Hacking R4i-B9S flashcart: tested and impression

[Spwnrpe]

From what I've read there are successful attempts flashing (NDS?) r4i-sdhc firmware over the original R4i B9S, on a R4i B9S? I'm interested in the (almost) opposite, flashing B9S to a R4i 3DS WiFi RTS (stock firmware). Has that been done? Successfully? If not, should I attempt to flash a backup from a R4i B9S (like @pandavova posted) on my R4i 3DS WiFi RTS using an already modded O3DS and the ntrboot_flasher posted by @Kitlith in this thread previously?

Was yours bricked originally?

No, i didnt even try the first flasher.

I got my card today (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! (I used of course the R4i-3DS V1.84b kernel/whatever)

Could you please dump the flash after you've converted it to a "normal" flashcart and upload it here for us?

Also interesting, has anyone revived a seemingly bricked R4i (3DS/B9S) using the ntrboot_flasher build and some backup.bin posted in this thread?

Wanted to do it, give me time xD

 

[pandavova]

Ok, here its is. There are two files, the nds.bin and the ntrboot.bin.
(It's a normal .rar)

Is it possible if you could dump the .nds file from godmode9 with your cart in ds mode?

Yeah, will the dump the nds file. It will prob. be the same as in https://github.com/kitling/flashcart_core/issues/14#issuecomment-324944317.

Waiting to get my new card. @pandavova Does the new flasher work correctly 100% with reverse flashing the B9S Cards? I don't want to brick another card ;-;

Why don't you try restoring @pandavova 's flash with the custom ntrboot_flasher? That should unbrick the cart

 

[pandavova]

Here is that .nds file.
(Its a normal .rar)

Will do!

It doesn't. The custom flasher doesn't write the firmware

 

[Yandere-chan]

It doesn't. The custom flasher doesn't write the firmware

Is it possible to make one that does write to the bricked/regular cards?

 

[some1ne]

Wrong. See:

Yes. (or at least it should)

Yes, see this post:

Didn't write, it's still 0 bytes card in GodMode9 and no home menu icon.

Woops, I'm dumb. I had the cart out while restoring flash. Retrying. xD

Erm, not wrong. I've actually tried it. a number of times.

Just because it SHOULD work does not mean that it DOES work

Oh well, that's a shame then.

Did you dump you flash after restoring it? Does it match the backup.bin?
