Thread: DNX 7260BT no NAV, garmin module memory wiped, cannot access garmin module

Do you mean you have to manually engage preboot for it to be seen by Updater but it's seen by Dev Mngr regardless of preboot mode (i.e., if it's just plugged in). If so, that seems contradictory.

yes , the image with device manager shows what is showing when the preboot (wires)ISN'T connected

The image with updater shows it when it is CONNECTED(the preboot wires)

Which RGN file did you upload- mine or some other? Have you tried to flash V4.31 fw previously? If so, post a copy of it or a link to that RGN please

.
I flashed garmin's original file from their site where you can download the update.gcd it's impossible to flash ORAK's gcd as it's unavailable.
I will edit this comment and add link to the rgn from garmins site when I get home.

Also please absolutely confirm or otherwise the 3rd bullet point in my previous post regarding preboot being available without you having to manually manipulate anything. I think you mean by the following that when connected it always shows in Device Mngr without you doing anything but i need to be sure:

Let me start with this from start , before connecting preboot wires it shows up in device manager for few seconds and disconnects, as so on
But when I connect the preboot wires it shows the same thing but it doesn't disconnect right after few seconds but after like around ~2min

However ....It's unclear to me what you mean exactly by this (then my quote about sw Ver )

:
so , you can enter in a test mode src+att+reset[red traingle](Please do not be influenced by the photo that the board is damaged, I took the photo because it was one time it was disconnected because of my bad work connecting the tape connectors)

where you can see info about the versions and status of the unit , and in that mode you can check what version the navi board is , and before doing anything it was 4.30, and after using the updater it was changed to 4.31 , and here's the thing with the updater , as I've seen in the ORAK's comment , it showed the current version of the navi board , but in my situation it doesn't show the navi version that is currently but rather the version that was originally when the unit was sold

EDIT
im in home and checking the files you sent me and theyre the same that i used

IMPORTANT PART 2
After uploading your file it did change in the dev mgr to this.
