I received the new V1.11 MDx Upgrade for my Bricasti M21 DAC. SIM card from Bricasti, As per the enclosed instructions, I have to power down my Bricasti M21 DAC, remove the cover, insert the firmware chip into the unit and turn the power on. The instructions say inserting the chip needs to be done very carefully since there are no pins to guide it.
The DAC will be updated using the instructions in chip. When the upgrade is completed, the chip can be removed. A message will be displayed saying the upgrade is complete.
The instructions also said that some units cannot be updated meaning they have to be returned to the factory. I plan on doing the upgrade Saturday afternoon.
