As long as the fault can be proved to be a hardware issue, changing the software on the device doesn’t by law void the warranty.
With that said, DMS as an entity, shouldn’t be replacing the firmware on the device from a manageability standpoint. Something like that would need someone in the know to keep up with firmware updates in a way that wouldn’t brick the device, and in a volunteer environment such a person couldn’t be guaranteed.
I’m not in any way recommending that we modify the device, just that we are surrounded by makers and someone might come along an “help” the device. Since it’s possible, we should probably have the chair make a solid rule about whether the device should be “upgraded” or no.
I personally lean towards no as well.
