Samsung has pushed a new Nougat update for all the Samsung Galaxy A3 2016 European users. This new update contains a fix for the charging bug that was affecting the previous firmware.

The new Android 7.0 build date is set for 28 September 2017, and the Security Patch level is August 2017. If you are running a newer firmware than this one, then you can ignore this post, as no charging bug is affecting your device.

The Galaxy A3 2016 charging bug doesn’t allow devices to charge to their maximum capacity, as there are numerous users reporting that their devices aren’t charging over 87%. However, the new A310FXXU3CQI8  Android 7.0 Nougat firmware update will fix this glitch and you will be able to charge your phone to 100% once again.

Before starting the flashing process you need to check the guidelines below:

  • use this tutorial only for the 2016 Samsung Galaxy A3 devices.
    – the model of your device has to be the SM – A310F.
    – don’t use the tutorial for any other different smartphones.
  • download and install the Samsung USB drivers on your PC, get them from here.
    – when installation is done you will be able to connect your phone to PC via ODIN app.
  • for the update you will use the ODIN 3.12.3 tool, and for ODIN to work with your device you will need to install the above usb drivers, and to enable USB Debugging from Developer Options menu.
  • if you cannot find Developer Options, then you will have to enable this first: go to Settings> About Phone> Software Info and tap seven times on the Firmware Build Number text to enable them.
    – the Developer Options will now be listed under Settings, open them and find USB Debugging to enable them.
  • you can flash this new update over rooted firmware, too, but you have to know that root access won’t survive the new update process.
    – any custom Recovery you might have flashed will also be replaced with stock Recovery.
  • you can flash the Android 7.0 firmware update over custom ROMs, but you have to know that a Factory Reset process has to be applied after that, too.
    – the Factory Reset process steps are listed at the end of the tutorial.
    – factory reset will wipe clean system partition, it removes the old custom ROM and it will allow the Galaxy A3 2016 to boot in normal mode.
    – no data will be deleted from Developer Options menu.
  • this guide is destined to be used by advanced users only.
  • if your phone runs 100% stock Android firmware, then you can continue to the next part of the process right away, as no data will be lost from the device during installation.
  • don’t blame us in case you brick the phone nor in case you lose any sensible data files.
  • read the whole post and don’t skip any steps.
  • also, make sure that there is at least 50% charge left before the device powers off.

These were all the guidelines you had to go over before starting the flashing process.

If you don’t wish to update your phone manually, then you can choose to wait until Samsung pushes the new firmware in your region.

You can look for new firmware updates by going to Settings> Software Update> Download Updates Manually menu. If a new firmware is ready to download, then you can simply confirm the process and your device will take care of the rest of the update process.

How to install Android 7.0 Charging BUG Patch Update for 2016 Galaxy A3 A310F:

  1. Download the Android 7.0 A310FXXU3CQI8 archive update from here.
  2. When the download is done you have to extract the archived contents.
    You will obtain five different ‘tar.md5’ update files. Don’t extract the ‘tar.md5’ archives.
  3. Download the Odin 3.12 zip from here.
    Extract the contents.
  4. Power off the phone.
  5. Launch ODIN exe on your PC.
  6. Boot it in Download Mode.
  7. Connect the Galaxy A3 2016 device to PC via usb cable.
    Wait for ODIN to add the phone, then get to the next step.
    – if the device is not added you will need to reinstall the usb drivers once again.
  8. In ODIN to need to load the firmware update files. Do it by following the info below:
    Go to the folder where you’ve extracted the firmware files at step 2. Get back to ODIN:
    Click AP and then find the file containing “AP” in its name.
    Click CP and load the file with “CP” in its name.
    Click BL and load the file containing “BL” in its filename.
    Next, click the CSC button and find and load the file with “HOME_CSC” in its name. Don’t load the file that contains only “CSC” and no “HOME” in its name, as that file will wipe clean the device storage.
  9. After you’ve loaded all the above files you will need to press START in order to initiate the Android 7 Nougat official update.
    Don’t press any buttons until the update is done.
    When installation is done you will see the PASS alert.
  10. Unplug the Galaxy A3 2016 from PC when the update is done.
    Use your default login info in order to regain control over your device once again.

I hope that you’ve managed to complete the Android 7.0 patch update for your phone.

If the ODIN app shows the FAIL alert, then you will be forced to repeat the whole tutorial more than once. Make sure that in case you repeat installation, then you will have to make sure that you won’t skip any steps and that your phone meets all requirements listed above the tutorial.


If the PASS alert is shown by ODIN, but your smartphone enters in a boot loop, or it gets stuck at the boot animation screen, then you will need to factory reset the smartphone.

The Factory Reset process wipes clean the system partition, and that’s why the info below should be applied by those that have installed the Android 7.0 Update over a custom ROM, too.

Here’s how to factory reset the device from Recovery Mode:
