Hi All, My Lumia 640 xl having insider latest build 14393 version and now I want to go for production/public release which is much stable. I have tried using WDRT but it shows lumia 8.1 denim as available software. Can someone let me know how to flash windows 10 mobile os using PC to lumia 640 xl?

You can\’t. Only native Windows 10 Mobile devices can flash that way. You should be able to go into Settings->Update and security->Windows Insider Program. On that page, you should be able to change to Production.
