Since this is the General section and all new users will be collected in this section (because they cant post in the Dev section yet for good reasons), we will start at the beginning and assume you have a fresh new device. We will go over the steps from first to last on how to achieve root, custom kernels, costume firmware and then hacks and tweaks.

Those are the 5 main groups, each linked to a separate thread/topic that will help guide you through the process and hopefully avoid any problems. If you do develop a problem, please look through the topic or thread that you are in to quickly solve your issue. Also be sure to check the FAQ as your answer may already be there waiting for you.
