Hacking N3ds 10.3 EMUNAND testing

[urherenow]

He's launching rxmode. That means it doesn't matter what firmware he has, it's launching the 9.5 native firm from the SD. That's how rxtools emunand works. But how is 9.5 native firm able to deal with the 10.3 modules in the nand?

 

[Aroth]

NATIVE_FIRM runs entirely separately. You can update it in emuNAND all day, every day. What matters is the NATIVE_FIRM used to launch into emuNAND, because that's the one that's going to get used.

Um I might have misunderstood what you said originally, but it sounds like you are implying that even if we somehow installed an updated native_firm and didnt brick our emunand it wouldnt matter because the system is effectively using the 9.0 (or 9.2) one we booted from in sysnand? So games would still read the kernel as being outdated?

That's what I thought. So if he somehow got a 10.3 native firm in the emunand it would be launching said native firm which would allow new games to run?

Can system titles be crytofixed?

No, I'm saying there's two entirely separate things:

1. The NATIVE_FIRM/firmware.bin used to launch into emuNAND. This is what will be running as NATIVE_FIRM in emuNAND.
2. The NATIVE_FIRM title installed in emuNAND. This is where title versioning information is pulled from. firm0/firm1 partitions are effectively not used because booting into emuNAND is treated as a warm boot anyway.

That's the extent of my knowledge about firmlaunch at least.

I'll rewrite this to try to make sense to it just for the glory of the sun (bold are my notes):

Alright for all of you guys who have been asking for replies: sorry I was overwhelmed by the amount of request and I would rather have given out proof but I wanted to push the videos out quicker to have something to prove it.
1- I had a emunand backup made with emunand9tool (I guess it's a sysnand backup?)
2- I restored nand backup to emunand (I guess he restored sysnand backup to emunand?)
2.5- I then rebooted to check if my games have returned sadly they didn't
3- Then I went back to emunand9 tool then restored the emunand backup when I then went into emunand and a kitten crawled over my system settings launching I realized it was 10.3 rxtools mode.(Magic and things. I do not believe anything of this point)
The downgrade of my 3ds getting got stuck at the 10 seconds screen and I forced reboot after a half hour of waiting. (So looks like a half-downgrade?)

After a good 15 minutes of reading that's the very far I can reach with my english. Looks like a half downgrade did accidental things with emunand9tool. Still I can't understand how that made dbz cart work. Still fishy. lol'd at the kitten.

Use real rxMode launcher and a fwspoofed .3ds on a Sky3DS.

You can't boot a modded rom on a sky.

No. rxtools loads 9.5 native_firm. period. Just like on a 10.3 o3ds emunand, it's loading the 9.9 native_firm.

So updating native_firm in emunand wouldn't have any real effect then beyond basic compatibility issues with some system titles? As far as exheader kernel checks go, is it checking based on the installed native_firm title or the firmware.bin used to launch emunand?

I'm not 100% sure, but AFAIK memory is what is checked against, not the title versioning info in the database; don't quote me on it, though. Updating NATIVE_FIRM in emuNAND should do nothing observable whatsoever.

You can't boot a modded rom on a sky.

If you have signpatch, I think you can, but you have to edit some stuff on the flashcard side to make it work.

So what exactly causes the blackscreen on update then?

I'm guessing its installing a system title that actually requires the 9.6+ native firm?

Gonna guess this would be the homemenu.

The only one who knows how this happened is the kitten, so if OP isn't going to let the kitten do the talking I'm out of here.

>_> can someone tell me how to use 3dnus to download an entire update pack?

 

[TR_mahmutpek]

So, we didnt had anything...
Please dont troll with bluemooncard.

You have to use something based on make_cdn_cia, it's a python script IIRC

Please dont troll with bluemooncard.

This should be your signature.

Maybe, maybe not.

It did get me thinking so I am gonna try some things of my own and report back. I won't be able to get a full update working, but I MIGHT just be able to get enough of one working to get around the eshop problem and problems with retail carts.

I found it.

FW version in title id, region in verison number.

If anyone is wondering, I suspect we can actually safely install the entire update package minus the homemenu. I suspect the blackscreen is caused by the homemenu derping out when it tries to make calls to native_firm that the old 9.5 one we load from firmware.bin can't respond to.

Edit:

specifically I have seen people talk about installing everything but menu/mint/tiger/mset and I know from personal experience that tiger and mint will not cause problems, and i doubt mset would either since we can downgrade it with no problem.

I am interested in this XD tell more XD

The op was a bust. Not 100% sure if he was a troll or just confused.

I am planning on taking your idea and maybe going a step further.

 

[peteruk]

been following the thread with interest @Aroth

i think you should create a new thread to detail the progress you make with your theory you have detailed above, i think your defo onto something

 

[Ninoh-FOX]

photo really does not prove anything, that's something you can also do either, I'm waiting to see what my MP said.
