Thread: Garmin Nuvi 40 boot problem

Big thanks to catymag.
I have same ideas:
- used instruction by me: "How to unbrick a nüvi - step by step guide"
When I plug navi via usb cabel, navigation do nothing, then I used bootable mode with finger on display.
GarminCure3 then told me, your navigacion is udatede but whatever.
Of course, no USB connection during the process.
Then was used downgrade with me to older firmware version specifically from 620 to 540.
Process was complete! :D then I was happy, my garmin lives.
No problem with connection to via usb.

Today I would like to tray take operation software system to Nuvi 1390.
When I try it yesterdey, webupdater and other one garmin soft were loosers...

Not giving up yet.
