Infinix Smart HD 2021 X612 Firmware (Flash File) Drivers, Tools & Guide
This guide covers the complete process for restoring your Infinix Smart HD 2021 X612 to a working state. I have handled many Infinix phones over the years, and the Infinix Smart HD 2021 X612 comes in often with bootloops or FRP locks. The resources below include the official stock firmware, the required drivers, and the exact steps I use to resolve these problems.
One practical tip I always share: extract the firmware to a simple folder path, such as C:FirmwareX612. SP Flash Tool can sometimes struggle to locate the scatter file if the folder path contains spaces or special characters. This small step saves a frustrating few minutes of troubleshooting.
This page lists 10 firmware builds for the Infinix Smart HD 2021 X612, covering multiple Android versions and security patch levels. If one build does not work, try a different version. The stock firmware ships with Android 10 (Go edition), XOS 6.2, which determines the default apps, security features, and interface you will see after flashing. The Infinix Smart HD 2021 X612 runs on a MediaTek MT6580 chipset, which means you will use SP Flash Tool and VCOM/MTK drivers for flashing. These are included in the prerequisites below.
The Infinix Smart HD 2021 X612 was released in 2020. This page is maintained with the latest available firmware builds as they become available. This firmware was sourced directly from verified repositories and checked for integrity before being listed on this page.
Your Infinix Smart HD 2021 X612 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.
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.
How to Wipe Infinix Smart HD 2021 X612 to Factory Settings
To factory reset Infinix Smart HD 2021 X612 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 Smart HD 2021 X612 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.
FRP Removal for Infinix Smart HD 2021 X612
The fastest way to bypass FRP on Infinix Smart HD 2021 X612 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.
When Should You Flash Infinix Smart HD 2021 X612?
The Infinix Smart HD 2021 X612 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:
- Resolve touchscreen responsiveness issues caused by a corrupted system build.
- Resolve OTA update failures and battery drain issues.
- Restore the original Infinix stock ROM to keep your warranty valid.
- Remove persistent malware or adware that survives a factory reset.
- Clear a forgotten screen lock, PIN, or pattern without needing the original credentials.
- Fix Wi-Fi, Bluetooth, or mobile data connectivity that stopped working after an update.
- Recover from “Download DA FAIL” errors and Secure Boot authentication issues specific to the MediaTek chipset in your device.

Verify Your Infinix Smart HD 2021 X612 Model Before Downloading
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 “X612”. Some Infinix phones share the same marketing name but have different internal hardware.
- Confirm the Processor: This build targets the MediaTek MT6580 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 | V048, download this one. It is the latest Infinix Smart HD 2021 X612 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 V045, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V048 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V048 failed with a flash error | Try V045 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V048, 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.

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 Smart HD 2021 X612 (X612) should not be confused with other Smart HD 2021 variants that may have different chipsets or regional firmware. Even devices in the same Smart HD 2021 line can use completely different processors. Always verify your exact model code “X612” in Settings > About Phone before downloading any firmware from this page.
- Go to Settings and verify your model is exactly X612. Phones with similar names can have completely different hardware.
- The chipset in your device should be MediaTek MT6580. If it is different, this firmware will not work.
- Always download directly from the table on this page to ensure you have the correct build.
- Check the file size after downloading, a mismatch with the listed size means a partial or corrupt download.
Prerequisites for Infinix Smart HD 2021 X612 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 Smart HD 2021 X612 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.
- Save Your IMEI Numbers: Type *#06# in the phone dialer and note down both numbers. These are your device identifiers for the cellular network. If flashing wipes them, you will need the originals to write them back.
- Disconnect Google Accounts: Before you start anything, remove all Google accounts from the phone. Settings then Accounts then tap each Google account and remove it. This avoids the FRP verification screen that appears after flashing if accounts were still linked.
- Create a Backup: Copy your data to your computer or an SD card. Flashing replaces the entire software on the phone, which means all personal data, apps, and settings will be permanently deleted.
- Charge First: Get the battery above 50% before starting. The flashing process takes a few minutes and the first boot takes several more. A power failure during either stage can leave the device in a state that requires more advanced recovery.
- Prepare Your PC Connection: You need a Windows computer and a USB cable that supports data transfer. Test the cable first by connecting the phone normally, if it shows up in File Explorer, the cable is good.
- Install the Right Drivers:
Install Stock Firmware on Infinix Smart HD 2021 X612
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.
- Download the Firmware Package:
- Use the download links in the table above to get the correct firmware file for your device.
- Extract the archive with WinRAR or 7-Zip. Use a short folder path like
D:flashto avoid issues with some tools.
- Check Drivers:
- All drivers from the prerequisites must be installed before connecting your device. Restart your computer after installing them.
- 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:
- Press “Download” to begin writing the firmware to your device.
- Do not unplug the phone, close the flash tool, or interact with the device until the process is 100% complete.
- Wait and Reboot:
- After the tool confirms the flash is complete, safely disconnect your phone.
- Press the power button to start your device. The initial boot is slow, wait up to 8 minutes before assuming there is a problem.
After Flashing: What Happens Next on Infinix Smart HD 2021 X612
Here is 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.
- 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.
- 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.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- 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.
Troubleshooting Infinix Smart HD 2021 X612 Flash Errors
- Infinix Smart HD 2021 X612 Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the X612, 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.
Missing IMEI or Corrupt Baseband on Infinix Smart HD 2021 X612 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:
- 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.

Common Questions About Flashing Infinix Smart HD 2021 X612
Q1: 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.
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: Is this firmware compatible with other Infinix models?
A: No. This firmware is built specifically for the Infinix Smart HD 2021 X612 running on the MediaTek MT6580 chipset. Even variants of the Smart HD 2021 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.
Q4: What if the flash fails halfway through?
A: Do not panic and do not disconnect the phone. Close SP Flash Tool, 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.
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: 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 SP Flash Tool 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: 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.
