If you are still using the Samsung Galaxy S3 as you daily driver, or even if you use the S3 as a backup phone, you can now test something that’s really great. Yes, I am talking about the latest Android 7.1 Nougat software which is available for your smartphone in form of a new custom ROM system. The ROM is dubbed as AICP and promises a smooth and stable Android experience for the Samsung Galaxy S3. So, if you want to learn more about this software and about the actual flashing procedure, don’t hesitate and read all the lines from this step by step guide.

In case you are wondering how the latest Android firmware can smoothly run on an outdated device, remember that we are talking about a custom ROM and not about an official software. AICP is developed by third party devs and has nothing to do with Samsung or with Google. So, the Android 7.1.0 Nougat ROM was customized and optimized especially for the Galaxy S3 in order to perfectly fit with the performance of your smartphone.

Of course, the Nougat software comes with all the latest Android features, apps and capabilities but with a modified system that isn’t the same as the stock one. Also, the UI will be also different from what you know, but that is not a bad thing – with the AICP software installed, your Samsung Galaxy S3 should run better and even faster not to mention that you are able to customize, optimize and personalize everything else by applying various other tweaking procedures.

A custom ROM is a third party release of Android but it is only based on the stock OS. Since the update has nothing to do with your OEM and since we are not talking about an official software you have to realize that this update process is not an official one. Thus, you are going to lose your phone’s warranty – that’s not going to be a real problem since the S3 was first released back in 2012.

What is more important than the warranty is your personal data. Unfortunately, if you want to update to Android 7.1.0 first you will have to make a hard reset and clear app data cache. Without wiping out the system of your Galaxy S3 you won’t be able to use the AICP firmware. So, as a precaution, make a general backup operation by syncing your data with your account or by using other similar services from Google Play or from any other source you prefer. And along with your personal files you should also make a Nandroid backup – thus, save the Android system that currently powers your handset as if the new Android Nougat platform will not be on your taste you will be able to go back to stock without problems.

A custom ROM, such as the AICP platform, can be installed only on an unlocked software and only if a custom recovery image can be used. So, in our case you first have to root your Samsung Galaxy S3 and to install CWM or TWRP recovery – the ROM file is being offered in form of a .zip package that can be installed only through a custom recovery environment.

In addition other general pre requisites must be considered before anything else – so check the lines from below and apply the tasks from there before using the AICP Nougat update on your Samsung Galaxy S3:

  • The firmware package must be downloaded on a computer or on a notebook. So, make sure you can use a computer for completing this task.
  • Your Galaxy S3 will have to be connected with the computer at some point. So, your phone and its USB cable are also required.
  • In order to properly ensure this connection, first on your phone you must enable the USB Debugging option from Developer Options.
  • Gaining developer options can be done by: going to “menu – settings – about phone” from where you have to tap 7 times repeatedly on Built Number.
  • Then, you can access the USB Debugging option by going to “menu – settings – developer options”.
  • And, as usual when talking about update operations, or about custom procedures, you have to verify the power that’s left on your Android device – as a general rule you have to plug in the charger if the battery power left is lower than 50%.
  • Do not skip the charging process. Otherwise your smartphone might get turned off while you are still trying to flash the AICP Android 7.0 Nougat firmware – if that happens your device might get bricked (various software related problems might be caused).

How to Install Android 7.1.0 Nougat Firmware on Samsung Galaxy S3

  1. Start by downloading the AICP software. You can get this Android 7.1.0 Nougat based ROM from here.
  2. Also download compatible Google Apps package – you have to flash Google Apps separately as it isn’t included in the firmware package.
  3. Save the downloaded files on desktop if that’s ok for you.
  4. Power on your Galaxy S3 and then remember to charge it if that’s required.
  5. Connect your phone with your computer – use the USB cable in that respect.
  6. Select the downloaded files on your desktop and then transfer the files from your computer to your device.
  7. Next, remove the USB cord – the computer is no longer required.
  8. Power off your smartphone – press and hold the Power key for a few moments or press the Power button once and select “power off”.
  9. After doing so, enter recovery mode on your Galaxy S3: press and hold the Power, Volume Up and Home at the same time, for a few moments.
  10. From recovery wipe everything – otherwise the new ROM can’t be installed. So, select “wipe data factory reset”, “wipe cache partition” and “wipe dalvik cache”.
  11. After clearing the internal storage system you can resume the flashing process. Thus, by using the same recovery options select “install zip from SD card” followed by “choose zip from SD card”.
  12. Pick up the Android 7.1.0 Nougat software and install the AICP custom ROM.
  13. When done, repeat the last step and install the Google Apps package on your Galaxy S3.
  14. When everything is completed go back to main menu of recovery. From there select “reboot system now”.
