    Currently, the two most severe bugs keeping me from using this firmware for regular use are:

    1. Exchange account does not work. When I try to set up a new account in social hub, I get the error message “Unfortunately, Email has stopped”

    2. Widgets and icons on the home screen disappear after a while, leaving only the wallpaper visible. I have to restart the phone to continue.

  38. i hav done all the necessary actions and i was waiting for the phone to auto reboot but its still not doing it. its stucked in the downloading mode

  46. ok update ROM works fine but it doesnt have the ics Theme .. where can i get it from ? THankk you

  47. hi, it feels as though the bluetooth is somewhat slower compared to previous firmwares. is this a fact. current speed is about 47Kbps. i also had a wifi problem for a while- it stayed for long on authentication.

    overall- great. thanks.

  48. Guys, great to have a test on the new 4.0.3. Except for the occasionally hung, I did find that the new ICS the worth the try. I did find the apps icon are displayed much faster than before in the Market. To move the apps from one page to a new page is much easier than before. I will continue trying it.

    Thanks guys for giving us a chance to try this out.

  49. I had the same issues as Pinaki and CG mentioned.. Im back to official 2.3.6.. will wait for another update and many thanks to this website for letting us try atleast every leaked update.

    can I get any improvement if I update to ICS.

    Pls. Reply….Thanks!!

    Fahmid.

  51. Dear Pradeep
    Please help.I cannot install contacts through google sync.Please advice how to do it.

    Thanks

  52. hi. i just want to know what would be the difference between this update (using Odin) and the official update from samsung (using Kies)? Would they work the same. Thanks.

  53. Installed ICS 4 last night.

    Few observations – Same as Pinaki’s
    - Most of the changes seems to be with Google stuffs only.
    1. Battery consumption – still high.
    2. Kies does not work >> It works for me – Phone is detected and I can browse through contents but no updates as known.
    3. Some time home screen freezes and none of the icons are visible – Nothing helps other than restart/force shutdown. This happens very often.
    4. When you select for restart option it does not restart, you have to force shutdown – True, Had to remove battery a couple of times ;-( (Note: just installed last night and had to do this couple of times within)
    5. Many of the market applications does not install and report “file not signed properly” > Installed apps from backup doesn’t show anymore in Market under MyApps for further updates.
    6. Under software update my product does not get registered and report back error.
    7. Visual appearance – nothing great. Kovdev ICS theme was excellent when compared to this.

    Team, Thanks for your efforts!

    Hi Experts,

    I installed ICS successfully but following are my observations. (Cache cleared, Kernal Installed, Also factory reset performed) Before reporting I even re-installed the OS 2-3 times to ensure I am not missing anything, (No firewall or AV activated during installation process)

    Working on this since last more than 24 hours

    1. Contacts which were backed up could not be restored as it does not import form SD though the option is available, but when you manually go in to the folder and click on the backed up contact file it start to download one by one but then hangs after some time. This is a major issue and need to be fixed immediately or else update is waste of time
    2. Kies does not work
    3. Some time home screen freezes and none of the icons are visible
    4. When you select for restart option it does not restart, you have to force shutdown
    5. Many of the market applications does not install and report “file not signed properly”
    6. Under software update my product does not get registered and report back error

    Will report further as I move forward

    Cheers
    Pinaki

  55. Hi Pradeep – I have always been following your website & found it really helpful.Your work is highly appreciated.

    This particular version was successfully loaded onto my S2 ,however i ended up with lot of issues.

    For instance when i tried opening my contacts it just hung & nothing happened. I cleared the cache as advised by you on many posts.But that dint help.

    So im forcibly going back to 2.3.6 . I will probably try the ICE CREAM when its totally error free :)

    Thanks for your help again

    • as of now there is no eta on the same but be rest assured that as in when it gets released, we will post the same within a flash! :)

      Thanks for your trust in us!

  58. Hi Neal,

    Hi Experts,

    Thanks for publishing the update. Here are my observations after the installation

    1. My contacts are the most important to restore, I tried to restore from the SD Card backup but it simply hangs for some time and then notify that file format not supported were as in 2.3.6 it got updates very easily.
    2. Phone still hangs and report force shutdown of different application
    3. Many application from the market does not get installed and report \file not signed correctly\
    4. Kies connects and functions but it does not take the backup from the software.

    Please help how to restore my contacts rest is ok and will wait till next release

    Cheers,
    Pinaki

    • you should have used the backup procedures which we repeatedly mention,
      clear the cache and install the kernel as mentioned in the article!
      kies will take the backup but for that you need to install the kernel first!

  60. Hello Pradeep,

    Just applied this update on my device since yesterday. However, I have noticed 4 major issues so far.

    1. Randomly Reboots (even without doing anything).
    2. GPS seems not working
    3. WIFI gets diconnected.
    4. Software update fails and could not get rid in the notification bar.

    Thanks for your feedback.

  61. Hi There

    I have done the upgrade to 4.0.3 and also done the Kernel – I have got the following problems/fixes for you to work on
    1. Screens lock up (as mentioned above) get blank screens and I just get the wallpaper and no icons etc… I have to re-boot to get things going again
    2. It keeps coming up that Exchange has stopped (I am using a email with MS exchange) but keeps stopping ?
    3. When new email arrive the icon does now not show how many unread email you have – but this works on SMS icon.
    4. Very difficult to setup 2 different wifi connecntion – have to go through the setups and it would not scan for new connection, but after a while I got it to get a new connection and I added it. When you reboot you ohine it does not pick up the wifi connections if you have more than 1 ??
    5. No weather comes up on the lock screen when you have PIN !
    6. When doing Text messages there is no TX9 coming up even though I have selected a predictive word but nothing !
    7. Battery – not lasting very long – previous version 2.3.5 lasted longer!
    I do understand that this is a pre-release – but though I would give you some feed back to see if anyone else had these problems etc.
    Great work on bringing it out prior to the official release :)
    Thanks Heaps
    Rob

  81. Neal,

    Thank you very much for fixing the link. What is new in this firmware? can we still the orange thing when scrolling from panes to panes? What is improved in this fw? would this be okay if later on ICS will be released for S2? Many thanks..

    Francis

  82. OH! It looks so pretty and awesome! Thanks for working so hard for all of us, guys!

    Since “rooting” is not available, is there a current solution for me to use Titanium Backup Pro to restore all my apps? I live and work on a university campus where we must authenticate through a proxy server to access the internet. Since our city hasn’t reached 3G yet, it will take ages for me to reinstall all my apps using 2G.

    Any suggestions or ideas, or when we might see a rooting process?

    Again, thanks, guys! :-)
    Cole

  87. Hi Neal,
    Whats not working in this Beta?

    Regards,
    Atik

      • Hi Pradeep,
        Sorry if I was not clear in my question, all I needed to know if this firmware was stable enough for everyday use? I tried this firmware and these are the few things that I noticed: The Firmware still has bugs, Runs Smoothly in scrolling, but tends to freeze every now and then. Connectivity still has issues. Syncing contacts with gmail is buggy. Great if you want to try it out but I would not recommend it for daily usage. Will wait for much stable release. Camera worked on the first use but after that there was errors.

        Regards,
        Atik
