It sounds like the product has been bricked.  This is similar to what can happen if a router's firmware is being updated and there is a lost of internet or power.  Typically this is not something that is covered by the limited waranty as its not a manufacture defect or something we have control over.  Though you can email kasa.support@tp-link.com explain the situation and see if they can provide an exception.
