We appreciate the extra time you spend looking and posting in the correct forum so that others may be able to quickly find what they need and not have to dig through useless threads/posts.

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.

How to Easily Root your device.

How to Flash Custom Binaries Without Ever Incrementing the Flash Counter!!

How to Prepare Your Phone to Return to the Store or for Warranty Replacement. Or how to set your Back To Stock.

How to flash a custom Firmware/ROM on your Phone.

How to manually replace modded/stock system files.

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.
