Unlike the base game, 3DS updates are often region-locked, even on CFW. If you have a European 3DS (Region F includes France, Germany, Spain, Italy, UK – but specifically “F” sometimes delineates French-language consoles), you need an update CIA that matches or is region-free.

For French players (Region F), using a standard “EUR” CIA is usually fine. But the explicit “Region F verified” label means a French-speaking tester confirmed the patch works on a French 3DS with French system language – no missing text, no online errors.

| Error | Likely Cause | Solution | |-------|--------------|----------| | Failed to install CIA (result code: 0xD8E0806A) | CIA region mismatch with console | Use a “World” or correct region CIA. | | Game still shows Ver. 1.0/1.1 after install | Update title ID does not match base game region | Uninstall update via FBI (Titles → find Pokémon X Update → Delete) and try a different region CIA. | | “An update is available” when launching | Update installed to wrong NAND (e.g., on EmuNAND vs SysNAND) | Install the update on the same NAND you use to play games (usually SysNAND for modern CFW). | | Black screen after Nintendo 3DS logo | Corrupted update or conflict with a mod (e.g., custom skin) | Boot into safe mode (hold L+R+A+Up on boot) and uninstall update via system settings → Data Management. |

Before you can install a CIA file, your Nintendo 3DS must be modified (Custom Firmware).

| Component | Title ID | Version Number | File size (approx) | |-----------|----------|----------------|---------------------| | Pokémon X (Base) | 0004000000054500 | v0 (original) | 1.7 GB (CIA) | | Pokémon X Update 1.5 | 0004000E00054500 | v3072 | 18–22 MB |

Important: Update CIA files are small (under 30 MB). If you find a “Pokémon X Update” that is over 100 MB, it’s likely a fake or a repack that includes the base game – treat with caution.

The “World CIA” version of the update typically contains the following system archives:
