Is there any way to downgrade my 3ds firmware 9.6.0-24U to something in the 9.2.0 range? If not, can I expect that there ever will be?
There is no way to downgrade from X to Y, except if X has an ARM9 exploit.
The last ARM9 exploit (usable) we know was fixed in 9.5, and needed a kernel exploit that was fixed in 9.3
Is that to say if you're on 9.4 you're not able to downgrade because the kernel exploit was fixed?
Edit: On second thought, I'm not even going to pretendNo, but I have heard of people buying a 9.2 console exchanging motherboards and then returning it.
