When a Rock is factory reset, all profiles, security events, and certificates will be deleted from the device.
There are two ways to reset a Rock to factory settings.
Reset via the Admin Portal
If you can see the Rock in the Admin Portal and it is online, deleting it from the admin portal will cause it to reboot and perform a factory reset.
Remove the Rock from the wall and ensure that the tamper condition is indicated on the device’s display. Short the ‘Hold’ signal (Blue Wire, normally connected between the Rock and the ACS panel) and the Tamper signal (Violet Wire, normally connected between the badge reader and the Rock) to GND for 15 seconds until the Rock reboots and performs a factory reset.
