I bought a pre-modded OLED Switch that only booted into RCM around 1/20 of the time. The LED on the Instinct V6 chip always showed the following LED sequence:
Purple flashing > Quick orange blinking > Purple flashing for a long time > Red blinking > Boot into OFW
This error is not in the list...
You can see pretty clearly in the video that it's a yellow or orange hue, definitely not white.
Even if it were white, the combination still doesn't correspond to any of the error codes on the Instinct V6 table.
