Hi there, this is my very first post here. Thank you for your time and I appreciate your help.
I've been using sx pro for a long time and it worked really well.
However, after I updated my console to 10.0.2, I couldn't run the CFW anymore. I updated offline since I got banned from Nintendo months ago and I really wanted to play ACNH.
I also updated my sxos to 3.0.3 beta which I think is the newest version.
It shows a black screen after the SX logo screen. Also, it says I need to update my system if I want to use my memory card. I don't know if it is the reason I can't run the CFW.
What should I do to run my sxos again?
