Infinix S4 X610B Firmware (Flash File) Drivers, Tools & Guide

I have repaired Infinix devices for a while now, and the Infinix S4 X610B comes in regularly, usually with FRP locks, bootloop issues, or stuck on the Infinix logo. This guide covers all of it. I have put everything you need in one place: the firmware, the tools, and the exact process I use myself.

One thing I always recommend before you start: extract the firmware to a simple folder path, something like C:FirmwareX610B. SP Flash Tool can sometimes have trouble locating the scatter file if the folder path contains spaces or special characters. It is a small thing, but it saves a frustrating few minutes of wondering why the tool is not loading the file.

There are 2 firmware files available for the Infinix S4 X610B on this page. Pick the one that matches your current Android version for the smoothest flash. The Infinix S4 X610B 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. The stock firmware ships with Android 9.0 (Pie), which determines the default apps, security features, and interface you will see after flashing.

The Infinix S4 X610B was released in 2019. This page is maintained with the latest available firmware builds as they become available. As a Transsion Holdings brand, Infinix devices share similar chipset architectures and flashing procedures across the S4 lineup.

Your Infinix S4 X610B 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 scatter file before proceeding.

Keep in mind that flashing stock firmware erases all data, which is intentional, as it resolves software issues including FRP lock, app problems, slow performance, forgotten pattern locks, a dead or logo-stuck device, Wi-Fi and Bluetooth issues, battery drain, and soft brick situations.

Hard Reset Infinix S4 X610B

You can perform a factory reset on the Infinix S4 X610B without a computer by accessing the recovery menu. 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 S4 X610B 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 SP Flash Tool is covered in the following sections.

Remove FRP Lock on Infinix S4 X610B

The most common way to get past the Google account lock on the Infinix S4 X610B is to use a launcher app 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 S4 X610B?

You should flash the stock firmware on the Infinix S4 X610B when software issues prevent the phone from working properly. The Infinix S4 X610B uses a MediaTek chipset, and SP Flash Tool is the standard method for firmware recovery on MTK devices. Here is what flashing the stock firmware can help with:

• Recover your device when it only boots into recovery mode.
• Resolve touchscreen responsiveness issues caused by a corrupted system build.
• Update to the latest Android version supported by your phone.
• Restore the original Infinix stock ROM to keep your warranty valid.
• Repair a phone that shuts down randomly or restarts in a loop.
• Restore system apps that were accidentally removed or corrupted.
• Recover from “Download DA FAIL” errors and Secure Boot authentication issues specific to the MediaTek chipset in your device.

Verify Your Infinix S4 X610B Model Before Downloading

Choosing the correct firmware file is the most important step to avoid damaging your device. Before downloading anything, verify your exact device identity:

1. Open About Phone: Your device model must read “X610B” exactly. Even small differences in the code can mean a completely different chipset and partition layout.
2. Verify the Chipset Type: This firmware targets MediaTek MT6765 Helio P35/G35 specifically. Flashing it on a different chipset will fail or could brick the device.
3. Check Your Current Firmware Version: Compare your build number with the versions listed in the download section to decide which file to use.
4. Use Recovery Mode: If you cannot access Settings (phone is stuck or locked), boot into recovery mode to read the build and chipset details from the screen.
5. Regional Compatibility: Some Infinix firmware packages target specific regions. Confirm the download matches your device origin.

Which Firmware Version Should I Download?

Use the table below to determine which specific firmware version you should download for your situation:

Your Situation	What I Recommend
Phone is completely dead or stuck on logo	V304, download this one. It is the latest Infinix S4 X610B 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 V304 first, then follow the IMEI repair guide. Do not skip the reflash.
V304 failed with a flash error	Try the next older version instead and double-check your scatter file selection before assuming the firmware is the problem.
Restoring to factory / warranty repair	V304, clean state, fresh start.

My general approach with MTK devices: always try the latest version first. I have seen people spend a lot of time trying older builds when the newest one would have worked fine. Only move to an older version if the latest fails more than once, and make sure it is a driver issue you are solving, not a firmware issue.

Prerequisites for Infinix S4 X610B Firmware

Do not skip this section. Most failed Infinix flashes come from rushing through the preparation steps. The VCOM driver installation is essential for the Infinix S4 X610B and other MediaTek devices. Windows may show the device in Device Manager and SP Flash Tool will still not detect it if the correct VCOM driver is not installed.

1. Back Up IMEI Numbers: Dial *#06# and write down both IMEI numbers now. You will need these if you need to restore your IMEI after flashing.
2. Remove Google Accounts: Sign out of all Google accounts to prevent FRP lock after flashing.
3. Back Up Your Data: Back up everything, photos, contacts, WhatsApp chats, important files. Flashing wipes the device completely.
4. Charge Your Device: At least 50% battery. A device that powers off during a flash is very difficult to recover.
5. USB Cable & PC: Use a proper data USB cable, not a charge-only cable, and a Windows computer with available USB ports.
6. Install Required Drivers:
   • VCOM Drivers
   • Infinix USB Drivers

Step-by-Step: Flash Infinix S4 X610B Stock ROM

We are using SP Flash Tool for this. For older devices, I recommend trying SP Flash Tool v5.1924 first. The newer versions of SP Flash Tool require a DA (Download Agent) file that older firmware packages do not include, and that is what causes the “Auth” errors you may have seen. If SP Flash Tool keeps asking for an auth file and you do not have one, switch to MTK Client, it handles Secure Boot automatically. Download SP Flash Tool for Windows or SP Flash Tool for Linux and follow the steps below. The complete SP Flash Tool guide is also available if you need more detail.

1. Download and Unpack:
   • Pick the correct firmware version from the downloads above and save it to your PC.
   • Extract the ZIP file. If the extracted folder contains another ZIP inside, extract that one too. You should end up with the actual firmware files, not another archive.
2. Driver Check:
   • Double-check that you have installed the required drivers. A missing driver is the most common reason the flash tool cannot detect your phone. Reboot your PC after installing.
3. Load the Firmware File:
   • Click on the “Scatter-loading” button. Navigate to the folder where you extracted the firmware and select the “scatter.txt” file.
4. 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.
5. Start Flashing:
   • Start the flash by clicking “Download”.
   • Leave everything untouched until completion. Even bumping the USB cable can interrupt the write and cause a failed flash.
6. Wait and Reboot:
   • The flash is complete when the tool shows a success indicator. Disconnect your phone.
   • Turn the phone on. Do not worry if it sits on the boot logo for several minutes, the system is rebuilding itself from scratch.

What to Expect After Flashing

After a successful flash, you will notice a few changes and behaviors:

• How to know the flash was successful: SP Flash Tool will show a green circle or checkmark when done. If you see that, the flash completed successfully.
• 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.
• 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.
• Notification sounds and ringtones will be back to factory defaults. Any custom tones you had set before will need to be re-downloaded and re-assigned in 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.
• 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.
• 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.

What to Do if Infinix S4 X610B Flash Fails

1. Infinix S4 X610B Not Recognized by SP Flash Tool:
   • In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the X610B, restart your PC, and try again before changing anything else.
   • If that does not work, switch to a USB 2.0 port, USB 3.0 ports can cause detection issues with MediaTek devices more often than people expect.
   • Still not working? Temporarily disable your antivirus. It can block the VCOM driver from loading without giving you any error message.
2. Boot Loop After Flashing:
   • Enter recovery mode and perform a factory reset from there. Most post-flash bootloops on MediaTek are caused by conflicts with old cached data, a wipe from recovery usually fixes this without needing to reflash.
3. Wrong Scatter File / Firmware Mismatch:
   • If SP Flash Tool throws an error as soon as you try to start the download, check your scatter file first. A mismatch between the scatter file and your device build is one of the most common causes of flash errors.
4. “Download DA FAIL” Error:
   • This error comes up regularly. It almost always means the VCOM driver is not properly installed. Reinstall it, restart your PC, and try again. If that still does not work, try switching to SP Flash Tool v5.1924, older devices sometimes respond better to the older version.
5. Error 8038 (BROM Error):
   • The device is not entering BROM mode correctly. Power it off completely and, if possible, remove the battery for 30 seconds. Reconnect and try again. Some MediaTek devices require you to hold Volume Down while plugging in the USB cable to enter BROM mode.
6. Auth File / Secure Boot Error in Newer SP Flash Tool:
   • Newer versions of SP Flash Tool require a DA (Download Agent) authentication file for devices with Secure Boot enabled. If you do not have that file, switch to MTK Client instead, it handles Secure Boot automatically and is the simpler solution.

Missing IMEI or Corrupt Baseband on Infinix S4 X610B After Flashing?

A missing or unknown IMEI is one of the most common things I see after a MediaTek flash. It happens because the NVRAM partition, which stores your IMEI and calibration data, sometimes does not survive the flash intact. It looks alarming, but it is fixable. Here is what to do:

1. Check your drivers first: Install the Mediatek CDC Driver if you have not already, without it, the IMEI repair tools will not detect your device. This is the step most people miss.
2. Use SN Write Tool or Maui Meta: SN Write Tool is the first option I try, it is straightforward and works on most MTK devices. Maui Meta is the alternative if SN Write does not connect. You can learn more about using SN Write Tool here.
3. Run the repair:
   • Connect your device to the computer.
   • Enter the original IMEI numbers for both SIM slots, these are the numbers you wrote down before flashing.
   • Click “Start” and let it complete without interrupting the connection.
4. Verify after reboot: Once done, reboot your phone and dial *#06#. Your IMEI numbers should be back. If they are still showing null, run the process again, sometimes the first attempt does not complete correctly.

Questions About Infinix S4 X610B Firmware

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: Is this firmware compatible with other Infinix models?
A: No. This firmware is built specifically for the Infinix S4 X610B running on the MediaTek MT6765 Helio P35/G35 chipset. Even variants of the S4 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.

Q3: My device is not detected by SP Flash Tool. What should I do?
A: Start with the drivers, reinstall the VCOM 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 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.

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: 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 MediaTek devices, SN Write Tool or Maui Meta will handle the repair. Do not insert a SIM card until the IMEI is restored.

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: Can I go back to an older firmware version?
A: It is technically possible on some MediaTek 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.
