/e/OS on Samsung A52s (doc.e.foundation)

Hi there, would like to try eOS on my device, but I think the documentation is out of time. I did flash Lineage a couple of times before, but already struggling with the pre-install requirements as the referred vbmeta.img is not in any of the downloadable .zip

Download the /e/OS build zip file from the section marked ‘Downloads for a52sxq’. Extract the contents of the /e/OS build zip file. You will find a vbmeta.img in the extracted files.

Also I am wondering if it really needs to be a special Odin version as mentioned in the doc. I am running Linux and found Odin v4 1.2.1 ad wondering if it would work plus how it works as this is a CLI Tool.

Anyone with experience around?

Okay, I made it. So here is my solution under arch linux.

activating OEM unlock via dev. options
- if its not available it helped me to disable "auto updates" in dev options and return the date to anything in the past, then restart the device. If the OEM Unlock button is still not available, try other solutions
Downloading and installing odin4 via paru
go to linage repo and download vbmeta.img manually (https://download.lineageos.org/devices/a52sxq/builds)
Open a Command Prompt in the folder where the file was downloaded and TAR the file by running tar --format=ustar -cvf vbmeta.tar vbmeta.img
go to download mode via Vol. Down + Vol Up
it will now ask you for unlocking the bootloader by following on screen information
in the turqois screen it should say now bootloader state = checking+
- if not do a system update (this helped in my case. other say you must run the device with sim and wifi for 7 days or anything else. You must find your way)
open up a shell in the folder where your tar file is located
run odin4 -a vbmeta.tar
when it reboots, remove the cable from the device (it just needs about 3 sec to finish the flash of vbmeta)
delete userdata like described on the screen
completly set up device, skip what can be skipped and shut down the device
go to download mode via Vol. Down + Vol Up
bootloader state said "broken" now
download and extract the recovery zip and rename the recovery...img to simply recovery.img
Open a Command Prompt in the folder where the file was downloaded and TAR the file by running tar --format=ustar -cvf recovery.tar recovery.img
now flashing the recovery via odin4 -a recovery.tar
- it will immediatly restart the device once finished. Do not remove the cable. Make sure to immediatly hit Vol. Up + Power to boot into recovery mode. If you miss it, the device will reboot completly and you need to repeat this step.
once in /e/OS recovery, perform a factory reset and then it apply update
continue with the step "Install /e/OS" like documentated
