My H2S won't boot up at all since I updated the software on the unit. The initial boot screen (SKY skin) appears for a few seconds & then the screen crashes & an error file is displayed temporarily before the system attempts to reboot. The cycles of Boot up & error/crash then continues until I power the unit down via the mains button, as the unit is now unresponsive to the remote control too. Any assistance/advice would be greatly appreciated? Cheers.
