Notes / Warning!
  1. Use at your own risk, I’m not responsible for bricking your device.
  2. Using the incorrect file may brick your device.
  3. If your target device has a custom firmware flash counter, Rooting will trigger it. If you’re lucky, Triangle Away has support for your device and can be used to reset the counter.
  4. If you have a KNOX-enabled device, Rooting will trip the KNOX WARRANTY VOID status !
  5. If your device storage is encrypted, Rooting will wipe your data !
  6. If you have locked bootloaders, flashing one of these will probably brick your device – with the exception of Nexus devices, which will usually automatically “OEM unlock” and wipe your data !
  7. Make sure to backup your important data before root it.

Okay, so I completed the whole process, here are my observations:

The method provided above almost works. The problem is, that everytime you reboot to system when you are not rooted, TWRP will encrypt your files. So the solution is, that you have to format data and then install dm_verity and Magisk after each other, without a reboot! After that, you can boot to your system and set up your phone.

I did what you said but still encrypts after reboot. Latest Magisk.

Could someone tell me if it is compatible with the November update CTK1?

I have managed to root the phone, you can install everything and configure it, but after turning off the phone, I can't start it does bootloop, and it returns to the prompt "The phone is not running Smasung official software ..." never finishes starting? What do you recommend me to do?

I reloaded the original rom and did the procedure again, taking into account the clarification of installing install dm_verity and Magisk after each other, without a reboot, and everything went well!

Hello abraxasboot !
So,for you ,the only problem was that U had to flash the files one after the other without rebooting ?
No other problem since that ?
Is the phone reacting well ?
Where did U find the official rom ?
Thanks and have a good day !
