Back to my Problem. I am not sure if i did it right that i got to 9.2-20U.
I got a Blackscreen saying i need to reboot my N3ds...( click the power button bla bla... if thats not working i should write to support).
And this is what downgrade_check is telling me and I am not sure if i did it right or wrong.
Thank you anyways for your effort you did a big progress in my desperation
