Software-based Factory Reset
As a “reset to factory defaults” function, two pins on the 7-pin connector
can be jumpered together using a standard 2mm electrical jumper. When
the intercom boots up, it will check to see if these pins are jumpered, and
if so, it will perform a “factory reset”. Which pins are jumpered together
determines the type of factory reset performed:
Jumper pins
2
&
3
: Erase the info.json file and all settings revert
to defaults.
Jumper pins
4
&
5
: Format the file system.
Because this is a software-based reset, the software must be minimally
functional in order to use it. In other words, it cannot be used to recover a
unit which has been loaded with a firmware image that does not boot.
