Infinix S3X X622 Firmware (Flash File) Drivers, Tools & Guide
Qualcomm-powered devices handle flashing differently from MediaTek. QFIL is less forgiving, and selecting the wrong programmer file stops the process immediately. I created this guide to make the process straightforward: the correct firmware, the right QFIL setup, and reliable steps for Infinix Qualcomm devices.
The most important thing to check before you begin: after extracting the firmware, look for the Firehose .mbn file first. If it is not there, you have the wrong package. Do not load it into QFIL hoping it will work, that mistake alone costs a lot of time.
The Infinix S3X X622 was originally released in 2018, which means USB driver compatibility on newer Windows versions (10/11) may require manual installation rather than plug-and-play. Powered by a Qualcomm MSM8937 Snapdragon 430 (Qualcomm) processor, the Infinix S3X X622 requires Qualcomm Flash Image Loader (QFIL) and Qualcomm HS-USB drivers. Make sure to install the correct driver package before connecting your device. This page lists 19 firmware builds for the Infinix S3X X622, covering multiple Android versions and security patch levels. If one build does not work, try a different version.
With 19 firmware versions archived for the Infinix S3X X622, this page covers multiple Android builds and security patch levels. The Infinix S3X X622 was released in 2018. This page is maintained with the latest available firmware builds as they become available.
Your Infinix S3X X622 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 Firehose programmer file (*.mbn), rawprogram0.xml, and patch0.xml before proceeding.
Be aware that flashing overwrites the entire software partition. Your data, apps, and accounts will all be removed. This full wipe is how the flash resolves deep software issues, anything from FRP locks and boot failures to Wi-Fi problems and app crashes.
Infinix S3X X622 Google Account Bypass After Reset
The fastest way to bypass FRP on Infinix S3X X622 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.
Hard Reset Infinix S3X X622
To factory reset Infinix S3X X622 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 S3X X622 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 QFIL (Qualcomm Flash Image Loader) is covered in the following sections.
Choosing the Right Firmware Version
The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:
- Verify Your Exact Model: In Settings, look for the model code “X622”. Some Infinix phones share the same marketing name but have different internal hardware.
- Confirm the Processor: This build targets the Qualcomm MSM8937 Snapdragon 430 chipset. You can check your chipset via recovery mode or a hardware info app.
- Review the Version Number: The firmware version in the download table should be close to or newer than what your device is currently running.
- Use Recovery Mode as a Safety Check: Before flashing, boot into recovery to see the current build number and chipset printed on screen. This is the most trustworthy check.
- Verify the Region: Some firmware builds are region-specific. Confirm the download matches your device region or is listed as global.
Why Do We Need Infinix S3X X622 Firmware?
The Infinix S3X X622 is powered by a Qualcomm chipset, and when Qualcomm devices run into software problems, flashing via QFIL is the standard recovery method. Here is what the stock firmware can do:
- Unlock your device if it has been locked or disabled.
- Update to the latest Android version supported by your phone.
- Recover your device when it only boots into recovery mode.
- Resolve OTA update failures and battery drain issues.
- Clear a forgotten screen lock, PIN, or pattern without needing the original credentials.
- Remove persistent malware or adware that survives a factory reset.
- Safely exit EDL (9008) mode after a failed flash attempt on your device.

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 | V80, download this one. It is the latest Infinix S3X X622 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 V79, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V80 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V80 failed with a flash error | Try V79 instead and double-check your Firehose programmer file (*.mbn), rawprogram0.xml, and patch0.xml selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V80, clean state, fresh start. |
For Qualcomm devices, use the latest build unless you have a specific reason not to. Older Firehose packages can sometimes cause partition table issues that are difficult to fix. The newest build is almost always the right choice.

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 Infinix S3X X622 (X622) should not be confused with other S3X variants that may have different chipsets or regional firmware. Even devices in the same S3X line can use completely different processors. Always verify your exact model code “X622” in Settings > About Phone before downloading any firmware from this page.
- Confirm your exact model is X622, check About Phone, not the marketing name on the box.
- Your device must have a Qualcomm MSM8937 Snapdragon 430 chipset. Boot into recovery mode to verify if unsure.
- Only use files downloaded from this page. Third-party mirrors may serve modified or incomplete packages.
- Compare the file size against the download table. If it does not match, the download is likely corrupt or incomplete.
Infinix S3X X622 Flash Setup Checklist
Get all of this sorted before you open QFIL for your Infinix S3X X622. In most cases I have seen with Infinix Qualcomm devices, the 9008 driver installation is where things go wrong first. If Windows does not recognise your device in EDL mode, that is almost always the reason. Install the Qualcomm HS-USB driver first, restart your PC, then proceed.
- 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:
How to Install Firmware on Infinix S3X X622
We are using QFIL from the QPST suite. Make sure your device is in EDL mode, also called 9008 mode, before connecting it. The most reliable way to confirm this is to check Device Manager for “Qualcomm HS-USB QDLoader 9008.” If you see that entry, your device is in the correct mode and you can proceed.
- Download and Extract:
- Download the correct firmware package from the links above.
- Extract the ZIP to a simple folder path, avoid paths with spaces or special characters, as some flash tools have trouble with them.
- Install the Listed Drivers:
- Confirm all drivers listed above are installed and that your PC has been restarted since installation. Skipping the restart is a common reason drivers do not work correctly.
- Load the Firmware File:
- In QFIL, select Flat Build from the “Select Build” dropdown. Click Browse next to “Programmer Path” and select the Firehose .mbn file. Click Load XML and select rawprogram0.xml, then patch0.xml.
- 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 the “Download” button to begin.
- Do not disconnect, move the cable, or touch the device until the process is fully complete. Disconnecting mid-flash is how devices get bricked.
- Wait and Reboot:
- Once flashing finishes successfully, disconnect the device.
- Power on your device. The first boot will take longer than usual, give it up to 8 minutes.

What to Do if Infinix S3X X622 Flash Fails
- Infinix S3X X622 Not Entering EDL (9008) Mode:
- Hold Volume Down and Power until the screen goes black, then connect the USB cable. Check Device Manager for “Qualcomm HS-USB QDLoader 9008”, that entry confirms EDL mode is active.
- If it is not showing, the EDL test point method may be needed for your specific device. XDA Developers has guides for most models.
- QFIL “Sahara Communication Failure” Error:
- This almost always means the wrong Firehose programmer file (.mbn) was selected. Go back to the firmware folder and confirm you are selecting the .mbn file specifically.
- Boot Loop After Flashing:
- Enter recovery mode and perform a factory reset. If the recovery partition was also overwritten and is not accessible, you will need to reflash.
- Infinix S3X X622 Not Recognized by QFIL:
- Reinstall the Qualcomm HS-USB QDLoader 9008 driver and restart your PC before retrying. Antivirus software can also interfere here, disable it temporarily during the flash process.
What Is Normal After a Infinix S3X X622 Flash?
Here is what is completely normal after a successful flash:
- How to know the flash was successful: QFIL will display “Download Succeed” in the status bar. If you see this, the flash completed correctly.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Missing IMEI or Corrupt Baseband on Infinix S3X X622 After Flashing?
A missing IMEI on a Qualcomm device after flashing is less common than on MediaTek, but it does happen, usually when the modem partition was not written correctly or was left out of the flash. QFIL or QPST can be used to address this. XDA Developers has device-specific IMEI repair threads for most Infinix Qualcomm models. Look up your exact model there, the process varies enough between devices that a general guide would not give you accurate steps.
Infinix S3X X622 Flashing FAQ
Q1: 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 Qualcomm devices, QPST can handle IMEI restoration. Do not insert a SIM card until the IMEI is restored.
Q2: Is this firmware compatible with other Infinix models?
A: No. This firmware is built specifically for the Infinix S3X X622 running on the Qualcomm MSM8937 Snapdragon 430 chipset. Even variants of the S3X 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: Will flashing erase my data?
A: Yes, flashing with QFIL (Qualcomm Flash Image Loader) restores the device to factory state, including Android 8.1 Oreo (XOS Hummingbird 3.3 Lite) 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.
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 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.
Q6: My device is not detected by QFIL (Qualcomm Flash Image Loader). What should I do?
A: Start with the drivers, reinstall the Qualcomm HS-USB QDLoader 9008 driver, 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.
Q7: 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.
Q8: What if the flash fails halfway through?
A: Do not panic and do not disconnect the phone. Close QFIL (Qualcomm Flash Image Loader), 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.
