Yikes! How does that happen? Has the ROM been unsoldered/resoldered?

Not sure how it happened. ROM was not previously removed and the user is your vintage, without any tech knowledge. I'm wondering if they somehow tried to flash the ROM via the DLink NAS (no idea how they would do that) without success. No matter the cause, it is absolutely empty, unless you are a half-full kind of guy in which case it is absolutely full with 0xFFFF.
