The first thing to try is the C771 Drivers From Phone, located in Commando->Drivers->C771 Drivers from phone. Download, extract, run. If that does not work, then follow the directions on this to directly install the drivers.
Download the "direct Install" Drivers. OneDrive->Commando->Drivers->C771 Drivers Direct Install. They are the drivers for the phone, but extracted into their .inf and .sys forms. These can be installed via the find new hardware wizard in windows.
Plug in your phone, and make sure it is on charge only mode.
Open Device manager (in control panel) and right click on the device. It could be "C771" or "Unknown Device". with a question mark. Right Click and click update drivers.
Click "Browse my computer for software"
explain manual driver install.
click browse and bring it to where you have stored the drivers. click next or OK.
Let them Install
Repeat for any other yellow question mark devices.
Done
I would love some feedback to verify that it works.
