I don't get it why hasn't anyone done it yet. While downgrading, your New3DS has a higher risk of bricking. But Its not the case for Old3DS users. Why? Why haven't you installed arm9loaderhax yet? Comments and the poll too. Advantages of arm9loaderhax - That thing is fast.... sysNAND boot speeds for all CFW. - No need of an EmuNAND. Feel free to update your sysNAND. This also saves ~1GB space on your SD Card. - sysNAND brick protection. - Region Free (If using Luma3DS) For those of you who rely on Cart games, (Which you bought yourselves) (and you dont use CIAs) people are working on a solution for A9LH which will make your 3DS boot even without the SD Card (i.e. The CFW would be on your NAND!!)EDIT:SHADOWNAND! To get help while installing a9lh, either post your query here, here or here.
