None of these answers are good for somebody that doesn't know the first thing about hacking a 3DS on firmware 11.0.0.
I know, because I spent 3 days reading all the messages on this board (and on reddit) trying to figure it out myself. The amount of misinformation/internal language/guides for people that already know what is being discussed and the "useful keywords" in the subject being distributed is astonishing.
Here are the most important points (I could write a longer message, but I really don't feel like it and, if I figured out, he can as well). You already know the first three or so, but i'll write them down anyway.
1) You cannot, at this point in time, install any kind of custom firmware on a 3DS (new or otherwise) on firmware 11.0.0 or newer by yourself, with a single 3DS. Period. You can, however, run *some* homebrew software by using a couple of methods that allow the "homebrew launcher" to be run, which will then run homebrew software out of your SD Card.
2) In the not-so-distant-future (end of December), we all believe that a single piece of homebrew software will be released. That homebrew software will allow you to run YET ANOTHER piece of homebrew software (that currently doesn't work on 11.0.0 or newer) that, with the help of a DSiWare game purchased officially from the nintendo eshop, will allow you to *partially* downgrade your firmware from 11.0.0 to 10.x.x (I forget).
from this point you
will be able to proceed with a complete firmware downgrade (to 9.6.x, I think) and install custom firmware.
3) "What DSiWare game", you say? Once upon a time, there were between 4 and 6 DSiWare games (depends on your region and which point in time) that you could buy on the 3DS eShop that would allow one to downgrade their firmware. Nintendo removed all of those games from the store (making it impossible for you to purchase them on a new Nintendo ID) except for one, "Legends of Exidia". If you ever bought any of them, you can redownload them. If you still have them installed on your 3DS, you can eventually use them to downgrade your 3DS. If you performed the custom firmware install on a previous 3DS (which means you had the DSiWare titles installed on it at one time), you can transfer that 3DS to your New, recently purchased, 11.0.0 3DS and perform the downgrade/CFW install. Currently, on 11.0.0 and forward, by yourself, you
cannot use the DSiWare exploit. However, you will need a compatible DSiWare title.
4)
IF you want the ability to downgrade your 3DS firmware by the end of December, you
MUST have one of the DSiWare games
AND be on Firmware 11.0.0 or 11.1.0. If
you just want to be safe and be able to downgrade your firmware in the future IF and WHEN a new exploit comes for firmwares on 11.2.0 and forward, you just need to buy this DSiWare game before it gets removed from the store.
In your particular case (being on firmware 11.0.0), the ideal scenario is this:
- You need to use one of the available exploits (be it "browserhax", "cubichax" or any other that still work. They are called "primary entry points") on firmware 11.0.0 to run the "Homebrew launcher"
- You need to run the homebrew application "cttr-pwn", which will allow you to log into the 3DS eShop with your current, non-updated firmware and buy "Legends of Exidia" before it gets removed from the store
- People will suggest that you also download "Steel Diver" from the 3DS eshop - A free game that allows you to run the "Homebrew Launcher" after you already have access to the homebrew launcher (called a "Secondary Entry Point"). This will be used, from now on, to run the homebrew launcherinstead of the "primary" entry point.
- You then need to
wait until slowhax is released. And by wait we mean "do not update your firmware from 11.0.0".
I've owned a 3DS for a while, but never really cared about homebrew in it. Recently, I saw a reddit post that made me do this entire research through the course of this week.
This thread tries to provide a guide that will allow a N3DS on firmware 11.0.0 to run the "Homebrew Launcher" by using a "Primary Entrypoint" that doesn't require any extra hardware (a physical game, for instance) by using the "browserhax" method (which uses the web browser of the 3DS itself to run the "Homebrew Launcher"). Basically, it will teach you to do the "first step" on my small, numbered description and provide some guidance on doing the other steps. It's aimed at people that bought N3DSXLs during the black friday sale.
You have to understand that the "browserhax" Primary Entry Point was found to not work on firmware 11.0.0 anymore. However, this reddit post provides some information on how to make it work again on N3DS running 11.0.0. Some people will tell you that it doesn't work (without doing any research) and others will tell you that they couldn't get it to work. That thread itself and my personal reserach on the subject (which you can read on that reddit thread) show that, unless everybody in there is lying, the method works on N3DS that are on firmware version 11.0.0, but don't work on OLD 3DSes that are on firmware version 11.0.0.
However, this is all "preparation" for when/if slowhax comes out. Actually applying a custom firmware to your 3DS is not a thing that's explained in any message in this thread or in the reddit thread I posted. The official
3DS Custom Firmware Guide will explain how to actually downgrade your firmware and install custom firmware, but it's currently not updated to provide "slowhax" information (as it's not out yet).
I hope this post was somewhat enlightening. I'm not a concise writer and writing this properly for everybody is not a thing I want to do - but somebody should.
