It has not been long ago since the Android 2.3 Gingerbread firmware update for the Samsung Captivate was released, and now an Android 4.0.3 Ice Cream Sandwich custom ROM for the Captivate is finally available.

However, this ICS firmware for the Captivate is unofficial and Samsung Electronics has left us with no clue on when the official ICS update will be coming.

Many users have already experienced Ice Cream Sandwich on their devices (mostly through custom ROMs), but many have still yet to try it on their devices. So, if you are one of those who are still craving for ICS, download and install this firmware to your Captivate now.

To help you decide if you want to continue installing this update, go over the list of the features of this firmware, as noted by the developers:

  • Based on AOSP sources for Android 4.0.3
  • Google Apps
  • Platypus used as kernel base
  • Pre-rooted ROM, with init.d support
  • Full hardware acceleration, calls, SMS, data, audio
  • Fully working touchscreen, Wi-Fi, GPS, and Bluetooth
  • internal and external SD cards working fine
  • Calendar sync
  • Camera (Video Recording & Pictures)
  • Touch to focus, Panorama mode
  • Face Unlock
  • Wired and wireless tethering
  • FM Radio (AOSP does not support FM, download Spirit FM from Android Market)
  • Fully working sensors
  • Live OC support (download NSTools from Market)
  • USB OTG support
  • Voodoo Sound
  • Voodoo Colour
  • Battery Life eXtender
  • Deep Idle

Take note that this is unofficial ICS firmware for the Samsung Captivate and it is only applicable to rooted phones. When you root your phone you will not be able to claim warranty anymore. Another thing is that this firmware should not be applied if your device is network-locked.  Doing so may cause your phone to be bricked. Also, this guide is only for the model I897 of the Samsung Captivate.

    1. “Samsung Electronics has left us with no clue on when the official ICS update will be coming” – Incorrect- I think they’ve given a very definite indication that the Captivate will never get an official ICS update.

    2. “FM Radio” – Wrong again: The Captivate does not FM radio capability in the hardware, so that app will not work.

    Kinda looks like the author didn’t do much homework.

      Also, how useful is face unlock on a phone with no front camera? just feels awkward….

    I installed the 4.0.2 without much problem–only had to do it twice. It works fine except that now Kies does not show it connected so can’t transfer itunes music to it.

  • Disappointed

    Hope everyone noticed he said this update will only work IF your phone is rooted and more importantly IF it’s UNLOCKED as well. It may KILL your phone if it’s tied to a network like AT&T, Version or whoever.
