HTC EVO 4G :: New Rooting Procedure Explained

Some of you may be intimidated by the new 2.2 rooting instructions. Here's an explanation of what the steps do and why you're doing them. Hopefully, armed with this info, you'll be more confident in proceeding with rooting your phone. See this thread for reference: xda-developers - View Single Post - [GUIDE] How to root Android 2.2 on the EVO 4G

Steps 1-3:
In order to execute the root exploit, you need a tool called "adb." This stands for Android Debugging Bridge, and it is bundled with the Android SDK. The SDK is a package that allows you to write applications for Android, but the only reason we're downloading the SDK is for the adb tool, which is located in a /Tools subfolder in the SDK. The latest HTC Sync is needed because it contains the drivers that allow adb to interface between your PC and your phone. I believe the version of Sync specified will work with windows 7 64-bit. Mac users, scroll down to post 18 in this thread. EarlyMon has the procedure for you.

Step 4:
You need to turn on USB debugging on your phone in order for adb to work. You will be using adb to copy files to your phone and execute linux commands. More on this later.

Step 5:
It is important that your phone is in charge only. If it is in disk drive mode, your phone pretty much locks your sdcard from being written by adb. Make sure you're in charge mode.

Step 6:
Now you have to copy files onto your phone via adb. The "adb push" command basically takes a file on your PC and pushes it to your phone. If you needed a file copied off your phone onto your PC, you'd use adb pull. Easy, right? Let's look at the first copy command:
