Welcome to the wonderful world of XDA;););)

If you ever need any help let me know Im no Dev but I know how to follow instructions and can take all the logs you want:p:p:p
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] mr3p:
As others have pointed out, after clean install with Gapps:

“There's an internal problem with your device. Contact your manufacturer for details.”

This appears on initial startup and after each reboot. From long ago I recall as similar issue which related to the /system/build.prop and the /vendor/build.prop values not matching. I also had a few crashes on initial setup but that seems limited to the setup app.

I don't have time to play with it now but see this solution which may work.

https://android.stackexchange.com/q...-your-device-and-it-might-be-unstable-until-y

update: I can confirm that copying the value from build.prop.system to build.prop.vendor (or opposite) for ro.vendor.build.fingerprint does eliminate the error. You can use MiXplorer to make the edit if you don't want to use adb. I am also seeing an alert that SELinux is set to permissive, which I now realize is ROM default as acknowledged by virsys. SElinux permissive notification can be disabled by toggle in Settings until this is addressed.

Hopefully virsys can include build.prop fingerprint mismatch in next update as the ROM is quite nice. :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Thanks for your contribution, mr3p. The fingerprint mismatch causes this popup, that's right. I don't like changing aosp code, I prefer to play around with the device trees. Fortunately, there was a simple fix for the device tree available. After applying the update, the popup disappeared. The only two goals we need to achieve in order to get official LineageOS support are SELinux and encryption. But as other samsung msm8916 devices struggle with these two issues, that's still some work. I'm new to all the android building stuff and "exploring" how to properly fix complicated errors is quite time consuming, even if there are step-by-step instructions on the internet. I worked especially on SELinux a long time, but enforced SELinux doesn't even boot and added contexts and rules aren't active in builds for some reason.. Time is limited, but I'm still working on this flat brick sometimes..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheMadScientist:
Our s8s we cant even root unless permissive.

which means we are limited by the factory binary builds to even achieve root,No unlocked bootloader.

and limited to a 80% charge because of the factory binary boot imgs

With a bit of work I got ps4 remote play to work absolutely wonderful on this tablet.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
No update here for a long time .. I'm sure you all waited for the December patch, but I was really busy with other stuff, so please excuse the delay.

To improve security, SELinux is now enforced. Please make a backup before switching to the latest build and report any errors in this thread.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Kawakigachi:
No problem, i will to make backup "16/11/2018 ROM LineageOS" in my TWRP 3.2.3-0 and I install and test "21/12/2018 ROM LineageOS 16". If error? I will talk you ;)

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
I'll take a look at it in a few hours. Removed the enforcing build for now.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] elwhiteboy01:
So virsys you got selinux enforcing on this ROM, but not on Oreo? Is that correct? And I haven't installed this pie edition yet, as I am still enjoying your Oreo aicp rom. I see people having problems with gapps, if I did install it, I would use microG again and not bother with gapps, just saying.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Oreo is discontinued. There shouldn't be any problems with gapps as long as you clean flash the rom and gapps immediately after it.

Hello. I have flashed my tablet with this firmware and am very pleased. Much better than stock firmware. but my microphone doesn't work. sound in the speaker works, and voice input does not work. On the stock firmware, everything worked well. I gave all permissions to applications with voice input but does not work. I apologize for my English, this is a google translator.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
The builds with _ENFORCING at the end of the name in the download section are SELinux enforcing. I'l take a look at the microphone later. I've migrated some audio related files to generic msm8916 OSS ones, maybe something went wrong there.

I have no any download progress notification...

Is there any solution?

Thanks!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
These problems can occur when the system is flashed dirty. The microphone has been fixed now. Maybe I'll return to AICP / other heavily customizable ROMs in the future. AICP is based on LineageOS, so these problems would be present there as well. The stock camera has a very bad pixelated view-finder for photos, I highly recommend to use OpenCamera or Google Camera, because this issue is limited to the stock camera app. Otherwise this tablet is pretty old and obviously not as fast as a flagship in 2019.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] DSD_CYRO:
Hey virsys. :)

Found your lineageOS 16 build for the SM-T555/gt510lte. Flashed it, booted it and all seemed fine except for bluetooth crashing every second. Used Root Essentials to disable it and the constant popup went away, along with all bluetooth capabilities. Also flashed the AICP version before that, but that had the speakers issue, hence why I tried switching. Anyway, there, bluetooth worked, but not the speakers. In LineageOS 16, speakers work but bluetooth doesn't. Always something, eh?

I am VERY new to flashing and rooting, so new that I must've missed something as I always need to flash the default pit file every time I flash something in TWRP in order to continue booting into the system. Can't find anyone else having that issue. But I digress. I'll see if I can grab a few logs for you if you want. Also willing to flash any version you put out, just need something, anything, instead of samsung's bloated and slow touchwiz-infested OS.

Sorry for a long-as-**** post, I tend to provide all information possible. A curse and a blessing I suppose.

thank you for this great rom! on a older build i could not install the netflix app, does the netflix app work on the latest build? ( build jan 11 2019 )
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
The two builds on my AFH account are testbuilds and not recommended for use on a daily driver. I don't own the LTE version of the Tab A 9.7, that's the reason why there is no official thread. I can't support the device properly alone. I tried to work together with some testers but that didn't went well. At the moment I have nobody who wants and is able to test these builds on his sm-t555 and I don't want to release builds on xda just because I guess that it should work. If somebody wants to maintain the lte version - please. But I can't do that on my own.

I'll do some testing with the netflix app. And welcome to xda [MENTION=4886425]revence1988[/MENTION] :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] DSD_CYRO:
Sad to hear that it didn't go well with the others. I'm willing to help out, send logs and whatelse, flash builds and so on. Just provide some builds and I'll try them and send logs etc. back. If you're interested, that is.

Hey Virsys,

After a clean flash the camera eventually just stops working or allowing any other apps to use it - any ideas? I've clean flashed quite a few times but the issue appears to be consistent.

Also, cheers for making such a smooth ROM ?

Edit: I'm on the 20190111 build
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] nodeboy:
Very nice ROM (lineage-16.0-20190111),

setup assistant FC'd a couple of times but finally went through. WLAN stable, didn't try BT. Screen on Time ~6-7h.

One thing i noticed, which made me temporarily switch back to my old ROM, was the inability to stream video from NAS- no matter which client i used.

No problem with youtube or browser videos...

I would happily go back to your ROM when this is fixed.

Hello Virsys,

first thanks for the custom rom - chapeau .

Only one issue: last release seems to have an Issue with sd card (see last Post from shein bo)

Last release (Febr.) has problems with my SD card - I returned to the previous one (Jan.2019)

- the system says under new release that the card is damaged and cannot be read - but it an be read under TRWP and also I am using the prevously release.

[MENTION=9329218]sheinbo[/MENTION] I couldn't even get the rom to install. Although I did use the latest build. With three attempts of wiping for a clean install and I get the same error code, I think I'll stick to the Oreo rom.

I will too not install LOS for T555, but try so: Download the firmware, the right button will press the unpack menu ( I recommend WinRar ), the firmware will be unpacked, go to the folder Meta-inf and subfolders com, google, android, there is our ill-fated updater-script does not give to flash this firmware, copy it to a convenient location, then I recommend to open notepad ++ ( Notepad will not work ), and edit it, namely, remove the line so that (line ui_print("Target: samsung/gt510ltex/gt510lte:7.1.1/nmf26x/t555xxu1cqj6:user/release-keys")) will be after removing the first lines at the top in notepad ++), then choose the file save as, choose the format all and save it under the name updater-script1. Now go to the same folder meta-inf and the corresponding folders (above) and delete the ill-fated script, instead insert updater-script1, rename back to updater-script ( to avoid error 4 in twrp ).

Very important: before saving updater-script1 it should be in unix format ( error 6 will be in TWRP otherwise ), find in notepad the phrase format of the end of the lines, it says that the file is already in it, but in fact it is not, change to any other, and again click unix ). Now there should be no error when installing the firmware.

Now select all the folders that are in the unzipped firmware and click create zip, by default it is better to rename the standard name of the old archive, and now install

Hi Virsys,

I'm looking at github to see how you fixed external audio for the SM-T550.

Am I looking at

https://github.com/VirsysElectron/android_vendor_samsung_gt510wifi

If yes, which commit got the external audio working?

Thank you.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] elwhiteboy01:
Okay can someone send a link for the proper twrp to install this rom? The previous link a few posts back put my device in Odin mode. And trying to install a twrp after that just gives a recovery bootloop. I had the pie rom working with ashyx twrp, but after I did a little setting up and when to flash magisk, it went back to a recovery bootloop. Virsys did you ever make a twrp like you said you were going to?

Update, I had the pie rom working with a different twrp, but I still had a recovery bootloop. I found virsys twrp and used it, but it couldn't read my external sd card. I literally had to start from scratch, I'm going to just use the Oreo aicp rom.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
What exactly are you trying to achieve? If you want to build your own version of android take the current device tree. Migrating my solution to other devices did not work in the past. I've fixed the whole audio framework by editing and importing my own mixer_paths.xml to /system/etc
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Have you used this version: https://twrp.me/samsung/samsunggalaxytaba97wifi.html ?

On my device my twrp is able to read the SD card. Have you converted the SD to expanded internal storage?

And what is the last Android version update you flashed from Samsung? You should have flashed their Android 7 update once.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
Virsys, thanks for replying. I appreciate your time.

I'm trying to help get the SM-T350 external audio work. The SM-T550 is the 9.7 inch A version. The SM-T350 is the 8.0 inch A version. Both were released at the same time and both share the same hardware. So I'm assuming the SM-T350 is the little brother of the SM-T550.

Thus, I'm hoping that whatever fix you did for the SM-T550 to get external audio working will give us a clue on how to fix the SM-T350. Your fix may not be 100% applicable to the SM-T350, but at least we have a general idea of where to look.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
Just to clarify please, I downloaded the SM-T550 and saw mixer_paths.xml in

/system/vendor/etc

I don't see a mixer_paths.xml in /system/etc

I also see you created audio_platform_info.xml in the /system/vendor/etc as well.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] elwhiteboy01:
Virsys, I've never had to convert my sd card to expanded internal storage. And I'm not going to now. And yes I flashed the nougat update a long time ago through Odin. Unfortunately, the stock rom is the only thing working right now. I can't use any twrp or it just does a recovery bootloop. And yes I tried the 3.2.3.0 twrp listed, did the same thing. This all started when I flashed the twrp some idiot posted a few pages back. I would recommend nobody click on that link. I just went into the stock recovery and wiped the cache. I'm about to flash a twrp again via Odin. Will update soon.

Update, clearing the cache in the stock nougat recovery rom worked. I'm now using twrp 3.2.3.0 with Android pie rom...cheers!

Oh and virsys, the problem with the SD card I fixed by downsizing from my 128gb to a 64gb. Not my first choice, but everything is working now.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
/system/vendor/etc, that's right. Maybe you have to set AUDIO_USE_LL_AS_PRIMARY_OUTPUT := true in your BoardConfig as well. But from that point you should test your builds with different audio routes.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Maybe it's a bad card then. I have a 128 GB card and it works as expected.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] elwhiteboy01:

And are you using some kind of third party lock screen app? I've never seen the lock screen look like that, just saying.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheMadScientist:
Try booting safe mode and see if it happens. If it dont its 3rd party
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] smolchy:
nope I'm not a fan of thirdparty apps, that change UI, like to have it in stock and fast.

I'm aware of all this, so I'm not using any of this. I have installed magisk just for using AdAway, the rest I have only offical apps from Play: Unified Remote, Remote Desktop, Trials Frontier, gMail and that is it. Installation was totally clean and wiped, with first updated TWRP to the latest version...

And yes, I'm on twrp virsys...

in other way, the ROM is badass, the tablet is smooth, working better than any other ROMs, just this lock screen...I have widget for Clock (stock) on the desktop...I notice, that the color of this error lock screen is usually blue, the same as the background of the Clock if you open it...so I'm thinking if it is trying open the clock in lock screen or something...it is weird :)
