Hi Guys
I want to update my c9 pro with Odin (home_csc) from nougat to oreo.

i know i can backup my data and flash it with normal csc but i dont want to wipe my data.(app data).

what can i do ?

You can update it with home_csc without loosing your files if you are still on stock rooted rom. If you are in custom rom you will loose everything. You can go ahead and update it with odin without any fears.
