Hacking [POC] Removing Update Nag on EmuNAND

[Deleted User]

Does the old emunand backup need to be on the same FW version? I have a backup from 9.2, but not for 9.5 which is what my emunand is currently on. I suppose if this wouldn't work, I could simply create a new emunand, and update it to 9.5 with sysupdater, right?

It doesn't have to be on the same firmware.

Does this work on N3DS

Yes, it worked on mine.

My N3DS was nagging everyday.
Now it's been a week and no nags!
(too bad it doesn't work on the wife...)

Sure is a lot better then the way I had done it. Well done

Well it's made for the N3DS users since they can't update to the lastest firmware, so why not? xD

This worked perfectly for me on my N3DS' 9.5 EmuNAND. I'm looking forward to more of your helpful EmuNAND tips .
I didn't bother with cleaning /titles, as I'm not particularly sure when the nag started appearing as it was so long ago. I just replaced import.db, and the nag was gone.

N3DS 8.1.0-0J is unsupported because it has no XORPAD access at the moment.

So I have started getting the update nag for the last couple of days.. Is there anything i can do if I do not have an old emunand backup ?

Use your nand backup.

What are you guys using to mount and edit the decrypted .bins? I've tried a few different programs and nothing works.

 

[VerseHell]

WinImage.

 

[Darktalon]

Thank you! It worked for me, no more nag! I didn't delete any update files though, so will this keep the nag away permanently until the next update from Nintendo?

 

[VerseHell]

Use the tubehax dns on your emunand and you won't have to worry about that anymore.

It appears RxTools has implemented import.db injection

Nice! Could it be made as a standalone app/cia as Kurt91 suggested:

I wonder if it would be possible to make a .CIA for this. You'd open the app, and there would be two options. One would make a copy of import.db and the other would be for when you get the update nag, and it automatically locates and deletes the update files, as well as swap the import.db file with the copy version.

I only ask for convenience's sake, and that a simple 1-button solution seems much more idiot-proof and you're less likely to get complaints from people who somehow screw things up.

This feature is now part of the nightly build of rxTools (import and inject import.db).

@AlbertoSONIC @d0k3 Eh i have get another method to do so but I haven't tested this. -- since my network stucks.
Original Link: tieba.baidu.com/p/4111242400 WARNING: CHINESE
It is said to delete the following files from the NAND:
In dbs: tmp_i.db, tmp_t.db, import.db.
In title: All those having a extension as "ctx". And remove those Newest APP and TMD and CMD if you know this title update has been fetched.
In tmp: title.tik
Actually this can be done in programatic way. However you would have to scan the folders, and also check the file dates.
Well since TMD have what contents related to it, you can make it deleted more safely. It is recommended to force user to backup the target NAND first, if using this.

Thanks for the pointer! While that would be pretty convenient, I'm unsure if I will add this. This is just not tested enough, and removing that much stuff from the NAND can have unexpected consequences.

Thinking about it, I wonder if there is any way to update-proof a system. In theory, we'd just have to create a write protected dummy file in place of one of those update files. It might block other stuff, though, eShop/CIA installs for example.

It might not work. As what the link tells you, it get contents and place those into the content folder, with their content index as the name.
Also i doubt what if the file creation failed, would it halt?
