Hey, i have a galaxy s3 and i don't know how to update it from 4.1.1to 4.1.2. I tried wireless update from the phone but it says that the phone status is modified and therefore i can't update it. I downloaded kies but it says "Your device's current firmware version is not supported to update firmware via Kies". How can I change the device status to normal / make updating from kies work? Thanks in advance.
