Once complete, you will see your account name listed on-screen. on “Add Existing”, and add your Microsoft account credentials. On the main Dev Mode dashboard, you will see a box on the right called “Test Accounts”.You can find it by navigating to Settings > General > Network Settings. Note that you will also need to be connected to your home network for the rest of this tutorial, so if you are not already connected (I recommend an ethernet connection if possible), then go into Settings and set up your network connection. Depending on your TV/monitor setup, a pop-up may ask you to enable advanced video features - go ahead and enable that.The first time you boot into Dev Mode it may take a while. As a heads up, any time you want to boot into developer mode you will want to open the Xbox Dev Mode app and reboot from the main Xbox interface.
Back on the Xbox, you will be prompted to switch to developer mode by restarting your device.If you’d like, you can add a device name for your Xbox at this time. Enter this code into your PC on the activation page and select “Submit”. Go through the prompts until it asks you to activate your account via a six-digit alphanumeric code. Open the Devkit Activation app, and it will greet you with a welcome page.
Note: if using an Xbox One console, it will be a different app just grab the app that has an icon that matches your device! It will have a green icon that says “Devkit Activation”.
