I did mention that I had made a full back up to do precisely that,

What I was worried about was the bootloader getting updated as I thought that you couldn't downgrade that.
My device has no sd slot so I wouldn't intentionally upgrade the bootloader for that function.

So am I right to think the only way I would update the bootloader unintentionally would be updating through TomTom Home? ( which shouldn't happen as it doesn't offer me a new NC above what I already have)
I just didn't know if updating the navcore also updated the bootloader using the method in this thread, which is what I wanted to understand before proceeding. Can you just put me straight on that?

Many thanks for your help

Affects not all devices and changing the NC often works fine.
You'd have to update your bootloader for SDHC support but for the NC you should be fine.

Doesn't appear to work with my GO910 and 9.430; did with 9.026 and 9.051 but your 9.430 is stable so I use it.
