No, he means, can we downgrade emuNAND to 2.1, then using that emuNAND to get OTP.bin without touching sysNAND.
Since he fears of brick enough that he doesn't want to touch sysNAND no matter what. Which impossible.
For the people who still pushing
@BlueFox gui to do A9LH, I think you should stop or guarantee him of bricking.
Since he already said he will do A9LH only when someone gonna buy him another new 3DS if he got brick.
As I & Plailect said,
EVERY time you modify your system, there is always the potential for an UNRECOVERABLE brick.
If you can't guarantee him of bricking (by buying another one if brick), please stop.
He has the right to fear, and has the right to choose what he want to do with his 3DS.
If he updated sysNAND by accident or Nintendo can destroy emuNAND + Menuhax setting, he can't blame anyone but himself.
Because this is his choice.
