Since you could watch it, i assume you already opened it right.Of course its normal to think that far far latest update would be better. So thats my reason.
Problem is, it would immediately boot to OFW. Rather than glitch glitch sucees then START. When you press on, the switch turns on and shows nintendo logo(OFW) while simultaneously glitching(of course glitch is already late)
You might check the RST line.
I remember in the Q&A:
Q: GREEN, but instant reset
A: Clean flux near the RST point
