My Galaxy started giving me an info message "battery disconnected" and will not connect with my computer. It will still charge, but drains faster and doesn't recognize that a charger is connected to it. I tried every solution on the internet (new battery, original charger, clean terminals, clean usb etc) and nothing worked. I also tried every software option including going all the way back to unrooted gingerbread. I called samsung and they acknowledged that it is still under warranty and that I can send it back. SO, I am rooted and using "Touched By S4 version 2.0 GB27 Jelly Bean Deodexed for the Epic 4G Touch SPH-D710". I don't want Samsung to wiggle out of the warranty because it is rooted. What is the best way to remove all trace of any changes and return to stock? Thanks.
