I've been trying to update my Samsung Glaxy S2 X T989D via Kies (the normal version, not the lite one or air). However, it does not show the phone's current firmware version and therefore does not provide me with the "upgrade" button option. I've tried with the phone turned off and then on once is connected to the computer with the usb cable and Kies is running, but still it does not show the current firmware version and does not allow me to upgrade. Any suggestions? Thanks.
