I have today updated a few of my Powerboxes with success, but one Comp SRS failed when reaching 45%. It stood dead still for 10 minutes and I disconnected and reconnected but still the Rescue program failed to start. I restarted the computer, Terminal program several times.
The upgrade was from V2.7 to 2.8. Now there is no connection, the screen says only " No Powerbox-Device connected.
Any good tips will be well received.
