Upgrade Samsung Epic 4G Touch (Galaxy S2) to ICS Firmware FB09
There are two factors that hinder Android users from tasting the sweetness of Android 4.0 Ice Cream Sandwich on their devices—the device model and the carriers’ discretion. Fortunately, Sprint is alert to the requests of consumers and soon an ICS update will be expected on their Epic 4G Touch (Galaxy S2).
Although the update has yet to arrive, ACSyndicate developer Shabbypenguin was able to get a leaked copy of build FB09 of Android 4.0 Ice Cream Sandwich destined for the Samsung Epic 4G Touch.
The developer has taken the liberty of packaging the update into a flashable ZIP file. What’s more is that the firmware is already rooted, deodexed, and tweaked, so interested users only need to flash it.
So, if you’re eager to get the latest ICS, jump right in and learn how to upgrade your Samsung Epic 4G Touch (Galaxy S2) to a prerooted build FB09 of Android 4.0 Ice Cream Sandwich.
