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?

I'm so glad it worked
The fact that it was able to boot up to the mass storage means that 972's bootloader has successfully executed 972's fw_all. So your device should be healthy.
You don't need to do anything. Just let it boot.

Also did you notice that post #35 in this thread was my post number 666? So your unit was cured using a bit of devil's magic! Now it's possessed!

@smokefree

Yupiiii you have now working nuvi

@kunix

You again prove that you ar " best of the best "

OK, thread marked [Solved]! But let's not close it in case some other poor soul needs some black magic exorcism. A lesson here for us all that sometimes 'foreign' fw bin files can be flashed to the wrong unit if they're in the HWID folder, and that some bins will and some bins won't. I've been following this thread with some interest.

PS: Would you like an old post somewhere deleted so that your post above becomes 666 kunix? [A rhetorical question, wouldn't wish to spoil the 'dark magic']. On a serious note, are you able to patch ALL boot bins to execute such non-standard rgn writing or is it possible only on some?
