Entering Mass Storage Mode

To start, you will need to switch to Mass Storage Mode on your phone. Here are the steps needed in WPInternals:

Make sure any other tool is closed, then open WPInternals and plug your phone to your PC. You now have two options:

Option A) If you currently have booted into Windows Phone, go to the “Manual mode” tab and choose “Switch to Mass-Storage-mode”.

WPInternals page for mode selection

Option B) If you don’t have access to Windows Phone or if your phone is not detected, go to the “Manual mode” tab, and click “interrupt the boot-process”. Then do a soft reboot on your phone: Keep holding the volume – and power button at the same time until your phone shuts down and vibrates. WPInternals should now detect your phone, and you’ll be able to choose “Switch to Mass-Storage-mode” in the “Manual mode” tab.

WPInternals is looking for the phone

Wait until WPInternals reports that your phone is now in Mass Storage Mode. Now CLOSE WPInternals. It needs to be closed, or the next steps will fail for sure. This is important, so don’t leave it running.

Your interface will now display the wim file you've chosen. Next, go to the "Advanced" tab.

Here, choose if you want to Keep Windows 10 Mobile (so that you will be able to use Dual Boot later) or Overwrite it. Think about this now, as you will need to start from scratch if you change idea later.

Now let's go back to the "Deployment" tab, and when you feel ready, press the big "Deploy" button.

WoaDeployer is ready to deploy

Let it work and you will get to a page with the latest changelog. Read it! Then press "Close" to continue the installation.

WoaDeployer will keep downloading things and then start the installation all by itself. Let it work. You might see some notifications from Windows popping up about new devices being detected, ignore them.

At some point you will be prompted to switch again to Mass Storage Mode, this time using the Developer Menu that just got installed to your phone.

Read the screen, and follow the instructions as they're reported. If you follow the steps correctly, at the end you'll read "UEFI Mass Storage" and "Connected" on your phone screen.

Click "Continue" on WoaDeployer.
