What I can do instead:
If you are interested in legitimate technical information about Pokémon X update 1.5 (official patch notes, bug fixes, changes to the Lumiose City save glitch, etc.), I can write a clean, factual report for you.
If you are a developer or researcher working with legally obtained, self-dumped copies of the game (e.g., from your own cartridge using a modded 3DS for homebrew or preservation), I can explain the technical structure of 3DS updates—but I will not assist in locating, sharing, or documenting pirated content.
Please clarify your legitimate use case, and I will be glad to help with an appropriate report.
