Standard installation
1. Install TWRP before installation and do a full wipe + delete the "Android" "Android.Secure" and "Lost.Dir" folders on the external SD card. MANDATORY!
So that really all the remains of the previous Rome are gone and everything runs without problems.
2. Download file 01, unzip it and flash it with Odin in AP. (Is OJ3 bootloader and modem in one file.) Then when the phone restarts, go straight to recovery (TWRP)
3. Flash file 02 in TWRP (Rome) then directly without restart 03 (Hvitamin Kernel + Fix).
4. Restart and set up the mobile phone including the essential fix (make sure it comes somewhere between the Google account setup and the Samsung account setup.)

Bug fix
Here updates / bug fixes that should be made after setting up (gallery and SCloud)
In the Updates / Bugfixes folder you will find 2 files (APK) Once an update for the Samsung Cloud so that you can restore your data from the Samsung account and sync later. And the other is an update for the gallery so that display errors disappear if you have them.
The standard Samsung keyboard has a problem with the dictionary
Look that you have also set German for handwriting recognition and download it again. After that, the spell check also works while typing.
With the themes there is the problem that after a restart of the mobile phone the theme is lost or parts of it. And you have to apply the theme manually again. (using the xceed kernel)
1. Select the standard theme and remove all themes icons and background images in the theme store.
2. Removes all "Themes" folders in / Data / App / with a root browser
3. Removed the "Overlays" folder in / Data /
4. Create a new "Overlays" folder in the same place and give it all permissions (777)
5. Go to Settings and Applications and All Apps. There you look for the theme store and delete the cache and all data.
6. Restart the phone.
7. After installing new themes you will now keep them after a restart.

Important: This solution is only available to users after you have installed one or two themes, applied them and restarted them. Since it can happen that otherwise the Theme Store refuses its service with a constant "FC"

You can find all files here.
