Ripee is doing builds.
To fix your device,
goto the other thread, and download twrp, rom, and arm gapps, not arm64.
Boot to download mode, in odin deselect reboot device, flash twrp , force reboot with download mode (home power vol down ) buttons, and as soon as device screen goes blank, click recovery buttons ( home power vol up ) immediatly to access twrp.
Flash @ripee build, not this one, and gapps 8.1 arm, not arm64
Method 2, download stock rom, and flash with odin
