    I’ll add this to the list of great ICS ROMS. So far my favorite ROM’s are SHOstock 2 & Phone-Bricker. Personal favorite is Phone-Bricker.

  2. fadhli says:

    i install this. So far so good. No problem so far. Does anyone know how to capture screen using this room? I try to do it by pressing home and power button, but it does not work.

    Didnt work for me

  4. Christopher Allen says:

    For those of us that aren’t as computer savy as others, how does one go about installing this ROM?

  5. Jay says:

    I’m liking this ROM a lot with all the AOSP apps. I just switched over from Phone Bricker to give this a try, however, Im getting a bit of home button lag… Anyone else?

    • Juan says:

      How did you switch over ?

      I have the leaked official AT&T ROm but not sure how to switch to this one.

      Did you unroot back to 2.3.4 then re-applied this rom or just loaded it from within the PhoneBricker?

      • Jay says:

        I was already rooted with CWM and just went into recovery and did a nandroid backup, then wiped, cleared cache, Dalvik, then flashed this ROM from my SD card, rebooted, then flashed the phone fix from my SD card in CWM recovery.

  6. Jon says:

    When trying to install the ROM, I am getting an error: E: failed to verify whole-file signature E: signature verification failed Installation aborted

    Can anyone help me?

    • LCH says:

      Were you able to flash it? I was seeing the exact same error. I had done a โ€œwipe data/factory resetโ€ on ClockworkMod Recovery before flashing the ROM and that was the mistake. Luckily, I had done a nandroid backup before my failed attempt and was able to restore my phone to its previous state. To flash this ROM got into ClockworkMod Recovery mode and install it from zip. You will get some sort of installation wizard (very easy to use) and in one of the installation steps you select the full wipe option. You also get the option to select one of three launchers.

    Installed few minutes ago. works flawless. but have email setup issue.
    How to add exchange account in this version of ICS. I don’t see any non-gmail email setup options. Please let me know if there is any or a way to sync exchange mails. Thanks.

  8. Michael says:

    Works pretty well, the only issues I’m having is that when trying to install non-google-play apk.. i.e. Amazon Market Place apps they just say that they are installing forever.. I’m also having issues moving icons from one screen to another, every once in a while it will cause Apex to core out.

  9. giulio says:

    works pretty well, and now I can record video in stereo….wow! Thanks.

  10. trepid says:

    Rom is working great! The only issue I have is that my Facebook contact pictures do not sync with my Google contacts. Any ideas or am I a moron?

  11. Julio says:

    Hi, i’m a newbie in android…

  12. AJ says:

    Now do all the ICS 4.0 not include the back arrow and the search button? I am looking for the one most like the Galaxy Nexus but none of the back arrows or the search button work

  13. RonR says:

    Can you do a review on ShoStock2 v1.3? I have recently installed it coming from Phone-Bricker 2.1 and I am curious on the new features and improvements. Thank You!

  14. Harry says:

    This is a great ROM, but I’m seeing a few random app crashes and some that happen all the time. The biggest one that bothers me is the fact that it’s impossible to select a custom ringtone. The contacts app just crashes whenever “Go to My Files” is selected as a ringtone option. I’m not sure if I’ll stick with this or go back to Unnamed.

  15. Owais says:

    • trepid says:

  18. CarlW says:

    Anyone having an issue with calendar app not syncing with exchange using active sync?

  19. Justin says:

    This is obviously a noob question, but how do you install this one? I don’t see a .tar in the zip file, just a bunch of folders / other files.

  20. addisu says:

    I am totally new to Android phone and just got Unlocked AT&T Samsung S2 two days ago.

    How do I install this “Ultimatum ICS ROM” ?

    The other question I have is, every time I send email from my phone there is a signature “Sent from my Samsung smartphone on AT&T” … but I am in Canada with another carrier. How do I get rid of this?


    • trepid says:

      The signature message can be changed in the settings. As for installing a rom start by
      rooting your phone, just follow steps on this site. How to root i777.

    • Josh says:

      im in the same boat. at&t phone in canada and i hate the signature. so go into the email app then open more(settings) and uncheck signature or just change what it says

  21. Justin says:

    Any one find a gps fix for this rom. Otherwise I love it.

  22. KS says:

    Works well except for a small issue. Am unable to get the get it to display only ‘My Contacts’ under Contacts section. Anyone faced/found a fix for this?

    Also, Zedomax can you please upload the boot animation of the Android disappearing in smoke?

  23. erik says:

    Why does he have the newer blue notification bar, but when I have this this ROM i still have the green one?

  24. erik says:

    Now that I got to use this ROM, it’s definitely my favorite so far. Make sure you pick Apex for your launcher and for your Theme pick ICS Theme, not stock, then it is much better. Thanks a bunch Max!

  25. Josh says:

    how do you install phonefix and why?

    • erik says:

      go back to clockwork recovery and flash phonefix, makes it a bit faster and fixes your network if it doesnt work because of some strange bug.

  26. gerson says:

    i have a little problems with this rom. when i call somebody and the call ends, the android.phone process fails. and the GPS doesn’t work. please what can i do

  27. Lex says:

    Just got this rom installed and working! tested phone without the phonefix, and yes you need the phone fix or youll get screenfreeze(sf) or and forceclose(fc), but with phonefix works great. ๐Ÿ™‚ did a full wipe and cashe clear before installing and i installed useing cwm 4.somthin from my internal sdcard, everything works great, except one thing lol, on the home screen the is the green smily box for messaging, when i click on it “This activity cannot be launched” reads across the screen. however i can go to contacts and send a message that way and receive them just fine.

    thank you zedomax for all your hard work ;), rate this rom as a 4.5 out of 5, (doesnt have cpu control ๐Ÿ™ )

    • yorch says:

      I was having the same problem but simply remove the messages shortcut and grab it again from the app drawer and put it were it was. That fixed it for me hope it helps

  28. bear says:

    This is my current rom right now, I have tried phone bricker but it wont let me drag files on my external sd card when i plug it on my laptop & noise reduction.issues every phone call.

  33. supertanch says:

    Tried this rom today, everything works ok except that everytime after i hang up a call, it crashes and sys Unfortunately, the process com.android.phone has stopped. Does anyone face the same problem? Also i’m not able to flash phonefix.zip.. it always aborted with signature verification failure.

  34. Sohaib says:

    this website has been very useful for me and it helped me a lot.. i have used serendipity9 with the latest update but found problem while making a call like when pressing the dialpad it freezes and also freezen when trying to call through contacts… i also used showstock2 latest but had a problem like the person i call is not able to hear my voice. Also used mysticglory and aokp7.1 but still got call echo problems… other than this all the roms are unique and really reliable. searched for more roms and came across this rom which looked promising.. gonna flash it now.. hope it does not have frustrating problems regarding call echoes etc..

  35. martin says:

    hi, I just installed this rom, works great, very fast and stable, but it doesn’t look like the one on the video, and it doesn’t have the same lockscreen animation when you push Power button to lock it (like a tv turnoff). could anyone help me? sorry, I’m new at this. for what I read, I have to set up or install an ICS theme, but I have no idea about how to do that. please if anyone helps me I’ll be very grateful.
