You can have safestrap on pie android 9 which gives you some ability to modify system files flash zips etc and have access too data and other partitions that are normally blocked but you can not run root on android 9 because root on android 9 requires a modified boot image.
Phone that fail DRK or DM-Verity check in recovery and wont boot this will work on those.
All Samsung stock rom features will work just like a fully stock rom will

Anything here with a .7z extension will get unzipped before using
Anything here with a .zip extension will get flashed as zip in safestrap
Anything here with a .tar or .md5 gets flashed in odin
Anything here with a .img extension gets flashed as image in safestrap

Prerequisites Before Flashing Pie With Safestrap Roms

You must have safestrap installed. Method too achieve this found Here


Pie With Safestrap Roms

1. Copy pie system image to your phone while phone is booted normally the image is too big too copy while booted in safestrap. This image will be flashed in safestrap using install tab and the the flash image tab at bottom. System images get flashed too system partition

2. After done flashing pie rom on initial flash of pie system image in safestrap you need to wipe data in safestrap reboot too download and flash BL_G95******_LEAVE_SAFESTRAP_V8.tar.md5 in BL slot in odin and G950U_CACHE_FORCE_REBOOT_V8.tar.md5 in Userdata slot in odin the phone will boot too stock recovery where you need to wipe cache and reboot .

3. Rebooting too stock recovery only needs to be done on initial pie system image flash or a reflash of a system image in safetrap. Rebooting back too safe strap and leaving will only require flashing BL_G95******_LEAVE_SAFESTRAP_V8.tar.md5 in odin BL slot and you can just let phone boot normally.

4. To enter safestrap on pie rom you will need too reboot too download mode and flashBL_ENG_BOOTLOADERS_SAFESTRAP_G95**_V8.tar.md5 in odin BL slot and when phone reboots it will reboot directly too safestrap. This may take a few seconds too up to a minute so be patient.

5. To leave safestrap and return too rom reboot too download mode and flash BL_G95******_LEAVE_SAFESTRAP_V8.tar.md5 in BL slot of odin and just let phone boot normally

6. Sometimes in safestrap when flashing zips you may get an error about failing too unmount system/resources busy most of the time this doesnt affect anything but if you get the error it would be a good idea to reboot recovery before flashing or doing anything else required in recovery.

How about host adblocking?
How about access to data partition?
How about ability to delete or add apps to system apps?
How about make real data backups?
How about add particular CSC features or easily change CSC code?
How about add a CSC code not available on stock phone?
How about bypass certain hotspot restrictions?
How about edit the build.prop to maybe add multiuser support
These are just a few things you can do with safetrap?

Wow! Thanks jrkruse!!! I haven't use my S8+ in a while. I'm glad you are still supporting this ancient phone. I will have to try this out and see. Keep up the great work!!!
