I have to update my Kindle Version 4.1.3. I have tried to do it via wi-fi (this connection works very well to down load new books and synchronise) but it doesn't work.
I want to do it manually now, but even if I connect my kindle -with the usb cable- to the laptop no kindle drives appears on my desktop. Help!
kindle has to be turned on and password/pincode input before connecting the usb cable/cord
