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.
