Homebrew Question Choidujour RCM?

Dave_Chad · Dec 5, 2019

I'm wondering if it is technically possible to create an app (or payload rather) that would update firmware partitions on emunand and sysnand without actually booting into them.

The reason i see this as useful is i use emunand and update with choidujournx no problems. However to update my sysnand which i use online i have to update officially then re-enable autorcm each time.

Would love to hear why or why not this could or couldn't be done.

Ok maybe i didn't word is simple enough... An RCM firmware installer that writes firmware from sd in a similar way to choidujournx but from RCM. So not needing a pc (other than to obtain firmware) and not having to run through the manual steps that can potentially brick your switch if you have fat fingers.

Well ChoiDujour should be updated for later fw updates?

I think he means "is it possible to create a ChoiDujour payload?"
I have a feeling that this guy accidently updated his Switch and can't boot into CFW anymore.

If it was possible to run ChoiDujour as a payload then it might also be possible to downgrade without access to CFW or a NAND dump.

I have no ideá if it's possible or not though.
