Note: This will describe the process that a university student has to go through to unlock his device!

Meet, the process:

  • Download Windows Phone 7.1 SDK (or newer version) in App Hub and install
  • Create a Windows Live account (if you don’t have one already)
  • Go to and sign in with your Windows Live account
  • Get Verified by choosing your university
  • Go to and sign in
  • Click in one of those “Submit for [platform]” images.
  • You will be asked to activate your developer account, fill in the necessary information
  • If your get an “Error occured” message, try this!
  • When you have successfully activated your account in App Hub and after you have installed WP7.1 SDK, go to Start>All Programs> Windows Phone SDK 7.1>Windows Phone Developer Registration
  • Or you can execute C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.1\Tools\Phone Registration\PhoneReg.exe
  • Follow the instructions and congratulations, your phone is unlocked, go to Visual Studio and run your apps in your newly unlocked device! 😀
