How to Install Latest Windows 10 Builds on Unsupported Mobile Devices

Initially the Windows Insider Developer Preview was available for all the Windows devices, but at the time of official release most of the old Lumia devices were dropped off the list with Microsoft stating that “Windows 10 delivers significant new innovations, and many older devices are not able to successfully upgrade without an impact on the customer experience. Our goal is to only offer the Windows 10 upgrade to devices that we are confident can continue to deliver a good customer experience”. After that day no Preview builds were released for the old Lumia devices. The last build which was released for those devices was 10.0.10586.338.

    • Saif September 5, 2016 at 12:02 pm #

      Microsoft has removed that build from the server for all the unsupported devices. 🙁
      You need to unlock bootloader and make the registry changes to get 10586. 🙁

    tried deploying custom pfd and got error- 0x01030120 and the manifest could not be loaded and may not be valid

    • Saif September 5, 2016 at 11:55 am #

      In the vREG app, go to Templates and check ‘Live Interop & Restore Ndtksvc’. Tap apply and stay on the same screen.
      And then deploy custom pfd app.
      If you still face the issue then reboot your device and try it again 🙂
