I received an Android tablet from my grandmother a year or so ago, and I'm finally getting around to using it. However, I don't want to use the Android operating system. I would much rather use Linux. Of course, to be able to install Linux, I have to "root" the operating system. I tried to install the Google Play Store in hopes I'd be able to install a rooting program, but even after trying 3 different versions, I've had no success. How do I root Android Ice Cream Sandwich?
