How to Update Galaxy S GT I9000 with Galaxy Nexus based ICS 4.0.4 Custom ROM

We all know that there are many high end Android powered smartphones that hasn’t receive the official Ice Cream Sandwich update yet, though many promises has been made. The same can be applied for the Samsung Galaxy S GT I9000 users who are waiting for an OS update from a while, but with no response from Samsung so far. So, the only way for improving the phone’s system will be in flashing a custom ROM, or a beta firmware. There are numerous unofficial upgrades available for the Galaxy S, but we all know that when it comes to custom ROMs it is never too much.

That’s why, today I will show you how to get and install an interesting firmware, which is being based on the Galaxy Nexus ROM (named IMM76I), meaning that the ICS OS will be also included. Therefore, if you own a Galaxy S GT I9000 device you can now flash the Nexus firmware, along with other features that are not included in the default version of the software, right into its system. In this way, you will be able to update the old Gingerbread to a more powerful platform and also make some improvements to your phone’s performances.

You can power up the speeds, optimize the battery life, customize the virtual memory, play with the looks as a new theme manager will be added along with other stuffs like wallpapers, widgets, and so on. In the same time, the system will be unlocked, so no more factory restrictions for your Galaxy S. The OS will be opened for changes, any user being able to customize and optimize it. But for more aspects check the image from below where I have listed the main aspects and features which will be added once you update your S GT I9000.

This software was developed by the xda-developers member f4K, so we have him to thanks for the same. Don’t worry, the ROM was tested before and it worked perfectly, though some minor bugs might be present. Anyway, the issues will be removed as soon as a new firmware will be made available (we will update you with the same). Now, you have to take notice in other aspects that are more important than the already up mentioned info.

The first to start with, is related to the warranty. Being a custom ROM, by flashing the Galaxy Nexus based ICS 4.0.4 firmware on your Galaxy S GT you will lose the Samsung warranty. This is happening each time you decide to install a beta update on your phone, so it’s not something exclusively. The warranty will be restored as soon as you apply an official release of the Android platform, or if you perform a downgrade operation (to the stock ROM). But for avoiding unpleasant situations I recommend you to backup the current firmware first.

Furthermore, it will be necessary to backup all the data from your Galaxy handset as during the below tutorial you will have to make a full wipe of the system. Else, the update will not be installed properly. So, just search for suitable guides through our previous posts and see how you can complete a safe and full backup. You can save messages, images, videos, apps, contacts, calendar info, internet settings and more, so don’t worry, you will not lose important info.

Then, charge your phone as the operation will take a while; your device might get turned off and we don’t want that to happen. At least make sure that there is more than 60% battery power left before starting the steps. Also, for being able to connect the handset with the computer you need to enable the USB debugging option. For doing this you must go to “Settings > Applications > Development > USB debugging” and check the last option. Last, deactivate the security programs that runs on both computer and smartphone. These were the pre requisites. You can now safely go and explore the proper step by step guide.
