Homebrew Safe NAND Manager - Safely dump or restore your DSi NAND!

RocketRobz · Dec 3, 2020

Previous versions of fwTool have allowed users to restore NAND backups whenever they wanted.
Starting with 2.0, the NAND restore option has been removed to prevent the NAND chip from wearing down, due to full restores.

If you've been waiting for a safe way to restore your NAND, then I have just the tool to do so!

Introducing, Safe NAND Manager!
It's an improved version of @zoogie's dumpTool, which alongside doing safe NAND backups, adds an option to safely restore the NAND!
Unlike fwTool, it works by only writing the modified sectors of the NAND file, into the NAND chip, as the sectors from the file and the chip are compared before writing.

This tool can be used to safely uninstall Unlaunch, by using a NAND backup that was made before installing Unlaunch.

Really nice. Sadly my test DSi is no more.

@Robz8
Kudos!
I know it's not much to say "Thank you!" on a forum – but it's all I can do. Really appreciate your continuous efforts.

So…

Thank you!

Thanks @Robz8 !

Thanks Rob, that's something the Dsi needed for a long time.
Does it also check if the CID and ConsoleID of the console are the same of the backup?
Also also if I read that correctly the dump comes with the no$ footer attached, so you need to remove that before doing an hardware flashing, right?

Wow nice job @Robz8 !
The final straw would be a custom unlaunch and then the whole DSi is basically owned by you.

Gonna try it during the weekend with my backup. Wanted to get rid of unlaunch for a long time on a particular console but couldn't take the risk.

So, does this make it possible to revert a CFW DSi to stock?

Seems so. Would not be very safe otherwise…

Features:
- Completely open source.
- Lots of checks, including verifying the nocash footer will decrypt the outputed NAND. Low battery and insufficient SD space are also checked.
- Project has a permissive license, and more importantly, its dev is permissive. I don't care what's done with this post-release as long as credit is given.
- Simple operation. Just press A to dump, or Y to restore, and watch it go.
- You can cancel the dump in progress. The incomplete nand will be cleaned up.
- A little bit faster than fwTool. Should complete in about 7 minutes. NAND restore may take longer.

If you flash an image created before installing unlaunch.

That bit of the readme is unchanged from zoogie's project, but I gave a rapid look at the changes and, as far as my noob programming skills can tell me, it seems to be checking both of those =D

does it also check the nand dimension? /s

Okay, but can you create a NAND backup without installing unlaunch? (And without doing a hardmod?)

Yeah, dumpTool (or this) both work directly from Memory Pit, on dsi.cfw.guide it has you make the NAND backup before installing Unlaunch: https://dsi.cfw.guide/dumping-nand

Even if you only had backups with Unlaunch you could also uninstall it in no$gba, then test and make sure it still works there and if it does then restore that as if it works in no$gba it should work on console.

Okay, but that page suggests launching dumpTool from TWiLight Menu. Can you launch TWiLight Menu directly from Memory Pit..?

Yes, you can.

It's so tricky keeping track of all of these developments. :-/

You still need to install HiyaCFW before you can use TWL Clock Speed in TWiLight Menu, right? Or can you do that from Memory Pit as well?

Yes, it can be done from Memory Pit as well.

Gee. Are the other restrictions listed at https://dsi.cfw.guide/installing-unlaunch still accurate? Or have some of those been bypassed too?

They're still accurate/true.

Time to get an other DSi and try it again.

Thank you for that Motivation,my Friend.

v1.1

What's new?

(@Pk11) Added a warning message before starting a NAND restore.
(@zacchi4k) ConsoleID and CID are now displayed.
(@zacchi4k) A hiyaCFW warning is now shown, when invalid footer is detected.
