Hi guys
Can anyone help me and write how to invert these commands?

mv /usr/share/themes /home/opt/themes2
ln -s /home/opt/themes2 /usr/share/themes

I did it to make more space in roots and now after every reboot my phone is in basic theme.
I tried to do
mv /home/opt/themes2 /usr/share/themes
ln -s /usr/share/themes /home/opt/themes2

but of course it doesnt work. I know I shouldn't do that but I did and now I need some help.

Thanks in advance
