Files:
- Go to the download section and grab the firmware package that matches your device.
- Unzip the file to a folder on your desktop. Avoid using folder names with non-English characters or spaces, the flash tool may not read them correctly.
- Confirm Driver Setup:
- The drivers listed in prerequisites need to be installed and working before you connect the phone. If you are not sure, reinstall them and restart your computer.
- 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:
- Click “Start” to kick off the firmware write.
- Hands off the phone and cable until the tool shows completion. Moving or disconnecting the device mid-flash is the most common cause of a bricked phone.
- Wait and Reboot:
- When you see the success message, disconnect the USB cable.
- Hold the power button to boot the phone. Give it a solid 5 to 8 minutes for the first startup, this is normal.

What to Do if Infinix Smart 10 Plus X6725B Flash Fails
- Infinix Smart 10 Plus X6725B 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 X6725B, 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 X6725B:
- 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 10 Plus X6725B 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.
What Is Normal After a Infinix Smart 10 Plus X6725B Flash?
After a successful flash of the Infinix Smart 10 Plus X6725B, you should expect a longer than usual first boot time and a fresh setup process.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Missing IMEI or Corrupt Baseband on Infinix Smart 10 Plus X6725B 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.

Questions About Infinix Smart 10 Plus X6725B Firmware
Q1: 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.
Q2: 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.
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: 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.
Q5: 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.
Q6: 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.
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 10 Plus X6725B running on the Unisoc T7250 (Octa-core: 2x 1.8 GHz Cortex-A75 & 6x 1.6 GHz Cortex-A55) chipset. Even variants of the Smart 10 Plus 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.
