I thought the others made it clear that the only reason this works is because we patched NIM to use HTTP instead of HTTPS and pointed it to our servers...

Thanks a lot for clearifying. #113 said "Except the initial 3DS connection ..." and that made me a little confused.

Also, what about man-in-middle attack to hijack this HTTPS connection? I know this requires a valid SSL cert.

Is there any other difficulties besides the requirement for valid cert, for example, 3DS will force check the exact type of the cert like the latest browsers?

Thanks!

That's a pity...

Is the way that Gateway create the downgrade payload known by the scene? It is already verified as a safe and easy way to manipulate sysnand.

It should be possible to create similiar payload that let people flash to 9.2.0-20 sysnand.

please help me, I really want to play some games already.


I don't intend to be rude, but if you attempt this without knowing what you're doing you may brick your 3DS and never be able to play games on it ever.

If you want to do the update, all of the information needed is in this thread and the NTR 2.1 thread.

I would strongly advise making a backup of your sysnand using gateway's launcher if you have not already before doing anything further.

Dunno about gateway but there's many different ways of upgrading/downgrading. All you really need is a way to install the common tickets and the titles. CIA installing is one way (cia includes ticket and title). This is another. I perfer this method because it's also the Nintendo official way of upgrading the firmware so if we (the scene) overlooked something, it doesn't matter.

Got it. Thanks!

I have some further questions.

Is is possible to upgrade New 3DS XL from 9.0.0-20U to 9.2.0-20U, since 9.2.0-20U was never officially released for New 3DS XL?

About region swapping, I heard that securinfo_? is the key for determining a 3DS console's region.

What happens when all titles are replaced by another region's titles, but securinfo_? keeps the previous region?

Another question is, I guess some titles are exclusive to certain regions.

For example, if title A is exclusive for USA region and does not exist in JPN region, is it possible to completely remove this title using our customized response xml file, when we are going to change the 3DS console from USA to JPN?

Thank you very much!

Well, I don't understand what you're asking me. Those two NTR Threads don't say anything on how to enable it. Oishikatta

[Feature] Debugger: Debugger feature is normally disabled, you can use NTR CFW Menu to enable it, or put an empty file named 'debug.flag' on SD card to enable it automatically.

CFW Menu. Press X+Y in games or Home Menu will show the NTR CFW Menu, to take screenshots or interact with plugins.

Yes, I have 9.2.0-20U on my N3DS. If you install all the USA titles, it doesn't delete the JAP titles. If you swap regions before installing the titles however, it's a brick. That's why you shouldn't attempt it unless you know what you're doing.

Oooh, look at what was just released,
https://github.com/profi200/sysUpdater


Ok it looks like what this is used for is to update firmware using .cia files downloaded with UpdateCDN or 3DNUS. The cia files need to be located on the SD card in a /updates folder. Not brave enough to try without a hard mod.

Got it. Generally, it seems that attempting to manipulate sysnand is always difficult and dangerous... Thank you very much!
