WPI 2.4 unlocks it just fine. Flash it back to the latest 8.1 version.

EDIT: Or...It could be updated to a version of W10M that is supported like 15063.297 etc.

Hello, I have a question. Is it possible edit a xap, like the lumia camera, to try to activate the focus while shooting video?? I'm trying study some ways, and I have differents xaps decrypted of the lumia camera, but now I don't have any ideias. I have installed some app to see xap info and edit, but how find this option of camera? Nobody have tried it before?

Spec B phones cannot be unlocked with 8.1
i have 10586.107 right now which is supported by wpinternals but it need FFU files for unlocking.

Edit: Successfully unlocked with rm-1086 FFU file. just if someone stuck on that step.

Incorrect. It can actually unlock a spec B device with its native FW (8.1) or W10M updated.
However you are correct in that it needs supported FFUs to find the flashing profile. Download the appropriate ones.

Just an idea.

It will be amazing if you can do this as a dual-boot between this and the original Windows Phone OS. In this way we keep the mobile functionality of the Lumia phone when we need it, and when we don't we boot in Windows RT. Maybe you can work on this next. :fingers-crossed::fingers-crossed:

You just have to shrink the data partition and create a new one for RT instead of deleting mainos, data. It works fine.
