: Overwrites individual corrupted sectors without modifying intact data.
: Cards are split into distinct sectors (16 sectors for 1K cards; 40 sectors for 4K cards).
: Instantly pulls the unique identifier from Block 0. Mifare Classic Card Recovery Tools Beta V0.1-
Place the card onto the NFC reader. Use the recovery tool's initial scan function to isolate the UID. If the tool returns a hardware error immediately, the tag may not be a compatible MIFARE Classic chip—for instance, trying to read an NTAG213 with MIFARE recovery software will result in a timeout or error because NTAG uses a completely different architecture. 3. Check Sector Integrity
: Appropriate USB serial drivers (e.g., CH340 or dedicated reader drivers) must be installed to ensure the OS recognizes the device. Place the card onto the NFC reader
: The final block of each sector stores the access conditions along with secret Key A and Key B .
Once the correct keys are matched, export the raw hex dump. If specific data blocks were corrupted due to a premature card disconnection during a write cycle, use the function to push the correct hex data back into the damaged sector. ⚠️ Important Considerations & Limitations Once the correct keys are matched
Before inserting the card, connect your reader and ensure that the Mifare Classic Card Recovery Tools interface initializes properly. 2. Read the Card UID
Follow these steps to analyze, read, and recover a corrupted card's contents. 1. Analyze the Hardware Configuration
Run the recovery scan to evaluate which sectors return valid data and which sectors are locked.
