Step Two: Download and install HTC Drivers
Step Three: Download Revolutionary: S-OFF & Recovery Tool (Note the download link is at the bottom of the page. You will need to enter your EVO’s Serial number which is located under the battery. Make sure you to copy/write down the beta key. You will need it later)
Step Four: Enable USB debugging mode & fastboot on phone (To enable USB debugging go to Setting – Applications – Development – check box for USB debugging) (To enable fastboot go to Setting – Power – check box for Fast Boot)
Step Five: Connect you phone to you PC - Select USB Charging
Step Six: Unzip Revolutionary tool and run it as admin (to run as admin, right click and select run as admin) (make sure you install recovery image when asked) (Note after the tool is complete you may be left in fastboot mode, this may happen if recovery doesn't flash or something goes wrong with flashing the recovery. If this happens just select bootloader then select recovery to see if you are able to boot into recovery. If you are not able to boot into recovery or it hangs try flashing AmonRA Recovery from bootloader.)
Step Seven: Boot into recovery
Step Eight: Flash SuperUser and reboot your device.
Q: When I run Revolutionary tool it just sits at "waiting for device".
A: Make sure you have HTC SYNC Closed and or Removed in order for this to work - Thanks @smallba
Q: I'm stuck at "zerging root" nothing seems to work.
A: Again make sure you un-install HTC sync and turn off your antivirus and/or firewall
Q: I keep getting invalid key. What am i doing wrong?
A: The beta key is case sensitive so make sure you get it right, try to copying the key into notepad to verify the characters. The Revolutionary tool will give you your device serial number, verify you entered the correct SN. If you are still having issues try regenerating the beta key. If all fails try re-downloading the tool.
Q: I'm having issues flashing anything from recovery.
A: If you are having issues flashing/loading new roms try updating ClockworkMod Recovery from market via rom manger or flash AmonRA that seems to fix it
Q: How do I flash AmonRa Recovery in bootloader mode.
A: Download AmonRa Recovery PC36IMG.zip to the root of your sd card. Boot the phone into the bootloader by powering the phone down, then press the power and the volume down buttons at the same time.Once the phone boots into the bootloader the phone will automatically recognize the zip file. It will ask if you would like to update, select yes and let it do it's thing and you will be good to go.
Q: Will this wipe my device?
A: No if you follow all the steps this will get you S-OFF, Custom recovery & Root.
