Press Menu > Settings > Connectivity > USB connection mode
Connect your phone to your computer using the USB cable. Choose Data service and synchronize your phone using the LG PC Suite software to copy files from your phone. If you have a memory card inserted, select Mass storage to use your phone in the same way as you would use a USB stick. Connect to your computer and drag and drop files to the GB250g removable device folder.
Note: To use the USB mass storage function, you will need to insert an external memory card in your phone.
