R4i Upgrade v 1.4 (www.r4-v.com)

[ghost]

I've used the new rewritten NDS Ntrboot flasher on my DS Lite. The card gets recognized as part of the R4iSDHC family, but when I try to flash the FIRM (I use the Boot9strap_ntr.firm) it returns a "Failed to inject FIRM!" error.

Here's the debug.log from the flashcart's microSD card, ~~here's the dump I got from the "Dump flash" option,~~ here's the kernel for this flashcart, here's the dump I got via twopassdump and here's the dump I got from GodMode9

!!NOTE!!: The flashcart can't actually be used in a 3DS since it's blocked. I put it in my 3DS only because my DS Lite sometimes takes a lot of tries to read a card.

For me, seems like a pure clone of R4i-SDHC cards yep, but something in this cart looks weird to me...

The chip (back) is like R4i-SDHC cards no doubt. But the front part does not look like at all like a R4i-SDHC card...

For this, might be some instruction change. Try DSTT and see if the result is good.

@ShadixAced if it's a clone, then why can't the ntr flasher inject the FIRM?

[BellezaEmporium]

Maybe because the chip does not recognise them, or might have been changed by the R4-V team, which looks weird to me.

[BellezaEmporium]

Or maybe it's a NOR problem ? You haven't done a GM9 / D9 flash dump though

[ghost]

@ShadixAced I can't, I don't have a modded 3DS. But I did do a dump via the dump option in the new NDS ntrboot flasher

[BellezaEmporium]

Oh yes my bad. Did you try DSTT ?

[ghost]

@ShadixAced it only recognizes it as a R4 SDHC

[BellezaEmporium]

Okay. That's weird considering that he was recognized. Do not know if the NDS file work correctly. The flash might protect himself from flashing or might be a read issue.

[ghost]

@ShadixAced I posted the log file too

[BellezaEmporium]

Saw it, it is a NOR issue, that it does not end or start by FF.

[jason0597]

@ShadixAced I did try my best to make it so that there is minimal interference from other factors like kernel, sd init, fat mount etc. However I cannot guarantee that having the kernel run and do it’s thing before running the nds flasher, won’t affect it at all

[BellezaEmporium]

@jason0597 At least I've saw you did a great work, but yep, might be one part of your code that might have interfered with @zacchi4k 's flashcart.

@zacchi4k Try to dump your cart, and @jason0597 if you know a lot about flashcart updater or how the NOR works, well will be a good source.

unfortunately i'm not that experienced with how the r4isdhc works, or in general arm and arm assembly

[pixel-stuck]

This looks very much like a DSTT clone. Run the DSTT option and send us the log please

Also, can you get us the numbers on the chip? It appears they burned some of them off, but something might end up being useful

[ghost]

@ShadixAced I did already dump my flashcart with the dump option in the flasher, but now I did a dump with dsflashcartdump @dark-samus here's the log.

Here are the labels on the chips:

I put a black rectangle where they put something on the chip, although it LOOKS like there wasn't actually anything written below

!NOTE! I did use a DSi for this, since my DS Lite doesn't want to read this flashcart anymore for some reason

[pixel-stuck]

Indeed, this seems to be a DSTT clone. It gets what appears to be a valid flash chip ID, but likely we just don't support that flashchip currently

[ghost]

@dark-samus I followed this guide to install YSMenu, and indeed, this cart needs to use the "DSTTi-Clone" folder, so yeah... How hard would it be to add support?

[pixel-stuck]

Well, first things first, we needed to know what flashchip it is. The text you provided from the big chip gave me that. Punching some of the text into Google got me a datasheet, which in turn gives me the flash commands. From there it's figuring a few things out. Block size, chip ID (which you provided with the log), among some other things. After that it's just doing the work of integrating it into the DSTT code

[pixel-stuck]

Also; lol, the dump from dsflashcart dump is literally all zeros...

[ghost]

@dark-samus is there some way I could help you with the other things needed to know?

[pixel-stuck]

@zacchi4k just try this build for me. This one will only read the flash, it won't restore or inject ntrboot ntrboot_flasher.zip

[jason0597]

@dark-samus i don't think they have a hacked 3ds

[ghost]

@dark-samus I don't have a modded 3DS, so I can only use .nds flashers. Sorry :/

[pixel-stuck]

ah, well, I can compile a DS version :)

[pixel-stuck]

@jason0597 trying to compile your version I'm getting an error, which makes perfect sense, I'm just not sure how it made it to git or if I'm missing something here...

ntrboot_flasher_nds/source/menu.cpp:122:4: error: 'breakCondition' was not declared in this scope breakCondition = true;

EDIT: looks like this commit just forgot to remove it: https://github.com/jason0597/ntrboot_flasher_nds/commit/7c5a8bf967f1851d2d99d6542a637db95c2b8ad3 probably just a return, huh?

[pixel-stuck]

@zacchi4k whenever you're ready... Do NOT attempt to restore the flash or inject ntrboot yet, this should just read flash.

ntrboot_flasher_nds.zip

[jason0597]

@dark-samus ah yes that was a bad commit, i'll fix it now silly mistake

[pixel-stuck]

@jason0597 I usually run all my commits through a "make" before pushing to git, catches a lot of silly mistakes ;)

[jason0597]

@dark-samus how did you get your binary to be so small? it's 50kb smaller than the one i make
