Typically, going back to a stock ROM after flashing a mod, a theme, a script or a modded ROM can be quite a long process. Sometimes, annoyingly so, especially if you don’t have a copy of the stock ROM laying around on your Android device or your computer. In the end, you end up having to format your system, flash the stock ROM and spend the day setting your phone up again.
For those carrying the Samsung Galaxy S I9000 and running Ice Cream Sandwich, there’s an easier way. XDA Senior Member jenablinsky has released a small mod that will restore the SystemUI.apk and framework-res.apk back to stock ICS which removes all the modifications made to it. Simply flash the small, portable friendly .zip in ClockworkMod recovery and you’re back to square one with a clean slate and, as opposed to carrying around a nearly 100MB ROM in the off chance something goes wrong, you’d instead just need to carry around a measly 14KB .zip. That seems much more reasonable.
For anyone running ICS on their SGS and need it to be less of a mess, then ignore my horribly poetry and head on over to the original thread for all the download links, change logs and instructions.___________________
