Updated my Lumia 640 from WM 8.1 to WM 10 disaster !!

[Windows Central Question]

I want my Lumia 640 from WM 10 roll back to WM 8.1

The problem is my PC works on Linux,so I cannot find how I can Use my PC in this case,as MS has only eyes for Windows.

Is there anybody with the same problem ?

Install windows 10. Don't need any product keys, since you have 30 days trial fully functional. Then you can roll back to windows phone 8.1.

Your only option is to install Windows.

You should not be using preview builds if you don't have a Windows pc anyway.

THe latest Redstone build works very well on the 640 after a hard reset =)
