    Owners of the Samsung Nexus S can now enjoy the latest Android 4.0.3 Ice Cream Sandwich on their phones. Google has finally released an over-the-air update package for the Nexus S. Some have already received the update, while others are still waiting for it to arrive on their phones.

    Unfortunately, the update seems to be only for the T-Mobile and retail variants of the Nexus S. This means that the update does not support the AT&T variant of the Nexus S yet.

    If you can’t wait to get your hands on the newest Android experience, we have provided a step-by-step guide on how to manually update your Nexus S from Gingerbread to the sweetest Ice Cream Sandwich.

    Precautions

    Take note of the following important things you need to know before you proceed with the updating process:

    • This update supports T-Mobile and retail (GSM) versions of the Nexus S. If you have the AT&T variant or the CDMA variant of the Nexus S, the procedure below may not work.
    • If you have rooted your Nexus S or have a device running a rooted stock ROM, you will need to unroot it because the update will fail on a rooted devices. Revert to a stock Gingerbread ROM before proceeding with the update.
    • Update your Nexus S at your own risk. We will not be held responsible for any malfunction or damage arising from your use of the information provided in this post.

    Step-by-Step Instructions

    1. Download the Android 4.0.3 ICS OTA package update here.
    2. Rename the downloaded ZIP file to update.zip.
    3. Connect your phone to your PC via USB cable.
    4. Copy the ZIP file into your phone’s internal storage.
    5. After saving the files, disconnect your phone from the PC and turn off your phone.
    6. Reboot your phone into bootloader mode by holding the Volume Up key and Power button simultaneously.
    7. Once booted into bootloader mode, select Recovery from the menu to initiate recovery mode. Use the volume keys to navigate between options and the Power button to select an option.
    8. When the warning triangle and arrow pops up, press and hold the Power button and then tap the Volume Up key.
    9. A menu will appear. Select “Apply update from /sdcard” and choose update.zip. The update process will start immediately.

        root folder when you plug your phone into your computer.

    • Bikatron

      To all those who updated, could you please let me know what the battery power now is like ?, because google had paused the OTA update following complaints of poor battery life so just wanted to know if anyone is experiencing any such problems. Also can I do this update from 2.3.4 or does the phone need to be in 2.3.6 before the update.

      • kennyg007

        I updated from 2.3.6 so I don’t know but I would update to 2.3.6 first just to make sure.

        Battery: seems okay – mostly screen use.

    • Sylv_ester35

      Work on Nexus S, Videotron, Montreal, Canada
      Before 2.3.6 I9020XXKI1
      Now 4.0.3 I9020XXKI1
      Apps, phone book every thing else in place did not lose anything
      BEAUTIFUL…. LOVE IT

      After update had to reconnect to videotron network, and was faster than before.
      Wi-Fi works fine.

      • Blade86sam

        Strange I didn’t have to reconnect to anything after update, everything was working 100% perfectly and smoothly. But i do agree, connection to the videotron network is a lot faster then it was when on 2.3.X :)

        i also found the WIFI signal to be a bit stronger then it used to be, i could be wrong but i feel like it is, nevertheless this version is hands down way better then the stock gingerbread version.

        oh and i’m not sure if you had this glitch at the lock screen back in 2.3.6, but when i booted my phone, from off, and got to the lockscreen, when i dragged the “lock” slide, the word “Unlock” didn’t show until i unlocked it for the first time, afterwards it was there… weird right? at least now i don’t have to worry about that in 4.0.3 haha :)
