Samsung Galaxy S2 GT-I9100 ????? Trying to upgrade the software, but do not let the ''impossible'' SAMSUNG upgrade. I Install KIES software and it turns to s..t. Do not install the drivers correctly. Some random driver. Can not find Device. Is it possible to backup files to a different program and update the software? Is there any solution? I am so as to allow the air to Samsung. The KIES does not fit anywhere.
