Do I have to install A9LH afterwards and start at step 4 then ctrtransfer to 2.1 after I am finished with step 16?it will move your 3ds to 9.2.0, in the a9lh install process, you'll have to ctrtransfer to 2.1 regardless, but you'll still need to ctrtransfer back to 9.2.0 (or restore a nand backup) afterwards
