Hey there, I have an I9100G, bought it late: on 1st of may, and suddenly for the last couple of weeks, it is not being recognized nor accessed in ANY way! It was ok for like 3 weeks, then it just sopped! I get this message: failed to install Samsung Mobile MTP Device, and i can't even access it as a mass storage: no autoplay, nor even it appears on explorer as a drive (i use WinXP SP3). I have tried EVERYTHING! I completely swept Kies out, removed it from registry, all Samsung USB drivers, and all .dll's, reinstalled them 3 times now - > nothing Connection troubleshooter -> nothing Updated .NET Framework before one of the Kies reinstalls -> nothing Opened it with debug mode on, then when it's off (drivers in debug mode install fine, though) -> nothing Tried the UART/USB trick - > nothing. Can't execute the "18 characters long" files delete, as i can't access my mobile through USB in the first place. I am fed up, frustrated and tired! I would be very thankful if you helped me with this.
