I would like to flash a generic flash file to my W760 but I am little bit confused on the step of customizing the phone. In A2 Uploader, the insturction says to copy the custom files in to /tpa/preset/custom in your phone. Can anyone please explain how do I copy the custom file into the phone. I don't want to brick this phone so I would like to make sure I know exactly what I am doing.

Any help is appreciated.
