Deploying XAP using Windows Phone SDK/Mini SDK

• Firstly, make sure that you have a developer unlocked Windows Phone (7/8/8.1) device. If you don’t, follow this tutorial to unlock your phone. It’s free.
• Download the Windows Phone Mini SDK or the Full SDK as needed (download links in the above tutorial). However, if you have a developer unlocked phone, chances are that you already have it installed on your PC; so skip.
• Connect your Windows Phone Device to your PC using a Data Cable.
• Click on Start and type Application Deployment. Then launch the Application Deployment app.
• 
• 1. Set Target to Device.
  2. Click on Browse in front of the XAP field and locate your downloaded (cracked) or self-packed XAP file.
  3. Make sure your device’s screen is unlocked. Then click on Deploy at the bottom right of the window.
  4. After a few seconds, the application will show a XAP Deployment Complete status.
  5. The app has been deployed. You can now disconnect your phone and start using the deployed app.
