I'm with orange/EE

there is no ota update so I've installed kies and do everything that's instructed

when i connect the phone it tells me there is a firmware update available.

I follow all the steps but as soon as the green man appears on my phone i get a pop up message on my desktop saying usb device not recognized, or words to the affect

this happens on my Windows 7 & XP machines

can anyone help? i'm ready to pull my hair out!!
