I made this because I found it hard to find instructions.
I DID NOT MAKE THIS ROOT!
Download this Zergrush Root (mirror'd on my server) and extract somewhere where you can find:
1. Connect your phone to your computer via USB. Turn USB debugging on.
2. Download/install HTC drivers if they aren't already installed:
3. select HTC Sync When you plug your phone in. Charge Only may work for others, but HTC Sync is the only one that worked for me. Let windows install the drivers if needed.
4. Navigate inside the folder you extracted and right click on ZergRushTempRoot (.bat), and click Run as administrator. Then follow directions.
