We have a Samung Galaxy S3. We did not know that this had been rooted (we think) and it is running Cyanogenmod. We do not like this and want to get it back to the original Samung OS (i.e. android!). We are not mobile phone techies so want a simple easy solution. We have heard about doing a factory reset (power off, connect to power supply and press volume up + power then scroll through menu and select factory reset). Can anyone tell us if this will reinstate the phone to its original software state (i.e as it would have been purchased) and get rid of cyanogenmod. Any help would be gratefully received. Many thanks
