The things you will need:
Kin Two or Kin TwoM(I have not been able to test this on a Kin One or OneM)
A micro usb data cable
Drivers for the Kin available below
Don't worry about fixing the error in the qcser.inf, since I have already done this for you.
I would like to thank jennydevil for reminding us that these drivers are for 32-bit not 64-bit operating systems.
On your kin device go to the phone application. Once there dial ##77647266488 and call. It will ask you for your Service Programming Code. The default code is 000000. You will now be in a menu labeled "SETTINGS". Navigate to OTHER and then swipe to the left. Here you will see PPro, USB Pass-Through, and USB VID Stream. All of these options will be off. You will want to turn USB Pass-Through on.
Now connect your phone to your Windows PC. Your pc will try to find a driver called "Pink CDMA diagnostics" and will fail. Fear not. Open the start menu and right click on Computer then Manage. On the menu to the far left click device manager. In other devices you will see the Pink CDMA diagnostics. Right click it and press "Update Driver Software". Click "Browse My Computer for Driver Software". Browse for the location of the drivers downloaded earlier and click next. It will show a warning that the drivers are not signed. Continue anyways.
Now you are ready to open up bitpim. Set it to the same COM as the phone and make sure in the View menu that View Filesystem is checked. Now feel free to browse through the file system of your kin.
If you run in to any problems feel free to ask questions. If you have any ideas or information to make this tutorial more useful feel free to speak your mind.
