The official documentation seems not accurate (inherited from previous versions),
since the /e/OS-“T” build generation (like LineageOS 21) are expected to include the updated needed parts of the firmware.
finally the sentence : “your device must be on latest android” (that leads in many case to lose /data by reinstalling full stock software )
now looks not mandatory, at minus on a device already running /e/OS “R” or “S” version.

@Leon
If you reread attentively their post, none of them have performed a Stock OxygenOS 12 installation,
both have performed a “dirty upgrade”
By jumping directly point (8) or (9)
but WITHOUT WIPING ANYTHING
(all the previous steps including (7) have been already done in the past, on a device /e/OS)
Some experiences demonstrate that you can avoid the full stock firmware installation and go direct to /e/OS-T
.
You are all invited to confirm this statement by sharing your personnal experiences in this thread.
Edit : this is correct for some devices, not for all devices…
This method suggests one gets the firmware with the third party app Oxygen Updater, but note that you are not fully reverting the device to stock ROM so at this point you are not deleting any data.
One can check if the /e/OS downloaded ROM appears to contain firmware parts by running payload-dumper-go on the downloaded ROM. One could follow this Walkthrough, but run payload-dumper-go with no -p option so that all partitions are extracted.
That is it! But I think I would run Oxygen Updater, so that you get that upgrade (if it exists) in case you should need it. You could collect the upgrade onto an SD card or usb stick.
Edit, and of course have a backup of things you regard as essential, in case something forces you to format data.
From my point of view
There is nothing bad in running Oxygen Updater, and upgrade the rzcovery-e, But
in addition with needed firmware parts,
Are also included into the main /e/OS install .ZIP file.
And recovery will be updated if you tick the “update recovery” case during first boot wizzard.
So, in my opinion, to reach “an user very friendly process”,
you can avoid the stock updater, and manual recovery upgrade steps, you could directly download the 2.2-t-dev.zip, and then,
Do I understand it correctly, that all I need to do for an dirty upgrade is e/OS image and nothing else?
And if yes, would this also work for my Samsung A52 to get from official S to community T?
If not working, or if you decide to upgrade Samsung Firmware, take the A525FXXS6DWK2 firmware as it is latest android 13(T) based
you may preserve your /data if you don’t flash CSC
you also can wait a month for the release of /e/OS-U version
