    Ok, so if they've released a firm...
    Uhh...
    I have one of their r4i rts carts. Is it safe to flash ntrboot to it now? Is there something I can do to back it up or help further development before I do it? I only have one system, and there's no CFW. Is it safe to go ahead?
    This is moving along quickly now that everything is being released, and it's hard to be patient...
    Another thing. I noticed that my cart appears to the 3DS as a legitimately released DS lite title (from the bomberman series, to be exact). Does every cart show as a different title, perhaps? I noticed from a video that a r4ids.com r4i cart will appear as such in the activity log, but mine shows that I've been playing bomberman. Is this known info?

    Yes, this is how every single recent flashcart works. To get around signing requirements, they spoof a whitelisted game. It's usually the same title, but may vary with updates.

    Run this first and take a backup. You'll want to select the r4i-sdhc option: https://gbatemp.net/attachments/ntrboot_flasher-zip.102456
    Then after running their flasher, take another backup. It would be useful to see both.

    Of course, if you have no CFW *you can't run any of those*. Attached is a nds flasher. It has not been tested at all, needed a bunch of modifications. (I should help @d3m3vilurr out with updating it at some point, sorry for the rapid changes) select the r4i-sdhc option. etc.

    regardless, ntrboot injection won't work yet.

    EDIT: forgot to attach. >_>

    Does the flasher have the ability to restore dumped flash images?

    Does that include R4 SDHC dumps?

    Yes, this was a build *specifically* created for that.

    Ok, cool. This is nice to know.
    At least you kind of acknowledged the fact that I don't have CFW.
    I've read the guide. At least twice. I promise. I just read it a third time to avoid asking unnecessary questions. So... you're saying the nds flasher attached won't work then?

    And let me make sure I understand this. If I've gotten a solid reply to this, I'm sorry. I'm scatterbrained. It's a problem.
    If I don't have CFW, can I dump my cart's firm in any way so I can have something to restore when I'm done? Being able to restore the flashcart at the end of everything is the foremost reason that I'm waiting so long to try anything.

    I'm sorry if this post seems scattered. It might not, but that's how I've felt for the past half hour (or however long I've spent writing this in a way where I don't ask any unnecessarily stupid questions).

    Thanks for being patient so far. The 3DS is not a thing whose inner workings I understand. Then again, I can't truly say that Windows is either...

    The build is for experimentation, so you can flash (modified?) backups to test stuff. For instance, flashing a backup from a b9s cart to try on your cart. Be sure to make a backup before doing anything of the sort, and you should make sure that it isn't garbage (full of 0xFF or whatever)

    So in theory your flasher should work on other r4i-sdhc variants, right?

    Have you guys taken a look at their new flasher? Did it change anything relevant?

    I haven't received the cart yet, but i've seen the PDF tutorial and, it has a link to a "InstallFirm.zip" file. There is a OTP.bin inside. WTF.

    For some reason R4 decided to dump the bootroms and their OTP for us.

    I got my card today :toot: (The magnet was broken xD)

    Dumped the flash right now, here it is. (I checked it with a hex editor, its not just FF.)
    Will later flash the card with the r4i-sdhc.firm, and upload later the other flash.
    (its a normal .zip)

    EDIT: Btw, i see now the problem with my r4i-3ds card. It only goes to 99%.

    EDIT2:
    Oh, i just saw something interesting: The b9s card is a r4i-3ds RTS card, as you can see here: https://github.com/kitling/flashcart_core/issues/14 https://github.com/kitling/flashcart_core/issues/14#issuecomment-324944317

    EDIT3: I flashed it with the r4i-sdhc.firm, it shows as "Touch! Bomberman Land" on the home screen.
    EDIT4: IT BOOTED! :toot: (I used of course the R4i-3DS V1.84b kernel/whatever)

    So to confirm, you flashed the r4i-B9S card with r4i-sdhc.firm and it works? Which flasher did you use and where did you get the r4i-sdhc.firm from?

    Yes, it worked. I used this: https://uploadfiles.io/2wl7t
    Its the flasher from the official site. (1.0)

    Was yours bricked originally? The problem I'm having is the official flasher won't read the card. The flasher that @Kitlith provided appears to restore firmware to it, but when I do a back up it's the same.

    The end screen states:

    Reading...
    Checking 003F0000
    Writing Chunk 003F0000
    Chunks written 64 (00000040)

    Restoring Complete!

    When you restore, then backup, your firmware with kitlith's flasher, is the file the same as the one you started with? We need confirmation the writing works properly.

    No.

    So I made a backup (backup A)
    I restored the firmware and get the output I posted above
    I made a second backup (backup B)

    Both backup A and B are the same. So it appears the flash did not work.
