This works for ALL Galaxy S9/S9 Plus including Snapdragon U.S. models as flashing stock firmware is same for all S9 & S9 Plus.

I do everything as it is written but in the end when I try to launch a Samsung application, it turns out that it can not start because it is a routed phone. I’ve tried a lot of different firmwares and nothing better. Is there a 100% stock firmware?

Which app you are trying to open?


#4

Samsung Health, Samsung Pass isnt work, Bank apps isnt work. I have no idea what to do now :slight_smile:


#5

Samsung Health does not work once rooted and Samsung pay also, you will need to install custom ROM to make samsung health work. For banking apps, they should work with Magisk root.

Hello, I unrooted my SM-G960F with this Italian firmware, because my phone was an unlocked Italian model. I was able to successfully install the firmware but when I go to updates in settings I am met with “Your current software version isn’t supported. Visit a service center.” and when I plug the phone into my windows computer it only shows 15.7gb of internal storage instead of the full 64gb, it also happens when i look at the file app. If you have any ideas as to what I can do that would be great. thank you.

I was able to fix both problems by installing this New Zealand Firmware with the regular CSC file. I was then able to update to Android 9. This then showed my internal storage as 64gb.
