I want to downgrade my Asus device which is currently on Oreo to Nougat.

I tried to use the "UL-ASUS_X00LD-WW-14.0400.1707.149-user.zip" from the official site, thinking I can do it by applying update from SD Card but that's not the case. It gave me error; Error in sideload/package.zip (status 4)

Any help regarding the same will be appreciated.
