Deploying a windows phone app to an actual device does not work but still working with emulators. Error DEP6500 and DEP6100

Question

I tried several times to deploy my app to a Windows Phone device using Visual Studio Enterprise 2015 and that doesn't work and gives me an error message: " DEP6500 : A specified communication resource(port) is already in use by another application" , but it works well with emulators! why? also I have done the following to make deploying to a device works well, but unfortunately without a result:

• Trying two versions of Visual Studio, Ultimate 2013 Update 4 and Enterprise 2015
• Restarting the service "Windows Phone IP over USB Transport" (IpOverUsbSvc)
• Resetting my windows phone device
• Plugging the device in different USB ports
• Trying different projects types: Windows Phone Silverlight apps and WinRT apps
• Restoring defaults in Windows Firewall
• Signing out the current user account, and signing in to another user account, and then running VS and deploying a new app to the device, and I got another error message different to the latter message: " DEP6100 : The following unexpected error occurred during bootstrapping stage 'Getting endpoint address' "

What is this problem that prevents deploying apps to an actual Windows Phone device?

Answer 1

When connect the phone to PC, close every program that pop up, so it won't use the port, then check for the following

• Can you access your files and folder inside the phone on Windows Explorer?
• Does the charging icon on the phone show up, and the phone start charging?

These things maybe unstable, which indicate that your USB Cable is broken, change to a new USB Cable and check again.

Some other things to try

• Connect to a different PC
• Use a different phone to connect to the same PC and the different one (the best case is you already know it's working)

Answer 2

If you are using windows phone 8 for testing then update your phone to windows phone 8.1

Or

Use Visual studio 2012..
