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.
