We have a THOMSON DTI 550 freeview box on a TV that's mainly used by our children (to end the TiVo vs CBeebies arguments !)
I was watching it last night and while flicking through channels on QVC it popped up a dialog offering to upgrade SW (from 2.1 to 2.7 IIRC). Pressed OK to start this and went away as it said it would take 10mins and I didn't really need to watch someone on QVC explaining how a scanner worked! Came back after a bit to find FV box on "standby" (red LED not green on front) and totally non-responsive to the remote.
Anyone got any ideas if there's a way to reset or has it upgraded itself to brick mode?
