How to Update Samsung Galaxy S2 GT I9100 with ICS Android 4.0 XXKP1 Firmware

Galaxy S2 Logo SpecialIce Cream Sandwich for Galaxy S2 GT I9100 is here and this time for a change, it’s a working version of ICS for Galaxy S2. The version which we will be going to see is almost near to stable build with all the basic things like Calling, SMS, internet works perfectly. This ROM has leaked from the tables of Samfirmware, thanks to them for satisfying the needs of the users to get this ICS build early than expected one.

Note: Please note that since this ROM employs the custom based kernel which is unsecured, it will count the custom Counter which will void the warranty.

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 Galaxy S2 GT I9100.

Now, let’s proceed to the list of pre requisites which you need to follow. But before that you need to ensure that you have created a backup of all the data which is there in your phone memory so that just in case if the data gets lost or corrupted, you should be able to restore the same. So, for your convenience we have mentioned the list of things which you need to do so as to backup or restore the data.

SMS – Use “SMS Backup & Restore app”,
ContactsSync 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

Note: Ensure that you have disabled all the Security Suites, Firewall 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”.

Instructions for Users on Custom ROM:
Just in case if you are ON any of the custom ROM firmwares then you need to first turn Off the phone and then you will have to enter into the recovery mode. The recovery mode can be entered by holding Volume UP key + Center button and then press the Power ON button simultaneously to turn ON the device in the RECOVERY mode.

  14. *Update – 2 hours later*

    -The phone is not as warm, and i haven’t had anymore crashes after rebooting the phone again and letting it run.
    -the keyboard issue is resolved by switching from the samsung keyboard to the android keyboard. No more delay
    -the browsing is SUPER fast, i am very impressed

  15. i just upgraded using your method to 4.0 and i’m not happy with it. every time i touch the screen there is a red lining on the outside of the screen, my data doesn’t work, and nothing is loading from my contacts or anything from the network. i want to go back to a better working firmware. what do i do?

  16. ok
    tell me
    whats not working?

    • some users mentioned about data not being working! minor issues with some apps as they tend to fc! or else it worked pretty goo, may be in the next version we will get to see some improvements!

  17. Hi Neal,
    Been looking forward, impatiently for the ICS update. Please I have a question about the camera, if it is working in this update as I recall, the Alpha and Beta had some issues. I am using my phone for everyday use, so can I use this update.

    Camera function is quite important to me so please update us on the things that are not working.

    Thanks Bro.

  18. Buggy as Buggy can get, stay clear of this till a better one is released

  19. The install was smoothe enough. However, the initial setup wizard kept crashing when choosing the option to set up a google account later. After i chose the option to sign in first, then i was able to use the OS. Things that i have noticed:

    1. There is an annoying red rectangular border that keeps flashing on the screen at various times
    2. The performance is laggy, especially when typing, there is a half second delay or so
    3. The phone is extremely warm
    4. Random apps crashing, including the basic ones like contacts and market place, even though i have cleared the cache partition twice

    Other than those issues, the new look is pleasing to the eye and i look forward to future releases of ICS. I made a call, so i know that the basic phone capability is working.

    Advice – Wait for the next release, as this one is not quite there yet.

  20. Neal,

    Is this the one like the cyanogen mod version of ICS or the one wtih the touch wiz on top… the one in the video at gsmarena…. thanks.. will try soon after i received your answer.. and is it good or i have to wait for cyanogen version?

  21. Packet Data Connection Is not Working….

    And Some Times All Standard Applications are Force Closed.. Including Contacts, Calling

  22. how stable is it ?

    I mean, can it be used for everyday activities or is it still kind of beta with possible bugs ?

    Also, will I be able to go back to 2.3.6 if I wanted to ?
