Thread: Need Help with Bricked nuvi 1490

I updated it with Garmin Express. Then I loaded the 2020map.
Everything went fine and tested the unit fully before installing it on the windshield of my daughter's car.
In few days she calls me that it bootlooping and it haas been doing that ever since.
The sd card doesn't work either. Heres what I did:
With my original firmware I extracted the boot.bin and saved it as Ldr.bin
I created the update.txt with the code above
I formated a 2Gb and a 8Gb card fat32 and created Garmin\Updater\0972\ where I copied both files. Tested both sd cards.
Then completely shut down, insert the sd card and started.
No "loader" message on screen and finally it bootloops again. (when I power it up it goes to GARMIN logo screen and stays there for 20 seconds or so then the screen flashes white and restarts)
