Hi,
I confirm you can install directly on a S9 (Exynos) with a firmware from Nov 2019 (important) and Pie. DO NOT DOWNGRADE Pie. Install directly.
Steps adapted from :
Link: [HOWTO] Install /e/ on a Samsung smartphone with Windows easily
-
install Odin on Windows (Heimdall/adb or Jodin didn’t worked for me on Linux)
-
install Samsung Drivers on Windows (end of linked page above)
-
put no-verity-opt-encrypt-samsung-1.0.zip, VENDOR-27_ARI9.zip, e-0.8-o-2020041249358-dev-starlte.zip on SDCard (the links for the 2 first files are higher in the current topic)
-
install TWRP with Odin. Uncheck Auto-reboot and use the MANUAL method
-
in recovery mode, advanced wipe Dalvik/ART Cache, Data, Internal Storage, cache, system
-
repair/change data partition (format exFAT, format back ext4, resize FS) to crypt data afterwards (higher in the current topic)
-

Wait 5 mins.
/e/ starts -
crypt the phone (parameters, security)
-
if you want, root the phone with magisk AFTER crypting (optional)
