[GUIDE][G800F] Get S Health working with Knox 0x1

I am not responsible for any damage, you follow this guide at your own risk.

Tested on G800F (Exynos).
Things needed:
-root
-Xposed Framework
-Wanam Xposed

1) Install Xposed, enable it, reboot.
2) Install Wanam Xposed, enable it in Xposed modules, reboot.
3) In Wanam go to Security hacks and tick "Disable Secure storage", reboot.
4) In Settings, go to App Manager (or something like that), go to All and search for HealthService, clear data.
5) Do the same for S Health. (you will LOSE ALL DATA)
6) Done :>

Maybe you don't have to clear data of S Health, I cleared for both.

If someone posted guide like this earlier, I will delete my post.

S Health not working

Galaxy S5 Rooted
Model : G-900F
Android version : 5.0
I have tried installing the latest version of the S Health app and when i open it, it says 'S health services needs to be updated to the latest version etc, press OK to update and Cancel to close the app' I clicked OK and it open the Samsung Apps app and it says package not found.
I have tried downloading the apk file from google and when i try to install it says ' App not installed'.
I am rooted and I wasn't the one to root the phone, I bought a used phone. Can someone help me out with how to get the S health app working?
Thanks
