For Advance users ONLY, don’t dare to try when you don’t know how twrp and ODIN works at all.
Confirmed working on Korean and International variant.
PS. ENABLE first “OEM UNLOCK” (located in Developers options) BEFORE YOU DO ANYTHING.

HOW-TO ROOT AND/OR DISABLE ENCRYPTION/DM-CRYPT:
We noticed that it could be really difficult to operate when /data partition is encrypted and MTP/ADB is unavailable.
So mwilky of XDA included 2 flashable zips in recovery image itself.
They are all located in /twres/flashables/.
So we must disable encryption/dm-crypt, you just simply flash “no-verity-opt-encrypt.zip”. It will disable dm-crypt and make /data encryption optional. Then you can go to Wipe menu to wipe your /data partition to finally disable encryption.
To root, just simply flash “Magisk-v12.0-arm64.zip”. It will install Magisk on your phone. 🙂
Good luck and God bless! 🙂
By the way this is still on BETA STAGE, try at your own risk.
