Hardware nand flash dump (3ds xl)

[TheBerryBeast]

Yes but they dont sell wifi modules for 3ds xl only 3ds even though i think they have the same connector but havent found any confirmation on that.

Hi all,

I just finished the hardware mod on my 3DS and dumped an image. But how can I verify that it was successful without taking the risk of flashing the image back to the target?

win32diskimager ended with a successful message, 2 different dumps has equal content and file size is always 1.000.341.504 bytes. Opening it with a hex-editor shows "NCSD" at 0x100, a larger area of 0x00 from 0x200-0x012DFF and another lage area of 0x00 from 0x059400-0x23FFFF.

Can somebody confirm that, or has other key values in the image?

BTW: I attached some photos of my solution of the MMC-adapter - perhaps someone find it useful...View attachment 3627 View attachment 3628 View attachment 3629

just dump my new white 3ds xl

same as you but my 2 dump are 988 807 168 bytes ... maybe because im on 4.4 ?

There are size differences, because of different NAND manufacturers.

oki, i ipdated my 4.4 to 4.5 with animal crossing then downgrade to 4.4 without any problem, i guess im good to go with my good dump

ty profi200 for your help on irc

This is great. Read this. However, unless I am wrong, you can only read/write raw without way to get keys. Also, has anyone tried to write an older firmware. Term used loosely, lol. Some devices have efuse be to prevent downgrading. One benefit is to revert to use an exploit. One was patched...there was another but I was told this privately. Cannot say type or details at all. Also when updates are applied, there may be security preventing simple flashing to revert.

Did not see anyone confirming they reverted. A guy was trying to do this with Wii U but was harassed into going private and closing his thread:-(

someone should make a tutorial about this

I agree !
I want to dump mine too but can't open it. I screwdriver succefully open the first 4 screws on the cover, after that I can't unscrew the rest. I almost f*cked them up trying to unscrew them.
I have this tool

Can someone recommand me one tool? and where to find it ( Radio shake, Walmart,Home depot ....) ?

Well, I guess it would be nice If someone made a video tutorial !

I confirmed a downgrade from 6.1 to 4.5. Spzjulien a few posts up confirmed a downgrade from 4.5 to 4.4.

For some extra safety I recommend to also dump the upgraded firmware version before you attempt a downgrade such that it is possible to revert that downgrade.. Just in case Nintendo found some trick to detect and prevent execution of an older firmware version (e.g., by utilizing the presumed efuses contained in the SoC package).

 

[how_do_i_do_that]

Requires a soldering iron and skills to use a soldering iron.

I just wish that we could exploit the injection of CFW into the update partition of ROMs without breaking the signature. >.< Because then we could use something like the Gateway to install the firmware update from the ROM to the system. Hopefully a re-signer will be released, like the PS3/PSP have, so we can make use of such an awesome exploit.

The PS3... had its master private key revealed, it's not that hard for them to re-sign things now...

although, this is only if you have a dump made previously, but without this, it is not possible (yet) to downgrade your 3ds, right?
i don't know if anyone has any firmware update 'files', i doubt it, but, from comparing a dump from 6.1 to 4.5, amongst many people, it might be possible to convert a 6.1 dump to 4.5?

maybe you could copy over someone else's 4.5 files to your own dump, making it 4.5...? is each system file encrypted to your own 3ds? if not, then it sounds possible.

yeah u can revert your 3ds from your original fisrt dump ... if u got brand new 3ds with 5.1 or more .... no luck Can't downgrade

but if like me u buy 4.4 3ds then u can do what u want, update play new game then downgarde
allway backup firmware before downgrate, but so easy to do ...

you are saying that you cannot downgrade if you update past 5.1? why is that?

but what i want to know is, what will have to happen/be found so that i might be able to convert a firmware to a different version, by replacing files?
like, taking version 4.5 files from your 3ds and put them into my 6.1 firmware dump, making my dump into 4.5.
as far as i know, the firmware dump cannot be explored/opened etc? and this is because it is encrypted to each unique 3ds console?

Can anyone confirm that you can downgrade from 6.2 firmware because i am going to send my 3ds for repair after a nand dump and they will probably update to this version.

update to 6.2 1hours ago dump 6.2
then downgrade to 4.5 and reflash 6.2 dump to try it then downgrade again

so yes no problem at all

 

[TheBerryBeast]

My wifi doesnt work cannot update.

 

[pasc]

So like... you CAN already dump and write your firmware back ?

Since I don't feel like reading all of this here:

Is there a link to a instruction on how to do this ?

(What is that program loaded in this screenshot anyways?)
