Hacking 3DS unbricking progress

[gamesquest1]

I already have that. It's in one of the screenshots. What now?

dont see the csd in the screenshots, but yeah as bkifft said its unlocked but not removed write protect...if you still have trouble....make the wire a little bit shorter

Unbricked! Thanks to both of you!

As you said I loaded the new RPU and used the r command. I took a few tries, but then it worked, see this message:



What are error messages at the bottom? Is that something to be concerned of?

Also what I still don't understand is why the Pi only recognizes the MMC only like 1 of 30 tries. The USB cable is now only 10cm long, which shouldn't be the problem I guess.
Again thank you very much

Likely some sort if interference or a weak solder point somwhere

Glad to hear. And just as the brickophile already stated you either still have a sub optimal HW mod (resoldering the SD/USB cable might already give a huge improvement) or you just happen to live in an EMI interference hotspot (high voltage power lines, radio transmitter, close to a factory running uninsulated old electrical motors, alien mind control beams, etc).

The error message in your pic has to have come from a garbled up reply (the message "everything went fine" from the eMMC to the Pi) , as the CSD write (aka the removal of the write protection) went obviously through. So it's no point of concern.

(Sidenote: thats one of the nice things of the eMMC/SD protocol: every signal transmission is checked using checksums, ensuring that a garbled up transmission fails in a safe way).


Oh and the usual reminder: Step 18, chop chop!

Can this still be the case when the same setup works perfectly for dumping and flashing the NAND on my PC in the same room?

Here you go:

Erotic enough?

gamesquest1: After cutting the USB cable I get 5MB/s writing and reading speed

Yes, as the Pi can't clock down as good as some USB readers. Furthermore the Pi itself is quite the antenna (at least in relation to SD readers).

Well, you have to judge it to be erotic. But this ain't my email account...

Are Units Bricked in the past. not just from flashcarts fixable this way ?? I see a couple for sale here $120 NZ bought off ebay 2 years ago, his description is Unit freezes and hangs on a blue screen of death with random numbers

With near certainty non launcher.dat related bricks are unfixable with the tools (the mystical often quoted single high energy photon wouldn't suffice for the locking).
One could just use them to try and read the eMMC status, but I suspect those bricks to be the result of hardware damage (bad solder, burn out) or filesystem/logic layer damage.

 

[tHciNc]

It happened straight after a firmware update apparently... long ago, thanks for the quick response bkifft

 

[gamesquest1]

if you have them in hand it might be worth you having a look at the csd,pretty sure the bsod, is related to some sort of hardware failure, if it was just a bad flash it would more likely hang on a black screen during boot up instead, even a write protected nand only freezes on a black screen, its only once the nand is completely locked that you get the bsod

i suppose if the nand was completely wiped it might bsod, would probably be interesting to see what the nand dump looks like

 

[tHciNc]

I suppose i might buy it for the sake of it, $120 for a paperweight though lol

He also has another that he says Power light comes on for a second then speaker makes a click sound and shuts off, bought them both off ebay at the same time, its not a definate how it got BSOD, that was from memory from the guy, he did something then it bsod

oh sorry i thought you already had them, tbh $120 seems a bit steep, not familar with the site, but maybe if you can make an offer, just say you want the screen's or something like that, see if you can get it for less

 

[tHciNc]

Its like New Zealands Ebay lol, ill wait till it doesnt sell then make an offer, dont know how he thought he was going to fix it to begin with, and since he has had it 2 years, he mustnt have got far, He must know chances are slim

 

[gamesquest1]

well assuming the screens work ok it would be hand for spares at lease

I searched everything and I have not found a raspberry pi or arduino for sale in Tunisia! t currently there another solution with another system, such as a PC that runs on linux or something else?

You could duplicate the pi work on a laptop with an internal sd reader, Linux, and some heavy reading into that particular sd controller..

is that it is true, as many people told me not you need a raspberry pi, so a laptop that runs on linux and I can unbrick my 3ds, oooooh

well, only if it doesn't use an USB based card reader. And at least in the last five years I've only seen laptops using USB based hardware (even if they are built in) as those are way cheaper and do the job for the enduser (reading and writing SD style media that is) just as good.

If you want to succeed this way you will need a laptop that recognizes SD style card devices as /dev/mmcblk[NUMBER] instead of /dev/sd[letter].

You could also look into abusing a linux style smartphone (android should be easiest to handle), as someone (quite a few pages ago) mentioned that those also use dedicated SD hardware interfaces for their memory cards.

No. I read somewhere that only the RPi has low level sd card access.
