I have installed the latest USB drivers, and turned debug on in the S4
I get get adb to launch, but when I use the command "ADB devices" nothing shows up.
I have rebooted both PC and phone with the same results.
Does the phone need to be rooted before ADB will work? If so....then how to I side load "Towelroot"? or anything else for that matter.
am I missing some sdk files...or something else?
