"B&W Zeppelin Air - LED flashing White - Firmware recovery failed"に関する回答Mine shows also that I should finish FW upgrade. FW upgrade made, nothing changed, just steady white light. (Bowers&WilkinsControl_1.2.4_14587.zip, can be downloaded from Official BW site, search for it, no permalink, and version may change) It seems to be that I got the PU EL-CO fault too, after opening the coverage. They are domed, as mentioned. See pictures attached. Will post again when Fixed.
