Im having problems updating my samsung galaxy s to firmware 2.2. Im trying to do it trough Samsung Kies but when I connect my phone, there is no connection recognized in Kies, however my phone says 'connected trough usb' (and it charges and everything). In windows (divices and printers) there is no icon for the phone. When I connect the phone, I hear no 'divice connect beep'. When I try to install the usb drivers seperatly, I get a 'unknown device not installed correctly' error. I tried it on a pc with win xp and on one with windows 7. Tried reinstalling and everything. Is there any way to fix this problem? Is there any alternative way of updating the firmware?
