His post was originally written as "y" before going back to edit with more description. That's a poor way to go about asking for help, but it's not out of the norm for a new user who does not know or have prior forum etiquette. Someone who is willing to help should look past this "misstep" if we are to assume this is his first time offense of bad communication.
Going off his title containing "Section II", persons with prior experience installing custom firmware would be stumped if they saw the magnet failing to trigger booting SafeB9SInstaller. There is nothing funny about being told you did something wrong when you know for sure everything in the procedure was done correctly up to that step. Convention dictates that NTRboot supposedly "works for all 2DS/3DS systems", but those two users I pointed out demonstrated this isn't the case. One of the two has done NTRboot for multiple systems; the other user has video proof the hack works on his O2DS but failed on his friend's O2DS.
Just in case the OP was having this exact bizarre scenario, it's best to give him the heads up so he knows the problem (could be) not him sucking at following the 3ds.guide instructions.
