How do you make items to convert to 1.10?

You cant "update" the stats but what u can do is like if you want 1.10 trangoul's. go to attributes and change it to unid. Then save it to save folder. Then update and go into shadow masters and upload the unid trangouls to your character and get into the game and walla you have 1.10 trangouls. (Worked for me)
