EDIT - Inadvertent modifications to any of the items in the Debug menu can render the device inoperative, and with a touchscreen that risk is much higher. There is nothing in this menu that benefits the user in any way, so I am removing my comments out of respect to Siglent support who have been helpful to me here in the forums. We've got a good thing going with the upgrade hacks and I don't want to give Siglent any reason to start locking things down more securely.
