[One (M9) Q&A, Help & Troubleshooting] Flippy498:
I'll take a closer look at the RUU. Unfortunately, my download speed seems to be insanely slow, today. I probably won't be able to reply until tomorrow.

Edit: I can't replicate the issue with the wrong version number using this RUU and this version of the decryption tool.
