Conclusions
1) Never trust a firmware-image
from a different OEM model, even if it
looks exactly as yours! You might have
a different hardware revision, or the
OEM producers might have implement-
ed some kind of firmware-check, that
prevents cross flashing. The reason is
of course the different level of support
that each brand invests in its devices.
2) Before flashing a device, make
sure that you have a plan B, if things
go wrong. Normally, boot loaders do
provide a way to flash the firmware,
even if your device is dead (unless you
managed to delete the boot loader,
too).
3) You are totally at ease, if you own
an external programmer, which sup-
ports your flash chip. My cheap pro-
grammer has proven to be very good
value for money. It is impressive how
such a cheap programmer manages to
support that many devices. Another
thumbs up for this device, because
it works even if you just solder some
wires to the pins of your chip, instead
of using a proper adapter. Professional

programmers would not work in such
way, requiring for each chip package
the correct adapter (and such adapt-
ers cost more than my cheap program-
mer).
After this adventure, I can say that
I am much more fond of my satellite
meter and I have a deep respect on
how miniaturized it is. It is a pretty
good meter for standard installations
and for amateur enthusiasts of satel-
lite reception. Not being able to use it
for two weeks made me realize how
much I depended on it. So I promised
myself to not flash it with any firmware
again…
