Confirmed Working: How to Write Skylanders Nfc Cards on Android Step by Step

Catch up with Confirmed Working: How to Write Skylanders Nfc Cards on Android Step by Step. Explore expert viewpoints in full detail.

Writing a working card requires three core elements: your verified Android device, blank Gen2 CUID cards, and the backup data files.

Backup files circulate among preservationists as 1,024-byte `.bin` files containing the raw hex image of the original figure, alongside key files containing the calculated sector keys.

Step 1: Install Mifare Classic Tool (MCT)

Download the latest open-source build of Mifare Classic Tool from F-Droid or GitHub.

Step 2: Prepare the Key Files

MCT must authenticate all 16 sectors before it can overwrite them.

  1. Open MCT and enter "Tools" -> "Edit/Add Key File".
  2. Create a new key list or append to "extended-std.keys".
  3. Skylanders uses derived keys for each sector. Add the global master keys

and known static sector keys used across character dumps.

Save the key file.

Step 3: Convert Character Dumps

MCT reads human-readable `.mct` or `.dump` files containing ASCII hex text,

whereas raw backups are usually binary `.bin` files.

  1. Use an online or mobile file converter (like a hex editor or Skylanders MCT converter)

to translate your 1KB `.bin` character file into an MCT-readable text format.

  1. Place the resulting file into the internal storage directory:

`mifareclassictool/dump-files/`.

Step 4: Execute the Block 0 Write

  1. In MCT, tap "Write Tag".
  2. Select "Write Dump (Clone)".
  3. Check the box labeled "Show Options" and ensure "Write Block 0" is enabled.
  4. Select the dump file of the character you want to flash.
  5. Select the key file you configured in Step 2.
  6. Hold your Gen2 CUID card flat against the back of your phone near the NFC antenna.
  7. Tap "Start Mapping and Write Dump".

Keep the card steady for the entire three-second process. MCT maps the sectors, authenticates blocks 0 through 63, and writes the manufacturer block alongside the encrypted gameplay data. Once the screen confirms 64 blocks written successfully, the card is ready for gameplay.
