did you patch the navboot file?
did you add a phrase to #8 or #9?
did you test the phrase before loading?
did you add 0507 voices instead of 0506?
did you update the voice sw_rel table?
was the 3 x GB intentional or not?

Of course you don't need to edit the 1000 string when rolling back to V32, because that's the version info. V32 contains version 10.00 (1000), and you should not change that.
