Hacking Question Help! Black Screen after booting up switch

[zyklp5673]

When booting up my switch normally, the nintendo logo appears but then afterwards there is just a black screen. I can turn it off by pressing the power button for 15 seconds, then it boots into RCM mode just fine, and I'm able to inject hekate. A similar thing happens when I try to boot into atmosphere, the splashscreen appears, but then it's follows by a black screen. Last night I was able to boot just fine into the normal OS (I hadn't tried booting into atmosphere).

Please help! Thank you

try updating your cfw files

between now and the time of my original post, i restored NAND and re-formatted the microsd, i can ONLY boot into rcm and send payloads. trying to launch the stock sys or atmosphere results in a black screen after the nintendo logo/atmosphere logo.

If you burned too many fuses and went back to a previous backup, then you also won't be able to make it past the Nintendo logo.
There are some posts around here mentioning how to solve that.

If you can boot into sysnand after booting into hekate. Then all you need to do is do a firmware update to fix mismatched fuse count

Your fuse count doesn't match your current firmware. Either update your firmware to match your current firmware or simply enable AutoRCM.
