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.

  7. 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.


  8. 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

  9. 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.

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

  10. Hi, Having difficult upgrading to ICS

    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 ?

  11. 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!

    • you need to root your device before applying this!

    • 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.

  12. 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 !

  13. 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.

  14. 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.

  15. now the phone is recognizing the file..but same problem as harpreet.
    my phone is rooted for sure. still says E:signnature verification failed and it aborts installation .

  16. Hi..Im facing a strange issue. I downloaded the zip file and copied it to my sd card. If i see the file from the \my files\ option in the phone..the file is seen…however the same is not seen in recovery mode.

    Tried downloading afresh twice and repeating..but still the same.

    My phone is rooted.

    pls help thanks

  17. its rooted i have superuser

  18. when i try to in a install it keeps on saying E:signnature verification failed and it aborts installation can you help me

  19. 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.

  20. everything seems to work but for wifi tethering.

  21. Hi,

    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)..

  22. 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.

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

  24. 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?

  25. 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?

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


  27. 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!

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

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

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

    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?
