Danalock V3 Firmware
Please note that there are two similar firmware files for the Danalock V3 main firmware. The Salto reference number printed on the original product box will end with the letter M if the lock was produced after January 2024. This indicates that it is the newer version. If the reference number does not end with M, the lock is the pre-2024 version. If you no longer have the box, you can scan the QR code inside the lock to view the product details. Look for the Date field to determine which version you have.
