Sorry, I was apparently unable to reply to you until several hours later due to restrictions on new forum users…
Dark mode.
As far as I can tell, nothing is missing, it was just that the icons and font were extremely small and had to be adjusted manually in the display settings, to the big difference from the previous “Oreo” version.
I don’t understand where you are going with this?
Still I must add that I have taken another firmware for the ‘vendor.img’ as mentioned above and namely the DTM version (SM-G965F_2_202102065705_y7bp6konpr_fac) because according to IMEI that was probably the previous standard and also the firmware was somewhat newer.
On the one hand, I am of course happy that it has now worked at all to install the Q version of /e/ on it after all. Would I like to have a “clean” installation? Of course that would be the absolute non-plus-ultra.
Addition
I have successfully flashed a new firmware to the “stock” Android 10 using Odin. I found the correct firmware here. https://www.galaxyfirmware.com/model/SM-G965F/DBT/G965FXXUFFUE1
and then I could install newest TWRP and /e/ dev Q version successfully with your HOWTO Guide!
The (7) adb sideload wasn’t working for me, so I did it with, the (8) SDcard method.
@manoj, could w/e/you host an Android 10 vendor image for the s9 /s9+ device in ecloud.global ?
and recommand thoses steps as a workaround for those who have already OTA updated runned the easy installer on s9/s9+ are desapointed with their Oreo, and are afraid about flashing
if
updated to Samsung-Android-10 on the s9 / s9+ → did the easy installer process [ emulate heimdall + unlock the bootloader + flash twrp to /recovery + format /data + reboot to recovery ? + wipe /system + install dm-verity + vendor 2018 + emulate adb + sideload e-0.17-o-stable from the computer (to /boot and to /system) + wipe /cache and /dalvicARTcache ] = /e/Oreo on the device
Then is
→ boot TWRP → format /data + reboot to recovery + wipe /system → install android 10 based vendor.img → install /e/Q.zip from SDcard (to /system and to /boot) = regular /e/Q on the device ?
It would help if the ‘Easy Installer’ would name the version it will install - then if you want a newer version that the installer does not support, you can install it manually. This would have saved me a lot of trial and error, and probably others as well.
