Somebody in the thread at some point said:

One nice thing to try, the U-Boot packages have been way out of date
(and still may be).  If you can struggle to get into U-Boot and DFU in a
new U-Boot when they are actually coming from our git, it could improve
your situation due to some months of our patches you don't have right now.

I looked at

and they still seem to use the svn / git naming convention which is
wrong, I guess they are not updated yet.

If it doesn't help, it sounds a bit like you don't have a VB_SYS cap on
there or something else is up.
