Android 4.0 Ice Cream Sandwich (ICS) Update for Galaxy S i9000 [Custom ROM]


Galaxy S i9000 Android 4.0 Ice Cream Sandwich


While Samsung would take ages — if they intend to bring the update in first place, which itself is debatable — to release the latest Android 4.0 update to Galaxy S officially via Kies, our beloved developers have already started burning their midnight oil to get you Ice Cream Sandwich love on your very dear very venerable phone in android blogosphere, the Galaxy S.

And their hard work is showing up now in the form of a custom ROM — we’re talking about the first ICS (Android 4.0) port for Galaxy S, made by pretty famous now on Galaxy S development scene, Galnet.

Developers: Galnet was first one to boot ICS on Galaxy S but since then, he and his team has been quite on this. The development came to life only after Onecosmic started working on it and he is the one who took further, making it a bit usable and fixing the touchscreen and doing all the crazy part. After Onecosmic got busy with other stuff, work was resumed by PaulForde, who is responsible for current stage of rom, among with other devs who are working continuously on it right now.

Developers and Donation Link


Here is list to all devs who are currently active on this rom. And we hope you donate them to show your gratitude to them for work they have, while also encouraging them for working more on this development.

Android 4.0 Ice Cream Sandwich (ICS) ROM Status

Update (As of February 12, 2012): RC 4.2 is out — it’s simply one incredible rom, by certain awesome teams of devs.

Big Update: RC1 is out. Features working from this release: Video recording and playback, Hardware Acceleration, Calendar Sync, etc. You may want to celebrate this!! People avoiding the ICS — somehow, I mean — should try this version. Kudos to PaulForde (we’re really thankful to him for this) and Onecosmic.

Almost everything is working — though, of course, there are bugs!


[error]This guide is applicable only for Samsung’s Galaxy S international version — GT-i9000 and GT-i9000B. Check your phone’s version in Settings – About Phone. It has to be “GT-i9000” or “GT-i9000B” for this Android 4.0 port ROM to be compatible with your phone. Otherwise, simply don’t try this ROM on your android handset — don’t even think about it if you care about your android device.[/error]


[warning]The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to you or your device, we won’t be held liable — you only will be responsible, you’ve been warned!!![/warning]

Installing the Android 4.0 ICS custom ROM isn’t that hard if you’ve already done flashing stuff a couple of times. But even if you’re new to flashing and custom ROMs, don’t worry one bit, we’ve got you covered. Just watch the video below, read the instructions and you are good to do it yourself.

Pre-Installation thoughts:

  1. Installing/Flashing this ROM will erase your apps and data. So, it’s a very important you back them up, before proceeding further. To backup your apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. Restore APN settings if Internet isn’t working for you. This Android backup guide would help you. And if you’ve rooted your Galaxy S, you can save application’s data too, using Titanium backup (free app on android market) to backup apps with data. And use this this app only  again to restore those apps with data.
  2. Drivers! — it’s important you’ve the proper drivers installed. Download links below:
  3. If you have Samsung’s PC software Kies installed, be sure to exit it before using flashing this ROM, or anything with odin software.

Android 4.0 Ice Cream Sandwich for Galaxy S

Update: The installation process is much different now that what was for the initial release. But you can still watch the video — especially if you’re new to this — to get the idea of flashing and stuff. And the guide below has been duly updated to take care of installation needs of the latest release. So, go ahead!

So, the video below is not to be followed, but if you want to learn about rebooting into recovery, using CWM recovery, and other things, watching the video for once is recommended.

Here’s the video showing the installation of Android 4.0 custom ROM (AOSP port, version alpha4):

Note: There is a brief overview (from 6:58) of Android 4.0 running on Galaxy S in the above video.

How to Install Ice Cream Sandwich on Galaxy S [step-by-step guide]:

  1. Flash XXJVU Android 2.3.6 based firmware first.
  2. Install CWM and Root on the XXJVU.
  3. Download the latest version of “Android 4.0 ROM” from here — let’s call it rom file — and then continue the steps below to flash it without any worries. be careful while downloading since that page has downloads for all version of Galaxy S for which this rom is available. Download one meant for your phone, i9000.
  4. Transfer the rom file to your phone’s sdcard (don’t use external sdcard, btw). Remember the location where you transfer this files.
  5. Power Off your Galaxy S. Wait for 5-6 seconds until you feel the vibration to confirm complete switch off.
  6. Boot into Recovery mode. Then, press and hold these 3 buttons together: VolumeUP+Home+Power till the Galaxy S logo shows up on screen. You’ll boot into CWM recovery soon enough. (In recovery, use Volume keys to scroll up and down and power key to select an option. Use back key to go back.)
  7. Do Wipe Data/Factory Reset
  8. Do Wipe Cache Partition
  9. Go to advanced and do Wipe Dalvik Cache
  10. Now, flash the rom file. Select install zip from sdcard » choose zip from sdcard » browse through sdcard and select the rom file you downloaded in step 3 and transferred in step 4 above. Select “Yes – Install ______” on the next screen.
  11. After flashing necessary stuff, phone will boot up into recovery again. You will notice it’s a different recovery, colored blue now, and this is what was flashed in step 10 above to make the phone ready for installation.
  12. Now, flash the rom file again. Select install zip from sdcard » choose zip from sdcard » browse through sdcard and select the rom file you downloaded in step 3 and transferred in step 4 above. Select “Yes – Install ______” on the next screen.
  13. Go back and select ‘reboot system now’ to restart the phone. Be patient while phone boots up, it may take between 5 to 15 mins  for first boot.
  14. IF IT FAILS TO BOOT in 15 mins, then, well we got problem here. Do this:
    1. When the phone is restarting (still booting up) open the back cover and REMOVE the battery. Yes you read it right. Reinsert it after 3-4 seconds and then boot into recovery again.
    2. In recovery, do a Wipe Data/ Factory Reset. And then, select reboot system now to restart the phone. it should boot up properly now. If it doesn’t, then perhaps you did not follow something correctly.
  15. Also, if you are not happy with the performance of this rom — maybe because it lacks some apps/features you cared too much for, or reboots itself — I would suggest you to install the Android 4.0 AOKP Rom for Galaxy S, it’s simply damn good.
  16. [Optional] Support the development and appreciate the hard work put in by the team by donating them. Find donation link given above.
  17. Also, it’s already rooted. You don’t need to root it.
  18. Just for your info, Android 4.0 custom ROM is available Galaxy S2 too — find our Installation Guide for Android 4.0 on Galaxy S2 i9100 here.
That’s it. You’ve the Android 4.0 running coolly on your Galaxy S buddy. Cheers to awesome dev team!


Btw, if you want to revert back to Android 2.3 Gingerbread firmware from this Android 4.0 custom rom, get (install) the XXJVU firmware, linked in at step 1 above. And if wanted by you, root it as given in step 2.

    Hi, this roms work in Samsung Galaxy S GT-I9000T…?

  • Anand

    Kapil – thanks for the reply. I can live with that & also with not being able to set my music as ringtones.
    When will the next update be available?

    A major issue I faced is that sometimes when there is an incoming call, I cant hear anything on the phone (or on the handsfree). Issue gets resolved if I reboot. Any solution for this? I dont know when/how often it will occur.


    in that file which i download only ICS file is available.. other 2 files.. (Super user and Fugu Not available.. Help.. and Wi-Fi and Bluetooth does’nt turn on………………………………………….

    • http://www.theandroidsoul.com/ Kapil

      You can leave those other two files. The one file you got, is the rom file, and is enough.

  • RAhul Shetty

    Same problem here, Wi-Fi does not turn on.. help..

  • Anand

  • relhuk

    Hi thanks for this!
    However, I do not have ‘advanced’ option to wipe Dalvik cache.
    when I goto install from sdcard it checks for a few seconds then reads:
    E:signature verification failed
    Installation aborted…..

    Any suggestions?

    • http://www.theandroidsoul.com/ Kapil

      You do not have Clockworkmod recovery installed. You have to root and install clockworkmod recovery, it’s said there in the steps above. So, follow the guide above fully to the letter, and you will be fine.

  • Gynce

  • rmahajan9

    Guys, I had migrated to ICS RC4.2 ROM almost 3-4 months back and since then I had been enjoying ICS without much problem, everythings seems ok, except that I miss FM but thats not a big worry. One observation that I have is that quality of camera output of this ROM is much lower as compared to old Gingerbread 2.3.6 ROM or stock RoM for that matter. Inspite of some rich features in the Camera app of ICS ROM, the quality of pictures , specially during low light conditions. As such there are no Night mode and Stable shot options in scene mode at all. I also find few pictures missing after clicking them from the Galery and thats very infrequent. I just cant rely on this Camera app at all.
    Does any body else face the same problem with the camera?

  • Haider Abbas

    I have installed it and it work fine with same lag, but the Wi-Fi not working why?

  • Haider Abbas

    I have installed it and it work fine with same lag, but the Wi-Fi not working why?

    • D

      Same problem here, Wi-Fi does not turn on. It just keeps on showing the “Turning Wi-Fi on…” message. Any solutions to this?

      • D

        Never mind my last post, it is working now. @google-3e9dae559d01e2f3f58d46eaee175118:disqus: try flashing the rom again, that solved it for me.

  • Softlab

    THX for everything, but my FM Radio and GPS wont work. Anybody help?

  • Worldgame

    Update done perfect but im unable to conect to Kies anyway you can or not? Thanks

    • http://www.theandroidsoul.com/ Kapil

      Kies won’t work with this.

    • Sincere_696

      when your device is flashed kies does not work ,i think so

  • Jerrydenheijer8

    My phones doesnt shows an wipe dalvik cache or shows install zip. now it says signature verification failed. i already updated succesfully to 2.3.6. Any help?

    • http://www.theandroidsoul.com/ Kapil

      You don’t have clockworkmod recovery installed, man. You got to follow each and every step above. I think you skipped step 2 above, which installs Clockworkmod (CWM) recovery and also roots the XXJVU firmware you install in step 1.

  • Ugesh8055

    holy shit im not getting my network after update i9000

  • Wolframic

    Thanks man. Very cool, as Patrick “Just a quick note: in step 11 you said the phoneback into recovery mode. My phone does not. He skipped step 11, 12 and 13. After I selected the rom to be installed, it installed the rom and then resumed a few minutes he showed me the animated logo startup as 10 times, and then worked :) ”

    However I came across a bug: can not get into “recovery mode”. I have no problemgetting in “download mode” but I can not do the recovery, whether by thecombination of keys or through the mobile phone. you can help? 

    • http://www.theandroidsoul.com/ Kapil

      Thanks. It’s okay if it rebooted directly, good update by developer, actually.

      That recovery problem is strange. Do one thing, install the Quick Boot from Google Play store – https://play.google.com/store/apps/details?id=com.siriusapplications.quickbootand then open it and select recovery mode t boot into. See if this works, and let me know.

      • Wolframic

        The “Quick boot” does not solve de problem. It restart the phone twice but do not go to recovery and starts de phone normaly.To regain access of the “recovery”:- i have to downgrade to firmware 3.2.6. if we install the  AOKP rom (http://www.theandroidsoul.com/galaxy-s-gets-android-4-0-based-aokp-rom/) When testing the phone with this rom we have access to recovery.however I prefer the latest version of “Android 4.0 ROM” (ICS_4.0.3_MR1-RC4.2_I9000.zip)I do not mind if I have access to recovery or not in my phone, or if in the future i need to downgrade firmware to get recovery acesso. but maybe the resolution of the bug helps someone.I followed all the stepsmy phone is a Sumsung S I9000used for flashing:- Odin- s1_odin_20100512.pit- I9000XXJVU_I9000OXAJVU_OXA.rar.- CF-Root-XX_OXA_JVU_2.3.6-v4.3-CWM3RFS.zip.- ICS_4.0.3_MR1-RC4.2_I9000.zipFollow steps toturial studies as they are in more than once and the result isalways the same. 

        • http://www.theandroidsoul.com/ Kapil

          AOKP is a better rom btw for the amount of customization options it gives. You better switch to that one.

          • Wolframic

            thanks :)

  • Patrick

    Thanks man. My Galaxy S is now running ICS4.0. Just one quick note: in step 11 you said that the phone would return in recovery mode. My phone didnt. It skipped step 11, 12 and 13. After I selected the rom to be installed, it installed the rom and after a few minutes it rebooted, showed me the animated startup logo like 10 times, and then it worked :)

    Thanks againg :)

  • Binicoles

    but how come there is no link to download AOKP??

  • K9

    can this work on galaxy s i9003 ???? plz help 

    • http://www.theandroidsoul.com/ Kapil

      No :(
      Don’t try.

      • K9

        is there any other way ?

        • http://www.theandroidsoul.com/ Kapil

          Nope. Third time.

          When I said absolutely necessary, it meant there is no other way. Btw, you can restore lost warranty back by flashing a Samsung Indian firmware back. Simple!

    • K9

      GT I9003*

      • http://www.theandroidsoul.com/ Kapil

        Nope, again.

  • Binicoles

    ok kapil got it…but how do i flash the gapps?i dont even know what they are:)

    • http://www.theandroidsoul.com/ Kapil

      Should be linked in that page’s guide, or see my comment in comments section there. It’s simple: download the gapps’ zip file and flash it like flash rom.

  • Binicoles

    @kapil thanks for the suggestion.i have one question thou:in order to go to AOKP rom i have to go back to gingerbread or i can go forward with the ICS 4.0 i have previously installed?(sorry,new to this just want to make sure i do everything ok,as i had some prb with my SGS since i bought it:(

    • http://www.theandroidsoul.com/ Kapil

      You can go directly. Just download the rom and transfer it to phone and then flash from recovery mode. Also flash the gapps after flashing the recovery.

  • than.papanik

    Hello guys!after the installation i have problem with the external sd! the phone did not  read the files that external contains! any suggestions….?

    • http://www.theandroidsoul.com/ Kapil

      It should be renamed as external_sd in file manager. Look for that folder, that’s your external sdcard.

      • than.papanik

        i know that my friend! when i open the (external_sd) file there are no files! i have in external sd all my music files! when i open the music player the system appears all my music songs but when i go to file manager–> external_sd there are no files!

        • http://www.theandroidsoul.com/ Kapil

          Oh ok… don’t know what’s the problem, then… umm, maybe reboot it and it would read the files. Is it mounting on PC after you connect phone to PC and enable USB?

  • Binicoles

    hey guys…i have done the upgrade previously on my SGS and now the phone just freezes,exit camera by himself from time to time and works really really hard…tell me what to do please..should i install it all over again or what seems to be the problem?if i cannot resolve this can i switch to the upgrade from samsung kies?thank you

  • Sameer

    Hi, I installed ICS ROM on my galaxy its working fine.Thanks.
    Now when i am trying to connect my Samsung Galaxy i9000 to Samsung Kies to restore the backup, my phone is not connectint to it.I can see SD card in “My Computer” but Kies is not picking the phone. Please help. Thanks 

    • http://www.theandroidsoul.com/ Kapil

      Since this Android 4.0 rom is not a Samsung firmware, Kies won’t work. You will have to install Samsung firmware back, can install XXJVU or this latest one, XXJW4 — http://www.theandroidsoul.com/galaxy-s-gets-official-value-pack-firmware-xxjw4-includes-touchwiz-4/
      After installing the Samsung firmware, Kies would work and you can restore your contacts and every other data you backup up using Kies. use our android backup guide then (linked above) to make a backup without Kies so that it works on Android 4.0 ice Cream Sandwich too. It’s time you kiss goodbye to Kies!

  • Furrukh

    Hi guys, previously when I was on Froyo, I was able to make a video call through the 3G network. But after upgrading my Galaxy S to ICS, there is no option to make a video call. I know there are software like Skype, Fring, Tango. But what about the 3G Video Call. This function seems to be missing from the phone after its upgrade.
