Infinix Hot 10i PR652B Firmware (Flash File) Drivers, Tools & Guide
This guide covers the official stock ROM for the Infinix Hot 10i PR652B, the necessary drivers, and the steps to restore the device to factory condition.
The Infinix Hot 10i PR652B firmware is built for a Unisoc chipset, which requires a specific approach compared to other brands. The main issue users face is selecting the correct file type. Unlike MediaTek devices that use multiple partitions, Unisoc phones rely on a single .pac file. If you try to load a generic file, the SPD Research Tool will not work. This guide ensures you have the right file and the correct tool to complete the process.
Before starting, ensure the downloaded ZIP file actually contains the .pac file. A corrupted or incomplete download will cause the flash tool to fail. The stock firmware for the Infinix Hot 10i PR652B comes with Android 11 and XOS 7.5 pre-installed. This version determines the user interface and security features you will see after the flash is complete.
This process wipes the device completely, returning it to the state it was in when you first bought it. This clean slate is often the only way to fix persistent bugs, bootloops, or locked screens. We have verified the integrity of these files through multiple sources to ensure they are authentic stock ROMs.
To use the files, you must extract the ZIP archive using WinRAR or 7-Zip. Once extracted, locate the .pac file within the folder before proceeding to the installation steps.
Factory Reset Infinix Hot 10i PR652B Without a PC
To perform a factory reset on the Infinix Hot 10i PR652B without connecting to a computer, power off the device, then hold the Volume Up and Power buttons simultaneously until the recovery menu appears.
A hard reset erases all user data and restores the Infinix Hot 10i PR652B to its original factory settings. This action resolves many common software issues, including lag, app crashes, forgotten screen locks, and bootloops. If the problem persists after a reset, a full firmware flash using SPD Research Tool is required.
Remove FRP Lock on Infinix Hot 10i PR652B
The fastest method to bypass the Google FRP lock on the Infinix Hot 10i PR652B involves using a third-party Android launcher app that grants access to the settings menu during the initial setup wizard.
After flashing or performing a factory reset, you may encounter the Google account verification screen. Our free Android apps launcher is designed to help you navigate past this screen. It is always recommended to remove your Google account before flashing to avoid this situation entirely.

How to Pick the Correct Infinix Hot 10i PR652B Firmware
Selecting the wrong firmware version is the primary cause of flashing errors on this device, so verifying your device identity before downloading is essential.
- Check About Phone: Open Settings and find your exact model number. It should read “PR652B”, not a similar name, the exact code.
- Match the Chipset: This firmware is built for Unisoc SC9863A. 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 Hot 10i 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?
To determine which firmware file you need, compare your current device status with the scenarios listed in the table below.
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V76, download this one. It is the latest Infinix Hot 10i PR652B 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 V036, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V76 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V76 failed with a flash error | Try V036 instead and double-check your .pac file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V76, 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.

Important: The Infinix Hot 10i PR652B (PR652B) should not be confused with other Hot 10i variants that may have different chipsets or regional firmware. Even devices in the same Hot 10i line can use completely different processors. Always verify your exact model code “PR652B” in Settings > About Phone before downloading any firmware from this page.
- Your model number is a variant of PR652B with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.
- Your chipset differs from Unisoc SC9863A. Confirm in recovery mode before proceeding.
- You downloaded the file from a source other than this page.
- The file size differs significantly from the sizes listed in the table above, a size mismatch usually means a partial download, which will fail mid-flash.
Prerequisites for Infinix Hot 10i PR652B Firmware
Before attempting to flash the Infinix Hot 10i PR652B, ensure you have completed the necessary preparation steps listed below.
- IMEI Backup: Open the dialer and enter *#06#. Write both IMEI numbers down on paper or take a screenshot. If you ever need to repair your IMEI after flashing, these are essential.
- Remove All Google Accounts: Go to Settings, Accounts, and sign out of every Google account on the device. Leaving accounts signed in triggers FRP lock after a flash, which blocks you from setting up the phone.
- Backup Everything: Photos, contacts, messages, WhatsApp data, move it all to a computer or cloud service. The flash will restore the phone to factory state with nothing on it.
- 50% Battery Minimum: Do not start with a low battery. If power cuts out during the flash, the device can become unresponsive and much harder to fix.
- USB Cable and Computer: Use a proper data-transfer USB cable and a Windows PC. Avoid USB hubs, connect directly to the motherboard port for a stable connection.
- Download and Install Drivers:
- Infinix USB Drivers (includes Spreadtrum USB drivers)
How to Install Firmware on Infinix Hot 10i PR652B
We are using the SPD Research Tool for this. It is the standard software for handling Unisoc-based devices. One important step is to run the tool as Administrator. Right-click the .exe file and select “Run as administrator.” This prevents permission errors. You can also follow the video guide below if you prefer visual instructions.
- 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 Is Normal After a Infinix Hot 10i PR652B Flash?
Several behaviors are normal immediately following a successful firmware flash on the Infinix Hot 10i PR652B.
- 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.
- 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.
- All your apps are gone, this is expected. Reinstall them from the Play Store. If you had a Google account backup active, it will offer to restore your apps automatically during setup.
- 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.
- 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.
- 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.
- 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.
Fix Common Infinix Hot 10i PR652B Firmware Errors
- Infinix Hot 10i PR652B 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 PR652B, 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 PR652B:
- 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 Hot 10i PR652B 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 Hot 10i PR652B 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.

Infinix Hot 10i PR652B Firmware 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: 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: 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.
Q4: 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.
Q5: 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 SPD Research Tool appears stuck, give it a few more minutes before assuming something went wrong.
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: 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.
Q8: 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.
