Any Android user who is fond of rooting their devices must have come across the term USB Debugging.
According to Wikipedia;
I’ve always switched USB Debugging option to ON in all of my devices since they are rooted and anything can happen at anytime.
This feature enables you to connect your android device to a PC using programs such as SDK which comprises of ADB and Fastboot.
Debugging is mostly used by developers who find it easier sending commands using a computer to android but that does not mean an average android user like you cannot take advantage of this time-saving feature.
Depending on your android version,this option differs with each versions of android.
Go to settings=>Applications=>Development=>USB Debugging (Tick to enable).
(Honey comb,Ice cream,Sandwitch,Jelly Bean)
Go to settings =>About phone=>Developer option(Switch on)=>USB Debugging (Switch on)
Go to settings=>About phone=>Build no(Tap on it seven times to enable USB Debugging)
once you see a message that “You are now a Developer”,go back and tap on Developer options just above About phone and enable the option of Debugging.
Similar procecure as ANDROID 4.2X and above is followed.
Now that you know how to do it,try using a procedure designated to enabling this option on your device and let me know if non of the above methods worked for you by leaving me a comment.
