Hi Neil, please don't ring my Mum, she haunts me enough as it is! Okay, I've renamed my rgn to 194801000821.rgn (SW version 8.2). I drop the rgn file into Updater, get the window. I can't get passed the message in post 9, even with 2 of us doing the procedure. I've tried 2 cables, front and back usb's, disabling anti-virus sw and talking nicely.
I tried your other method, but can't get the unit recognized.
