So I haven't updated my A9LH for months and I saw this so called ShadowNAND which can load without SD Card. I was originally using plailects tutorial of A9LH before (the one with the RedNAND tutorial) and i'm planning to switch to ShadowNAND. What guide should I follow? I saw the ShadowNAND github page and theres otp required. Should I need that again? I'm currently on Luma3DS.
