I've also tried RumRunner, and have had no success.
I'm not sure what ADB and Fastboot are, but I think I have some ADB stuff installed on my comp [ C:\Program Files (x86)\Minimal ADB and Fastboot ] and I have that path in my Environment Variables>path directory. I don't know what to do with it.
Please help me get started. Step by step instructions would be great. I saw a thread that isn't very old where someone was having root trouble w/ KitKat but they were able to run Firewater. I need help getting that started at least. Thank you.
Edit: Fastboot is Off
USB Debugging Enabled
HTC Sync (can't find it anywhere on my comp, or in the programs list ((control panel)) so I assume its not installed)
Drivers are installed on my comp.
