I don't understand fully the description on the rebug site: I assume the result of running this is a downgrade to Rebug 3.55.4 REX, correct? It says it "Set's your SYSCON COREOS version to 9.99". Is this permanent or only during the downgrade? Also "Requires System Dehasing After Downgrade" Is this something I need to initiate? How do I do this if not automatic?
