There is no way to get the data saved, because you need to expand the calculator tree in the CK to reveal the Backup option, and that is when the calculator crashes, right?

With a firmware downgrade there is some chance that "maybe" user data is retained? I thought that was the case but someone else may know for sure. At least the CK allows for a firmware installation without expanding the calculator tree.
