Hi all. I'm using this guide to root my HTC One. I have made it to step 4. The drivers installed correctly and show in my Device Manager window just fine. When I type this into my command prompt: adb backup -apk -all -f backup.ab it comes back with: 'adb' is not recognized as an internal or external command, operable program or batch file. Can someone help me out here? I love the One but this weird layout they have is driving me NUTS!
