Update Acer Iconia A500 to Ice Cream Sandwich with Icylicious ROM. It’s Rooted Already.

The Acer Iconia Tab A500 recently saw the leak of an Ice Cream Sandwich Android 4.0.3 firmware for it, but unfortunately failed to run on most devices, rendering some of them unusable. But the modding community started work on it, trying to get it to run properly, and they succeeded allowing A500 owners to taste ICS on their tablets.

The latest on the development scene is Icylicious ROM, a custom ROM based on the leaked ICS firmware, that comes pre-rooted and without most of the pre-loaded Acer apps, resulting in a fast and bloatware free ROM. Almost everything in the ROM works, so it can surely be used as a daily ROM for those who want to do so.

Read on to find out how you can flash the Icylicious ROM on your Acer Iconia A500.
