Description of the issue:
In the HS4 Storefront Lock (HF28, HE28, HP28) units with firmware device number 196, version 00.20 of the firmware has a bug that will eventually corrupt and delete the security code of the lock, making it impossible to open the XS4 One from the outside by using a credential (card, fob, phone).
If your storefront devices remain on this firmware version, the lock will eventually experience the memory corruption and stop working. This can occur anywhere between 7 days and two years after installation. Therefore, it is imperative that this firmware is updated as soon as possible.
Resolution (Complete ASAP):
The firmware on the lock must be updated to version 00.21.
SALTO ProAccess SPACE installations:

These instructions assume an offline lock, but if your locks are online BLUEnet devices, please respond to this message for assistance pushing firmware updates over the air.
