Got mine from Woot Friday, (it didnt have too far to travel) i have been trying for days w/o sucess to update to ermine, got it done finally by :
1)changing usb stick to Fat not fat32, (done by formatting usb)
2)also changed properties of file to opens with adobe pdf (right click look at properties)
3)also named it 'update' not update.zip.zip (will still be update.zip in properties)
4) i held down those 2 keys until i saw the updating screen. (longer than 10 secs)
i am not the most computer literate person but I dont consider myself to be helpless...
anyway hope this helps any wooters who will be on here trying to figure this out after they get theirs in the mail soon, good luck I am off to hook mine up with my local library now
