Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
What is the exact model of your phone ? Are you using a Mac or Windows PC ?
That is a model of battery. I need to know the model of phone. Turn off the phone and turn it on and do you see the model number under LG logo?
Is this a full keyboard slide phone ?
It is probably the model Octane VN530
I will try to find the software for it and let you know.
Inorder to use the phone with your PC, you have to install couple of applications like USB drives and PC Suite.
Download and install the USB drivers from here --> http://18d5a.wpc.azureedge.net/8018D5A/tool/dn/downloader.dev?fileKey=UW00520120427
After installing the drivers, download and install the LG PC Suite from here --> http://18d5a.wpc.azureedge.net/8018D5A/tool/dn/downloader.dev?fileKey=PW00720110909
After installing the above two application, open the LG PC Suite application and connect your phone. Does it recognize your phone ?
Also open This PC and do you see your phone there ?
