On November 8th 2020 I began tweeting about a Lumia 950 XL supposedly running the OS the Microsoft Surface Hub runs:
You’ve probably been aware since a few months that I’m able to make FFU firmwares for Lumia devices that are flashable on retail unlocked devices without any issue. Some of you may have also noticed a tool I open sourced on github that enables you to exactly do this. However this tool was never meant for wide use since it’s not finished and requires special instructions to be used properly and safely for a device. This post is aimed to explain you how to use this tool.
First of all, Welcome to 2019, and happy new year everyone!
Edit: This post has been updated by Rafael Rivera because it was very rough, thank you!
Rene Lergner’s WPinternals tool supports Microsoft Lumia devices out of the box. But thanks to a newly surfaced production-signed EFI application, all the others – like the Alcatel Idol 4S, HP Elite x3, and HTC One M8 – can join the party too.
