Hacking R4i-B9S flashcart: tested and impression

Do it doesn't seem like my cart works, so here's my backup

I can tell by the file size that it didn't work

I haven't been able to follow this thread as tightly as I was before. I've been busy harassing the Ace3DS team instead.
I can only do so much harassing.

I'm curious. Could you take an SDHC 2017 card and flash it with the b9s r4i firmware? Correct me if I'm wrong, I've been out of the sdhc b9s stuff since august.

I flashed the R4i B9S image to my SDHC 2016 cart so it's possible.

Quick question that I will elaborate more on later
So can I turn this cart into an NTRBoot cart?

Are you sure that card has flash memory and not ROM chip? And does trying to dump the image a second time give the same file size? I think it should be 2MB if fully dumped.

Ok, so does that mean a non-B9S card can be flashed with ntrboot now? And is it reversible without having CFW beforehand?

The non-B9S cards have to have the B9S card's backup flashed to them. I don't know if it's reversible without CFW though, it would depend on if there's a version of NTRBoot flasher that can work on stock systems.

It comes up as 2MB on my end, so I dumped it again and upped that straight to filetrip

I don't believe you successfully backed it up, it's just bunch of FF.

Weird, I backed it through the flasher posted in this thread

I personally wouldn't buy from r4i-sdhc their cards always have a "time bomb" where they expire after a period of time with their DS mode flashcards which seems too sketchy imo it just turns me off from even bothering to buy from them again i wouldn't even be surprised if this new card also has some type of time bomb as well.

There are a couple different versions of the flasher in the thread. There's one with a post specifying it ignored checking for a matchig NOR. Try using that one if you haven't already.

I am finding like 3 different results in 2 different threads, please help me out here and quote the right post(s)

 

[RedBlueGreen]

Yeah, the one above had a sanity check that would fail if the NOR was garbage.

Try this.

The flasher in this post is what I used.

I think my cart is the issue.
I restored the backup from this thread and said that it "Restored successfully." But dumping a new backup after restoring the previous one only resulted in a backup made up of "FF"

I've got the R4i 3DS WiFi RTS (not the R4i B9S) but I've restored mine back and fourth a couple of times now, just to keep things simple I made a zip (preserving paths) containing three versions of the restore procedure:

• Restoring to/as R4i 3DS WiFi RTS (my backup.bin and @AngelSL ntrboot_flasher with additional nor sanity checks removed if your nor is trashed/bricked)
• Restoring to/as R4i B9S in nds mode (@pandavova nds backup.bin and @AngelSL ntrboot_flasher with additional nor sanity checks removed if your nor is trashed/bricked)
• Restoring to/as R4i B9S in ntrboot mode (@pandavova ntrboot backup.bin and @AngelSL ntrboot_flasher with additional nor sanity checks removed if your nor is trashed/bricked)

I don't know how to make it any easier

One gotcha here is that (at least for me) there are only 7 chunks restored, and when restored to/as R4i B9S ntrboot the cart is not registering as inserted if your device is booted "normally", but loads up as it should using sleep/magnet. When restored as R4i 3DS WiFi RTS or R4i B9S nds it should register (at least for me) as Bomberman*

The zip is larger than 2mb so I couldn't upload it, here is a link

Yeah my cart looks like the issue. I restored those and got backups with "FF" again.
My cart is the "NDS" version of the cart, although it is using the Bomberman header

Which cart, exactly, do you have? R4i ...?

That is something older I guess... if someone having the same cart (stock) could dump their flash (using the ntrboot_flasher builds from this thread) then you could try restoring that instead?

Unless there are some other differencies between that cart and the R4i B9S/R4i 3DS WiFi RTS? Perhaps @Kitlith et. al. knows more about that?

Well I’ve opened my cart and took a few pictures of it
