My ZP90 keeps flashing white and does not show up in S1 anymore. I had run an update which completed downloading to the unit but got stuck at unit "restart" with light flashing white for a few days. I tried plugging off and on and tried reset by holding the mute button but light just keeps flashing as soon as I plug in power. Is there anything else I should do? Thanks!
