We’ve already told you how to upgrade the firmware of your Samsung Galaxy ACE S5830 to Android 4.0.3 ICS CM9 Beta 6 and Beta 7. But those are the older versions of CyanogenMod 9 and now we have the latest version which is the Beta 8.
Even so, please bear in mind that this is not the official firmware for Android 4.0.3 Ice Cream Sandwich. There’s no official ICS update for the Galaxy ACE.
With CM9 Beta 8, you will get a more stable firmware. This version will also address the random force close errors from the previous versions. Also, we cannot guarantee the outcome of this installation. You could get your smartphone bricked and totally unusable. Just don’t blame us for any damages that could happen to your phone. Therefore, flash this custom ROM at your own risk. If you know nothing about rooting and custom ROMs, better ask for help.
