Cannot unlock Windows Phone 8.1 for debuging and testing. RRS feed

  • Question

  • Today I have tried to unlock my Windows Phone 8.1 for debugging and testing Windows phone apps. After successfull login it failed with error "Error logging into the Windows Phone Dev Center. Please check your Microsoft Account and password and try again."

    I have tried Windows Phone Developer Registration and Windows Phone Developer Registration 8.1 and both failed with similar error. I have tried 2 different Microsoft Accounts and both failed. How to unlock phone?
