Why is it impossible to regrade to newer firmware with Caltool ?? Still have to read the file out with Descprow and use maptrans..

It is possible with later versions of code, about 11-20 onwards but you need to have the regrade files to associate which are usually done through distributors/dealers.  

cheers.

I have found you can regrade from 11.16 (SQ6) onwards, but you also have to do each update inbetween, so you can't go from 11.16 straight to 11.23, you have to go to 11.20 first, then to 11.23.

The regrade tool should allow for this, so you should not need every metafile, BUT as I understand there is a bit of a glitch in one version before 11.20 or so and the update stalls.. I would say 11.20 up is more stable.
