Here is the link, and it works, but unfortunately, 1.32.00 will not let you downgrade at all.
I’ve tried downgrading and although it looks as if it is doing it, it will stay at 1.32.00.

So the original firmware was published, but if you are at 1.32.00 there is no method currently to downgrade… (sad face)
