I've tried to update my LinkStation to v1.73 firmware. After the LSUpdater transfers the files, the final boot never returns and eventually times out. I can put the unit into Emergency mode and see it through the NAS Navigator2 and I can re launch the LSUpdater and see it when it is in EM Mode. However booting it normally the unit has a steady blue flashing LED, but does not connect and is not visible to NAS Navigator2. Any ideas for diagnosing this further?
