Now, before heading to the proper steps from below, you need to prepare your phone for the installation procedure that will follow. Also, you need to check some extra info for ensuring that you are doing everything as it should. For being able to do so, first of all take a look and apply when needed the pre requisites from below.

  • This tutorial is compatible with both rooted and unrooted Samsung Galaxy S3; you will flash an official update so it doesn’t matter if your phone is currently rooted or not.
  • In case your device is rooted, after completing this guide, the root access will be revoked – you can try to root the new XWUGML4 system by using our dedicated one-click root procedure.
  • Because of that this tutorial can be used for restoring the warranty on your Android device as usually the warranty gets void once root access is gained.
  • Also, this guide should be applied if you want to replace the current ROM that is running on your Galaxy S3 with a stock and stable one.
  • You need to backup the S3 data before going any further. It is unlikely to lose your data by using this guide, but in some cases your info might get corrupted. So the best will be to use suitable backup and restore apps from Google Play in order to save everything that means something to you (including EFS folder).
  • Then, for this tutorial a computer, your phone and its USB cable will be required.
  • The computer must be based on windows as Odin (this is the program that will be used) can be installed only on the same.
  • Also, on both computer and handset it is recommended to deactivate (temporarily only) the security protection.
  • Furthermore, on your phone from path “menu – settings – developer options” enable the USB debugging option.
  • If your S3 has less than 50% power left, you will have to plug in the charger first; you can brick your phone if it gets turned off in the middle of the update process.
  • This procedure is compatible only with the Samsung Galaxy S3 model number I9300 since the Android 4.3 Jelly Bean XWUGML4 firmware has been OTA released only for the mentioned device.
