Update Galaxy S I9000 with ICS Tirami Slim Custom ROM

The Samsung Galaxy S GT I9000 users are really lucky as there are many ICS updates available for their handsets. Anyway, we are talking only about custom ROMs, or beta firmware, as Samsung didn’t offered anything official yet. But if you want to get the Ice Cream Sandwich flavor on your phone, you have all the required ingredients. For proper how to guides you can search through our “update” section and then select the Galaxy S GT option; you will then be able to choose the firmware you like the most.

Anyway, that’s not all, as a new custom ROM, the Android 4.0 based Tirami Slim, has just been leaked and it’s now available for updating your I9000 smartphone. As usual, I will be teaching you in how to flash the same, all being summarized in an easy to understand and fast to complete step by step guide. I will be showing you the pre requisites, the advantages that come with a custom ROM, the negative aspects and the Tirami Slim features list, so for making a background view about this OS upgrade I recommend you to check the following lines.

First of all you must know that the Tirami Slim firmware can be applied only if you have a rooted Galaxy S GT device. Furthermore the phone should run the XXJW4 operating system. If not go and gain root access and then return here. Before you do that, remember that once you apply the mentioned operation the warranty will be void. You have nothing to worry about though as by following this tutorial your handset will be in safe hands. Just don’t try to flash the ROM by yourselves. The warranty can be restored if you choose to apply the stock ROM (implies to do a downgrade), update with an official software (you will have to wait for that), or to re-lock the bootloader.

Another aspect that you must know before starting the proper procedure is related to the data stored on your Galaxy S GT. As you will see during the steps, a full wipe of the system will be required. So, you need to save your personal info first. I recommend you to do a backup. You can read this how to guide for learning more about this method. You can backup and then restore almost anything from your smartphone: messages, call logs, internet settings, contacts, images, videos, calendar info and even the market applications.

Now, let’s talk about the Tirami Slim Custom ROM. It is based on the ICS platform, so the Android 4.0 OS will be included. As usual, the firmware was developed and tested by those of xda-developers, so we have to thanks them for this how to guide. Being a custom ROM, the Tirmai Slim, will power up the performances of your Galaxy S GT by adding numerous features that can’t be found in the default version of the software. You will be able to customize and optimize the system, gain more speed, more access to the OS (it will be unchained from the factory restrictions), have an optimized RAM memory and a lot more. A new interface will also be included with new themes and background images. A more detailed list of the features can be checked below:
