Since the easy installer concept is working,
a dirty flash upgrade feature without loosing data is a very good option as OTA is hard to obtain.
If that is the solution you choose to address this problem, could you please share a guide about how to do it?
Is it really a safe way to upgrade without risks to lose data?
The easy installer is at this link - I will be trying it once I obtain an S9:

Hopefully it will work for me, as the other /e/ install guide(s) I’ve read for the S9 look very convoluted, compared to the Lineage install I just did on my Essential, but that’s a different story.
@Manoj thanks again for the forthright information.
I agree it’s pretty bad to not ship up to date devices… assuming someone has flashed lineageOS and TWRP before, how hard would it be to do so on a fresh new S9 phone, regardless of the devices shipped by /e/? I’m wondering if it wouldn’t be easier for me to just get the device from a corner electronics store instead of going through the trouble of getting an (outdated) one here…
Last time i tried to flash LOS on a Samsung device (a samsung tablet), I couldn’t get root in the bootloader, so I didn’t get very far… how are things nowadays with Samsung phones?
thanks

The official documentation is not relevant, but good source of information :

yeah so I’m familiar with the “stock” flashing instructions. my main problem happens when the procedure deviates from there. i don’t exactly recall what the problem was but I couldn’t sideload TWRP last I tried… i got the OEM unlock, but it would complain about the signature being wrong.
i suspect that recent phones and tablets have protections about that kind of stuff, which is why i’m asking.
Don’t use sideload for installing TWRP, flash it with
$ heimdall flash --RECOVERY twrp-3.3.1-0-starlte.img --no-reboot´
sideload is for installing the system.zip if you choose this method.
yeah well, that works super well when Heimdall works. Not so much when you’re not supported.
Out of the easy installer,
it seems there are two specifics additional steps for the /e/ installation on the galaxy s9 :
after flashing TWRP
reboot to TWRP, do the wipe things,
and before installing the /e/OS_build.zip.
You have to install :
no-verity-opt-encrypt-samsung-1.0.zip
and
VENDOR-27_ARI9.zip
Now you can install the device specific image of /e/OS
build for the ROM of your specific device from :
Thank you for your answer. Yes, I’ve used it to flash a S8 and it worked well.
My concern is that I know how to use it to install /e/ from zero but not how to use it to simply upgrade it without any loss of data.
Just don’t format or wipe /data and /internal storage
Only wipe /Dalvik Cache and /Cache
