Screenshots and video tutorials

CAS3 EEPROM Editor with the ISN Predictor listing 64 candidates — **CAS3 ISN Predictor - all keys lost** - When the ISN can't be read, HexTool generates all 64 zero-shot candidates for a 64-mode CAS3 - the true one is guaranteed among them - then restores it into the EEPROM alongside VIN, mileage and keys.

BMW CAS4 / CAS4+ Editor showing decoded VIN, mileage, ISN and key records — **CAS4 / CAS4+ Editor** - Opens the encrypted CAS4 flash dump and lays it out in plain text: VIN, mileage, CAS ID, EGS ISN, and the crypted ISN decoded to the plain ECU ISN. Key records are CRC-validated, and can be reslotted or deleted.

BMW CAS Flash Recovery matching the correct flash version to the EEPROM via AIF — **BMW CAS Flash Recovery** - If the flash number can't be read, the AIF at offset 0x0FDE identifies it straight from the EEPROM. HexTool matches the right flash, flags when a newer safe version exists, and downloads it into the right pane.
