There is no info at all on the 8.040.9613 navcore. I am not 100% sure, but with the bootloader 1.0009 I think you are out of luck. The bootloader 1.0000 is used on somehow crippled devices (either devices that will not accept proper bootloader 5.**** or for marketing purposes) which only works with navcore 8.040 (OneXL) or 8.041 (One).
Also it is most likely that you will brick your Tomtom if you do attempt to flash the bootloader to 5.****. The only success story I have heard of is flashing the 1.0012 version to 5.****
