LG Optimus L9 (LG-P769) Android 4.1.2 Build JZO54K Version P76920h Computer is not seeing phone at all (not even in Device Manager). I do not have original cable as it was chewed up by my dog. I have used about 10 different cables because I had to constantly replace them when she was a puppy and I have never had a connection problem before. In addition, I have used this cable to connect to the computer before successfully, as far as I know. I downloaded and installed the Windows MTP patch with no luck. Phone is not accessible via Bluetooth either. USBDeview doesn't recognize it as an active device and won't allow me to activate it, but it is seen there. Not entirely sure what to do at this point.
