Thread: Bricked my nüvi 1490...

While waiting for a reply to my previous post, I will continue with kunix's suggestions:

Can you please confirm that using a healthy unit? It's not dangerous to flash an original boot.bin alone. Just rename RGN from 082701000620-org.rar to 097201000620.rgn.

I'm reluctant to flash anything into the healthy nüvi 1490T until I know how to salvage the bricked unit. I did create a backup of rgn 41 of the healthy unit though.

I get the message "No updates are available for your product":

082701000760-true.rar contains the original 827's boot.bin.
I think it's not harmful to flash it again (you've already executed it as ldr.bin).

Same happened as in post #14:

The screen of the unit then shows the text "LOADER" for about 10 more seconds and then repetitively briefly shows "SYSTEM SOFTWARE MISSING" until I disconnect the unit from the PC.
