I have a strange issue. I installed a mod chip to my oled and everything worked fine for 2 days.
but now when I put my joycon in, the switch goes straight into a bootloop with showing the Nintendo logo over and over again. Without joycon attached or wireless use everything seems to work and I can use everything as expected.
I disconnected the chip, changed the controller and the joycon rail but still the same issue.
Oh and except the 3,3v pin everything seems to have only the half value with my multimeter
