Only with the HD 590 does it change to the small error message after flashing. (The HD Zumo 590 and the Garmin Zumo 590 have the same HW ID.)

That seems to confirm what i was suggesting, that the zumo 595 operating firmware is not playing nicely with the data in rgn16 of the HD 590 (which has a different logo splash than zumo 590/595. It seems the likely cure will be to flash the Garmin logo splash to replace the HD one.

That sounds possible! But you are dealing with a stupid newbie here! :-) Can you tell me how to dump rgn16 with Ldr.bin and 'rrgn' text command, please?

Ok, baby steps then:
1. What you need to do is dump the 'standard' Garmin logo from a virgin zumo 590 or 595 and it sounds like you have a zumo 590 available, correct?
2. You should also make a copy of the HD 590's logo in case things don't work out and you need to restore it.
3. You need to flash the zumo 590's logo to the converted device.
4. You can learn how to make those dumps and flashing using sd card by reading [Only registered and activated users can see links. ] in the thread you linked in your initial post.

WARNING: If you don't understand the exact procedure please ask before going ahead. You need to use the correct Ldr.bin (boot.bin) depending on how you chose to make your conversion to 595 - i.e., depending on whether you did a hybrid or full firmware conversion. In the former you'd have used the original 490 boot.bin combined with the remained of the 595's fw components. In the latter it's as it sounds, the full (original) fw of zumo 595 would have been flashed to the HD590 which means it's required to use the 595's boot.bin as Ldr.bin in the sd card. From here-on the risk is entirely yours. Any flashing carries risk, non-standard flashing is quite riskier.

EDIT: I see you added something while i was making this post. Forget about looking for the logo in the firmware. It's in region 16 which isn't normally flashed using a standard fw file.
