Load up Hekate and check the fuse count.

Dude you should never do something as risky as this if you're not 100% sure of what you're doing, what basically happened here is that you've burnt fuses when updating your switch (each time you upgrade your version officially, your switch burns a fuse, which is basically a way Nintendo made to prevent from downgrading so you can't downgrade if you have burnt too many fuses) and the switch has detected it and won't let you enter the OS...
Now you should try to restore your NAND backup if you have one, or try to manually update using the pc version of choidujour.

I see in orange marked "burnt fuses 0dm 7/6.

PC VERSION? is it possible to do it directly from the console like i did when i downgrade the version?

Nope, since your console can't turn on, you obviously can't access an homebrew...

Then your firmware is lower than what it suppose to be, fuse got burned.

Wait wtf, you can access CFW but not OFW (when I say CFW, I mean SYSNAND CFW not EmuNAND)??

Sound like your fuse count is 12,

So if the system firmware is 8.1.0 then the system refuse to boot on OFW.

is it a way to fix it? or to upgrade again?

Load up Atmosphere and update firmware back to 9.1.0 via ChoidujourNX, you can get your firmware file at that darthsternie website.

Sorry for off-topic, i'm just curious what was the reason to downgrade specifically to 8.1? ...And especially when you are a beginner at this stuff.
