That is strange as the FAQ for this upgrade states…
"
Wait a sec, this has to come back to you for upgrade? This isn't fair! I don't live in the USA!"
…"Due to the need for firmware and hardware updates, this upgrade must be done by Schiit, or by an authorized service center such as Electromod in the UK. Because of this, there is no self-install option, sorry. Yggdrasil Analog 1 cards will not be returned from this upgrade."

So I wonder how he got the firmware chip in the first place since I see no means of having them send one to anyone.
AND swapping out chips is, shall we say far more problematic for the average user, than a card swap and for a variety of reasons, (ESD, pin orientation, manual dexterity and ALL of the added customer frustration when things go sideways).
Just say'n…
