Galaxy S II GT-I9100G USB connectivity problem I bought a Galaxy S II GT-I9100G two weeks back from Malaysia and it was running on Android ver. 2.3.5. But three days back I saw a 2.3.6 update available and updated my phone using the update option available in the phone. But now when I connect phone to PC via USB it shows unknown device and Windows cant find the driver suitable for it. And so I can't transfer files to or from my PC. Could anyone please help me out here?

My PC is running on Win7 x64.
Worked for me:


Unplug the USB cable
On the cell phone, dial the following number: *#7284# Once the last # is hit, the PhoneUtil application is launched. Choose USB -> Modem and then USB -> PDA mode. The good mode should be PDA. Even if the mode is PDA, switch to Modem and then back to PDA.
Plug the USB cable.


Note:


Repair USB connection for any Samsung Android phone
