It's in the TWRP topic. While I posted an update for the SM-T510 here yesterday for T510XXS3ATB4 (February 2020 Security Update), Samsung hasn't yet posted kernel source for T515XXS4ATB4.

- New private build of LineageOS GSI with April 2020 security patch.
- Updated to T510XXS3ATB4 kernel and vendor partition (February 2020 Update)
- Updated to latest OpenGApps (20200422), with private fix for Chrome issue.
No, I dropped the T515 a long time ago because it was impractical to build for a device that I didn't have. Maybe someone can convince Samsung to send me one, but they don't even sell them here in the U.S.
@Magendanz please tell me if what I want to do is just totally ridiculous!
First off, I'm a software engineer with plenty of experience, just none with Android development. I want to compile a version of this ROM (which works great, btw!) with _one_ line changed in the android source(USB_NEAR_IFACE_ADDR = "192.168.42.129") because I have 2 T510 tablets connected via USB tethering and I need them to each have a different IP
[edit] I did a lot more digging and figured out most of it. I'll make another reply with a more sensible question

@Magendanz, I actually figured out how to build everything, I now have a lineage-16.0-20200507-UNOFFICIAL-treble_a64_bvN.img file, but I don't know what to do with it.
I see the instructions in your android_device_samsung_gta3xlwifi repo README, but I don't understand where to clone your repo to.
Can you give me any pointers? Thanks!

Congratulations on your first LOS build!
First of all, the instructions in my android_device_samsung_gta3xlwifi repo are for building TWRP 9.0 on Omni. In theory you could use it to help build other AOSP-based system images, but I just use a GSI. You've now built your own LOS 16 GSI, and so you can simply flash it in TWRP to replace mine.

Thanks for an excellent ROM!
Just wondering if anyone else has problems with Netflix just streaming SD quality? Annoying as...
Cheers!

Do you lose Dolby atmos? Can you tell me exactly what makes your experience better than stock. Thanks for your reply
Nexus Logo still present?
Hello! Thank you very much for putting this together.
I decided to unroot my tablet and flash stock, I did so using ODIN and everything seemed fine however I still get the Nexus logo each time I boot up the device. It shows "Nexus" then "Samsung" and then the device boots as usual. How do I remove this Nexus logo? Did I fail to uninstall the custom ROM correctly?
Thanks again.

You just need to flash the original param.bin, which is in the BL tarball. It also might require a hard shutdown to take effect.
Thanks for the speedy response. This Param.bin file is located in the stock firmware MD5, right? as "param.bin.lz4"? I managed to get TWRP working, but I'm not sure how to flash Param.bin, could you direct me as to how please?
Thanks!

Yes, when you download the OEM firmware, you'll have several tarballs (.tar.md5) to match up in Odin (BL, AP & HOME_CSC). These should flash even with Samsung's VaultKeeper activiated (which is causing your error message right now). The BL tarball will include param.bin (compressed as LZ4).
Thanks again for the advice, but unfortunately despite using Odin to flash my stock firmware, the Nexus logo still persists at device start up. I must have really messed something up somewhere. I'm not really sure where to go from here. I don't think it's effecting the device in any way, it's just a rogue boot logo that won't seem to go away.
Choose the csc file ( and not the home file) BEWARE OF DATA LOSS. After flashing the file, the Samsung boot logo should be back.
Fantastic! I flashed BL, AP and CSC without USERDATA and it worked perfectly. In awe of your knowledge!
Thank you both very much for your time. I'll be sure not to jump into these things half-cocked in the future.

In the spirit of moving custom ROM development along for the 2019 Galaxy Tab A 10.1 [SM-T510/T515], here's one I just created based on the September 2019 Update and @AndyYan's LineageOS 16.0 GSI. It's very much a work in progress, but it should hopefully help blaze the trail for even better work.
Notes:
- The current process may require you to reset to factory defaults to remove file-based encryption. Remember to backup your data!
- Custom kernels are specific to OEM releases, and this one is based on the November 2019 Update (T510XXS3ATB4) for the SM-T510.
- The system is based on @AndyYan's LineageOS 16.0 GSI with the latest Stock variant from OpenGApps.
- Boot logo and default wallpaper is from my Nexus series of custom ROMs for Android TV, and I'm using the Pixel boot animation with black background.
- Stock recovery will be replaced with my latest TWRP build for the SM-T510.
- I've dialed back most of scary bootloader warnings and Knox Security branding from the boot sequence.
- This is unofficial and unsupported, so the usual caveats apply. Since we don't flash the bootloader, you should be able recover from any problems...but nothing is guaranteed.
Not working:
- Support for file-based encryption
Downloads:
SM-T510:
- Nexus_Stock_LP_T510XXS3ATB4-20200422.tar.md5 (Odin tarball)
- Nexus_Stock_LP_T510XXS3ATB4-20200422.zip (TWRP update)
- No longer supported (since I don't have hardware for testing), but archives are posted here.

5Another new release today, fixing a couple of chronic bugs in the GSI.
Change Log:
20200405:
- Fixed Double Tap to Wake feature (enabled in Phh Treble Settings).
- Fixed crash on first two attempts to launch Phh Treble Settings.
- New private build of LineageOS GSI with the above fixes (#663 & #1228).
- Updated to latest OpenGApps (20200404), with private fix for Chrome issue.
Note that the fixes require a clean install to take effect, since one element is implemented in rw-system.sh...which only runs on initial boot.5
Yes, I'm trying to build an unofficial LineageOS 16.0 release, but am struggling with some build issues. The primary goal is to deal with the Play Protect device certification (but I definitely won't pass SafetyNet). Eventually, I'll also get to fixing MTP.
