The latest Android 5.1 Lollipop is now available for Samsung Galaxy S3 I9300 with the help of Omni ROM. Samsung has already discontinued the support for Galaxy S3 but those who want to update their device to the latest Lollipop can use this ROM. OmniROM is the most popular custom ROM for Galaxy S3 and if you are a Galaxy S3 user then you’ll love to test it out on your Android device.

Before proceeding, let me remind to all our readers that this ROM is not officially released by Samsung. It’s a custom ROM created by third party developers.

Prerequisites:

  • Before proceeding, make sure you have properly taken the backup of your important data including personal photos and videos.
  • Your device should have more than 60 percent battery to prevent any unexpected shutdowns during the process.
  • You have installed the Samsung Galaxy S3 USB drivers on your PC.
  • Your device must be rooted and have Custom Recovery like CWM installed.
  • You should have enabled the USB debugging mode. If you not then go to settings > Developer Options and enable it.
  • This guide is only for Samsung Galaxy S3 I9300. Don’t try it on other variants.
