even then, not officiallyThe only card confirmed is the AK2I
No cart has been officially announced to work with NTRBootHAX.
We already have a thread covering this
http://gbatemp.net/threads/3ds-unbricked-with-magnet-ds-flashcard.472585/
Theoretically my own research has shown that any DSi flashcart with a NAND (which should be all of them) can be rewritten to use NTRBootHAX. Really all someone needs is the cart and the source code for NTRBootHAX and they should be able to make their cart work with it, so long as they can gain access to the NAND.True, but the words "On the AK2i, all 0x4000 bytes are controlable, and can be used! Normmatt implemented this in his repository here:" make it seem extremely likely. You're right, though. There's no need for infinite threads speculating about it. When it's released, this thing will be front page everywhere.
Currently it works on 3 flashcarts, it'll release probably when we finish the 4th (which has been an absolute pain in the ass)
This and aswell as https://gbatemp.net/threads/3ds-unbricked-with-magnet-ds-flashcard.472585/page-68 with some more info on SciresM towards this matter.It was confirmed by SciresM that there are 4 flashcarts. 3 of them are already compatible and the last one is giving them trouble(which i think causes the delay). That's all the information we have right now.

Once flashed, you can flash them back. NANDs are read and write, which allows them to be flashed.That's good to know. Because I still use my AK2i in my DS Lite. But I have plenty of other stuff I'd never miss, like an M3 Real, two Gateway blue cards (one of which has outdated firmware that never even worked on a 4.5 3DS), and a bricked R4 SDHC clone (has the .in site on the sticker) that some vendor just threw in with my Sky+. Yeah, I tried to run legit firmware on it. Should have seen that one coming. But the fake site's files were horribly outdated. Besides, it was free.

Old DS carts like the M3 Real and R4 actually shouldn't work, unless they figure out how to change the ROM to read and write. Old carts used a ROM chip and were meant to be flashed once and locked from there. DSi carts had a NAND instead where pre-hacked ROMs were stored and swapped out by updates.

Then the cart has a NAND, I am no expert on every single cart. I am limited to the carts that I do actually own.Well, you may have a point with the M3 Real, but this bricked clone is not of an original R4. It's a clone of the R4i SDHC RTS Lite. It can be flashed. It's just that what I flashed it with bricked it for being a clone, apparently. So I need an app that can flash it before I can do anything with it. I sent SciresM a PM offering to help test it. Because I have a hard modded test unit, and I tested a custom 3DNUS release he was working on before. But I never heard back, so, I'll just have to wait like everyone else, I guess. But I've got nothing to lose trying to write to that thing when it comes out. It's already bricked after all.
