Thread: Bricked my nüvi 1490...

Okay, it's ready.
Unpack it to an empty SD card, so that 5.bin is located at SD:/5.bin.
Insert the SD card into the broken device.
And flash the RGN file using updater.exe in pre-boot mode.
If it works fine, your device would be visible as 14xx in pre-boot mode. And you would be able to use 14xx's boot.bin.
Let's cross our fingers and hope it works. Coz if it flashes only 5.bin or only 43.bin, your device would be completely killed most probably. Hardware repair would be needed.

Note, that boot.bin inside 082701000760-cure972.rar is patched to load update.txt and to allow flashing regions 5 and 43. Original boot.bin doesn't do that.

Alviora means that your problem can be solved by unsoldering the flash chip and flashing it with a dump from a healthy device. This is the hardware repair method I was talking above.

I realize there's only one way to do it right and many ways to do it wrong. So before I proceed, please confirm that my understanding of what I need to do is right:

1. Extract the RAR file.
2. Place the following contents in the root of an empty microSD:

• Garmin\Updater\0827\update.txt *)
• file 5.bin
• file 43.bin

3. Make sure bricked 1490 is switched off.
4. Place microSD in bricked 1490.
5. Drag & drop 082701000760.rgn onto Updater.exe.
6. In the Updater.exe window, select "USB Device".
7. Bring the bricked unit into pre-boot mode and click "OK" in the Updater.exe window.

*) update.txt contains following commands:
xrgn,5,1:/5.bin
xrgn,43,1:/43.bin
reboot

Did I understand things correctly?

Just out of interest... what's the difference between the xrgn and the rrgn command?
