JCase has given us an app that roots the Eris with a click. Here's the link: 1 Click Eris Root App – No PC Required | xda-developers
I do have a question about it though. Superuser Permissions showed up in my app drawer, but it's just a black screen. How do I use it?
I've read that you have to use the Android SDK on your PC and type code to give certain apps SU permissions. Is there another way around this, or if not, can someone explain how to use the SDK?
