You can now start updating your Galaxy Nexus to Android 4.0 Ice Cream Sandwich by installing the UltimateMIUI custom ROM into the phone’s system. The firmware was developed and also tested on a Nexus by the xda-developers member iceandfire, and it worked perfectly. So, if you want to do the same just keep reading and follow this step by step guide.

A custom ROM, like the present MIUI, is coming to spice things up by improving and powering up the performances of you smartphone. The software is including features and capabilities that can’t be found in the default version of the Android OS; that’s why the system will be optimized and customized so it can provide more speed and better performances. Also, the battery life should be improved along with the looks as a new interface will be added.

Take note that a custom ROM is not developed by Samsung and it’s not an official firmware released by the already mentioned company. This leads to a big disadvantage: once you flash MIUI, the Galaxy Nexus warranty will be void. You can regain the lost warranty by locking the bootloader and then reverting to the previously version of the Android OS.

Now, we are dealing with the 4th version of the MIUI ROM, which is based on the ICS software. So, by flashing the same, you will be able to install and enjoy the Android 4.0 OS on your own Galaxy Nexus. Remember that this tutorial is suitable and can be applied only for a Galaxy Nexus device; don’t use it to update other similar phones because you will damage or wreck its internal system.

In order to do things as it should you must first backup the data stored on your handset. Most likely, during the installation procedure your personal data, apps, messages or even contacts might be erased. You can make this save in different ways (by using a computer and a SD card) but for a full backup you can follow our previous guides (just click on the links from the list):

You should now check the enhancements that are included in the UltimateMIUI. I have listed them in the image from below, so take a look:

Now, let’s begin the proper how to guide. First make sure that you have a rooted Galaxy Nexus; ClockworkMod Recovery should also be pre-installed.

Finally, you must download the ROM to your computer; the download links are below:
