Samsung Captivate i897 – Steps to Install Ice Cream Sandwich Android 4.0.3 Firmware

Samsung CAPTIVATE LogoFor all the users who are having the Samsung Captivate i897 device can now cheer as in the due course of this article we will check on how you can easily update your phone with the latest version of ICS Android 4.0 firmware update. Please note that this is not the official update released by Samsung Electronics and is the beta version which is built by some third party developers. So, before proceeding to the procedure on how you can apply this update, you first need to go through the list of pre requisites followed by which we will check out on how to apply this update on your Samsung Captivate i897. There is still no exact date revealed by Samsung Electronics on by when the Official update of ICS Android 4.0 will be pushed to the devices.

Recently, we saw on how you can update Galaxy Nexus, Nexus S, Galaxy S with the latest version of Ice Cream Sandwich Android 4.0 version and now its time for Samsung Captivate i897 to get the ICS taste.

Disclaimer: At Android Advices, we have made sure in all respects that all the information regarding the firmware update is mentioned correctly in this article. We hold no responsibility in any manner just in case if any damage happens to your Samsung Captivate i897. As of now we have no facility to guide you to help you revert back to your current firmware from this ICS firmware. But its requested that you make a note of on which firmware version you are on, so that it will help us to guide you in future just in case if you wish to go back to the last version.

Quick List of Pre Requisites:

  • In the due course of the process, there is a possibility that the data may get corrupted or lost, so backup all of them using the tips which are mentioned below. Don’t use KIES to back up the data, as you will not be able to use kies after the update as till now SAMSUNG hasn’t rolled out ICS Android 4.0 support for Samsung Captivate i897.

SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Call Log - Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • Disable all the Security SuitesFirewall tools and also the KIES PC Suite as these tools tend to interrupt the process of firmware update. Also, additionally enable the USB Debugging from the path “Settings > Applications > Development > USB debugging” as shown in the below screen capture.
  • Ensure that the device is Rooted and is left with the minimum of 60% so as to ensure that the device doesn’t get turned Off in the middle of firmware application.

Instructions for Users on Custom ROMs:
Just in case if you are on any of the custom ROMs, then you need to first enter into the recovery mode. The recovery mode can be entered by pressing Volume Down Key + OK button, and holding both simultaneously press the Power Button. In recovery mode, select options “Wipe data/factory reset”, “Wipe Cache partition” and after this you need to also select “reboot system” so as to restart the phone.

Once you are done with this, you now need to proceed to the procedure which is mentioned in the next page.

    I’ve flashed my captivate and it worked very mine once rooted of course.

    Now I’ve just one bug but of huge concern: the cut and paste with the contextual menu doesn’t work!
    The symbol does appear but no icons to cut, copy or past.


    • JXO

      working fine now, disregard my previous mail.


  • Jason

    Just Download the Speedmod kernel and flash it via ODIN and reboot in recovery after it loads
    and now u will be in a modded 3e recovery with signatures disabled

  • Me

    For those that are getting the signature verification failed message, make sure you toggle signature verification off. I had this problem with a previous ROM and my phone WAS rooted. Toggling it fixed it.

    This ROM works perfectly on my Captivate. No problems to report yet.

    • peachstateboi

      now how do you toggle the signature verification off might have helped to explaing that in your post

  • Phonesmith

    I can boot to the recovery screen
    here is what I do
    apply update from sdcard
    I select ROM zipfile from SD card
    I get:
    finding update package…
    Opening update package…
    Verifying update package…
    E:failed to verify whole-file signature
    E:signature verification failed
    Installation aborted

    What am I doing wrong ?

    Thanks for the help :-)

    • Pradeep Neela

      before updating, you need to root your phone!

      • Richard S. Wachtel

        you idiot, he said the phone is rooted, so i think he already knows this!

      • Arron

        Please Clarify what you mean by ROOTED

  • djaypresley

    I can not get it to flash on my phone. I keep getting errors ever time I try to flash anything.

    It says

    E:failed to verify whole-file signature
    E:signature verification failed
    installation aborted.

    What do I need to do. I can’t even get it to link to the computer.
    Please help!

    • Pradeep Neela

      you need to root your device before applying this!

      • Pradeep Neela

        install the recovery from the ROM MANAGER APP

    • smart

      flash to stock first. Then flash the new ROM on top via clockwork. If your a Rogers customer running the latest stock ROM you will have alot of trouble. There its something in that ROM that screws with clockwork. You may even need a jig to get into download mode before flashing back to stock 2.1 which is where you want to be before flashing any new roms until Rogers fixes it, which they will not do. It gets a little more complicated after that. You will likely have problems. You are rooted! The problem isn’t your root or super user. Its the ROM no matter what anybody else says you are rooted or you wouldn’t be running whatever custom ROM your running now. Root doesn’t just fall out of your damn phone. Its not an iPhone.

  • ZQSays

    These guys r ryt . they have rooted phone still they get “SIGNATURE VERIFICATION ERROR ” Coz Google has added dis Option dat u cant install an UnSigned package on android from 2.3 Onwards !! Find a soln. for dat , even on a rooted device !

    • Pradeep Neela

      it doesnt work on n/w locked devices, unlock the device first!

  • Nathan

    Before anyone does this they need to go to the official android developer page from where this guide was created. The people here do not know what they’re doing.

    • Pradeep Neela

      we have provided the detailed instructions, you can match the instructions!

  • Nathan

    If you are going to provide the .zip file for this port, then please at least point everyone to the website where it is actually being developed. To everyone with questions, please go to the link below. This is the managed forum with actual developers that are working on this port. They also list all of the known bugs/issues/etc. They also don’t use all caps when answering questions. This page is just a regurgitation of the information from the original thread.

  • Harpreet

    • Pradeep Neela

      Root the device, its not rooted.

  • peter

    I don’t know why exactly – maybe something to do with installing multiple ROMs and recovering back to CM7 (with a flaw* now) and re-kernalling etc. then even trying to re-ROM CM7 – which it wouldn’t allow anymore – but now even the tethering works – with a little fuss – having to go back to the carrier page and re-checking enable data – then back to the wifi tether page and re-checking etc. – but it all works now. Funny though – I can’t get back to CM7 on recover without a google talk *unable to authorize flaw – and I can’t figure it out. I never signed on to google talk. Dang thing. But anyway – I got ICS now and it all works. Thanks for that.

  • peter

    everything seems to work but for wifi tethering.

  • Joel


    I have a set of questions:
    – in case we installed Voodoo lagfix (ext4 file conversion) do we have to revert back to original file system before updating?
    – Does this ROM contains swype?
    – can you still switch from one language to another during message composition?
    – do you have a list of non functional subsystems? (eg. camera, music, email, wifi, 3g)..

    • NeaL Pradeep

      yes it has swype!

  • chris

    The phone wants a signature verification. What is that? The phone is rooted and I have have clockworkmanager recovary installed. I also have superuser installed.

    • NeaL Pradeep

      the phone is not rooted, root the phone first!

  • tallpaulyall

    It seems my wireless radio is only on when wifi is enabled… Is this common,or am I doing something wrong????

  • zee

    hi, i tried doing it and it keeps putting my phone in android system recovery 3e. I tried flashing with rom manager the captivate rom but still sent me to recovery 3e. Any suggestions?

    • NeaL Pradeep


      • zee

        yeah it’s rooted

    • Eric

      Same thing always happens to me just go to clockwork mod rom manger, make sure it says you have the latest clockwork mod recovery at the top, choose “boot into recovery,” recovery 3e will be there, choose what I believe is the first option something like “install update packages” next thing you know you’ll be in clockwork mod recovery and you won’t see the 3e anymore after that.

      • Pradeep Neela

        it needs to be rooted first!

  • chris

    I rooted my captivate and can see the superuser app. I have 2.3.3. However when I update, the process stops and says can not verify it. It identifies the zip file. How do I verify it?

    • NeaL Pradeep

      as of now we havent come with the rooting process, we will come up with the same!

  • Kaushik

    What is the best way to root my Samsung Captivate? Is there an article I can refer?


    • NeaL Pradeep


  • Kyler Davidson

    My mobile data quit working and I had to contact AT&T and they just had to re-register my phone. No big deal. Phone is super amazingly fast, and there does not seem to be any of the afformentioned lag. Love the lock screen and Notification tones, and the H+ capabilities!

    • NeaL Pradeep


  • james

    When I’m installing from the SD card the installation aborts stating the signature verification failed. Help.

    • Pradeep Neela

      it means that the device is not rooted, please root the same!

  • Paolo

    Do I need to disable Voodoo lagfix before applying the update?

    • Pradeep Neela

      yes you need to disable the same!

  • Dio

    Thank you for your fast answer.Yes, i can see the Superuser app, and i’ve also used it for programs like titanium backup.

  • Joe

    What doesn’t work ?! In this ics rom?!

    • Pradeep Neela

      almost all the apps work in this firmware!

  • Dio

    Hello, It doesn’t work on my rooted galaxy s captivate I897UCKJ3. It tells me installation aborted and does nothing

    • NeaL Pradeep


  • JOE

    could someone please post the list of bugs and issues of this rom….
    please let me know about its problems
    thank you

    • NeaL Pradeep

      almost all the functions work!

  • Charley

    A few quick questions:

    1. Will it lose all my apps and I have reinstall them? Or will it same them? How about apps I move to the SD card?
    2. Will root still work after I am done? Do you have a root app?
    3. How is the GPS support on this version?
    4. Any reason that you can think of not do to do this?


    • NeaL Pradeep
