This video will show you how to Upgrade Android from 2.3.6 to 4.0.3 (Gingerbread to Ice Cream Sandwich) Samsung Galaxy S.

Microsoft Store

Android Icecream Sandwich

This video will show you how to Root your Firmware
This firmware will show you to Upgrade Firmware on your Samsung device.

Step 1. Make sure your Samsung device is rooted. Link above.
Step 2. Download the Samsung Galaxy S Upgrade Ice Cream Sandwich Firmware from the downloads page here.
Step 3. Plug in your device and make sure that the device driver is working ok. You can do this in Device Manager.
Step 4. Open the Samsung device and view the files and go into the Android folder and copy the file you just downloaded into the Android folder.
Step 5. Power off your Samsung device and put the phone in recovery mode by holding down the UP volume button + Power button + Home button.
Step 6. In the menu select Wipe Data / factory reset, this will Wipe any data on your Samsung device so make sure you do a back up first.
Step 7. Wipe cache partition and go into the advance and Wipe Dalvik cache.
Step 8. Go back to the main menu then to go install zip from SD card. And choose zip from SD card.
Choose the Zip folder from the Android folder that copied to earlier and you are done.

The Android upgrade can take anywhere from 5 to 15 mins to complete. The Samsung Galaxy S model that I recorded the video on was a fair bit slower after the upgrade, but for some people they probably wont notice the difference and the upgrade Android has the benefit of the newer OS.

If you would like to see the Samsung Galaxy S specs you can find them here on the Samsung site.

Good luck.

    • Hi Ritik
      Try a power off and power back on.
      Remove the battery and let it sit for a few mins and then try again. If you have no joy try rolling back the software by following this video here.
      Once you have set the phone back you can try the upgrade again. Don’t forget to back up your phone at all times.
      Good luck

  14. Hi, I followed all your procedures and I got mine working thanks to you! But I really have this one problem with the sound, I think it doesn’t work? How does it goes for you? Everything was for me but no sound at all. Please help. πŸ™‚

    • Hi John
      No sound. I have not seen that issue before. You could try restoring the old firmware and testing the sound again then trying the upgrade again.
      Otherwise you could try a different version of the firmware.
      Have a look here.
      And here.
      And Root here.

      Good luck πŸ™‚

    • Hi godavari swetha
      Looks like its in factory reset mode.
      See if you can plug it into the computer and backup the data. Once you are sure you don’t have any data on the phone. First try a shutdown. Remove battery and sim for 5 mins then plug it back in.
      Try turning it on again, if you still get that screen try doing a factory reset.
      Good luck

    — Install /sdcard/Android …
    Finding Update package …
    Opening update package …
    verifying update package …
    E:signature verification failed
    Installation aborted.

  24. I successfully upgraded to ICS 4.0.6. However , my phone is not able to detect the network and am not able to make or receive phone calls.

    can you please advise on what needs to be done.
