Hello. I'm trying to update an 8.1 O3DS sysNAND to 9.2, and I saw that you succeeded at doing this using rxTool to swap in firm0/1.bins. It seemed like you would post more on it, but I couldn't find a follow up.
Would you mind posting your findings or maybe a tutorial on how to safely recreate your results? You might be one of the only people who really knows how.
And thanks for all your work!
