Install Rooted Android 2.3.5 (GRJ90) Firmware On Nexus S 4G

Nexus S 4G 2.3.5 RootWith the Android 2.3.5 update for the Nexus S 4G up for download on the internet on the servers at Google, users must be flocking onto the download link to get their hands on the update. Considering the update is an official one, it is obvious that you will loose all root access if your device was previously rooted. Chances are, that only users who prefer stock non rooted devices, or users who don’t know much about rooting will get the official update installed on their devices, while more advanced users who prefer a rooted Nexus S 4G, will wait out for a rooted firmware or a rooting method for the 2.3.5 firmware. RootzWiki forum member Pete has just released a rooted, but completely stock Android 2.3.5 ROM for the Nexus S 4G. This was fast for sure.

There is nothing much to say about the ROM as it’s a completely stock Android 2.3.5 firmware but rooted. It contains the 4G fixes, tweaks, and full support for the smartphone’s secure NFC transceiver. Can’t wait to get this up and running on your device? Here’s how you can do that.
