It's just like Magendanz told the community already,

"Well, you just need to start with the kernel, vendor and product partitions for the SM-T515, and you should be able to use any of the system images from my custom ROMs. I've already built the recovery partition for you, and you could grab my custom kernel from that (which disables the Knox boot security features, but doesn't fix MTP). From there, however, it's all just troubleshooting...which is difficult to document."
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jurgenmmehja:
Thanks for the new release!

Do I need to clean flash or dirty flash?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AlmostIdiot:
Clean flash for last update
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
You might be able to get away without formating the data partition if you're coming from the previuos release, but that won't get you the fixes for PHH Device Settings. That involves a change to rw-system.sh, which only runs on first install.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] daljitbanga:
Thanks for the message on where we stand for t515. Just wondering where is your custom recovery and kernel maybe might get rid of the lag that we experience with stock.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Yes, it should work...but you'll have a vendor partition that's built for the XAR region. I would guess that the vendor partitions are practically identical between NEE and XAR, but you do run the risk that you'll see some strings in English.

Note that you could legitimately localize this custom ROM by pulling the "fixed" NEE vendor partition after running [MENTION=7187684]ianmacd[/MENTION]'s Multi-disabler and swapping it for the vendor image in my tarball. Just pull it with the dd command in TWRP Terminal, and then run "img2simg" to convert it to a sparse image. Note that there are changes that need to be made to Ian's script so that it runs on the SM-T510, but just send me a PM if you need that.

New build (20190810) posted today, based on [MENTION=1915408]phhusson[/MENTION]'s AOSP 9.0 v117 with the August security update and a bunch of fixes for Samsung devices. If you already have 20190629 installed, you can just unpack the system image and flash it in TWRP. No factory reset needed.

Hi guys when flashing in odin i get 'only official released binaries are allowed to be flashed (boot)' what can i do about that?

I realised that i have to flash the NoKnox first? But that means i have to downgrade to T510XXU1ASEF.

Can i ask you, i have to flashed the scrubbed kernel right? Is that the NoKnox file from this link: https://xdaforums.com/galaxy-tab-a/development/recovery-twrp-3-3-1-2019-galaxy-tab-10-1-t3934805 and should i flash twrp also?

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] spezialzt:
Hi guys.

First of all and as usual thank you to OP for given me the opportunity to use the stock experience an a Samsung device, always a pleasure.

Battery drain seems to be on Original Stock level. Charged it 15 hrs ago and streamed some videos over YouTube, display on-time shows me 9hrs 16min since the last complete loadcycle. 47% power remaining. Awesome!

Now to the doesn't work part...

I'm not quite sure , is it just me or is the rom sound compared to stock significant duller and quiter? While on Original stock Netflix, YouTube and Spotify had a crisp, loud and stereo like feeling to it. Now I'm missing something.

If you want I can provide some syslogs and demesg if you need them.

Have a nice day
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
My guess is that was a Samsung audio effects package that's not included in AOSP. When I switch to LineageOS 16.0, you'll get their AudioFX app that should be substantially similar.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] spezialzt:
Looking forward to this. Nice!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
If you've got a SM-T515, the latest Nexus Stock for that device is available here. Follow the same directions as for the SM-T510, but there could be more issues because I don't have a device for testing and they've used different partition sizes. This is really just for the truly courageous. ;)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ChangeToTower:
Nice - but the link is not working unfortunately..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Sorry, I pasted the wrong string. Should work now, though.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ChangeToTower:
Thanks, working now. Downloading at the moment and will flash according to your instructions in the first post.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ChangeToTower:
Ok, I could test it now. To keep a long story short: I have a running Nexus Stock, rooted with Magisk and EdXposed installed, on my SM-T515. Thank you so much, Magendanz. Just followed your instructions, but had some boot issue initially. Then I flashed your custom zip you were talking to implement in the other thread (sorry, I don't know remember the file name) and Magisk. Wiped data and factory reset, and it worked. Only issue I've found so far is that face unlock is not working. Further testing in progress..

Edit:

The file I mentioned was the multidisabler zip.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] d4dave:
Finally received my T510 today. It's already on the latest ASEF firmware and I was able to enable OEM unlock in developer settings. After a reboot I checked that OEM unlock was still enabled. So am I ready to try installing this rom as per the instructions in post #1? Or do I need to do something else to unlock the bootloader? Do I need to flash noknox first?

Edit: I got it installed successfully. Instructions were perfect and the bootloader unlock process was painless. Device ID registered and all looking good. Huge thanks to the OP for creating this. Keen to help test future ROMs.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] dlehmanusa:
I already Flashed this ROM and TWRP. It is running great so far. Thanks for all your work on this. I do have 1 question...I want to make a full backup in TWRP. Can anyone tell me which partitons I should check or uncheck before I make a backup? The "Boot" and "System" partitions are already checked off by default. Should I leave it as is or check off any others? Thanks.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
You can't use Ian's for the Galaxy S10 unmodified, but here's one that should work for the Tab A 10.1: multidisabler-t51x-1.41.zip

Thank you. How do I flash it? Isn't a ZIP for flashing through TWRP only?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
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.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
New build release today...

Change Log:

20200422:

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.

You are a legend!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] win32r:
Hello. You planned this rom for T515?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
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.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] win32r:
It is sad :(
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ckbcowboy:
[MENTION=903232]Magendanz[/MENTION] 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
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ckbcowboy:
[MENTION=903232]Magendanz[/MENTION], 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!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
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.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Freethefire:

Do you lose Dolby atmos? Can you tell me exactly what makes your experience better than stock. Thanks for your reply
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Boots!:
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.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
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.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Boots!:
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!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
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).
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Boots!:
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.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] massivekind:
Choose the csc file ( and not the home file) BEWARE OF DATA LOSS. After flashing the file, the Samsung boot logo should be back.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Boots!:
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.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] massivekind:
Good to hear :highfive:, no problem, I also started with not allot of knowledge. ( like everybody) :cool:
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] piro.lito:
HEllo,

i'm still getting the "Tablet's bootloader" warning message at boot. Can this be removed?

I'm using this tablet in car and it makes the boot time to increase. Can this message be removed and also some way to speed up the boot time?

Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
No, that's done entirely in the bootloader, and messing with the bootloader is very risky business (not to mention difficult, since we don't have source). One wrong move and the device is permanently bricked. All I've been able to do is reduce the warnings so that they don't sound so scary, which is just replacing bitmaps in param.bin.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] piro.lito:
And is there also an easy way to change the boot logo?

Since i'm using the tablet as my car screen would prefer to have the logo rotate, is it possible?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
The param.bin is just a .tar archive of .jpg files. Swap out the images you want to change.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] piro.lito:
But is it possible to do it without flashing the full rom again?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Yes. You can just create a .tar of the modified param.bin and flash it with Odin. You don't even have to compress it with LZ4 or include the MD5 checksum.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] piro.lito:
Ok, i uncompressed the param.bin and edited the logo.jpg.

Then i compressed all files again with 7-zip as a .TAR File.

Opened Odin 3.14.1, started the tablet in download mode, on AP choose the param.tar file, hit START but odin just crashed/closed.

Am i doing anything wrong?

---------- Post added at 09:24 AM ---------- Previous post was at 09:20 AM ----------

Ok, i figured it out.

I need to compress the param.bin as tar.

It's working now.. Thanks a lot.

[MENTION=903232]Magendanz[/MENTION] is there a way to enable the Adaptative brightness mode in this ROM?

Or take a chance and go for the oldest ?

I tried the newest stock.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] riverstyxxx:
Would not recommend this rom, at all. I used it for about four months because I was waiting for android 10 to mature and it was nothing but one headache after another. Among the many issues, the three significant ones were:

1. Changing tabs (the little square icon at the bottom) always resulted in the app resetting. For example, I'm browsing a reddit app on a specific subreddit, I'll be several pages down and either minimize it or press the square to change over, and check my gmail. When coming back to it, the reddit app would either be reset to the front page or reset to the top of the subreddit I was on.

2. About twice a week, some app would crash for reasons unknown but then it would work again. The problem was that after I either shut down or tried to restart the tablet, it was softbricked. I could hold the power button for a minute, nothing would happen. Plugging it into a charger didn't work, no response at all. It eventually turned on again after holding down volume + power but it would take forever.

3. Games would just stop responding to my touchscreen. No idea why.

This rom was poorly written, it needs to be retired. I was only using it because there was nothing else available at the time.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
This is a feature of Android. If memory is low, the OS will quit background apps and resume them when brought back to the foreground.

This sounds like the cold charge bug, which was fixed in March.

This is the first I've heard of any touchscreen freezing issue. I also have no idea why it would happen.

There is nothing "written" in this custom ROM. It's just the latest LineageOS 16.0 GSI (which I build for [MENTION=4467696]AndyYan[/MENTION]) with OpenGApps, a tweaked Pixel Launcher layout, custom boot animation & wallpaper, and fixes for cold charge & MTP. I do, however, offer a double-your-money-back 100% satisfaction guarantee. ;)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] riverstyxxx:
You are aware this tablet has a very nice processor and costs a lot, right? The memory was never low, always had several hundred megabytes to spare. I could be running a 1080p movie through vlc on a network share, while downloading an nzb at 50mbps and still have room. I've switched to other roms since then and it hasn't been an issue since. Cold charge bug? No. I would be playing with something, then the tablet pukes and recovers but after I shut down or try to restart, nothing happens and it becomes a brick for a while. At no point in time did I plug anything into a charger. The other one I forgot to mention: A few times a week, usually when it crashes, the wallpaper would reset itself to stock.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Now you've lost all credibility. :) Only 2G of DRAM is pathetically low for an Android device released in 2019, and the Exynos 7904 processor performance is mediocre at best. This is why Samsung has only released it on ARM32 architecture. But what do you expect for a 10.1" tablet selling for < $200 USD at Target right now?

Seriously, though, if anyone else is experiencing these issues, please chime in here. I'll happily pull the plug on this custom ROM, as [MENTION=6664399]riverstyxxx[/MENTION] suggests, but I suspect that this is not a widespread problem or I would have heard from other sources.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] boybill:
I use the AQ and it is fine. Not just fine, terrific.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] avalx:

This ROM is amazing! It has significantly the performance of my tablet. It is much speedier than Samsung's stockrom.

Thanks for putting so much time and effort into this wonderful ROM. I really appreciate your work.

Lastly, there's no pleasing some people. They don't understand you have created and maintained this ROM for free and in your time.

Yes I agree there are some minor bugs, but still a million miles better than the laggy stock ROM.

Be grateful and appreciative someone has spent then own time creating the ROM.

How to get Netflix and prime video to work?

After a long contemplation, I finally installed the ROM. With no doubts, it performs faster than the stock rom and feels much more polished than the samsung jittery mess.

I can't seem to get Netflix to work tho. I side loaded the latest version, it would launch fine but finally stuck on a unless loading screen when trying to play anything. anyone have solutions for it?

(For prime video, it would play fine in SD after installing Magisk without further tempering; if anyone know how to get it to stream in HD, it would be much appreciated)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
For Netflix, deleting /vendor/lib/liboemcrypto.so does the trick. I've added it to my build script, but for now you can just delete the file in TWRP.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
If your SD is 256gb then it must be exFat and the kernel doesn't support exFat. You need to install the Infinity kernel Version 2 for Android 9.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] xiaozi:
I did install the nexus android 10 version and infinity 3 for android 10. I format the sd and still can not see the card. I also used a 64GB card for testing.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I'm running the RR ROM with the Infinity kernel and my SD card is 64gb. But I replaced the 64gb card with a pre-formatted 256gb card with close to 200gb of data on it. I can read the data both in TWRP and booted to system with my file manager. One thing I noticed was that when I booted, it asked me to setup the SD card but I ignored that because I didn't want to lose the data already on the card. Have you tried formatting your card with TWRP and then ignoring the request to setup the card when you boot to system?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] xiaozi:
Thanks for your advice, I format it in TWRP and now it is working. One more question, Can you move storage to SD card for some of app? I know in android 9, that is doable.
