The process works but the resulting image does hang when  trying to load Monticello-ar.323(321) - I saw 2 lists message referring to that bug and the answer was to rather use the latest trunk version from http://ftp.squeak.org/trunk/

I don't recall the issue in question. Can you remind what it was? The 
only thing I remember is that of having to change an iVar in 
MethodContext and the answer to this is to execute the following before 
you start updating:

	MethodContext instVarNames at: 2 put: 'closureOrNil'.

No, the goal is that people should always be able to build their own 
images from 3.10 or 3.10.2 or any derived variants.

Clear the Monticello caches, i.e., open the Monticello browser and 
choose "flush cached versions". This should help.
