My U.S. Cellular S3 has recently been restarting by itself on random moments. I've read online that I should restore the factory settings, so I've been trying to use Windows' Kies to backup my files, but it hasn't been recognizing my device. I tried re-installing the software twice now, and the only thing that realizes I have a phone plugged in is my computer itself. I also heard that Kies does not support U.S. Cellular phones, so maybe that is the problem? Does anyone have suggestions on how to fix Kies? Or any other FREE backup/restoring softwares for Windows? Also, do the workers at U.S. Cellular have backup/restoring programs that I could just have them help?
