I hesitate to add a device that solely depends on an OEM firmware exploit.
Apart from that, just referring to some (non-OEM) external tool is quite
inconvenient. If the page is deleted tomorrow, we won't know how to flash
anymore.
So, I'd be happy about some alternate method and/or some details to reconstruct
what the external tool does.
