PS: To reflash region 16 it's much easier to use the SD method with xrgn write command then no preboot is required.

@Castus
Member janch gave you a thread link above, look at [Only registered and activated users can see links. Click Here To Register...] there for how to use SD for backup and re-write of region 16. Links for both methods are prominent at the top of first post there:

Garmin devices Logo.bin files

These logo.bin files have been posted in some threads in various sections here on forum or I've done them with Gir Editor-
I thought it was more confortable to have them all in just one thread.

Please help me to enter to preboot mode on Gamin Dezl 580

I tried the way described but I can't succeed. Is there any special way ?

Edit:

Finally after more time access in preboot mode by entering into the hidden menu
- by pressing and holding the battery symbol and then connecting the PC USB cable.

As stated in note (1) behind first spoiler of initial post [Only registered and activated users can see links. Click Here To Register...], 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.
