you dont need vendor if you flashed 12.1 , just wipe data , system , vendor , cache. format data if coming from 2.5 stock or encrypted ROM . Flash rom zip. done
so if i reflash stock rom (build date march 2022) i should be able to flash this rom no problem right?

smooth rom, I have been using it for a while now, thank you very much.
I have a problem, I can't set the default APNs since version 12.1:
I can't delete or change them.
when I select an APN, if I tap on the three dots, I get only :
Cancel
However, if I create a new APN, I can modify or delete it as usual.
Is there any solution to this?
I found a bug, everytime i turn wifi hotspot on i must turn on extend compability if I don't turn it on the hotspot won't turn on
Known bug. No fix yet.
Seems like Dolby Atmos doesn't work.
There are few broken profiles like (Game1,Game2 and Special Audio) other profiles workx

Sorry don't know
* How it works It is a very basic script that will patch the fstab to enable encryption
* How to use :
Wipe clean.
Format data to ext4.
Flash ROM.
Flash EFE
Reboot.
REMINDER: ALWAYS FLASH EFE AGAIN AFTER ROM UPDATE AND BEFORE BOOT
Warning 1: Best used with ROM that come gapps version of arrow. Some gapps (like flamegapps) can't survive the encryption and will cause a bootloop after update
Warning 2: Any ROM update will overwrite the EFE changes and the ROM wont boot.
You need to flash the zip again to boot. While it will boot fine and nothing wrong will happen I will advise to not forget to flash it (so update manually/and flash the zip)
Thanks to thenist for his help and support to make this work properly

Is there any solution about this one?
The only thing to keep me away from this beautiful rom is that the OS is not recognizing the second camera. I tried with GCAM, OpenCamera but none of them does really zoom using the second camera.
Is there any solution about this one?
What do you mean second camera ? My zoom works perfectly fine with different apps .

It does not use the physical camera though. Samsung has two cameras whether one is used when you zoom 10x.
Only the main one is used. Try to cover the second camera with something and you will see that camera being ignored completely

TWRP works fine.
Thank you
But what about the issues with encryption, were they fixed?

1. Look for basebands/modems (section: S9 Guides, News & Discussion)
Read carefully, pick the latest for your device as a TRWP flashable .zip
s9 is SM-G960, s9+ is SM-G965
(wipe everything, format data)
2. flash ROM
3. flash gapps (if not included)
4. flash magisk (optional)
5. flash the trwp flashable modem
6. reboot
Hey I can confirm you can fix the VoLTE and VoWIFI by yourself (when clean install)

Ehmm, sorry to say, but updating your modem has nothing to do with voLTE/voWIFI (you can do that without clean flash btw). A too old modem can cause problems, yes, but voLTE and voWIFI are proprietary and closed source.
So AOSP Roms are simply missing the needed firmware. If you need it, you have to use a Stock-based Rom or be a godlike reverse engineer, resulting in Samsung going to trial.
In short: voLTE/voWIFI is not fixable, unless Samsung wants it fixed.
