Hi Butters, the device is not bricked. When I turn it on, the logo appears and then an image of a PC and a GPS connected to it appear on the screen. If I connect it to the PC when it is turned off, the device starts with the image described earlier, partially enters the MTP in the sense that Windows sees it and a window with folders and files appears, but the .System and .Spotlight-V100 folders cannot be seen, although the setting for hidden files and folders to be visible is checked. Garmin Express and WebUpdater also see the device, but Total Commander and RMPrepUSB do not see it. If I start it from the button, then I quickly connect it to USB, enter normal MPT and this time the PC can see the hidden files and folders and Total Commander and RMPrepUSB see it. I formatted it with RMPrepUSB in several ways, but in vain. The boot sector remains untouched, and in RMPrepUSB it always appears up, at Drive, Garmin dezl System. I also tried with SD card which I copied in Garmin\Updater\2826\ the files 0E.bin, 7F.bin, 9E.bin, Ldr.bin and update.txt, but it does not start 'loader'. When creating the GarminCure3 file I used an rgn file, dezl 580 (2826), version 4.
