Updated. After 1 upgrade and 2 hard reset I am done with that shyt. Rolled back to 8.1, couldn't be happier even I loss all my media contents on the SD and I have to redo my home screen.
I was so pissed at the w10m exp that if I have a way to write to Satya I will.
Indeed this is false information.
They would never put out a software without the firmware on their servers.
Here is the proof. Rollback to 8.1 is still possible.
Things may change once the firmware is ready as they might replace with the Windows 10 ROM
Yet the 640 XL has an official Windows 10 Mobile release, just because it may not be available yet in your region doesn't make my statement any less correct.
If your device has an official, non preview, release of W10M then you cannot roll back to WP8.1, the firmware and the OS are not the same thing.
OP specifically asked for a device which was in 8.1 and then got upgraded to W10M.
Some phones come with W10M out of the box. Those are the phones that won't be able to rollback to W8.1 (Because they don't have 8.1 ROM).
By saying that

You are clearly saying that the 8.1 devices which got the official (non-insider) W10M update won't be able to rollback.
The servers still don't have the full W10M ROM complete with the updated firmware for devices that were in W8.1.

Just so you know, my 640 XL is on W10M via upgrade advisor.

My device was on non inisder / non preview release when I checked with WDRT.
And I am very well aware that firmware and OS are not the same thing.
8.1 is still available on servers on WDRT. Those who want to rollback can do it.
When the complete W10M ROM (OS+firmware) is out on the server, then you wont be able to roll back to 8.1
W10M is only an OS update now without the firmware part. That is why there is no W10M ROM on the server yet.
Whereas the 8.1 OS ROM is complete with firmware.
