  • In the Odin, by clicking on the below mentioned options select the corresponding files which you can select from extracted files.

PIT – u1_02_20110310_emmc_EXT4.pit

    2. when the screen is locked i can’t recieve calls
    3. the 3G connection is not working
    and sometimes “Settings” “Contacts” close with errors.

    i guess this release still has some issues they must workout, but all and all it seems very nice.

    hi neal,

    I have installed android 4.0 as per the instructions above and it worked fine. But I am facing a lot of issues, the data traffic aint working, many apps keep crashing. yeah, I have done the wipe cache in the recovery, but still the apps keep on crashing. so, I would like to go back to 2.3.6 and probably will install a more stable version of ics.

    Can I directly flash 2.3.6 using odin to go from 4.0 to 2.3.6 or are there any specific steps? wud be very helpful if you could post the link that explains how to get back to android 2.3.5 from 4.0 ?

    I am back to XWKK5 2.3.6 firmware. The firmware is too slow, crashes and buggy. My music player crashed, camera crashed, 3G/Edge did not work on Vodafone/Uninor Phone (Dialer) crashed when I missed a call. The version is far from being close to a stable release. I would not suggest anyone to install this on their phone. The roboto font looks beautiful and many new tweaks and incognito settings in default browser. I could not fiddle with the phone for too long as after 9 hours of install i lost my network connectivity too.

    But thanks a lot guys for uploading..I have tasted the ICS 4.0 and I’m even more excited and waiting impatiently for a more stable release.

    There are little bit issues: takes way too long to start after the process is completed, Hangs a little, side scrolling is a bit confusing ( sometimes it goes to next screen as it is supposed to or goes back which its not supposed to).
    But after an hour usage worked just fine.
    However there one annoying thing that i don’t how to take care of : Every time i click something on screen for ex: an app or settings, a RED BORDER RECTANGLE appear along side the screen’s borderline.

    Please let me know how to get rid of this.

        Yes I have.

        Just an FYI:
        Please note after further exploration and testing i would recommend not to use this update since it’s still in it’s alpha stage which is clearly visible. Its way to buggy, crashes a lot. Even picking up a call is trouble some (you have to tap the damn Screen multiple times).

        I have 3 Galaxy S2’s and tested this on each one of them. Same Result. Also benchmarking show horrific results which i have never seen on my S2’s till now. The XWKK5 was awesome.
        I would suggest to wait for a more stable version.

    if this is the same version as the one from androidflip.com, it doesn’t work that well. many unexpected errors and many functions not working as normally. still a long way to go to being stable.

    if this is another version, hoefully it is better.

    1. Cannot import contacts from my SD card.
    2. Force Close issue in many apps.
    3. No internet connectivity through packet data. Its shows the icon but couldn’t connect.
    4. Very laggy. it takes hell lot of time to type a message
    5. Missing the people apps and face reconition lock
    6. Problem with notification bar and home screen.
    7. Lock screen is different that basic icecream lockscreen
    8. Searc widget is the same old white background one.

    But you got hte latest task manager and its amazing rest i felt the same.Rest all is fine i feel and its usable.

    But please note i tried shifting back to 2.3.6 gingerbread but i was unable to do that. I may be making some mistake but just to warn everyone.

    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.

    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.
