Third-party confirmation for Beosound 2 (mk.1): The PDF instructions above and its embedded links to firmware, were reported to successfully resurrect a Beosound 2 mk.1 which had lost its S/N and Type, on Beotalk podcast #270.
@mikipedia reported the symptoms of the failure were “everything worked except the App,” i.e. the internal webserver, Airplay response, Bluetooth playback, and connection to Wi-Fi, all functioned as originally designed, just the App could not “see” the unit to add it. The failure occurred after the unit was factory-reset because it would be newly added to an account & a Wi-Fi network.
@Beowillie reported being unable to find this info doing searches in BeoWise. He speculated that the loss of serial number, which does not happen often, but apparently often enough to warrant the repair notes, was the result of a CMOS NVRAM battery discharging after the unit being left unplugged. (Apparently in @mikipedia’s case that was ~2 years?) But he could not account for such cause, because battery failure should have affected many, many units, including those which may have languished on the shelf at dealerships before sale.
