Problem updating H9 5.4.1 to 5.8.5 and i get a “bad” message on the unit.  i’ve tried bluetooth from 2 different devices and usb straight to mac.  I read that if the unit takes 10 seconds to power up there are alternative directions to install update.  Can anybody help?

Could you try updating your H9 using the Direct Updater via USB? I's bundled with the H9 Control app. You can find it in H9 Control by clicking "Window" -> "Open Direct Updater" in the menu bar. Note that you would need to power on the H9 with HOTKNOB pressed to boot into the UPDATE mode to do the update.
