Samsung said would stop supporting "my knox", in favour of secure folder. My knox is just an app to hide your data, not the fuse that trips when you root your phone.
All l can say to this is l have used it before and never tried knox in anyway or form
Again, 2 different things. You used it before and you tripped your hardware knox. Do you know how to go to the download mode? Turn your phone off and push volume down, Bixby button, and power button all at the same time until a green screen appear. Push the Vol Up and you are in download mode. Several lines from the top is your Warranty Knox Status. It is usually 0x0. If you install TWRP, it will change to 0X1. That is called you tripped you knox. Feel free to do whatever you would like to do. Regardless, this is off topic for this group.
If your sick of waiting for Samsung to release the update head over to SamMobile they now have the official Oreo update for the SM-G955F which most of will have firmwear version G955fxxu1crap
This gets more and more bizarre. The Oreo rollout has been halted according to Sammobile!
Let's hope it's for 8.1 as the notification for system in 8.0 is horrible no idea why Samsung chose to leave it when you remove a notification from the notification panel it also clears the dots should have been made to leave the dots on the apps, the way it is in 8.0 cheap release is a step backwards in terms of notifications.
Not confirmed yet, but it looks like the reports earlier this week that the Netherlands will be receiving the update next week actually referred to this new version of the firmware.
