Hi, it's the first time for me using this software and it's not working. I might be doing something wrong. I have a non-rooted xperia sp with locked bootloader.

This is the result after installin driver, updating java, enabling debugging mode in my case:

Please connect your Android device with USB Debugging enabled:

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
