    Hi guys, i wish to install A9lh on my new nintendo 3DS xl, i'm kinda tired of shitty bootrate...

    My settings :

    New Nintendo 3DS XL PAL (from Australia)
    Sysnand Firmware : 9.0.0-20E
    Emunand Firmware : 11.0.0-33E
    CFW : Luma3DS
    Menuhax installed to boot Luma3DS or Homebrew Channel
    System settings downgraded for gateway card
    Nand backup already done
    Title manager - Bigbluebox installed
    Boot NTR Selector installed
    Pokemon Sun CIA installed

    so decided to follow this guide : https://3ds.guide/

    - Do i really need to do all first steps until 2.1.0 ctrtransfer ? since i already have some entrypoint installed on my 3DS with easy access to homebrew channel.

    - Cant my settings may enter in conflict with A9HL installation ? I really don't want to brick my 3ds because of something on it.

    thanks for help.

    Since you already have access to Decrypt9 through HBL, you can start at https://3ds.guide/2.1.0-ctrtransfer .

    Make sure you back up both SysNAND and EmuNAND. At the end of the guide, you can restore EmuNAND to SysNAND and have A9LH with updated SysNAND. (If you don't want to switch to SysNAND, then you can just keep the EmuNAND as-is, but it's not recommended.)

    Also note that if you have any DSiWare or GBA titles, you'll want to back up their saves first, since they may get erased when copying EmuNAND to SysNAND.

    Once you've a9lh'ed you can fix the gateway downgraded settings if you want, via gm9

    As someone who did the process both on a previously hacked o3ds xl and a shiny new n3ds xl, my advice would be

    1 - Remember to not ever close the lid when it's on 2.1, either intentionally or accidentally (fall, etc)

    2 - dont worry about losing settings or anything, your 3ds is restored to what it was after you get otp

    3 - if you follow plailect guide, for some reason he makes you remove the sd card too much and put additional files on every few steps, you could cut the chase and get a few more files on your sd on the 1st transfer.

    4 - don't ever close the lid, put in sleep mode or let it drop (thus possibly closing the lid) while in 2.1 sysnand.
