Hi, I have a samsung europa, i cant find the usb settings anywhere in my settings folder to change over to pc studio setting. I cant connect to NPS coz the only opitions i have when plugged into laptop is kies and memory card. It wont update firmware through kies as it keeps saying cannot complete unknown error, so im trying to do it through NPS. All drivers are installed. Is there a solution or do i need to bring my phone back to store. Thanks for your help. Fixed: It turned out to be the handset so i got a replacement phone and now im running 2.2 froyo.
