Infinix Hot 12i X665B Firmware (Flash File) Drivers, Tools & Guide
The Infinix Hot 12i X665B frequently arrives in repair shops with common issues like FRP locks, bootloop problems, or getting stuck on the Infinix logo. This guide consolidates everything you need: the firmware files, essential tools, and the exact procedure I follow in practice.
Before beginning, always extract firmware to a straightforward folder path like C:FirmwareX665B. SP Flash Tool sometimes fails to locate the scatter file if the folder contains spaces or special characters. It’s a simple step that prevents frustrating minutes of troubleshooting why the tool won’t load your files.
Your Infinix Hot 12i X665B operates on a MediaTek MT6761 Helio A22 chipset, requiring SP Flash Tool and VCOM/MTK drivers for flashing. This page lists 17 firmware builds for the Infinix Hot 12i X665B, covering multiple Android versions and security patches. If one build fails, try another version. Released in 2022, the Infinix Hot 12i X665B may require manual driver installation on newer Windows systems (10/11) rather than plug-and-play functionality.
The Infinix Hot 12i X665B firmware arrives as a compressed ZIP file. Download and extract it using WinRAR or 7-Zip. After extraction, confirm the presence of the scatter file in the folder before proceeding.
Remember that flashing stock firmware completely wipes all data, this is intentional as it resolves software issues including FRP locks, app malfunctions, sluggish performance, forgotten screen locks, logo-stuck devices, Wi-Fi/Bluetooth problems, battery drain, and soft brick situations.
Bypass Google Lock on Infinix Hot 12i X665B
The quickest method to bypass FRP on Infinix Hot 12i X665B involves using a free Android apps launcher that lets you access settings during the setup wizard. After flashing or performing a factory reset, you might encounter a Google account lock (FRP). Our free Android apps launcher provides the fastest way to bypass this. This is why I always recommend removing your Google account before flashing, it completely avoids this problem.
Infinix Hot 12i X665B Hard Reset Guide
To factory reset Infinix Hot 12i X665B without a computer, power off the device completely, then simultaneously hold Volume Up and Power until the recovery menu appears. Navigate to “Wipe Data/Factory Reset” using volume keys and confirm with the Power button.
A hard reset erases all data and returns Infinix Hot 12i X665B to its original factory condition. This resolves most software problems, sluggish performance, app crashes, forgotten screen locks, and bootloops. If issues persist after factory reset, a full firmware flash using SP Flash Tool is covered in following sections.
Which Firmware Version Does Your Infinix Hot 12i X665B Need?
The most frequent mistake I observe is flashing firmware intended for a different variant. Before downloading anything, verify your exact device identity:
- Find Your Model Code: Navigate to Settings > About Phone. The code should be “X665B”. If it shows a different variant, do not use this firmware.
- Cross-Check the Chipset: The Hot 12i X665B uses MediaTek MT6761 Helio A22. If your phone displays a different chipset in recovery mode, stop and find the correct firmware for your hardware.
- Note Your Current Build: Record 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) provides 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 frequently cause flash failures.
Why Flash Stock ROM on Infinix Hot 12i X665B?
The Infinix Hot 12i X665B utilizes a MediaTek chipset, making SP Flash Tool the standard method for firmware recovery on MTK devices. Here’s how flashing stock firmware helps:
- Remove a forgotten screen lock, PIN, or pattern without requiring original credentials.
- Restore system apps accidentally removed or corrupted.
- Recover your device when it only boots into recovery mode.
- Update to the latest Android version supported by your phone.
- Eliminate persistent malware or adware surviving a factory reset.
- Restore original Infinix stock ROM to maintain warranty validity.
- Resolve “Download DA FAIL” errors and Secure Boot authentication issues specific to the MediaTek chipset in your device.

Which Firmware Version Should I Download?
This is the most frequent question I receive in comments, so I’ve created a simple guide. Find your situation in the table and go directly to the appropriate file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V991, download this version. It is the latest Infinix Hot 12i X665B 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 recent OTA update | Try V674, sometimes the latest OTA introduces new bugs and an older build performs better. |
| IMEI missing after previous flash | Re-flash V991 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V991 failed with flash error | Try V674 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V991, clean state, fresh start. |
My general approach with MTK devices: always attempt the latest version first. I have observed people spend considerable time trying older builds when the newest one would have worked perfectly. Only switch to an older version if the latest fails more than once, and confirm you are resolving a driver issue, not a firmware problem.

Only download firmware fully compatible with your exact device model. See the firmware selection guide above if you are not sure.
Important: The Infinix Hot 12i X665B (X665B) should not be confused with other Hot 12i variants that may have different chipsets or regional firmware. Even devices in the same Hot 12i line can use completely different processors. Always verify your exact model code “X665B” in Settings > About Phone before downloading any firmware from this page.
- Your model number is a variant of X665B with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.
- Your chipset differs from MediaTek MT6761 Helio A22. 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.
Prepare Your Infinix Hot 12i X665B for Flashing
Do not skip this section. Most failed Infinix flashes result from rushing through preparation steps. The VCOM driver installation is essential for the Infinix Hot 12i X665B and other MediaTek devices. Windows may display the device in Device Manager and SP Flash Tool will still not detect it if the correct VCOM driver is not installed.
- 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:
Flashing Infinix Hot 12i X665B Firmware With SP Flash Tool
We are using SP Flash Tool for this process. For older devices, I recommend trying SP Flash Tool v5.1924 first. Newer versions of SP Flash Tool require a DA (Download Agent) file that older firmware packages do not include, causing “Auth” errors you may have encountered. If SP Flash Tool repeatedly requests 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.
- 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:
- Click on the “Scatter-loading” button. Navigate to the folder where you extracted the firmware and select the “scatter.txt” 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:
- 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.
Fix Common Infinix Hot 12i X665B Firmware Errors
- Infinix Hot 12i X665B Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable problem. Reinstall the VCOM drivers for the X665B, 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.
- 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.
- 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.
- “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.
- 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.
- 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.
Post-Flash Behavior on Infinix Hot 12i X665B
Here’s what is completely normal after a successful flash:
- 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.
- 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.
- 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.
- 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.
- 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.
Missing IMEI or Corrupt Baseband on Infinix Hot 12i X665B 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’s what to do:
- 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.
- 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.
- 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.
- 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.

Infinix Hot 12i X665B Firmware FAQ
Q1: 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.
Q2: 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.
Q3: 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.
Q4: Is this firmware compatible with other Infinix models?
A: No. This firmware is built specifically for the Infinix Hot 12i X665B running on the MediaTek MT6761 Helio A22 chipset.
