The truth is that I never managed to enter preboot mode with this device, with the classic method, neither with DS firmware, nor with dezl firmware. I've done it many times with other devices, but not with this one. It enters the preboot mode, when I put a card in it that contained Garmin\Updater\2826\ or Garmin\Updater\2267\ and the files 0E.bin, 7F.bin, 9E.bin, Ldr.bin, update.txt, as appropriate, depending on the installed firmware (dezl or DS). When I inserted the card, 'loading' appeared on the screen and it remained locked at this point. Then when I restarted it, 'System software missing' appeared on the screen and in this way it automatically enters preboot mode. This way, using Updater, I install one firmware or the other. I've done this several times. When it had DS firmware all was OK, when it had dezl firmware, the touch screen was completely inactive. I tried to recalibrate the screen, but failed to enter 'screen calibration' mode. Then, with the firmware dezl, in the device, I inserted a card again with the files described above and after 'System software missing' appeared on the screen I used Updater with the Cure3 file I wrote about earlier.
