Homebrew RELEASE Open source horizon nand-dumper

[asdfaaasssdddfff]

This is an open source tool which dumps the nand from horizon. (like the reinx-toolbox)
I made this because I dislike that the reinx-toolbox is being kept close-source for no apparent reason since all the information needed to dump the nand from horizon is already public.

It's mostly a direct port of this pegaswitch-script. (github_com/reswitched/pegaswitch/blob/master/usefulscripts/DumpBIS.js)
It will dump boot0+1, prodinfo and the rawnand to the root of the sdcard, automatically splitting the file if on a fat32-sdcard.

Warning: This may or may not result in a corrupted backup, I take no responsibility whatsoever for bricks.
If you want a proper backup use hekate which has proper backup-verification.

If you want a horizon-nand-dumper, the reinx toolbox is probably better than this (idk, I can't look at the source code).

Cool work

Why would we use this? You are not a known dev its probably a brick code

i can vouch for this not being brick code, i just read the source it literally reads directly from the nand into the file...

This is not compiled, so you have to compile it yourself. Meaning you can look at the code, see what its doing and improve it if you wish.

All dev's have to start somewhere.

you were complaining yet you don't even open the attachment do you?
there's no binary provided, and I'm no Switch dev but based on what I saw, it doesn't look like it (whether it's working as intended or not I don't know)

I can also verify the authenticity of the dev and elisezerotwo

 

[EliseZeroTwo]

I can also verify the authenticity of the dev and elisezerotwo

thank you senpai OwO

 

[dragonfromiso]

Im still not using it.

 

[Adran_Marit]

Im still not using it.

No one is forcing you to use it.

Neither is the dev or elisezerotwo

I love how a user with an extremely random username @asdfaaasssdddfff and no other activity posts some script, then another person who also only registered yesterday and also only posted on this thread vouches for it.
This just has attention written all over it, even with the source attached.

 

[palantine]

Good work! As the writer of the reins toolkit dumper I can say you have the right idea here. I was planning to release the source for mine at some point but just been very busy recently. While I would love to have everyone use my stuff I think its great that other people are learning to code and making contributions.

If you ever want to talk to other devs, share ideas and code why don't you consider dropping by the reiswitched discord server and talking to the people on there.

Cheers,

[Draxzelex]

Hmm, now I wonder which one dumps faster: the open-source version or the toolkit?

Even calypso who is one of the Reiswitched discord devs (the one who wrote their dump code) said good work and approves it. That says more than enough for me that it is legit and worth any and all attention it is given

No idea, would be a nice thing to test

Did not know the ReiNX Toolkit is closed-source, that's pretty shitty. Newfound disrespect for that project...

no what's shitty is finding disrespect for the project when they have every intent to release the source for the toolkit.

but that's just my opinion

No need to be brash! I missed that statement. Though, still a bit unnerving to see the release of said project without a proper source accompanying it, even if its being promised at a later date!

Sorry u.u

I understand why they delayed their release though apart from been busy, I doubt they wanted TX to instantly copy it

Look at the code, it's pretty simple, there's nothing suspicious here...
