Jelly Bean update
XXDLI3 Android 4.1.1 firmware is available for Galaxy S3.

Official Jelly Bean firmware for the international version of the Samsung Galaxy S3 (i9300) has been leaked, as the file was being rolled out to Kies servers. The leaked file is XXDLI3 Android 4.1.1. This latest leak, Team Android claims, transfers successfully to the S3 and almost all features have been reported as working properly. An earlier build, XXDLI2, SamMobile indicates, was the most stable to date, and included enhanced menu options, increased RAM and improvements to the TouchWiz User Interface (UI) and Wi-Fi connectivity options. 

Users looking to update the Galaxy S3 with the XXDLI3 firmware may follow the instructions below. IBTimes UK warns its readers it will not be held responsible for damage to the device during installation.

Users are advised to download USB drivers and enable USB debugging mode. Also ensure the phone is factory unlocked and the battery is properly charged. Do not forget to back-up important data before proceeding and verify the build number of the Galaxy S3, since this firmware works only with the international version.
