How to Update Galaxy S3 GT I9300 with ICS 4.0.4 Parandroid Custom ROM Firmware
Samsung Galaxy S3 GT I9300 smartphone users can now make use of the parandroid Custom ROM firmware which we earlier saw on how you can install on the Galaxy Nexus smartphone. This Parandroid custom ROM firmware comes along with a host of add on applications which are not just productive but also comes along with the redefined ICS experience which still we feel Samsung lacks at it when compared to the Pure ICS experience which is on the Galaxy Nexus. Please note that this is not an Official firmware released by Samsung and is a custom ROM firmware developed by the Parandroid team.
Very soon there will be an early release of Jellybean 4.1 release and other custom ROM firmwares which too we will see in the coming days.
