It could be due to an unforseen situation not considered by the designers.
Several years ago a friend of mine bricked at CAR (BMW I believe---it was a
high end German car in any case). He was updating the firmware on the car
when the power cut out, leaving the firmware in an inconsistent state. The
fix required an engineer from Germany to fly to the US ...

True. But any designer who implements firmware update without considering the
possibility of power failure is not qualified for the job.
That was my reaction too. Are people seriously saying that even in
normal circumstances, you can brick the device? The most typical failure
mode being if you get a power interruption while flashing new firmware.
If the designers seriously did not take that scenario into
consideration, then we have a more broken design than I would allow for.
And to respond to the people who said I should re-read the original post
where it was stated that it was bricked... Here is the original text,
and there is no mention of bricking.
"...The manufacturer of the fake BeeProgs stole our logo and
intellectual property by manufacturing fake copies of BeeProg
programmer. This "product" uses also our software and users of this fake
BeeProg are asking for our free technical support. Although the copy of
the BeeProg programmer is done well, the manufactures of the fake
BeeProg overlooked few details. Result is, the fake BeeProg unit differs
from the original, visible for the software. We've
used one of these
differences - it is not a serial number - and our software could
detect
this fake hardware. If PG4UW software detects a fake hardware, it shows
message "Fake programmer unit detected!" and programmer will no longer work.
If you're facing such situation, contact please the vendor, where from
you bought the programmer, for full credit return. Or you can take this
vendor to court for selling a fake products. We regret, we could not
provide any assistance in this case..."
Note that the text says "it shows message ''...'' and programmer will
no
longer work."
That by no means means that it is actually bricked. It merely says that
the firmware will not continue past that point.
Now, if someone actually have one of these devices, and can verify that
it actually bricks it, then we can talk. Until then, all I have is the
above information from Elnec, which do not suggest anything beyond
showing a message, and not continuing past that point.
If the manufacturer of the device have not made allowance to recover
from a bad firmware installation, then there is a
problem. But that is
not necessarily something you can blame Elnec for either...
