Hacking Bad Flash R4-SDHC

[AnKi]

Hi guys, I am new here and I need some help if someone could please lend me a hand

I was going to upgrade my R4 for using with the latest upgrade of 3DS, but I turned off it before it ends and now I have a blank cart, it don't show anything when booting up

I've heard that a fix could be done if you have an exactly same flashcart, then loading the flashing app, and when is loaded swap the good cart with the bad one, and continue flashing should fix it.
But I don't have another R4-sdhc, everything I have is a normal R4, only reads non-HC SD cards, and a SuperCard MiniSD.
At now I tried Everything I could done, I've tried the swap card method with the R4 and the R4sdhc with no luck because the flashcard freezes once is taken out.
I've tried to make a mini download station thanks to this beautiful homebrew called WMB Host, so I've inserted the R4-sdhc and loaded the flashing app via DS-Download, but no luck either.
(For WMB_Host you have to put the target file as "test.nds" (in this case was the flasher) on the root of your fc and then run the WMB)Trying to load the flasher via the SuperCard SD don't work.

I'm thinking that the only way to recover may be getting another one and using the swap card method, but anyway I want to try something else, i don't wanna give up yet ^^"

The last thing that I was thinking was If I could get dump of the R4sdhc, yes, I mean a dump from it talking as a DS-Cart and not as a flashcard, because it has some DS code inside to simulate being a real cartrdigue as shown on the DS Menu. (Not as the old R4 that works in a different way not having to simulate being a cartrigue so I cant use on from it)
It is imposible to find and the only way is if someone could provideme it using some homebrew dumper

I think that if I load it via DS-Download or via the Slot-2 I could boot the R4 and then running the flasher.
I'm almost sure because I've successfully switched from the SuperCard SD Menu to the R4 menu without turning off, doing this: I've put the "R4TF.nds" (File that comes with MoonShell for Softresseting the console), on the root of the SuperCard, and when I've booted it, it worked, and could continue using the R4 menu accessing to the Slot-1 sd card etc etc.

It's my last hope, but now I have to find someone who could provide me a dump from the R4sdhc that is the hard part from this story ^^"

Any suggestions are really apreciated,
I leave some photos of what I actually have

The WMB Host application, I loved it, but it wasn't useful anyway

What shows when is loaded from SuperCard or DS Download

When is loaded from R4 it shows V0.00

Thanks in advance,
AnKi

It doesn't have to be the same flash cart, it can be a different model. I don't know why it's freezing in your case, just want to make sure you know the proper procedure.

1 - Download a firmware update file for the broken cart, put it on the working one.
2 - Start up the working cart, start the update program. Do not tell it to update.
3 - Take working cart out of the DS.
4 - Put broken cart into the same DS.
5 - Now tell it to check/update.

If you can't do this process for some reason and you've tried on multiple DS units, then you'll need another flash cart entirely. Some flash carts just weren't built with unbricking in mind.

... what? Why would anyone ever do this? Seriously I see people do this with other devices all the time. I fixed someones pc before and when I dropped it off she booted it up tested it was working, powered it down and when the windows updates were going on she literally yanked the power cable out the back. Literally, yanked, the, power cable, out the back. No joke.

Why?

@Rydian: I followed all these, It frezes at the point "Erasing", and nothing else happens, I waited long to see if somethings comes up but nope, just freezes.
Funny fact is that I've tested the flashing app on no$gba and it completes entirely, it even passes the "erasing" point xD
(doesn't matter why I've tried it, I just wanted to know what shows when the procedure is done)

@hisagishi: I know, it's a bit confusing but well, accidents happen sometimes when they're not intended to be, I didn't tought It were going to be that harmful, I've learned now I think

because some people don't know any better,they do so by accident or are just plan stupid
this is how most electronic get bricked

Well I think I've come here for help not for learning to do things that I've already know to do,
Everyone can do something wrong. I did it wrong and.. so?, At least I admit it, and I don't think I am "stupid" but well.. think what you want

***
I will say it again, If someone can provide me a Dump file image from a R4-Sdhc please do it. I'm planning to use it for booting the dead one from an alternate way using that.

I don't need anything else or more suggestions about not bricking a device. Thanks Everyone.

The bootloader data is encrypted for flash carts, and nobody has ever successfully created or edited a bootloader update tool (people wanted to for older carts simply to change the icon).

We can't give you something that doesn't exist and won't work, which is why we told you the only-known solutions to your issue.
