Every user of Nexus S 4G should cheer as an official Android 4.0.4 ICS ROM installation for their device has been leaked on the Internet and this means that there shouldn’t be long until the final version for ICS will be available for their devices. This post contains instructions on how to download and install the Android 4.0.4 ICS on the Nexus S 4G.

It can be easily installed on your smartphone, but still you should that the OTA update via Sprint won’t take long until it will make an appearance. However, those of you that aren’t ready to wait for that announcement to take place can download the latest Android 4.0.4 ICS Update and it has been reported that it works fine without major problems, but still there are some tweaks and changes to be made on the final release.

Before starting the installation you should make sure that your Nexus S 4G has enough battery power to complete the entire process. Also, backup all the data you have currently stored on your device as it might get lost during the update. Please note that Geeksailor cannot be held responsible in case something goes wrong and your smartphone breaks or in case you lose you data.

Now that you know all these you can move on to the installation guide and learn how to successfully apply the Android 4.0.4 Ice Cream Sandwich Update on your Nexus S 4G smartphone. First, you need to download the files you’ll be required to use during the update and you can do it by clicking on the links listed below:

Save all the files on your computer’s desktop screen and then follow these steps:

  1. Launch Odin by clicking on its executable file.

  2. Extract all the files contained within IMM26 Production Firmware.

  3. Go to ODIN, but make sure that you don’t change any of the default files / settings. Also do not even think about selecting the EFS clear checkbox as that will delete the PRL.

  4. Now we need to select the software files and first click on ‘Bootloader’, navigate to IMM26.zip and select the SPH-D720-IMM26-BootLoader-signed.tar (checksum: 7d8b0ad9617b832eeac8786dac2305a9) file to load.

  5. Click on ‘PDA’ and select SPH-D720LE-IMM26-PDA Signed.tar (checksum: e3c8e116fbb8668bf3ad0d0cd8b16ed6) file and then load it.

  6. Now click ‘Phone’ and select the SPH-D720LE-IMM26-Modem-Signed.tar (cheksum: c346cc28067305bec764f061d9a57098) file and load.

  7. Flash using Fastboot. Here are the checksums for the IMG files:

  • a4b95efbc4298105b52817104cb9d8e0 bootloader.img

These were all the steps that you had to take in order to correctly update the Google Nexus S 4G to Android 4.0.4 ICS and now the device should already have completed the reboot process and the Ice Cream Sandwich fully working.

For those of you that wish to wait until the official update gets released then you shouldn’t try to flash the firmware of your smartphone, as that date of the Icea Cream Sandwich Android 4.0.4 release might take place rather sooner than later.
