  1. Hi,

    I’m kind of new to upgrading/flash android devices, i currently have a GT-I9000 running 2.3.3

    PDA : I9000XWJVH
    PHONE : I9000XXJVO
    CSC : I9000NEEJV3

    I’ve been waiting for ages for 2.3.4 and recently 2.3.5 to be available via Kies but no luck, seems Samsung have abandoned Galaxy S users in Scandinavia. Now they seem also to have abandoned us again when they have announced that ICS won’t be available either.

    I’m now willing to try your ICS custom ROM out but as i wrote i’m kind of new so i have a few questions first.

    1 – will the custom ROM support swedish character set ?
    2 – Can i just add the custom to my native 2.3.3 running recovery 3e or do i have to root the device first ?
    3 – Is there a way to go back to my previous factory/samsung rom ?
    4 – Is there a stable release coming ?

    Keep up the good work …


    • Answers to your questions:
      1. Not that I know of.
      2. You need to root it first… only then shall you be able to install titanium backup and get the backup of apps or take a full NANDROID backup from clockworckmod app and then get into clockworkmod recovery to flash the new rom/kernel/superuser
      3. Yes there is… you can download your current version from here, unzip the files and use the ODIN method to flash it. The pit file, that is not included in this zip can be downloaded from here
      4. This is much stable than previous versions. You can check with the users’ comments to know their experience good/bad/ugly. And yes, there will be a new release soon… How soon? Even I don’t know. But yes, if there is a new release, I’ll be back with it.. 🙂

      Hope this answers all your questions.

  2. works like a charm,big thanks to onecosmic,gti9000 is running well,phone can be used for daily routines,the ice cream sandwich 4.0.3 rc2.1 operating system is absolutely awsome…..thanks for fixing the links..

  3. Hi guys,

    Is there a version which can be flashed through ODIN?

    I had RC1 (on I9000), then I installed Glitch kernel, then ROM stuck in bootloop (as I see its cannot mount something, installation aborted but its rebooting immediatelly so I don’t have time to read it correctly).
    I flashed Darky 10.2.2 JVT 2.3.5, then tried again, same happened (I followed the procedure – coming from other ROM, factory reset, etc.)

    Any idea?

    Many thanks,

  4. hey, i’m using darky’s rom and tried to installa this ROM but it gives straight away “installaton aborted” in recovery, should i try to install first kernel and then rom?

  5. Hi Thanks for the post , can you please include Polaris Office or any office suite so that we can edit word and excel ,

    • Try clearing the cache and try again…
      If the problem persists… flash the fugumod kernel…. download link will be available in the RC1 Tutorial Post…

  6. How long time take the installation of the rom? I was waiting for 30 minutes and none action take place (the phone display the color squares animation…)

  7. i think i found an issue with ics 4.0.3 rc2.1 rom.
    when playing a video and you press the power button,the screen goes off and locks the phone,the video doesn’t continue to play.
    In gingerbread the power button locks the screen but the video continues to play.
    i don’t think ics should be like that, or is it?

  8. thx for your anwer, so the only way to connect PC is with “monut and storage” in recovery mode?
    BTW, can you plz tell me how to get battery percentage in notification bar?
    can u also tell me which kernal is the best(especially for gameloft games)? when i am on darky rom, some gameloft games FC.
    THX a lot..

  9. Plz some help me, when i choose and select rom file it just splashing through recovery and reboot. Can’t do anything,can only proceed to download mode. So i flash my previous rom(darky rom XXJVT-base RE)and do it again,but same happened. Is it because of my previous rom? Plz give me some suggestions!!!!

  10. sorry for just annoying, someone plz tell me how to set songs as ringtone, i can’t find ringtone option in music player…
    waiting for reply !!!

  11. hi for every one i just want to share my experince regarding ics rom even in this 4.0.3r1_Rc2. I installed and use it for 1 week every thing is ok fro normal daily use except for GPS support on this ROM. The themes and new icon is ok and acceptable but some features compared in gingerbread little bit away. like the following:

    For gaming HD games like Street fighter 4, Tom Clancy, Spider Man, Modern Combat 2, and 3, NOVA, always force closed all this game i played in gingerbread no other issue, also the game Dungeon Defenders and Eternity Warriors. I love playing games much more when break time in my duty to take a fast time so on that reason a come back again in stable gingerbread xxjvs 2.3.5 and evrything is fine.

    If you like the theme of ics you can download it in the market or use blackmart so you can download even the paid version of software in the market.

    • That’s true.But for me,only NOVA 2 force close.I haven’t try modern combat 3 yet,but I see someone in youtube playing that game in this rom.

  12. oooh! Not again! Android OS battery drainage bug. After using phones for ten minutes, Aandroid OS is 30% and quick battery drain :(((((

  13. i have instaled this ics it working very good but,i have:
    usb problem
    my pc cant see my gt i9000
    google+ is not working
    how to fix it

    • USB detection is a know issue and it is not yet working…
      google+ may not have released their support for ICS yet… will have to check it out and then let you know..

  14. Installed ICS on my Galaxy S i9000, but i cant change my ringtone to an mp3 of my choice, i have to choose from a list of preloaded ones. Does anyone have a solution to this???
