Help with upgrading firmware on rooted oppo R9S plus

I had rooted my R9S plus - CPH1611 using .
had no issue at all till now where I receive an OTA update.
the phone is rooted and recovery is on twrp.
the phone downloaded the update (a patch) automatically, and when I try to install, it is not successful.
I tried installing in twrp where I got error 7 which says "This package is for CPH1611, this is a R9s Plus device.".

I looked into build.prop, and it is stated as CPH1611 already.
Please help and advise what should I do or what can be done?
