Users who notice unfixed-info.bin often report the following issues—but note: these are not caused by the file itself. They are correlated because they occur during AMD driver updates:
Navigate to the settings menu and locate or Import Keys .
Before these apps can read a backup or write a new NTAG215 tag, they require the user to import unfixed-info.bin and locked-secret.bin . Without them, the apps cannot decrypt the character templates or sign the custom data packages. 2. Hardware Simulators (AmiiboLink, Pixl, and Flask)
Note: As of mid-2026, some older guides on Reddit (like r/LinksAmiiboArchive ) still provide valid repositories for setting up these keys, alongside updated Amiibo data dumps. Troubleshooting unfixed-info.bin unfixed-info.bin
: In TagMo or similar tools, use the "Load Keys" option to select both files.
Most apps look for this specific filename. It is best to keep it exactly as unfixed-info.bin to ensure the software recognizes it automatically.
This is the area of the chip where the console writes save data. It tracks your in-game levels, customized spirits, training progress, and daily rewards. Because this data constantly updates during gameplay, the cryptographic system must handle "unfixed" or shifting information—hence the name of the key file. How to Use unfixed-info.bin Users who notice unfixed-info
This includes read-only attributes like the character type, series, and unique identifier (UID). The cryptographic signature for this area is derived using the locked-secret.bin key.
| File Name | Purpose | Deals with... | | :--- | :--- | :--- | | | Contains the key for the static , permanent information of an Amiibo | The Amiibo's fixed identity, including character, series, and a unique identifier that never changes. | | locked-secret.bin | Contains the key for the dynamic , changeable information of an Amiibo | User-specific data that changes over time, such as experience points, nicknames, and game progression. |
The computing world still has unanswered questions about unfixed-info.bin : Without them, the apps cannot decrypt the character
If you are setting up an Amiibo utility and encounter errors, the solution usually comes down to file naming or structure. "Keys Not Found" or "Missing Cryptographic Keys"
: unfixed-info.bin is one of two "master keys" (the other being locked-secret.bin ) required to decrypt and encrypt Amiibo data.
In practice, most enthusiasts search for pre-extracted files online. Because the files are identical across all retail hardware, a single extraction works globally.
After digging through forums, GitHub issues, and even a few IRC logs (yes, people still use IRC), patterns emerge:
Modern hardware tools like the , AmiLoop , or AllMiibo use Bluetooth or small screens to emulate hundreds of different figures on a single physical device.
