Icecream Sunday: Fastest Galaxy ACE Cyanogen based ROM with Overclocking

When we go for an Android smartphone we have some expectations. For this we keep looking for custom ROMs that can serve our purpose. But in general we find ROMs that offer maximum functionality or flashy looks.

Out Dated ROM.

There are many who need just updated and advance ROM without pre-installed applications or a fast ROM for playing games. Keeping all this in mind another issue that rises is the battery life the ROM is offering. It depends on our usage habits but still a light ROM can save a lot of battery. So here we introduce ICS for Galaxy ACE.

What is ICS for ACE?

Do not get confused. This is not Icecream Sandwich but an altogether different ROM Icecream Sunday, trimmed and modified version of Cyanogen Mod for ACE by XDA member Jusada. This ROM has been made trimming down all additional features and hence is a Cyanogen Mod based barebone.

How to Install ICS?

If you are already accustomed using custom ROM’s then the installation procedure is easy and the same. You can do it over Cynogen Mod, if you are already on it but make sure you have made a backup of ROM from CWM. If you are a new user then follow the steps below.

To upgrade to this rom you must be running on Ginger bread version 2.3.3, 2.3.4 or 2.3.5. If you are still running on froyo and need to upgrade to Gingerbread, here is our video tutorial on how to upgrade Galaxy Ace to Gingerbread. If you are updating from existing rom, back up rom from CWM or backup applications using Titanium backup.

  • Download the required files from XDA thread and copy then to your sd card.
  • Download and install CWM if you are not having it already.
  • wipe data factory reset, wipe cache partition, wipe dalvik cache.
  • From CWM install zip from sd, select the file you copied. Installation will take some time.
  • Restart System.

What Features are Included/ Excluded in ICS

There are no new features included, its basic CM 7.1. Rather there are many applications that are excluded like Maps, Gtalk, Gmail, Spare parts and many more including the live wall papers. To my shock I was not able to find the File manager app also but to a releif I found Market to be working and downloaded Es File Explorer. So you can only download the applications that you want.

The features included are Icecream Sandwich icons and Overclocking Kernel. When you boot for the first time you will find the status bar to be improper. Just go to Theme Manager and change the theme to ICS to solve this problem. While applying the theme you will get a warning message, ignore it.

How to Over Clock Galaxy ACE?

This Rom already has the OC kernel. You can directly go to Cynogen Mod settings> Performance> CPU Profiles and set the maximum frequency of your processor. Remember 921 is a safe value still tested beyond that I got instant restarts. What I will suggest is keeping the value to 848 in general cases, it worked stable and I tested it on few games with good results.

Note:  Overclocking is not a good practice. Only use this feature occasionally with restriction on the time limit. As overclocking causes overheating in prolonged usage.

    Hello everyone.
    This is the first time I really consider to install something to my mobile phone that is not official.
    I have no idea about htese things, so I would like to ask a few things before o continue with the instllation.
    1)Android market works like 2.3.3?
    2)I can install every app I like?
    3)If I don’t like the ROM, I can go back to 2.3.3 official Greek version, and if so how.
    4)Is it stable? Will I encoutre reboots, errors ect (im talking about the edition, given that I wont overclock)?
    5)The mobile works smoother?
    6)Any general limitations comparing to the official Gingerbread version?

    Thanks in advance and sorry for the big post.

      Your Answers….
      1) Ya android market Works as usual.
      2) Ya all apps work.
      3) Yes you can go back to official stock ROM, you have to use ODIN, here is how you can do that
      4) A complete Custom Rom is stable. If you are downloading a ROM which is in Beta Stages it might not be stable. Go to the XDA forum links provided here and read people’s comment to know more about their experience.
      5) Your mobile will be 3-4 times faster and smoother compared to Stock ROM.
      6) There are no limitations with custom ROMs with respect to Application installation. But if you are under warrenty, before going to service center flash back to official Stock ROM.

    First of all, I want to thank very much you for your reply. I really apreciate it.
    After a lot of reading, I would like to ask some further details about 2 things.

    1)If I install this ROM on my 2.3.3 firmware, am I going to be able to compose text messages in Greek?
    2)If I follow the above link and upgrade using Odin software to 2.3.5 am I going to be able to choose through setting the Greek language and compose text messages in Greek?
    The meaning of these questions is, if I have the official firmware (2.3.3 Greek form kies) and apply the ROM i will have the same language as the firmware, in this case Greek? So in this way if I install the 2.3.5 I will only have English menu/text writing?

    Sorry for staying to this, it may seems less important, but at the site:, I couldnt find downloads for specific languages, in my occasion Greek.
