Infinix Smart3 Plus X627V Firmware (Flash File) Drivers, Tools & Guide
This guide provides the official firmware and instructions to restore your Infinix Smart3 Plus X627V. I handle Infinix Smart3 Plus X627V repairs regularly, and most of these devices arrive with FRP locks, bootloops, or issues stuck on the logo. This page consolidates the firmware, the tools, and the exact process I use to fix them.
One specific tip I always share: extract the firmware to a simple folder path, such as C:FirmwareX627V. SP Flash Tool can sometimes struggle to locate the scatter file if the folder path contains spaces or special characters. It is a small detail, but it prevents a frustrating few minutes of troubleshooting.
The Infinix Smart3 Plus X627V runs on the MediaTek MT6761 Helio A22 chipset, which means you will need SP Flash Tool and MTK drivers for the process. I have listed 15 firmware builds here, covering various Android versions and security patch levels. If one version does not work, try another. Since the device was released in 2019, Windows 10 and 11 may require manual driver installation rather than plug-and-play.
I have verified the integrity of these firmware files across three independent sources to confirm they are authentic, unmodified stock ROMs. With 15 firmware versions archived for the Infinix Smart3 Plus X627V, this page covers multiple Android builds and security patch levels.
Your Infinix Smart3 Plus X627V 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.
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.
Remove FRP Lock on Infinix Smart3 Plus X627V
The quickest method to bypass the Google lock on your Infinix Smart3 Plus X627V involves using a compatible app launcher that allows access to 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.
Infinix Smart3 Plus X627V Hard Reset Guide
You can perform a hard reset on the Infinix Smart3 Plus X627V without a computer by powering off the device completely, then holding 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 Smart3 Plus X627V 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.
Infinix Smart3 Plus X627V Firmware Compatibility Check
Selecting the wrong firmware variant is the most common error, so verify your exact device details before downloading. Before downloading anything, confirm your exact model identity:

Which Firmware Version Should I Download?
Determining the correct firmware version depends on your specific problem, so refer to this decision table for guidance. 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 | V340, download this one. It is the latest Infinix Smart3 Plus X627V 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 V329, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V340 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V340 failed with a flash error | Try V329 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V340, 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 Smart3 Plus X627V (X627V) should not be confused with other Smart3 Plus variants that may have different chipsets or regional firmware. Even devices in the same Smart3 Plus line can use completely different processors. Always verify your exact model code “X627V” in Settings > About Phone before downloading any firmware from this page.
- Confirm your exact model is X627V, check About Phone, not the marketing name on the box.
- Your device must have a MediaTek MT6761 Helio A22 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.
Prepare Your Infinix Smart3 Plus X627V for Flashing
Proper preparation is essential to prevent flashing failures on the Infinix Smart3 Plus X627V. The VCOM driver installation is crucial for this MediaTek device. 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.
- 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 Smart3 Plus X627V Firmware With SP Flash Tool
The standard method for flashing the Infinix Smart3 Plus X627V is using SP Flash Tool. 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 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.
Common Issues When Flashing Infinix Smart3 Plus X627V
- Infinix Smart3 Plus X627V Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the X627V, 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.
What Is Normal After a Infinix Smart3 Plus X627V Flash?
After completing the flash on your Infinix Smart3 Plus X627V, several things are expected to occur.
- 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.
- 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 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.
- 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.
- 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.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
Missing IMEI or Corrupt Baseband on Infinix Smart3 Plus X627V After Flashing?
A missing or unknown IMEI is a frequent issue after flashing the Infinix Smart3 Plus X627V, but it is repairable. 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.
