Download & Install Official Android 4.0 ICS MIUI ROM for Samsung Galaxy S2

Any MIUI Fans here? It’s time for you to try out official Android 4.0 Ice Cream Sandwich MIUI ROM on your Samsung Galaxy S II. Not the SDK port version that I mentioned last year. There are several new updated apps in official Android 4.0.3 ICS MIUI V4 ROM like Lockscreen, camera, gallery, music… Try it to find out more.

Official Android 4.0 ICS MIUI ROM for Samsung Galaxy S2 is working fine. Most of the stuffs and features are working well during my testing. But the MIUI Launcher is a bit slow (not so smooth) compare to other ICS Launcher. No worry, MIUI team will fix all the bugs (sooner or later). They release a build every week on Friday. So do check on system updates then.

  7. Hi I have Galaxy s 2 GT-I9100 after upgrading via wifi. The Android ver is 2.3.5 and now am unable to use wifi

    I did factory reset still the same and cant use WIFI.

    Please advise


  8. Hello Jayce,

    See the below link from xda …this apk file is used to remove the yellow triangle and reset the counter of rooted cell……i tried myself and it has worked but this only works when u install rooted ics 4.0 …thought to share it with u so that u can show a video preview of this to all of our users so that they to can get use of this……..hope u do this

    • Hi Koppal, thanks for the info. I knew Triangle Away already. But not recommended to use because it modifies bootloader stuffs. You might brick your phone if not do it carefully.

      • hello jayce,

        thanks for the info…….i wont use that apk file again…….am lucky enough that after using that file my cell didnt get bricked….:)

  9. Hi Jayce i have a samsung s2 and i upgraded it in 4.0.3 version kernel version is 3.0.15-19100xxlpq-cl223505,, but i dont like it,, i want it to be back in 2.3.6. version,, I’ve tried to download the firmware but it wont open,, what can i do,, please help me,,

  10. Hey about the MIUI Theme.., i’ve install version of transformers pack but for some reason the theme doesn’t apply to the status bar and dialer theme. Plus,there’s some icon that suppose to be change according to the theme but it doesn’t.

  11. Dear Jayce,

    I am a strong follower to your site. Thanks for all the great guidance, I had managed to do alot of upgrading to my SGS 2.

    I’ve rooted my SGS 2 and is on CWM.

    I’ve tried the whole morning, trying to put the new Official Android 4.0 ICS MIUI ROM, as per your advise, on the SD card, in order to upgrade, but I am able to see the firmware file on the PC screen, however not during the CWM “Install Zip from SD Card”.

    Not sure what exactly happens. But would you care to describe if there is any special procedure to transfer the Official Android 4.0 ICS MIUI ROM to SD card? ( I did a normal Copy & Paste with USB cable connected to SGS 2 ).


  12. Hello Jayce

    Will u plz tell me whether I can install this rom on my samsung galaxy which was bought in China with following specifications.
    1. Model No. GT-I9100
    2. Android Version: 2.3.6
    3. Baseband Version: I9100ZCKJ1
    4. Build Number: Gingerbread. ZCKJ1
    As I have heard that its not possible to install any international rom on Chinese version, so plz guide me properly.
    Thanks and have a nice time

  13. Hi Jaycee,

    I successfully installed the miui firmware. Almost all the commands crashed beginning with installation of application at initial start-up. I wiped data, cache,and dalvik before installation. I just love this rom but it continues to crash. Never had this problem with other roms. Any suggestion?

      • Found the problem, it happened each time I restore system data from Titanium. BUT, the camera image is so mediocre. Its the worst I think. MIUI should offer a better tweak for excellent camera image (both and without flash). It looks like a 2 MP image now. Any help Jayce?

  14. Hi Jayce,

    I finally downloaded & installed Official Android 4.0 ICS MIUI ROM onto my Samsung Galaxy S2, Thanks for the help.

    I found out that it cannot connect up to Kies, to sync with Outlook. I used to be able to do that before upgrading.

    I tried to follow the instructions you gave on the other thread ” How to enable USB mass storage on Android 4.0 ICS Samsung Galaxy S2 ” ….. not sure right or not, but still I found I step missing on my S2 screen …. STEP 3 is not present on my S2 Screen, thus cannot proceed to complete till Step 7.

    1. Bring up Settings.
    2. Click More… (under Wireless and network).
    3. Then select USB utilities ~ Set USB cable connection mode.
    4. Select Connect storage to PC then.
    5. Connect USB cable from phone to PC.
    6. Select Turn on USB storage.
    7. That’s all.

    Grateful if you could advise how do I sync with Outlook 2007.


      • May I have your suggestion, how to connect via USB mass storage, to sync with Outlook, or is it not possible then.

        • I don’t have MIUI ROM on my SGS2 now. Can’t test USB mass storage. Try to play around the settings. Should be there.
          As for Outlook sync, you need to find 3rd party software to do so.

          • Ok, thanks Jayce. Will share upon success. Had tried out CompanionLink 4, but still cannot tweak it to work. But will keep trying others. Cheers.

  15. Flashed this Miui last weekend, to my utter disappointment it is awfully slow compared to Gingerbread. Serious lag with the default Miui launcher. Tried out other launchers as well, does not get any better at all, and there are some Chinese characters leftover. I love Miui, but this version doesn’t justify at all. I then flashed the latest Litening Rom, still playing with it thus far. Jayce, maybe you should do a review on Litening Rom. :p

  16. Hi Bro!

    I am currently using the S2 GT-I9100. Have rooted my handset and am on the official ICS 4.0.3(India).

  17. Cool Stuff!

    Just 1 more question as asked in the trail.
    Do i need to check my current firmware or anything before picking the custom ROM?
    I want to try the Revolution HD based on your recommendation.

    Do i need to do anything before installing the aforesaid ROM?

    Thanx once again and apologies for so many questions?

    I’m using Android 4.0.3 ICS with MIUI ROM.
    I browsed through the MIUI themes, i clicked open a theme(PRADA) and chose “APPLY THEME”.
    It then said applying theme, [2%…15%…86%…100%] and opened a window that showed me 3options >> CANCEL; APPLY WITHOUT FONT; APPLY AND REBOOT. i chose >APPLY AND REBOOT>ANDROID<<
    Do not turn off target!"


  22. For how long should i leave it switched off? i want my phone back to life. PLEASE help me. its been nearly three hours and i cannot live with my phone not working!
    tell me what exactly should i do now?

  23. i do not want any wipeout of the ics-miui…its awesome… i just want my phone to get back to working from this ODIN MODE that still persists. πŸ™
    i do not want any custom ROM. i just wanna go back to the ICS-MIUI ROM.

  24. I don’t think they will release the stable version soon, Jelly bean – maybe – will release this year !!!!

    For that, MIUI will not be stable for any version. So sad !!!

  25. Good day sir,
    I have a very serious problem with my phone (samsung galaxy s2 i9100 XXKPQ DDPL5).
    I tried rooting it with various packages available on the net. And after every procedure, used to check the rooting status via ‘Root checker’. Always unsuccessfull.

    Now what i did is downloaded MIUI ROM from net and copied it on my sd card.
    I also craeted a backup on my internal sdcard. N started following procedured of installation.
    Anyhow the installation wasnt successfull n i lost all my data. I tried to restore my default ROM, it ”Cant mount sdcard”. THn i tried mounting sdcard, it showed ”cant access path”.

    So basically im nowhere to go now. n want to install a complete fresh installation via odin.
    I dont see my phone on the pc anymore to copy files on its internal sdcard.
    CWM is working in the phone, ODIN is detecting the phone on the pc.

    Please advice ASAP. n also provide necessary links to the softwares to be downloaded, if necessary.

      • Thank u Mr. Jayce for giving ur precious time.

        I hav downloaded DexterMIUI earlier n tried installing it through Odin..

        Everytime i tried installing it i got an error saying ‘ Complete(Write) operation failed.

        Anything i try to install eg , Eugene 373 / I9100XXKP8– Ice Cream Sandwich for Galaxy S2 [Android 4.0]_files, gives me the same error Complete(Write) operation failed.

        Only the phone is acceting successfull installation of GT-I9100G_LP7_ClockworkMod-Recovery_5.

        Now my fear is, during the installation of official ics muiu, if the same error occurs, what is the solution. I mean what is the general solution to this error..

        Thanks again….awaiting reply..

        • Sorry Shoaib, I did not try these ROMs. No idea. You can try to restore back to stock firmware. Let everything clean as start. Then try new Android ROM.

          • Definitely I want a cleanup.

            Now there is a new issue, my screen has gone blank.
            Tried download mode, recovery mode, start mode, the phone is not respondiing at all.

            Is the battery not charging with the flashed status of my phone, is it so ??

            Or the handset is dead …

  26. Jayce,
