[Samsung Galaxy Note 9 Themes, Apps, and Mods] TWiiTCH:
Allow permission on supersu, or magisk or whatever root method settings. Usually you can do the option once and then you will not have to repeat it, just look for a tick box that says remember or do not ask again or so on. Every time I rooted a phone I used the super user and BusyBox method. As for the note 9 I'm one of the Unlucky ones who cannot gain root due to being on a Snapdragon model and it is the Canadian SM-N960W model. I'm on Android 8 still and will not upgrade because I do not wish to lose bootloader version 1 which would cause me that much more hardship if they do come out with a root and it's only for the version one bootloader. Best of luck to you.

I also meant to ask you, with your route do you have to do something every time you reboot causing years headaches to revert back to normal? I know with iPhones some of their jailbreak methods are called tethered and are a pain in the you-know-what. I'm hoping that's not the case with your phone. I'm just sitting at patiently waiting for somebody to come out with a root method for the note 9. I did try Android pie, but after what seemed like Android slash Google was removing my modded apps without my consent I downgraded back to the last good OS. I'm not going past Android 8.0 until there is a root method for the 9. This app thing has happened multiple times. Can anyone give me any possibilities other than its Google tampering with my apps since a few are not paid. And please excuse me for not paying but 15 minutes of test time just is not enough, once I feel the app will be useful I then purchase, I'm not a total jerk who just takes apps and does not pay for them.

I tried to stay with Oreo but found that applications we're evolving so quickly I was missing out on a lot for the few things that I wanted so I gave in and went back to pie 9.0

If you do a factory reset it will wipe everything on your phone so I would suggest doing a Smart Switch backup using an SD card before you wipe your phone as it will save you hours of time getting your phone back to the way it was. And that's funny, maybe we are long lost brothers or something because I don't pay for apps either. I download modded and cracked apps and if and when I feel I'm going to keep it and it will be of use to me I will definitely pay the money and always have for anything I kept. 15 minutes barely gives you time to get through the setup process of the app and get through the settings menu.

Now The only way I know how you can flash your firmware keeping all your apps was to do what I read & think the article said was all your apps. You have to use Odin and Flash the 8.0 Oreo that you want but you flash it using one of the two CSC file but I cannot recall if it was the one that says home in the name, or the one that doesn't contain the words home in the file name. One will remove all your apps and settings and return your phone to you fresh as a spring Breeze in a cow pasture lol, and the other will leave you delighted and your apps in tact.

I must say you are doing the right thing by researching all this ahead of time. Too many times I've seen people rush through the process then come crying to XDA saying their phone is stuck in a bootloop or it won't boot at all. Just make sure you are happy with the information you have obtained before you go ahead hey.

Also if you have never left Android 8.0 and you free flashback to 8.0 you will need to take out the SIM card and go through the setup skipping all the screens and menus not entering any passwords or information. After that you have to turn on developer mode and turn on ADB and Ryan your commands on the files that cause your phone to update over-the-air or over Wi-Fi. If you forget to remove the SIM card or you connect your Wi-Fi during setup it'll force update on you and you will have to downgrade again. And my note 9 I've noticed has recently gone to Bootloader version 2 so that may be an issue but I'm not sure.
