Okay so I'm sure you've all heard it before. I was trying to wipe my recently acquired Nexus 5 (from Ebay) which had already been rooted. In the standard recovery mode, some how in my idiocy, i delete the entire OS .... i have tried to flash the latest available version of hammerhead but it keeps failing, i gather due to having no boot.sig or system.img already on the device.
All help appreciated very much as i hope to resolve this ASAP.
Many thanks in advanced for your time and know-how,
