I've been trying to downgrade a n3ds for about 2 hours now and no luck. It never finds the .cia files for the downgrade... from some looking through of the thread on gbatemp it appears to be a pretty common issue with people on a n3ds.

Strange. What's the exact error message it returns? You should have the .cia files inside a folder named "updates" on your sd card.

Yeah, I keep checking and rechecking thinking this is the issue. It's at e:\updates\xxxxx.cia. 9.2-20U, there are 102 files and the MD5 hash checked with what is on gbatemp, so that all looks to be good. I've tried unzipping using the windows default zip tools and 7zip and neither have helped.

I'm on a N3DS XL, 10.3-28 and using both Ironhax and MenuHax to try and get it to work. Some people on GBATemp think that by opening up certain apps is what helped them but I think it's more just stupid coincidence that the last thing they tried was just the last thing they tried before it decided to just work for X reason.

edit: Few other info, I don't get the 8 checks up at the top of the screen when I launch the sysupdater. It just lists what version it is and then what buttons to update/downgrade/exit. The red text isn't a warning to not update a N3DS, but "IMPORTANT: Don't run this in sysNAND Gateway mode or it will brick!"

The downgrader isn't the most stable for initially launching. For me it took a good hour of trying random things to launch it to get it to work. In the end what worked for me was booting in using menuhax, going to ftpbrony, hitting B twice right when it loaded and then loading the downgrader.

Are you getting any error message at all or? I did get "failed to retrieve cia list in .cpp" or something along those lines once. Just required more tries.

The 8 checks were removed from the safer downgrade version. It's really obnoxious because it's hard to tell if it crashed or not without just sitting and being patient and wasting time.

Also one thing I forgot to add to the op that you probably should:

After you have CFW setup you should use the tubehax dns servers on your connection. This will block all traffic to Nintendo including updates, eshop, online, etc but it stops your system from trying to download updates. It's handy for Nu3DS since emunand is stuck on 9.5.

Switching gears. I'm getting a WiiU this week, and since I sold my xbone I don't have a blu-ray player anymore. If I hack the vWii portion of the WiiU, is it possible to install something to play back Blu Ray discs?

I could be completely wrong, but I think blu-ray players have a special kind of laser that operates on a different wavelength than CD/DVD. So like the red laser in a CD/DVD player is a broader wavelength but the blue laser in a blu-ray player (hence the name) is a narrow wavelength so it reads the same amount of data (or more maybe) in a smaller space at one time, so more data can be packed onto the same size disc. Please correct me if this wrong. (You might also be talking about modifying the hardware in which case I really have no idea)

You are correct here. However, I'm pretty sure the WiiU has a Blu Ray drive and uses Blu Ray discs, but because of licensing fees they can't play movies out of the box.

No. vWii does not have access to the blu ray portion of the drive at all. Think of vWii as literally shoving a Wii inside a Wii U with very minor modifications to fit the newer security.

I have a new3ds. If I downgrade to 9.2 can I somehow run a .cia backup of a 3ds game I own directly from the sd card without the need for a flashcart? I'd like to be able to have monster hunter on my sd card and smash in my cartridge slot but I bought physical copies of both games, and I don't really want to risk shelling out 90 bucks on one of these shady sky3ds websites.

Also once I have cfw, I can still use the shop and play online with people on current official firmware, right?

If you're talking about Monster Hunter 4 Ultimate in particular, you're in luck, because there are "legit" CIAs of it available, meaning ones that are properly signed by Nintendo and will run without disabled signature checks (so you don't need to be on FW 9.2).
You can install legit CIAs on Firmwares up to 10.3 currently.

The decryption keys for the 9.6+ FW updates on the n3DS aren't cracked yet, so upgrading will just lead to an emuNAND softbrick. Not really a big deal since you can just re-inject your emuNAND.bin and be set, but annoying. Fortunately, there's a way to still access the eshop and play online with people with official FW versions even on 9.5.

You can absolutely grab a .cia of a game you own without the need for a flashcart, though I'd just download them from a certain 3DS ISO site which has .cia files for basically every 3DS game rather than learning how to rip one from your card yourself.

But yeah once you have CFW it's really as simple as putting the .cia anywhere on your 3DS, running FBI or Big Blue Menu to install the .cia and then playing it like a normal game. It'll go online no problem, and it's entirely undetectable.

However, it's a bit of a pain in the rear end to get the eshop to work on 9.5. Basically, once you downgrade you have to format sysNAND (and then reinstall FBI with PastaCFW), boot to emuNAND, update to 9.5 with sysUpdater, run freemultipatcher, install the 9.5 NVER, backup your Nintendo 3DS folder and your emuNAND.bin, format emuNAND, erase any themes on your sysNAND including menuhax, re-inject your emuNAND.bin and your Nintendo 3DS folder that you backed up, re-install NVER and FreeMultiPatcher, then link your NNID in emuNAND system settings.

Once you figure out what you need to do it's actually quite simple, if still pretty annoying.

There's keys used to encrypt the underlying firmware of the system however with 9.6 Nintendo changed how it worked and patched a gaping hole that was used to get previous keys but only on Nu3DS. Because of this it is impossible to run firmware >9.5 and due to not being able to decrypt software cannot run games that requires >9.5.

There is however ways around this using "cryptofixed" packages. For the time being it's not the end of the world. If Gateway is in fact able to get their card to work on 10.3 then it will likely bring about emunand support which will trickle down to CFW packages. With CFW it's a game of cat and mouse however Nintendo hasn't bothered updating the crypto on O3DS so it has been immune. This is why I have two systems personally... well 3 now.. ok 4 but getting rid of the o3dsxl. Having 1 system for legit is handy for those games you really, really want to play and can just purchase a title. I have a hacked nuXL as well now that I'm getting emulators setup via cia and will use it more for Japanese roms and the various game hacks that float around. I also use it for save management as there's a lot of tools you can use to take advantage of system's saves.

Last one is a 2DS which I love the form factor so I just got it because why not. It's also clear plastic and that rules.

Waiting on hacks to bring a newer game around/system can take a considerable amount of time. When 6.x came about there was some key change nonsense and it left users out in the dark for months on end. You'll see posts on the internet poking fun at Gateway when they say Coming Soon!...®

No, that's not the case. Most games don't require >9.5, and those that do there are generally cryptofixed versions floating around. You can even do it yourself quite easily.

PocketSNES works better and faster for some games too. There is no one stop solution currently.

The n3DS uses a microSD card and can just publish itself as a device on your network that you can log into from your computer to drag/drop stuff onto or off of the SD card that's in it.

The transfer speed is loving abysmal, though.

Typically setting up emunand and the sort will nuke all your saves and might update the encryption on your system so the saves won't be usable.

You might have menuhax on both your sysnand and emunand. You'll have to figure out how to not hold the trigger key for sysnand then hold it for emunand. Then in emunand change themes to wipe menuhax from it.

You'll probably want to add something in between so you can hold the trigger, maybe autoboot to the homebrew launcher instead for now.

After I install rxtools (and have it boot by default) I keep having menuhax flip the gently caress out when it goes to emunand and get stuck on a red screen. :\

Actually better way:

1) Uninstall menuhax entirely
2) Split your sysnand from emunand by powering your 3ds on with the sd card ejected and format the system
3) Put card back in
4) Reinstall menuhax on sysnand
5) Should be split, no hax installed on emunand
