How to Update Galaxy S3 GT I9300 with ICS 4.0.4 Parandroid Custom ROM Firmware

Galaxy S3 Green LogoSamsung 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. In the process of this article, we will be coming out on how this firmware looks like with the help of the screen captures and also the essential pre requisites to be followed and then the detailed guide in the next page. Don’t apply this update on any other smartphone apart from the I9300 variant. You can find the model number below the battery. For applying this update, the device will have to be rooted and once the device is rooted, the warranty will get void. The only way with which the warranty can be reclaimed is by re applying the Galaxy S III with the Official firmware.
