As stated in note (1) behind first spoiler of initial post [Only registered and activated users can see links. ], that method works for some devices but only if they aren't bricked. Generally only some older series can use that way of accessing preboot and it's universally not possible in more recent devices.

Additionally some older "special-use" series access preboot by holding the screen's LOWER left corner while powering on/connecting USB. I don't recall if dezl 580 is included in those however.
