[How TO] Enable Developer Options/USB Debugging
There are different ways to enable USB Debugging depending on the Android version installed on your device. USB Debugging is required by adb, which is used for rooting, backing up, installing a custom ROM from computer and more.
1. Android 2.0-2.3.x
Settings > Applications > Development > USB Debugging.
2. Android 3.0- 4.1.x

In Android 4.2 and higher versions, the Developer Options menu and USB Debugging option have been hidden. In former 4.X versions of Android, USB Debugging option is under Developer Options menu.
First, you need to enable "Developer Options Menu".
- Click Menu button to enter into App drawer.
