I'm trying to downgrade my console, but I'm having issues with QA toggle and rebug toolbox. Every time I load it and try the button combination, it doesn't work. I tried using rebug toolbox to enable QA but it says not available. after trying multiple times I just went to system update and I noticed I was able to update to rebug 4.84.2. Will this brick my console if I proceed without getting the QA settings
