What is TWRP?
Oh come on, you know what it is - don't try to fool me!
In case you're serious, though...

Team Win Recovery Project is a custom recovery for Android devices.
It allows you to back up and restore your data, flash custom ROMs to your device, repair broken file systems, root your device and more.

Read more about TWRP here: https://twrp.me/about/

How to flash and setup it completely?
- First, make sure your phone isn't RMM Locked.
- Download Odin3 v3.13.1, Samsung USB Drivers, latest TWRP's tar for your variant, latest no-verity-opt-encrypt zip and RMM Bypass v3 zip.
- Go to Settings App, Developer Options and enable OEM Unlock (If you don't see Developer Setings, go into About phone>Software info and tap "Build number" 10 times to show Developer Options menu).
- Do a backup of all your important data and files in your phone.
- Shutdown the phone. Once it's off, Power it On in Download Mode (Press and hold Power, Vol + and Vol - buttons together)
- Connect your phone in your PC, open Odin3, go in Option section and untick "Auto-reboot". Once that click the "AP" button and select the TWRP tar you downloaded before, then press the "Start" button.
- Once Odin3 finished to flash the recovery (you should see a "PASS" message), force reboot your phone (Press and hold Power and Vol - buttons together) and once the screen is off, press and hold Power and Vol + buttons together to boot in TWRP.
- Once TWRP is booted you first need to decrypt your /data partition. To do so touch Wipe>Format Data and follow the instructions in screen.
- Once it finished go back at the home screen and touch Reboot>Recovery. TWRP should be able to mount your data partition. Now copy the no-verity-opt-encrypt and RMM Bypass zip you downloaded before and flash them (touch Install and select each zip to flash it)
- You're now able to reboot to your OS without re-encrypting /data partition and without RMM Prenormal lock.

SuperSU is outdated so is highly not recommended. Did you flashed SuperSU uninstaller zip before flashing Magisk?
I was running Magisk on a clean firmware. V16.00 does not install root, and imei flies. V16.6 root is received, but imei also flies.
SuperSu put then just to check for a clean rom and imei also flies.

I've a feeling it may be the kernel since in Oreo kernel Sammy added more RKP security. Gonna release probably a snapshot of my custom kernel without upstream temporarely then bump the version when upstream is done. So please have a bit of patience, give me the time to merge all the MCK N v2.1 tweaks/edits into Oreo source code

It's not a TWRP issue, and it's still unknown if it's a Magisk bug or (high probably) a sort of new anti-root protection by Sammy. I'll check A8 firmware once I get free time

ok thanks, can not it be russian firmware? in your opinion if I try another firmware I could solve?

    Check your build prop you may find your solution.[/QUOTE4]do not understand

    No problem, he was saying to check build.prop to see if there was some strange prop enabled (like Knox Zygote one). Anyway me and @salimskiy find out it's Magisk/SuperSU related and not some kinda of anti-root protection (it's related to systemless root method, in particular the patch of "init" file in ramdisk). I'm gonna report the issue to topjohnwu in afternoon and see if the dev can fix it
