Q1: Do I need Update 1.5 if I’m just playing single-player?

A: Not strictly, but it is highly recommended. The Lumiose City save glitch can corrupt a 60-hour save file. Update 1.5 is cheap insurance.

Q2: Can I install this update on a stock 3DS without CFW?

A: No. Stock firmware only installs signed CIAs from the eShop. Since the 3DS eShop is closed, you cannot legally obtain 1.5 without a hacked console or a friend who already has it.

Part 2: Why the CIA Format?

If you own a legitimate cartridge, updates typically download as .CIA files (CTR Importable Archive) directly from Nintendo’s CDN. However, the official eShop is now closed for 3DS purchases, and updates are no longer served to unmodified consoles. This is where the Pokémon X Update 1.5 CIA comes into play.

Warning – Legality:

Downloading a Pokémon X Update 1.5 CIA from a public ROM site is only legal if you own a legitimate copy of the base game and have dumped your own update files. We strongly encourage users to dump their own cartridges using GodMode9.
