    As noted by dark_samus on 3dbrew,

    This is currently not ready for general usage -- I'm the only one who has tested it, but expect OTPless A9LH installations for N3DS users soon (only an arm9 exploit required, so it's still only for those on 9.2 or below/those who can downgrade to 9.2).

    If you have a New 3DS with a hardmod, feel like you understand everything written above, and know what you're doing (IE, no noobs), there's an alpha on my github that you can test out.

    If you don't, WAIT FOR THIS TO BE BETTER TESTED.

    Credit to dark_samus for finding the vuln, delebile for his key bruteforcer, Normmatt for helping dark_samus mod the key bruteforcer, Myria for helping figure out some conditionals, as well as answering questions leading to the discovery of the vuln.

    Taking this second post to reaffirm: Do not try to use this if you don't know EXACTLY what you're doing, or without a hardmod.

    This is fantastic! Great work to all those involved, after going through the OTP process in its early days I can definitely appreciate the hassle this will save people. (Given they've got a stock ≤9.2 N3DS)

    Well, it was certainly fun finding my first vuln... Sure it builds off of other stuff, but I found it with less than 4 months experience.... after that it was just waiting for everything to line up properly (which actually happened awhile ago, but it was thought to be un-exploitable). It's still insane to me that I actually found a vuln. Props to everyone who helped (as listed in the credits) and thanks to #Cakey for support and helping me through my noobness :)

    So in layman's term, the only requirement to use this is a 9.2 New 3DS?

    worked fine here, if anyone is curious. 9.2 to a9lh almost instantly, no otp.bin.

    get UnsafeA9LHInstaller from SciresM's github if you're brave. only do it if you have a hardmod and New 3DS.

    If you have to ask, you should NOT be using this yet.

    nvm found the release tab on github... i thought I would have to build it myself and stuff

    Huh cool, it is just a homebrew app! I wish I had this when I installed A9LH on my New 3DS... would have saved a lot of time

    To be honest, I don't think anybody should be sharing steps here. I don't want to sound elitist, but this is alpha software which could brick your 3ds (no disrespect to the devs - but I'm sure they would agree that this is a possibility at this stage). If you can't find the GitHub repo and figure this out without instructions, just wait for a release.

    Im dying to try this(just out of curiosity) but I don't have a New 3DS lying around right now. I'll just wait for a couple of more tests and I'll buy myself a new console just to try it out.
