Enable Developer Mode (USB Debugging)
You may need to enable “Developer Mode”, for example, to transfer files between your device and your PC. To enable this mode:
- Go to the Settings App
- Scroll down to and click on About Phone
- Find the item Build Number and click it 7 times. Developer mode will now be enabled.
- Go back one level in the Menu (Back button left of the scan button on the hard- keyboard)
- You will now see an option that says Developer Options.
The most common option in the developer menu you may need to use is to enable “USB Debugging”. This is often required to allow you to do file transfers
If your PC still does not recognize the device, you may also need to enable USB Tethering. On the device:
Settings->More->Tethering & Portable Hotspot-> USB Tethering.
