HTC M8 Bricked totally w/o Bootloader,recovery, nothing

Dear all,

When i connect the phone to the Windows now - i see the following screen in explorer:


Here the plugIn in the windows device manager - do you know why there is marshall london as a name given?


Further the usb controller


and the mobile devices overview:
