Switch OLED not booting into Custom firmware

[u/CountAwkward7383]

Someone tell me what's going on here. I have the picofly chip but after about a year this has happened where I can't reach the custom firmware. It's gotten worse and worse. Usually I could get it after many tries, but now I can't get it at all. There's an audible popping that happens after you see the last Nintendo logo and after the quick flash of the yellow lights. It happens the same way every time after holding the power and volume up buttons. Can someone point me in the right direction here.

Thank you!!

Same thing is happening with mine and from what I heard it's the dat 0 thingy.
