The Omnia ONE has two built-in software banks. When a software update is performed, the new software is loaded into the bank that is currently not in use. By loading a different style (downloadable free from OmniaAudio.com/software) into a software bank and then booting the unit from that bank, the unit will be running the new style. In fact, this procedure is exactly the same as for a software upgrade. Please see the Omnia ONE user manual for full instructions.
Via front panel or Ethernet remote (built-in web page) : "omnia"
This is likely to be a hardware problem that will require a trip in for repair. It can be the result of the unit having been exposed to a power surge or lightning strike. Please contact Omnia Support to schedule a repair.
Download and install the appropriate V2.8 firmware for your Omnia One. Version 2.8 provides a separate application to run your remote, and no longer depends on native Java compatibility in the browser.
