Hacking Some FAQ For The New 3.0 BETA Update

[Intronaut]

Hi.

Can I use the NAND.bin generated in the SysNAND backup as an emuNAND.bin?

 

[andzalot55]

For the. Cia unwrap issue, where in the settings do igoto format my sysNAND?

Question: To update GW 3.0->3.0.1... I need just replacing the launcher.dat, or I need to run de exploit again?
I must run the exploit online (via go.gateway-3ds) or can I do it offline (android local conexion) ?

Just replace the launcher.dat file and it should work.

Ah, so I was right about it being the 9.2. Actually, the downgrade takes you to 4.2 by default. Technically, that's before the Acekard 2i and many other old DS cards were banned, so, if you have one of those laying around, you should be able to install the DS exploit with it for offline use. If not, there's actually an Android app now. So, you could use a wifi media sharing device, portable wifi router, etc. to run the exploit offline now as well.




I think the only people who can't get to a browser are people with a Japanese N3DS on 8.1. Since the N3DS exploit isn't out for anyone, why worry about it? Even if you could get to the web browser, you'd still be royally screwed. There's a firewall on the Japanese version of the browser that locks it so it can only browse a few kid-friendly sites. You have to purchase an eshop download to unlock it. The logic behind this being kids don't usually have access to credit cards. So if you could bring the browser up, it probably still wouldn't go to the site.

The browser exploit probably isn't going to work on an N3DS anyway. I have the Australian N3DS. I can get to the browser. I can take it to the site. It still doesn't work (and the Breakout game doesn't seem to work, either). So, it's not like you're missing much. It's possible Gateway just deliberately left out a payload. However, the N3DS browser is very different from the standard 3DS browser. So it may not work with any browser payload for all we know.

Still, you've seen the video, right? There has to be some way they got it on there. I believe the entire reason they didn't release the Mii QR trick with 3.0.0 is because it would have let N3DS owners try it out, and as they've said, they don't feel the N3DS support is ready yet. Until they release it, you have no reason to panic and assume that you're screwed. People got all worked up over 4 letters being absent from a video, and we know how that turned out.

The Mii exploit is not ready because after you use it the Mii system breaks. I also heard it was bricking EUR consoles so thats maybe why they want to wait and fix the bugs. We would be really fucked if we bricked our systems since there is no hard mod yet for NEW models. Also the nand is 4gb how there going to backup it up to a FAT32 microsd card is a problem to maybe by wifi?

Well, if it's not a Japanese N3DS, it's not the 8.1 that's the problem. Old 3DS 8.1 has a browser. I just injected my 8.1 EmuNAND back to double check. You either need to delete the update from the SD card (if that's where it is, we seem to have conflicting stories on that), or format system memory. If you have to do the latter, set both Spotpass settings to no before you configure wifi, that should keep you from getting any update notifications.



Well that's odd. Certainly leads me to believe the 4.2 was a mistake (an interesting one nonetheless). Unfortunately, 4.4 is the firmware that killed the AK2i. If you had a US unit, you would have been in luck. Oh well, at least you got a free (and completely reversible) downgrade.



OK, nvm the previous suggestion. Yes, the downgrade doesn't check for the card. It does check for the presence of a NAND backup though (which you can also do without a card). Which is probably a good thing (it wouldn't be reversible without it). Only the Gateway and Classic Modes check for the card. And you can go into Classic Mode on 4.x without the card. You can even setup EmuNAND for use in Classic Mode. Though you'll have to be careful how far you upgrade it, assuming it can be in Classic Mode (never tried it).

Oh ok. My problem is that I have no experience with emunand.. sysnand.. ive never backed up anything or done anything like that. I want to get my feet wet and do something without doing damage to my system... and i also want to do it slowly.. step by step so I know where the point of no return is and how to go back to my original set up.

Someone told me that downgrading was a useless thing to do without a cart. So?

I HAVE A QUESTION! How do you play roms online with the new Gateway 3.0 ULTRA? I need help

 

[gregory2590]

Why am I still seeing "An error has occured" after updating? I'm trying to play DS roms. Not 3DS. It's on fat32 and formatted etc.

What kind of tiny sd do you have? Delete a game or sth

A 4GB regular SD memory card.

 

[2Hack]

A 4GB regular SD memory card.

Why not delete something? Like a game or sth. The launcher file is only 4mb.
You can't run the downgrade without it anyways

If Nintendo doesnt come out with the regular new 3ds, I am returning the 3ds XL I got here at Best Buy and never getting Nintendo stuff here in North America.

Hi.

Can I use the NAND.bin generated in the SysNAND backup as an emuNAND.bin?

Certainly, just inject your backed up NAND.BIN with EmuNAND Tool. There's really no difference byte-wise between SysNAND and EmuNAND, only where they are being stored. OK, I admit I've not done a raw copy of the partition using Win32 Disk Imager, or dd in Linux. However, I have done a "Format EmuNAND" and "Dump NAND" back to back, then performed an fc/b between the NAND.BIN and the backup generated by EmuNAND Tool. No differences. So for all practical intents and purposes, at least as long as you're using EmuNAND Tool to backup your EmuNANDs, a NAND is a NAND. But be careful about using the NAND restorer (d-pad up while selecting Downgrade). For one thing, it can restore a 9.4 EmuNAND (which will kill your exploit). For another, I bricked a unit with it. I've been unable to find any reason why it would fail. Adding to the confusion, I now have confirmation it worked for someone else. The only two things it could be is either the 3DS blacklists the old profile when you system format, or I just have very bad luck. I need to get this figured out. Because when the N3DS exploit hits, I want to create the 9.2 update using UpdateCDN in EmuNAND then restore it to SysNAND (since it can't go down to 4.5, might as well take it up to 9.2). But I need to be damn sure it's not going to brick my N3DS.

Why am I still seeing "An error has occured" after updating? I'm trying to play DS roms. Not 3DS. It's on fat32 and formatted etc.

Do you mean downgrading? And which DS card are you trying to use? Many of them are still banned on 4.5, so, if you have a European unit that didn't get downgraded to 4.2, or you used a game to take it back up to 4.5, something like the Acekard 2i still isn't going to work. Also, I've tested that CIA that's supposed to unban them (and yes, I made sure I used a card without an EmuNAND on it). It didn't do jack. Now if you're trying to use the blue card after downgrading and it's giving you that, it may be defective. My suggestion would be to just get a DSTwo if you're wanting to play DS games. It's hands down the best DS card made.

Oh ok. My problem is that I have no experience with emunand.. sysnand.. ive never backed up anything or done anything like that. I want to get my feet wet and do something without doing damage to my system... and i also want to do it slowly.. step by step so I know where the point of no return is and how to go back to my original set up.

The only point of no return is if you brick the device (and even then, with some soldering, you can restore the NAND using an SD card reader). As long as you have your NAND dumped. Most of this stuff is optional. As long as you have a card with ROMs inserted into the red card, after selecting Gateway mode (it will ask to update the card the first time, just accept, and then select Gateway mode again), you should be able to hit select to bring up a menu, pick a game, hit A, and from that point it acts like a real game cart. Just make sure you exit with the home button and close it to ensure it saves.

Now for the optional stuff. First, do a NAND dump. Because as I said, as long as you have that, even if you brick your device, it can be fixed. Then backup everything on the internal card up. Then you can format EmuNAND if you want to. Afterwards, boot into Gateway mode and go into System Settings. If everything went right there should be a "GW3D" in the version. Without backing out, go to the update option (backing out kicks you back to SysNAND, so, always look for the "GW3D" before selecting the update option). Now you should have an EmuNAND on 9.4. Before turning it back on, copy the card's original contents back over, including the NAND dump (delete the new "Nintendo 3DS" folder that was created before copying the old one back). Now if you're planning to downgrade, also copy the "gateway.dg" file over to the card before putting it back in the 3DS. Turn the system back on, go into Gateway mode, System Settings and verify it's on 9.4. If all went well, now you should be able to download from the e-shop again. You might want to backup your EmuNAND using EmuNAND Tool at this point. If a future update is incompatible with the launcher, you can restore your 9.4. Once you've made sure your EmuNAND is working good, if you want to downgrade, go ahead, but boot into Gateway mode and turn the wifi off afterward if you want to avoid getting an update message (the downgraded firmware needs both of its Spotpass settings changed to no). Now that you're on 4.x, you should be able to install the DS Profile exploit with the blue card (or any other DS card that isn't banned). Having your SysNAND on 4.x keeps your CIAs from getting re-wrapped. You might also want to unlink, but, pending further research, I'd hold off on that. If you try to restore a dump after doing a system format, it may brick your console (one of mine got bricked, still trying to establish whether it was the unlink, or I just got unlucky).

If you haven't unlinked, you can apparently safely go back to your previous firmware version by holding the d-pad up while selecting the Downgrade option. It will flash back the NAND.BIN that's dumped on the card. It seems fairly safe, I went back to 9.2 a couple of times on my Zelda unit (once because I didn't shut wifi off after downgrading and got the update notice, and a second time because I forgot to dump 4.2 before updating to 4.5 via SMT4). Still, as I said, I do have a brick, and until I have time to do some soldering, I won't be able to find out what caused it. When I'm able to dump my bricked NAND, I'll find out if some of the bytes aren't right, or it actually refused to run a perfectly good dump.

I HAVE A QUESTION! How do you play roms online with the new Gateway 3.0 ULTRA? I need help

The same way you did on 2.7 Omega. OK, guess that's not very helpful. So, search for something called "Gateway ROM Patcher". Make a backup copy of your original ROMs, then use it to add valid headers and chip IDs to your ROMs (if you don't have any, hit the "use a public one" option). Then rename the extension on the fixed ROMs from .3ds to .3dz to enable online play.

That depends on your definition of useless I guess. Classic mode will boot on 4.x. So, if you want to run an import game, you can. I suppose you could also try the CFW for 4.5. It can't run all the games like the Gateway can, but there are a good number of firmware-spoofed CIAs out there that you can install and run with it.

I really appreciate this. I dont have a red card or even a blue card at the moment... So ill have to wait. But this is still GREAT information. Im pasting this to a notepad.

From the comments I've read, it does work. It cannot be downgraded for the same reason the N3DS won't be able to -- there's no software wifi switch in 4.5. They can go no lower than 8.1. You're never going to be able to downgrade a 2DS or N3DS to an unmodified 4.5. Maybe they'll come up with CFW/MFW that adds the soft switch in a few years.

[MikeyTaylorGaming]

Just a quickie, can the latest lancher.dat be used with any firmware then? It's not limited to just 4.1-4.5 or 9.2 right? I've been waiting a year for this update to Gateway so I've never learned a thing about it along the way hahaha cheers
