I wanted to update my Nokia N810 at home this weekend dunno why I suppose its one of those things you just do. Anyway I plugged in the USB cable pressed the swap button and powered on, up came the little USB logo which should me youre good to go.
On to the PC and started the Nokia update software, Cannot find device huh? Unplug the USB cable and the Nokias Maemo software boots now heres the interesting bit plug the cable back in and the PC sees it?
I must have tried six or seven times but gave up so I brought all the cables and stuff to work, downloaded the updater software, installed on my works PC plugged in the cable pressed the swap key and the power key. USB logo, start the updater software Bingo! Worked first time so whats all that about then?
The only thing I can think is that something on my machine at home is blocking the N810 the only downside now is I have to re-install all the applications that the update nukes! Of course I had a backup but thats just for settings ect I dont believe it backs up the actual applications.
