Hacking Custom Boot Logo for Switch

[ForeverNo9437]

We can already coldboot to cfw? There is an exploit called "fusée gelée"...

I think he means by cold booting booting without anything (like the jig and RCM payload injector)

Hello everyone!

Based on the script one github compiled a simple app on python. It works autonomously.
All you need is a PNG of strict size 308 x 350, other switch does not accept.
Working with actual atmosphere.

Instruction:
Select any PNG size 308 x 350 > Create patches > choose where to save them. The app will create all necessary patches at once with hierarchy atmosphere\exefs_patches\logo. All this stuff you should throw into root folder on your switch and enjoy.
To return the classic logo just remove folder "logo" from atmosphere\exefs_patches.

On Un-patched consoles you can use the RCM vulnerability called Fusèe Gelèe to inject a payload

For patched consoles (any console built since 2018) you need a modchip to inject the payload on boot.

Thanks...

Do we need the original logo as a base?

IPS patches are smaller if you use it.

Sadly the code of this executable do not uses the original logo, so all patches will be 431243 bytes in size not the reduced one what you can get using the old logo ;(

if @Ignorat do not mind I can share the PY code with GBATemp.

By the Way @Ignorat ¿how do you convert the PY file into EXE?

 

[Ignorat]

Hm, mb I'll try to insert original logo in the app. But for me there is no problem with larger patches)

To make .exe file, you need compile it on windows otherwise it won't work. I'm using Parallels Desktop to do it on my mac.

After, you should open cmd in your future app

1) Make a venv

python -m venv venv
venv\Scripts\activate.bat


2) Download everything you needed from your requirements.txt

python -m pip install -r requirements.txt

3) After that you need to copy from venv/lib/python3.13/site-packages the "ips" and "pip" folder to your root folder to where you downloaded the things from point 2

The root folder should look like this

4) install pyinstaller

pip install pyinstaller

5) Compile everything

pyinstaller --onefile --noconsole gen_patches.py

6)...

7) Profit!

[SpeedyFight]

how would you put this into the Switch?

 

[impeeza]

how would you put this into the Switch?

With a lot of care!


you extract the archive on the root of your card. you can remove the PNG file if you like.

or you can extract the archive to a temp folder and copy the atmosphere folder to the root of your sd card. overwrite files.
