About a month ago, user @Reisyukaku, the creator of ReiNand on the 3DS, teased that they were in the process of making their new custom firmware. What we initially saw was just a custom splash screen. Now, they've publicly released the highly awaited ReiNX CFW for the Nintendo Switch.

Rei states that this is a simple, modular CFW, and that everything works together independently. They'll also be working on a custom sysmodule for ReiNX, as well. You can check it out and compile it yourself at the GitHub link below.

The modular switch custom firmware

Usage:

Put ReiNX folder on the root of your switch's SD card and run ReiNX.bin with your favorite fusee launcher.

Compiling:

You'll need devkitpro with devkitA64 and run make

Features:

• Loads all KIPs from /ReiNX/sysmodules/ directory
  
  
• Optional custom kernel/secmon/warmboot
  
  
• Default kips with exefs redir from /ReiNX/title/{tid}

Don't forget, you can keep up to date with all discussions about Switch CFW in that specific subforum here.

How dare anyone flame this CFW when they don't even know what it can do...oh wait.

I'm not going to comment anymore though.I would like to see it succeed

Its really funny to see all those flamers here XD. Yeah im using sxos.... why? Because they were the first with all those features like signpatching ect. Which fits best to my needs. But why are some people saying that ReiNX is shitty? Because you cant do piracy and all the other stuff?
Cmon folks. That new FW is out for a few hours.And its really nice to see that there are other groups/guys/girls whatever working on their own CFW. Lets see what time will bring. Perhaps SX OS is the first CFW with the most wanted features.... but that doesnt mean that time will not bring something else that is way much better. There is no best CFW.... there is only the best CFW which fits best to your needs.

 

[Searinox]

Always go open source!

 

[tomGER]

Also,good job with SDFilesSwitch.its on my essentials app list

Aww thank you <3

Congrats to the scene for finally releasing a CFW that has sigpatches and can load backups. Oh Wait it doesnt....... Oh well no reason for me to dump my SX pro yet then. TBH the scene is gonna have to have some killer features to make most people forget about TX and SX OS. All the while TX are selling more and more dongles to people who dont know about the "Scene" and just want an easy route to piracy

On a side note.... I went to a car boot sale/market this morning and there was a guy there with a box of SX Pro (at a glance looked to be around 20 units), he was selling them for £50 and sold 4 in the 15-20 mins a stood near his stool. Had a quick chat with him and he wouldn't reveal how he managed to source so many units.... He let me have a look at one and compared to my own unit it looked genuine. He was showing people how it worked on a Switch console he had there.

I’m still waiting for Atmosphere CFW. I’m sure it would be a lot better.

But really, we need sig patches, and we need to be able to install this so it runs on boot without having to use a PC every time.

good luck with the 2nd part

Hopefully you can enjoy your switch in this generation of gaming

I remember in the early days of 3DS hacking there were a number of CFWs to choose from. I ended up going with Cakes because the idea of a modular CFW sounded good.

In the end nobody ever made any modules for it.

In the very early days of 3DS CFW, it wasn't until a fork was released with signature patches that everybody flocked to it.

 

[sarkwalvein]

So it wasn't a troll...
Well, perhaps making it so ambiguous as to pass it as a troll was the troll itself.
I guess I've been trolled!

Congrats!

I hope it will be possible to change the boot pic, fuck these weebs, man

But,
# this code is political -- it stands with those who fight for weeb rights
# don't like it? suck it up, or develop your own damned CFW ^-^
/s

Oh wait... too soon?
Oh wait... too insensitive?

Let's face it, "political code" is nonsense!

So this is more of a bootloader than a full featured cfw.

I'm mot blaming anyone, but teasing it fully as a cfw isn't really good... (in some case, competition isn't really good, and I believe that, in this case, it isn't.

It's still a Wip dude not a release, chill out and be patient , same goes for every "Pirate" out there.cause i can't see why wouldn't anyone be angry about this if it wasn't for the sig patches and the backups , also, he clearly stated multiple times that he's still working on sig patches and they've been a pain in the ass for him..

I just closed Pornhub for this. no regrets.

Well all those who claimed to be testers were touting xci and and nsp (?) compatibility, so I understand the frustration, even if I don't own a switch and didn't buy into the hype myself. I can just see where the naysayers are coming from.

 

[Gold_Experience]

Sick stuff.
Looks like SX OS will slowly get ditched now.

Lol i just bought that for piracy alone.

Where does it say what system firmware is works on? I assume this is only up to 4.x.x, huh?

Where does it say what system firmware is works on? I assume this is only up to 4.x.x, huh?

Looking at the source code in github, specifically at firmware.c, you can see it has offsets defined for the following firmware versions:

static const pk11_offs _pk11_offs[] = {
    { "20161121183008", 0, 0x1900, 0x3FE0, { 2, 1, 0 }, 0x4002B020, 0x8000D000, 1 }, //1.0.0
    { "20170210155124", 0, 0x1900, 0x3FE0, { 0, 1, 2 }, 0x4002D000, 0x8000D000, 1 }, //2.0.0 - 2.3.0
    { "20170519101410", 1, 0x1A00, 0x3FE0, { 0, 1, 2 }, 0x4002D000, 0x8000D000, 1 }, //3.0.0
    { "20170710161758", 2, 0x1A00, 0x3FE0, { 0, 1, 2 }, 0x4002D000, 0x8000D000, 1 }, //3.0.1 - 3.0.2
    { "20170921172629", 3, 0x1800, 0x3FE0, { 1, 2, 0 }, 0x4002B000, 0x4003B000, 0 }, //4.0.0 - 4.1.0
    { "20180220163747", 4, 0x1900, 0x3FE0, { 1, 2, 0 }, 0x4002B000, 0x4003B000, 0 }, //5.0.0 - 5.0.2
    { NULL, 0, 0, 0, 0 } // End.
};

So, though that doesn't mean it support all of those firmwares, it means that at least effort was done to make it work on those versions (and quite probably it works on those versions).

So I would say it works from 1.0.0 up to 5.0.2.

Well, no 5.1.0 support killed my interest entirely, sorry, to be honest.

Yeah same for PS3. The answer is: Luma3ds and Rebug cfw are the most popular/widely known, with the most features (still in development to this day) and are therefore the best.

Hopefully you can enjoy your switch in this generation of gaming

I’m just so goddamn broke rn, I can’t afford a switch unless it involves stealing from my parents wallets (kinda bait w/o laundering it tbh, and yh got caught with their money when I wanted to buy cigarettes). Cuz I’m still a student I have no time 4 a job... I have like 6 consoles, two phones & 2 PCs but they’re way too precious to sell
