How to Update Epic 4G Touch to AOSP Ice Cream Sandwich ROM [Android 4.0]

ADVERTISEMENT

Here’s a new custom Android 4.0 Ice Cream Sandwich ROM for the Samsung Epic 4G Touch, which brings the AOSP Android experience to the device i.e it features stock Android as found on the Galaxy Nexus and other Nexus devices – no bloat, no unnecessary apps, etc, just plain, pure vanilla Android.

Jelly Bean Android 4.1 custom ROMs for the Epic 4G Touch can be found → here.

However, keep in mind that since this is a custom and not an official ROM, there are some bugs/issues in it, and Samsung/Sprint specific features will not be available in it. The current list of issues is given below (quoted from the developer):

Known Issues:
– Occasional LoS (Loss of Signal). Doesn’t affect everyone. Just toggle Airplane Mode.
– Camcorder effects cause FC
– 4g goes to “unknown” when first initialized. Turn on again it will work
– SU/Superuser are kinda wonky. Just “update” the SU binary.

Let’s take a look at how the AOSP Ice Cream Sandwich ROM can be installed on the Epic 4G Touch.

    NOTE: Don’t forget to at least note down your network’s APN settings, which are required to make mobile data work. Go into Settings » More » Mobile Networks, click on the APN that is in use, then note down the setting for each field. While APN settings should be automatically restored from network, you can enter them manually if needed to make mobile data work.
