Infinix Hot 6X X623 Firmware (Flash File) Drivers, Tools & Guide
Qualcomm-powered devices handle flashing differently from MediaTek. QFIL is less forgiving, and selecting the wrong programmer file will stop the process right away. I put this guide together to make things straightforward: the right firmware, the correct QFIL setup, and the steps that work reliably on 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 can cost you a lot of time troubleshooting. This page lists 11 firmware builds for the Infinix Hot 6X X623, covering multiple Android versions and security patch levels. If one build does not work, try a different version. The stock firmware ships with Android 8.1 Oreo (XOS Hummingbird 3.3), which determines the default apps, security features, and interface you will see after flashing. Powered by a Qualcomm MSM8917 Snapdragon 425 (Qualcomm) processor, the Infinix Hot 6X X623 requires Qualcomm Flash Image Loader (QFIL) and Qualcomm HS-USB drivers. Make sure to install the correct driver package before connecting your device.
With 11 firmware versions archived for the Infinix Hot 6X X623, this page covers multiple Android builds and security patch levels. The Infinix Hot 6X X623 was released in 2018. This page is maintained with the latest available firmware builds as they become available.
Your Infinix Hot 6X X623 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.
Flashing replaces your current software completely and wipes all personal data. This is by design, it is what clears out FRP locks, bootloops, pattern locks, app crashes, and other software-level problems that a regular reset cannot fix.
Hard Reset Infinix Hot 6X X623
To factory reset Infinix Hot 6X X623 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 Hot 6X X623 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.
FRP Removal for Infinix Hot 6X X623
The fastest way to bypass FRP on Infinix Hot 6X X623 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.
Why Do We Need Infinix Hot 6X X623 Firmware?
The Infinix Hot 6X X623 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:
- Resolve touchscreen responsiveness issues caused by a corrupted system build.
- Unlock your device if it has been locked or disabled.
- Recover your device when it only boots into recovery mode.
- Restore the original Infinix stock ROM to keep your warranty valid.
- Clear a forgotten screen lock, PIN, or pattern without needing the original credentials.
- Update to the latest Android version supported by your phone.
- Safely exit EDL (9008) mode after a failed flash attempt on your device.

Infinix Hot 6X X623 Firmware Compatibility Check
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 “X623”. Some Infinix phones share the same marketing name but have different internal hardware.
- Confirm the Processor: This build targets the Qualcomm MSM8917 Snapdragon 425 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.

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 | V68, download this one. It is the latest Infinix Hot 6X X623 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 V38, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V68 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V68 failed with a flash error | Try V38 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 | V68, 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 Hot 6X X623 (X623) should not be confused with other Hot 6X variants that may have different chipsets or regional firmware. Even devices in the same Hot 6X line can use completely different processors. Always verify your exact model code “X623” in Settings > About Phone before downloading any firmware from this page.
- Your model number is a variant of X623 with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.
- Your chipset differs from Qualcomm MSM8917 Snapdragon 425. 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.
Infinix Hot 6X X623 Flash Setup Checklist
Get all of this sorted before you open QFIL for your Infinix Hot 6X X623. 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.
- 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:
Flashing Infinix Hot 6X X623 Firmware With QFIL (Qualcomm Flash Image Loader)
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.
Video Guide for Flashing
What Is Normal After a Infinix Hot 6X X623 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.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- 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.
- 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.
- 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.
What to Do if Infinix Hot 6X X623 Flash Fails
- Infinix Hot 6X X623 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 Hot 6X X623 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.
Missing IMEI or Corrupt Baseband on Infinix Hot 6X X623 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.
Common Questions About Flashing Infinix Hot 6X X623
Q1: Is this firmware compatible with other Infinix models?
A: No. This firmware is built specifically for the Infinix Hot 6X X623 running on the Qualcomm MSM8917 Snapdragon 425 chipset. Even variants of the Hot 6X 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.
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: 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.
Q4: Can I flash this firmware if my phone does not turn on at all?
A: Yes, in most cases. Qualcomm devices can often be detected in EDL (9008) mode even when completely dead, QFIL can flash without the phone being on. If the battery is completely drained, charge it for at least 15 minutes first.
Q5: 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.
Q6: 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 QFIL (Qualcomm Flash Image Loader) appears stuck, give it a few more minutes before assuming something went wrong.
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 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.
