RE: V84.0.140, downgrade no longer possible?
You obviously read correctly, the release notes say:
Quote:Optimized the upgrade mechanism. You are not allowed to downgrade the phone from current firmware to the previous one.
You will probably not get an answer as to why it was needed.

The only way to downgrade, I assume, would be with a TFTP recovery flash.
