Sorry that you're having trouble updating your H9. It seems that for some reason the updated firmware is corrupted. Try powering up while pressing and holding the hotswitch button. This will put the unit in a manual update mode. Cycle power once more (without holding down the button) and the H9 should revert to the last firmware. At that point you can try updating once again.
