    So I'm in a bit of a pickle at the moment, or at least I think I am. I have a (New) 3ds XL with Luma CFW, which I installed about 1 year ago now, and have been using fairly regularly without any issues until a few days ago.

    The micro SD card I have been using in my 3ds, just and ordinary 32 GB Sandisk Ultra, has suddenly died without warning (completely unresponsive from all manner of devices: other 3ds', smartphones, laptops you name it). So I am currently in a situation now where I have a new SD card and I'm trying to figure out how to reinstall cias and basically get the CFW'd 3ds back into full functionality as it was pre-SD card meltdown.

    I have spent the past couple of days perusing forums, videos and re-consulting the 3ds.hack.guide website to try and at least get access to a chainloader but to no avail. How can I go about reinstalling the necessary tools, like FBI, so I can get full homebrew functionality with my CFW'd 3ds?

    Thank you anyone for your assistance, sorry if I sound like a philistine in this request - it's been a while since I last dabbled in installing CFW and I have forgotten most of the particulars.

    Normally, most of us are going to tell you to follow that guide at the beginning and to the letter but seeing as you've attempted it. Well, here you go...

    The restoring Luma3DS CFW (boot9strap) for those who've installed it before, lost their SD setup, and mostly forgot how any of it works, Shortcut Instructions.


    1A. Reformat the SD card in FAT32 + (32768) 32 KB * cluster size using guiformat.
    - or -​
    1B. Reformat the SD card in [ Format: FAT32 | Cluster Size: 32 KB * | Partition: Primary | Disk: MBR ] using MiniTool Partition Wizard (free edition).
    • * Optional: If the SD card is 128 GB or larger, you may instead reformat it in FAT32 + (65536) 64 KB cluster size.
    • Recommended: Check the empty card in a full Write + Verify Test with H2testw (Windows), F3 (Linux), or F3X (Mac).
      • If the result comes back clean without any hardware issues, delete the *.h2w test files.
      • If there was a reported error, replace the unreliable card.

    2. Download the CFW starter kit - 05.21.2019.7z archive and extract the files in the SD root.

    3. Select (x) Show NAND or user string in System Settings in Luma3DS v9.1 configuration.
    • If you're new to Luma3DS, have this as the default setting until you're more familiar what each one does.
    • I highly recommend you don't select the last two options like this:
      • ( ) Set developer UNITINFO
      • ( ) Disable ARM11 exception handlers

    4. Follow Sections II – VIII: [3ds.hacks.guide] Finalizing Setup

    Here's a tutorial video in how to Rosalina inject Homebrew Launcher:

    5. You should have access to FBI through HBLauncher by now. The rest is up to you refamiliarizing yourself how everything works.
    • Optional #1 : This archive contains both *.3dsx and *.cia sets. Refer to the Update Changes Log for information about the homebrew titles.
    • Optional #2 : You can Rosalina inject into the Homebrew_Launcher_Wrapper if you like having a dedicated HOME Menu icon.

    Hey, thanks for the response.

    I have formatted the micro SD card and copied all the files from the starter kit and then checked "Show NAND or user string in System Settings" in the Luma Configuration Menu. However, I can't launch Rosalina from the Download Play app as per section III, the L+down+select button combination does nothing. Presumably I have to follow the steps in the Rosaline install video, but for the record I have Luma 7.0.1 installed on my 3ds which doesn't seem to be compatible with this method...

    Make sure the buttom combo is L-shoulder + down (d-pad) + Select.

    The boot.firm in that archive contains Luma v9.0. If Download Play does not work, try inject into AR Games or Face Raiders.

    Edit - Luma v7.0.1, hmm... Oh, you don't happen to be an old timer from the (arm9loaderhax) A9LH era?

    Because if you are, forgot about everything I wrote. The problem is you need to upgrade: https://3ds.hacks.guide/a9lh-to-b9s

    I can confirm that I am pressing that exact button combo; no luck with Download Play, AR Games or Face Raiders. Are you certain there is no compatibility issue with the version of Luma I have installed on my 3ds (not the SD card, which has 9.0 as you said)? I certainly don't recall Rosaline when I initially installed the CFW like a year ago.

    In the post above, I made in edit realizing what your problem could be. You may have an outdated hax that does not work with current CFW standards.

    I performed all the steps in upgrading from A9LH to B9S...and it worked like a charm :D I can now access Rosaline in the Download Play app.

    Cheers for your help bud, I'm sure this will be useful for a bunch of people.
