In this tutorial, we will present you with the steps you need to take in order to perform this update on your Galaxy S3. However, before getting to the actual steps, we suggest you to read the following preparation guidelines, and follow the recommendations literally.

  • The info in this post is only for Samsung Galaxy S3 I9300. By default, you should not try to use this tutorial for any other device, as you may permanently damage it. Check and verify if you own the right model by going to “Settings” > “About Phone”.
  • Your device must be rooted, unlocked from any particular carrier and it should run a custom Recovery image such as CWM or TWRP.
    - the easiest method to root and install CWM Recovery image on your Galaxy S3 handset can be found here.
  • At a certain point during the procedure you will be required to apply a reset of your S3 to the factory settings. This will result in a loss of the data and files existent on the system partition, but it won’t affect the data and info on the device’s SD card. If you want to not loose data or files that you consider important, then create a backup of your phone’s content, by using a free backup tool such as “Titanium Pro” or “Helium”.
  • Make sure you have available a proper USB cable to connect your phone to the PC, and also you must download and install the proper Samsung USB drivers on your computer.
  • Go to the “Developer Options” section and enable the “USB Debugging” option.
  • Disable any antivirus soft, in order to prevent any installation interruptions.
  • Although not mandatory, we recommend you to create a Nandroid Backup for the firmware that’s currently running on your phone, so that a restore point will be created and can be accessed in case of any installation failure.
    - the procedure will be explained later in this post.
  • Last, make sure the battery level of your S3 is over 50%, as you want to prevent any unexpected shut downs due to the lack of power.

If you read the guidelines and you followed the recommendations, then you’re ready to continue the tutorial.
