How to Update Nexus S 4G with JRN84D Jellybean 4.1 Firmware – Tutorial
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.
For applying this firmware, you need to ensure that your nexus S 4G device is rooted and once rooted, you need to install the custom recovery image in your device which is like Clock Work mod recovery. Also, be informed that 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 factory firmware update which we will be coming up with very shortly. It was the last time when we saw on how you can update with the leaked version of Jellybean release and this release comes just after the earlier Jellybean release which we saw just few days back.
