This page contains the download link for the official Infocus IN610 stock ROM (firmware) flash file that you can download onto a computer and then flash it with an appropriate flashing tool.

The Android operating system has many versions. The first version, called Android 1.0 back in 2008, has now been succeeded by one major release every year and now we’re up to Android 9.0. The iPhone also gets one major release of iOS software per year, but that’s about where the similarities end. Unlike the iPhone, just because you have a new device that runs Android doesn’t mean you will necessarily be running the latest version of Android. This is due to a number of reasons: the different hardware packed inside high-end, mid-range and low-end smartphones, these companies purposefully wanting to make the more expensive devices a more attractive option to the buyer, and so forth.

Each major release of Android will come with different features, and the overall design can change substantially, too. Many of those features might seem attractive options to you, but if your carrier or manufacturer hasn’t rolled out that version of Android for your Infocus IN610 device then there’s nothing you can unless you look into the custom software alternatives. Many developers create custom software that allows users of a particular device to update to a version of Android that wouldn’t be possible from official updates. These are known as custom ROMs. But if you didn’t want to delve into the world of custom software, there are differences between locked devices and unlocked ones too.

If your Infocus IN610 device is carrier locked, then you’ll only be able to install updates from the carrier, and that same carrier will also direct the updates you receive. On the other hand, if you have an unlocked device, then the updates are being distributed by the manufacturer instead, so the updates will be different and arrive at different times. Whats more, unlocked devices also have the added flexibility of being able to install firmware made for other carrier networks, as long as it is still the same device. There are some exceptions: for example, ZTE has some model numbers that are available for different parts of the world and because they come with different hardware, flashing the file for the wrong region can create problems. If the hardware is the same, then it’s generally not an issue. If you’re in doubt, you can always contact the manufacturer or get in touch with a support forum.

What Is Android Firmware?

Firmware is the operating system and its applications that control how the smartphone or tablet that runs on Android operates. While you may see the words “software update available” on your device’s display, we call it firmware to highlight its close relationship with the device manufacturers hardware.

If you prefer technical jargon, firmware is the specific programming that gets written to a device’s non-volatile memory. The firmware gets added to the device during the manufacturing process and is the middleman in helping software run on the hardware. Firmware can be written as read-only memory (ROM), erasable programmable read-only memory (EPROM), or flash memory.

The Android operating system is more open than much of its competitors in iOS, Windows 10 Mobile, and Tizen. You always get firmware running on your device out of the box, but if you do not like it, you can swap it over with custom firmware or other firmware versions that were made for your device. This flexibility helps with troubleshooting, or if you know you would prefer a different Android version that was made available.

Why Reinstall Stock Firmware?

Did you think you may need to restore the stock firmware on your device? Here are some of the things that you can achieve with stock firmware files:

  • Upgrade or downgrade the version of Android on your device
  • Fix common mobile device-related problems, such as unbearable bugs in the software
  • Remove custom recovery images such as TWRP
  • Unroot the Android operating system, regardless of what method/tool you may have used to get root access
  • Unbrick your smartphone or tablet
  • Reinstall the operating system
  • Fix invalid IMEI problems

How to Flash Stock ROM Using SUT L3 Tool

1. Start by downloading the Software Update Tool to your computer and then extract the file by right-clicking > selecting “Extract” from the menu. (“L3” is the version of the Software Update Tool, so make sure you download the right one from the list on the download page.)

2. Your computer may prompt you to install .net framework on the computer before the installation is complete. Follow the guidelines to get that done if it asks you for it.

3. Follow the SUT setup wizard found in the extracted folder.

4. Turn off the Android smartphone by holding in the Power button until the device turns off.

5. Source the firmware file that you’re looking to flash and then download the file onto your computer.

6. Once the firmware is extracted and ready to install, open the SUT L3 Tool and then click on the “Next” button from its main interface.

7. Click on the dots next to where it says “Please select the software image file” and then browse through your computers hard drive to the location of the firmware that you extracted earlier and upload it to this location in the flashing tool.

8. Once you’ve successfully uploaded the firmware, you’ll see the firmware extension path in the box.

9. Now click on the drop’down menu where it says “None” and select the “Enable Emergency Download Process” option from the list instead.

10. With the Android device still turned off connect it to the computer with its USB cable and then click on the “Next” button from the SUT interface.

11. You should now see a message on the flash tool’s interface letting you know that it is “loading the image files….”

12. This now means that the firmware is getting flashed to your device. Once you can see the green tick, you know that the flashing is complete and your device is ready to disconnect from the computer.

Your new stock firmware should now be installed and ready to use.

Alternative Flashing Method

[*] All firmware files for the Infocus IN610 smartphone may need to be flashed from within recovery mode instead of using the Software Update Tool. To do that, you need to transfer the files to the internal storage SD card and then boot to recovery mode for the flashing.

Important Notes

[*] Back Up Your Data: You should always back up your data before you begin flashing new firmware files to your smartphone or tablet. All of your pictures, music, videos, documents, etc. should be still on your device after you have updated the firmware, but you may need to restore the contacts and applications from a backup.

[*] Wipe Cache and Factory Reset: Some people claim that taking a factory reset isn’t necessary after updates, but at the very least you should wipe the system cache after installing new firmware. This way you can help eliminate any performance issues and battery draining bugs. Taking a factory reset is the best way of avoiding common problems many users face after applying software updates.


There are some common questions people have before installing firmware files. Here are the ones we are regularly asked:

How to Unroot When Installing New Firmware

There can often be a variety of ways to unroot a device that runs Android, and they depend on what method you used to get root access. If you installed SuperSU for root access, then you can open the app and find the option to unroot directly from SuperSU’s settings. On the other hand, if you do not have SuperSU, and you do have a Infocus smartphone or tablet, then you can always unroot by installing the stock firmware. Once you have followed the guide above, your device will automatically be unrooted. You can verify that is the case by installing one of the many applications from Google Play that checks for root access. As long as you are using a reliable app, then typically it will not lie about the root status of your mobile device.

How to Restore Stock Recovery on When Installing New Firmware

One of the most common reasons for installing the stock firmware is to remove a custom recovery image and revert to the stock recovery. There is nothing you need to do extra to reinstall the stock recovery on your device; when you install the stock firmware, it will automatically install the stock recovery partition on the device once again.

Additional Firmware

You can download Android firmware for other Android devices if you have another smartphone or tablet from a different manufacturer.
