Thanks for working on Tab s2. Mine is model number SMT815Y, is this the correct model to try your rom on?
Thanks.
I made an update for this device, enjoy

Hi
Following my post, I found this one and download to give a try at you unofficial /e/ build.
Unfortunately, my Tab S2 device is looping at boot on /e/ logo (my data is MY data).
TWRP 3.6.0
Android Debug Bridge version 1.0.41 Version 32.0.0-8006631
on Linux Mint 20
For me it worked. e-0.9-n successfully installed on my S2 Tab 9.7 SM-T-810.
Any guidance how one can build a new unofficial build? I have some experience with building own unofficial e version but not for this device
The LineageOS dt has stopped at CM14.1 as seen here GitHub - LineageOS/android_device_samsung_gts210wifi.
But one of the 15 forks has been updated to 18.1 GitHub - universal5433/android_device_samsung_gts210wifi. You could start there.
Thanks a lot. So LineageOs is now to 18.1 What about e OS? I would build myself but seems to be difficult for this device
I favour the idea of just building Lineage first, perhaps at 17.1. This hopefully gives you a working roomservice.xml more quickly than waiting for /e/ to build. (Once that builds and works, just start an /e/ build.)
Proprietary blobs are reported troublesome for Samsung, but proprietary_vendor_samsung/gts210wifi at lineage-17.1 · TheMuppets/proprietary_vendor_samsung · GitHub look available at least at 17.1.
Where else might you think “difficult” ?

Once that is done, building LineageOS4Microg becomes very straightforward, and it’s relatively easy to add in the upstreams of /e/'s forked apps (K-9 Mail, Etar, QKSMS, NextCloud sync client and Notes, OpenTasks, DAVx5 and ICSx5), leaving you with pretty much the same functionality as /e/OS.
I’ve already made such a build for a couple of Android Q Sony devices, and I will be spending time soon doing it for the Sony devices which are currently stuck on Nougat. If When I get it working, I will make any manifests and scripts available to others so they can be used to build for other Nougat and Oreo devices which are being abandoned by /e/.

Cool thanks. That seems the way to go for the subset of Nougat / Oreo devices facing the chop where no Lineage dt forks can be found beyond CM14.1 like suzuran. Forks · LineageOS/android_device_sony_suzuran · GitHub.
Actually building /e/ as proposed by @ronnz98 but at say 17.1, may expose more light on where the difficulty to jump out of Nougat is not fully known to us.
I tried now to start building LineageOS 14.1 for this device but stuck with this error message… any ideas?

Building nougat/cm-14 /e/OS ROMs has been broken for a while unfortunately. I saw similar errors last time I tried to build one.
The last successful nougat build I made was back in June, using the v-0.21-nougat tag in my build. You could try that.
I also seem to recall that building LineageOS and Lineage-for-MIcrog for nougat broke around the same time, but I don’t have details and I may be wrong. Good luck!
ok thanks. Then I think I give up since non supported devices by Lineage are hard to build and my experience is limited. Hopefully more tablets will be supported by Lineage and hopefully a also at least one 8" tablet. I would love to see the Samsung tab s7 supported
@Deltadroid successfully builds custom ROMs for Samsung Galaxy S2 (T813 and T713) based on LineageOS 14.1, currently with Android Security Patch Level August 2022.
