After Samsung Galaxy Nexus, Nexus 7 Tab and Asus Transformer T300 which was recently updated with the Jellybean 4.1 update, an all-new update has arrived for Nexus S 4G. Please note that this is not an Official firmware released by Google Inc. but is a leaked port which is still in the early stages. There is no estimated time on by when there will be an official release. Over a period of this article we will be checking out on what are the features which work in this custom ROM firmware and also the pre requisites followed by the detailed guide in the next page.

The only way with which the warranty can be reclaimed is by re applying the factory firmware update which we will be coming up with very shortly.
