If anything does not work out you delete all files and copy your backup files on the device, all back to the old.
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
