Sorry if it sounds stupid but the jack thing makes me think about ground issues. What if we flash it again but with ear buds plugged during adfu?
I have no time to test this these evening, if someone wants to test it?

To go with this, can anyone try changing the cable?

Just gonna repeat what I posted on the reddit...

From what I noticed in the video, it didn't fix the issue but it did seem to reduce it to the same level that I experience with my machine.

So I guess it all depends which of the 3 joystick boards you have. You will either have no issue to begin with, a minor issue (which in my experience isn't improved by this), or a larger issue which is brought down to the same level as the minor issue by plugging in headphones.

What a bloody weird console lol.
 
Something very strange here. I made many tests and flashes this evening. On one of them the bug disappeared. I thought it was because of my changes in the finition I posted here but another flash and the bug comes back again. That and the sound's correlation and jack audio seems to confirm a power issue (or damage during flash process). I'm using a micro USB otg and a cheap micro USB cable. I'll look for a better USB C cable. Who was using an otg here? And was it a success or joystick bug?
 
Also i'd just like to say that all the progress we made, the only real dev to help with this cause was MadMonkey... This should also show those guys who keep asking for hacks, that if you just read a book or google sometimes, you can make your own hacks and progress
 
My NGM is a Japanese version,and neither the headphone nor the volume off did not work for the bug.

I tried to replace the resister. It shows that only one resistor needs to be replaced. For the left direction, 15k or 20k may work. For the right direction, 7k may work. I am still testing.

This is the resister controlling the left direction. It is a Japanese version. Two days later, I will replace it with 15k or 20k.

I tried yesterday using as cheap and as low powered as possible, and many different cables, USBC to USBC, USBC to USBA, USBMicro with a USBC Adapter, and then I tried using 3, 5, 10, and 15w power supplies, I flashed using Windows XP, Vista, 7, 7 VM, Ubuntu with Qemu... I cannot replicate getting the bug...
