PROJECT STATUS NEWS UPDATE: July 17th - Team REBUG has gotten their Switch Modchip Up and Running Perfectly!

The last update we had from Team REBUG on their project status was back on July 4th, that they got in the 'final prototype' PCBoards and now they had time to assemble them, polish up the coding a bit, and installed one in their Nintendo Switch consoles and below we present to you the very first video of it booting up and working, along with the latest Tweets from their project team leader.

Mod chip works

I've tested a few configurations with rcm strapping, hardware auto RCM and software RCM. Easiest by far is software auto RCM and a easy 4 wire install. Oh no case bluge

Seeing Videos are just better, here you go

Nintendo Switch Mod Chip 4 wire install (just showing off without auto rcm) 3 Clicks and its off to OZ

Huge thanx to everyone involved in the Switch Scene!

Check the git and read it's pretty straight forward to me.

It's not clear from the GitHub readme or the linked wiring diagrams thread that you can't flash a payload to the SwitchMe while installed internally and in RCM.

I think a small added note about it would go a long way in helping others going forward.

The documentation other than that point is fine though.

Go check now.

Perfect! Thanks. Agreed that flashing CTCaer 4.1 and chain loading other payloads is the best setup with the SwitchMe and AutoRCM.

hell no,i do rather softmod over modchip,good luck am out.

Thanks for the Answers and the hint with CTCaer.
What makes me wondering is that i succeeded one time to change the Payload with the Modchip soldered in - probably a lucky perfect timing?

Also this would only last as long as CTCaer gets a feature which i want to have as chainloading CTCaer with CTCaer is a little bit strange when config parameters changes........
So I believe there is a real Need to have a way to update the Modchip in System. Probably by Chainloading a Payload which does enable USB Data Lines...

Edit:
Also i need some clearification:
I can "disable" the Modchip by holding its Reset Button.
Afterwards i can boot to Horizon OS by sending a Payload via PC.
So, in Theory i should be able to update the Modchp in System with AutoRCM enabled.
What i am missing?

 

[aut0mat3d]

Gonna reply to myselve:
Gave that another try and it worked:

Held the Reset Button on Boot and injected a Payload via PC to boot into Horizon OS
Double Tapped Reset and inserted USB Cable on PC.
Storage is seen under Windows10, after opening the Folder the Explorer Windows closes, Device not available anymore.
Gave Linux another Shot and under Linux it is working.

As already sated, Updating in System with no additinally Periphery (USB Hub) seems to be a little picky

So, no real need for chainloading

Edit:
This is only an idea as i do not exactly know how RCM really works:
A cute alternative Way of updating would be via RCM Payload and modified Bootloader on the Trinket:
Set the Switch in RCM, double Tap Reset on Modchip
Modchip is only listening on USB Side
Send a Payload with some magic Bytes to have the Firmware Update flagged for the Modchip
Send the new Firmware.
No need for a hacky Implementation of USB mass Storage in parallel to a existing USB Device

hey that looks like my pro mini

actually it kinda sounds just like it too

thats amazing!!!!!!!!!!

Nice rebug boot logo btw! Any chance of a version with a black background?

Sure I'll do it in a bit

Any news about SwitchMe external dongle?

 

[evilsperm]

were waiting on the last revision of the protos.
We have added some features non of the chinese or tx even bothered to think of, and you run a huge risk using their products

 

[kuze]

Sure I'll do it in a bit

Awesome, looking forward to it!

ES my install guy has a question: "There is one particular connection I'm concerned about and that is soldering the 3.3v (red wire) as it highlights two pads to solder to on the switch emmc. Any ideas if that means you can use either one or if you have to solder to both and then make a join??" (The 4 wire install...)

any help is much appreciated.

 

[yacepi15]

Can anyone say if this will work with the switch revision ?

It is like a internal RCM payload injector. So, no.

I have the same doubt. It seems to me that any of them is fine, but a confirmation would be great.
Also, does auto RCM need to be enabled?

If you look closely, it is a solid trace. Therefore both connections are the same. Bridge it if you like.

 

[Moquedami]

Cool. Thanks for your answer!

 

[lordelan]

How do you tell the chip which payload to launch?
Or in general how does it work softwaresided?

A few different ways...

Build your own UF2...
Use quantum_cross source...
Use my source
Use my "chainloader" UF2 file to run any unconverted payload.

That last one sounds the most promising. It just points to a specifig .bin file to which I would have to rename my payload to, correct?
Where can I get it?
