Thank you all, my s-pen now is working greate and I'm happy again with my note 8.
Yes, it stills have the charging off issue, but I prefer an working s-pen.
-- Steps I took --
I did use sammobile 4.1.2 fw.
instaled usb drivers trough kies (had to reset tablet some times and put in odin mode some times too to get them working).
tablet in odin mode (power+home+vol down)
ran Odin, put rom into ap line, and started.
Waited till odin got success and blue bar.
Tablet got reset loop, them I put into recovery mode (power+home+vol up), wiped and erased data.
After that all working greate.
ah.. now I got 1 warranty void on knox.. so sad.. lost my lost warranty, samsung will never help me again... ops.. wait.. they didn't help me with s-pen issue before. LOL.
Many many tahnks everyone.
