Can anyone make a list of what files needed to be installed to get each firmware? If anyone knows i downloaded doth 4.5.0-10E and 9.2.0-20E without error and there is in both a folder 2.0.0-2 with different size and files inside. Why that?

Why is easy, you don't need duplicate files. If the file gets updated in later FW, you don't need the older file to install, thats why the .csv loads different files for each update.

An other one question, if i am on fw 7.x and want to go to 9.x i have to install 8.x and 9.x or only 9?

Also, New 3DS models have an extra layer of encryption on FIRM for ARM9.

What will this mean to end users when GW releases 9.2 support? Will homebrew have more limitations?

! WARNING !

As 3DS / XL user - to be clear - non NEW 3DS User, DO NOT INSTALL FILES FOR NEW 3DS!!!

Installing NEW 3DS files will end up having Blackscreen in emuNAND!

Example: (EUR)
00040010 00022D00 Face Rider for 3DS
00040010 20022D00 Face Rider for NEW 3DS

Files for NEW 3DS have a leading 2 inside Unique ID!

The .CSV loads both, 3DS and NEW 3DS FILES.

For FW 9.4.0-20E (3DS/XL) remove thoose files:

When Gateway's Support for NEW 3DS is OUT, leaving out some old 3DS Files might be necessary!

For installing CIA Firmware on 3DS/XL emuNAND:

- Plug in your charger before starting and make Backup first! -

1. Download your desired FW using UpdateCDN.py -EUR/USA/JAP FW-VERSION.CSV
2. Remove all NEW 3DS Files (in EUR starting @ 9.0.0)

To shorten install time, you can leave out older FW Files.

Example:

If your emuNAND is already 4.5, you
can leave out everything before that.
Same goes if it's already 8.1.0 and
so on...

3. Copy all cia files from your desired FW in one directory on your SD Card
4. Mount and start devmenu2.x.3ds in emuNAND
5. Install devmenu_620.cia (0.19.49 - r53511)
6. Start devmenu_620

- DO NOT INSTALL FW CIA WITH OLD DEVMENU! -

7. Browse to the first file from your FW CIA files
8. Press L+R+A and press OK to start install
9. After installing your FW, turn your 3DS off and reboot

- DON'T FORGET TO UPDATE LAUNCHER.DAT IF THERE IS A NEW ONE -

Don't worry, booting the first time into emuNAND after Update might take a little bit longer.

HF.

Probably only affects emunand.

CamelSnus · Dec 15, 2014

I was hoping to get the "new" 3ds browser working on an old 3ds but it keeps telling me i need to update my console. no plex on the 3ds for now i guess

How? Why? Or is this just a guess again because "GW didn't demo emunand hence they hvaing problems"

these are in the csv files, on the website i refer to in the python code and the op...
did you read the op? come on...

ok that is great news, i thought that the n3ds files wouldn't be a problem to the regular 3ds (just like installing different region titles wouldn't be a problem, because they will just get ignored) - but so NOT installing the n3ds stuff, and the 9.x fw will be ok?

thanks

Next would be xampp local (proxy/wlan) pc update server for new3DS <9.2.0-XXX User

PS: I extracted my 9.4.0-20E Fat16 to validate the FW files usage.

Just a guess since emunand relies on patching arm9.
But it's probably nothing.

Blueie · Dec 15, 2014

I cannot get it to download the FW files. Running UpdateCDN.py gives me the following error message:

File "(path to UpdateCDN.py)", line 61
print '**************************'

^
SyntaxError: Missing parenthesis in call to 'print'

Edit: The syntax I used was:

UpdateCDN.py -USA 9.2.0-20.csv

so my python script has a bug?
maybe, what csv did you use?

how would this be useful? you cannot use the theoretical new version you just updated to because gw does not support it yet... otherwise you could have updated normally... right?

The new version would run until you reboot.

SpongeFreak52 · Dec 15, 2014

I'd be very interested to see if people are able to install US StreetPass games on non-US systems (aka Flower Town on one which normally has StreetPass Garden). It would really be nice if we'd be able to transfer progress over since they take absolutely forever to complete.

Ok so reading through this thread I have to wonder, If someone makes it so devmenu can see system titles you would be able to technically downgrade emuNand firmware from lets say 9.2 to 4.5. And If this is the case then when the new update comes out for gateway (assuming it supports emuNand) then people should be able to downgrade their emunand to 4.5 and then backup via gateway and use a hard mod to restore that backup to the sysNand. I know this is pure speculation but that could finally be the key to downgrading sysNand right?

have you tried this? (do know know what you are talking about or just assuming?) (not trying to be rude sorry!) - because for me i had to reboot to get the 'updated' fw, without the reboot i was still on 4.5, or whatever. maybe not though...

you can technically downgrade the fw but only because you need to trick the 3ds into thinking the lower fw is an update.
even if we could see system titles, that might not be enough, (maybe the 3ds will go crazy if you actually delete an important system title, but if you install a new one over it is ok - i'm not sure)
but to be great, we would want a devmenu that lets's us install titles with a lower version, and that let's us manage system titles.
you talk about downgrading the emunand to 4.5, why not just dump the sysnand again to get a 4.5 dump...?
and when gw supported new consoles at 9.2, why would you want to downgrade to 4.5?
if you have devmenu access you can install cias no matter what, sysnand or emunand.

I haven't tried all of the steps. But I did check settings after upgrading and it was 9.4, then I exited/rebooted and EmuNAND is black.

oh hmm ok then, i only tested twice as i said. did you install the n3ds titles? maybe if you leave them out you will have better luck?

The reason im wondering about this is we don't know what will be possible with the Gateway 9.2 release. There may be features that only work on 4.5 even after 9.2 comes out. Also its quite possible that at some point an exploit will be found that allows unsigned code to run on sysnand but only works on an old firmware version.
