Nexus 4: Google’s latest Nexus smartphone or let’s say “The phone of the era”. This marvel shall beat all others standing against it with its 15 GHz Quad-Core Krait processor and 2GB RAM and also yet other massive features that would clean its way.

When I’m in Bootloader mode – with the Start green arrow as shown in your above screenshot – on my laptop I issue : fastboot erase boot I just get message : waiting for device
It indicates that you do not have fastboot interface correctly setup for your device.
