Nexus S LogoIf you are having a Google Nexus S device and wondered when you too will receive an OTA of ice Cream Sandwich Android 4.0 version, in fact the latest Android 4.0.3 version of ICS. This update comes just after reports came in about an update of ICS Android 4.0.2 for Galaxy Nexus. This update for Google Nexus S users is no less than an Xmas Gift or say a New Year Gift. But hey, if you are still wondered on how you can apply this update manually then we will see in the due course of the article on how you can Manually Update Google Nexus S with Ice Cream Sandwich Android 4.0.3 firmware. This update is the latest in the history of Android and Nexus S becomes the first handset to get a taste of this firmware.

This update works perfectly on the GSM version and to sum it up this works for all the users on I9023T as well as on I9020 Models as per different sources.

Disclaimer: Please note that we should not be held responsible in any manner in whole or in parts if any damage is done to your device caused by updating the firmware which is a very unlikely event if you follow the instructions as mentioned in the article including the pre requisites and the procedure to update the phone.

Before proceeding you need to first go through the list of pre Requisites which are mentioned below.

Quick Pre Requisites:

  • Backup all the data present in your phone memory so as to ensure that just in case if any data is lost or corrupted, you can easily restore back the same. With the help of below mentioned tips, you can backup and restore the data.

Notes – Backup in the mail so that you can then restore manually
SMS Messages – Use “SMS Backup & Restore app”,
Contacts Stored in Phone Memory – Sync with the Gmail application,
Call Log - Call Log and Restore
Videos, Images, Videos & Files etc.– Copy to internal / External SD Card,
Internet & MMS Settings – Backup all the settings from “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • Ensure that the USB Debugging is enabled from the path Settings > Applications > Development > USB debugging as shown in the below image. Also if any Antivirus suites are installed in your phone, then remove or disable the same.


  • The phone should be on the Stock Firmware / official Firmware, if it’s on the Rooted or Custom ROM firmware then we can’t guarantee about the phone’s condition after this official update application. Also, phone should be left with the charge of a minimum of 50% so as to ensure that the phone doesn’t get turned Off in the process of firmware update.

Now, let’s proceed to the detailed procedure on how to apply this update in your Galaxy Nexus S which are mentioned in the next page.

  8. Device: Google Nexus S
    Country: India
    Carrier: Vodafone

    I upgraded from gingerbread 2.3.3 to ICS 4.0.3 thru the method mentioned above. Since then:
    1. the battery has been draining very fast
    2. the GPRS/EDGE issue that was there in 2.3.3 is still there
    3. when i restart my phone, the ringtone resets itself to any random tone (sometimes low battery tone becomes ringtone)
    4. some times when i get a call, an android system process crashes and i can either not pick the call or the phone hangs
    5. the little feature that made the phone screen switch off like a CRT monitor has now stopped working
    6. the inbuilt document reader for pdf does not render pdf properly – it sometimes does not show spaces between words
    7. the SMS app, document reader and some other apps have become painfully slow.

    I want to switch back to good old Gingerbread. Can you please, please tell me how to do it?

  9. I’m on a rooted device getting:
    E:Error in /tmp/sideload/
    (Status 7)
    Installation aborted

    any ideas?

  26. E: signature verification failed

    What’s this mean? That’s all it says after I select “apply update from sd card”

    It’s not installing on my phone… I’m on Mobilicity in Canada using a i9020.

  27. i don’t have \apply update from sd card\ in bootloader mode. what should i do?

    • you need to create the same!

      • How do you create the same? please explain, as i’m having this exact same problem, can’t apply update as have no “apply update from sd card”

        Please help.

    • Ok i figured it out:

      Switch off the device and then reboot into bootloader mode. (To get into the Bootloader mode, hold Volume up button and the Power button together.)
      Use the Volume key to navigate and select Recovery from the menu to boot into recovery, press the Power button to confirm.
      When you see the warning triangle and arrow, hold the power button and tap volume up. You’ll see a menu.
      Select “Apply update from /sdcard” and select the file from the list.
      Once the update is flashed, select “reboot system now” to reboot your device.
      Enjoy the cool Ice Cream Sandwich treat…=]

    it seems this issu is in number of countries!

  30. i have the same seems this issu is in number of countries!

  31. Hey guys,

    This worked for me

  32. I successfully did the upgrade. However I have two problems since then:
    1. I cannot download anything from Android Market. It says fails to download due to an error. I can download through WiFi though.
    2. The emails do not update automatically as they used to before.

  33. Fix the first line. “Procedure to Update Galaxy Nexus S with Android 4.0.3 ICS Firmware” Take the word “Galaxy” out of the sentence as this is not instructions for the Galaxy Nexus. It shows up on Google search and is very misleading ^_~

  34. Samsung Nexus S I 9023 in Romania updated to ICS 4.0.3 version IML74K. Until now works perfect. I haven’t loose any data or program during the update. WIFI works well. Enjoy!

  35. hi
    I have updated my nexus s to android 4.0.3 . but the wifi does not work at all. it cant find any networks and wont even scan. is there anything I could do to make it work ?

  36. Please I will like to know how this procedure, type of update works. I mean if I factory reset this phone, if I clears its catch will the 4.0.3 still be there like in the other process using odin.
    Is this something that goes with the memory once its formatted.
    I hope my question is clear. Thanks
