You can use the Lumia Software Recovery Tool to reinstall the OS

No you can't. Software Recovery Tool does not see a device in this state and returns an "incompatible model" error code.

You need to do a hard reset using the physical buttons on the phone to reflash the OS from system memory. Nokia Lumia 520 hard reset
