Infinix Hot 6 Pro QL1661ABCDEF 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.
The Infinix Hot 6 Pro QL1661ABCDEF 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. The stock firmware ships with Android 8.0 (Oreo) with XOS 3.3 Hummingbird, which determines the default apps, security features, and interface you will see after flashing. Powered by a Qualcomm Snapdragon 425 (MSM8917) (Qualcomm) processor, the Infinix Hot 6 Pro QL1661ABCDEF requires Qualcomm Flash Image Loader (QFIL) and Qualcomm HS-USB drivers. Make sure to install the correct driver package before connecting your device.
With 6 firmware versions archived for the Infinix Hot 6 Pro QL1661ABCDEF, this page covers multiple Android builds and security patch levels. As a Transsion Holdings brand, Infinix devices share similar chipset architectures and flashing procedures across the Hot 6 Pro lineup.
Your Infinix Hot 6 Pro QL1661ABCDEF 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.
A full flash will erase everything on the device: apps, accounts, photos, and settings. That is the point, it gives you a clean slate and resolves issues like screen locks, FRP prompts, dead boot states, sluggish performance, and connectivity problems.
FRP Removal for Infinix Hot 6 Pro QL1661ABCDEF
The fastest way to bypass FRP on Infinix Hot 6 Pro QL1661ABCDEF 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.
Factory Reset Infinix Hot 6 Pro QL1661ABCDEF Without a PC
To factory reset Infinix Hot 6 Pro QL1661ABCDEF 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 6 Pro QL1661ABCDEF 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.
Which Firmware Version Does Your Infinix Hot 6 Pro QL1661ABCDEF Need?
The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:
- Find Your Model Code: Go to Settings, then About Phone. The code should be “QL1661ABCDEF”. If it is a different variant, do not use this firmware.
- Cross-Check the Chipset: The Hot 6 Pro QL1661ABCDEF uses Qualcomm Snapdragon 425 (MSM8917). If your phone shows a different chipset in recovery mode, stop and find the correct firmware for your hardware.
- Note Your Current Build: Write down the build number shown in About Phone. This helps you compare versions and decide whether to upgrade or reflash the same version.
- Boot Into Recovery: Recovery mode (Volume Up + Power while off) is the safest way to double-check your model info before committing to a flash.
- Check Download Size: After downloading, verify the file size matches the table on this page. Corrupt or partial downloads are a common cause of flash failures.
When Should You Flash Infinix Hot 6 Pro QL1661ABCDEF?
The Infinix Hot 6 Pro QL1661ABCDEF 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:
- 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.
- Clear a forgotten screen lock, PIN, or pattern without needing the original credentials.
- Remove persistent malware or adware that survives a factory reset.
- Recover your device when it only boots into recovery mode.
- Safely exit EDL (9008) mode after a failed flash attempt on your device.

| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V38, download this one. It is the latest Infinix Hot 6 Pro QL1661ABCDEF 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 V19, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V38 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V38 failed with a flash error | Try V19 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 | V38, 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.

Important: The Infinix Hot 6 Pro QL1661ABCDEF (QL1661ABCDEF) should not be confused with other Hot 6 Pro variants that may have different chipsets or regional firmware. Even devices in the same Hot 6 Pro line can use completely different processors. Always verify your exact model code “QL1661ABCDEF” in Settings > About Phone before downloading any firmware from this page.
- Confirm your exact model is QL1661ABCDEF, check About Phone, not the marketing name on the box.
- Your device must have a Qualcomm Snapdragon 425 (MSM8917) 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.
What You Need Before Flashing Infinix Hot 6 Pro QL1661ABCDEF
Get all of this sorted before you open QFIL for your Infinix Hot 6 Pro QL1661ABCDEF. 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:
Infinix Hot 6 Pro QL1661ABCDEF Firmware Installation Guide
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.
- 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:
- 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 “Download” 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.

Common Issues When Flashing Infinix Hot 6 Pro QL1661ABCDEF
- Infinix Hot 6 Pro QL1661ABCDEF 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 6 Pro QL1661ABCDEF 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 Hot 6 Pro QL1661ABCDEF 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.
- 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.
- 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.
- 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.
Missing IMEI or Corrupt Baseband on Infinix Hot 6 Pro QL1661ABCDEF 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.
Frequently Asked Questions
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: 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.
Q3: 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.
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: Is this firmware compatible with other Infinix models?
A: No. This firmware is built specifically for the Infinix Hot 6 Pro QL1661ABCDEF running on the Qualcomm Snapdragon 425 (MSM8917) chipset. Even variants of the Hot 6 Pro 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.
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: 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.
Q8: 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.
