Sx core to atmosphere - black screen

[Kingston]

Hi guys, I have a small problem. I installed a sx core in my nephews switch 2 years ago and wanted to switch to atmosphere today. When installing the latest atmosphere files and using original (sysnand) boot0 and boot1 I get a black screen after the atmosphere Logo. The sysnand is still on 9.1 and the emunand on 10.1 Updated with choid iirc. Any idea what I can do?

I followed this tutorial:

Is the mismatch in the sysnand version and emunand version causing this because I use sysnand boot0/1?


Thank you!
