FINALLY got my source working, after a few frustrating derps on my part. Linked will be the changelog for Lienage, but nothing for our device. They've made changes to our Taimen tree, so there's a positive. This build is updated to the latest July patch, and you will not get any vendor mismatch thing. I made sure to fix that issue before even posting this. 8.1.0 (OPM2.171026.006.H1, Jul 2018) from the Google Gods.
I completely started over and flashed that firmware before flashing my Lineage build. No idea what will happen if you update, but I'm sure the firmware will complain. Vendor mismatch and TWRP might encrypt. I didn't just update Vendor image and flash a build that's on July. Root is working and Flash Kernel is too Stock kernel is forked from Carbon's ROM. TWRP seems to be decrypted (no passcode, fingerprint, etc)
I AM NO DEVELOPER! I just compile from Lineage's source and bless the community with an updated build! I have an Iphone (and Pixel 2XL), so I will try to keep up with any changes from Lineage. Maybe a weekly update, if I don't kill my source again LOL! OH!! Do NOT setup Google Now via setup wizard because you first need to update it via Play Store! Then you can hold down the home button and configure "OK Google" Cellular data should work, but I have my SIM in an Iphone, and I'm too lazy to swap.
https://www.lineageoslog.com/15.1 <---Changes of Lineage
https://developers.google.com/android/images <--- Factory Images (H1, regardless if you have T-mobile)
https://www.androidfilehost.com/?fid=5862345805528049535 <--- Current build
https://forum.xda-developers.com/pixel-2-xl/development/taimen-flash-kernel-1-00-t3702057 <---- Flash Kernel
Edit: Looks like restoring JUST data from an old Lineage build should be okay. You'll have to update all your apps VIA Play Store, but that's if you're as lazy as I am, and don't wanna restore all your apps
This is great! I'm running this now, only bugs I think are worth noting are related to the Google Camera, it's crashing at launch, but other camera applications work fine. Bluetooth works but I'm having trouble pairing an android wear device.
Thank you for compiling this, I'll keep testing new builds if you keep posting them!
First of, my apologizes to @RaymanFX , as I unintentionally hijacked the original thread. Obviously that was not my intention. I apologize, sir!
So, that camera issue is fixed, along with "now playing" working. I think it was due to jumping around with manifests, in hopes to stay current. I know the Taimen tree is current and Wahoo is a bit behind. I think I will try learning how to merge fixes and staying up to par with LineageOS. I tried to Frankenstein it. I really have a good friend, @deedwar to thank for this build. I kept having crashes at the start of the setup. I asked if he could help me and build Lineage, and he did just that, with Lineage's official trees.
I realized that I probably had to reflash factory images to get it to boot. I realized this, after I couldn't boot another ROM.
So what can I provide, moving forward?
- Well, an apology to Ray. Look, I'm not that type of guy to steal the spotlight. I understand the need for a separate post
- Compile a build when I notice changes to our device.
- Try to figure out how to fix things, or at the least, merge bugs fixes via a few bug tracking sources.
- Make a github (well I have one) but that has changes to whatever I may do.
- See if I can include Lineage's setup wizard without conflicting with GAPPS that are built in. Couldn't produce a build without GAPPS, as when you go to flash them, it won't stick.
I am simply a builder, if that's the right term aha. I just sync and build. No fiddling with folders or coding, as I don't know how to.
So, without further delay: Here goes the current build!
https://www.androidfilehost.com/?fid=5862345805528056608
July fingerprint
No vendor mismatch
Now playing and camera fixed
Android 8.1.0 r41
Up to date with Lineage's sources
GAPPS built in. You'll have to hold the home button to setup OK Google because it's not part of the setup.
@draymond1987
Thank you for sharing.:good:
Waiting for two builds to finish, which I'll post, tomorrow. Updated with latest Lineage changes. Seen they did something to our device tree. Can't see any commits that happened, soooo ¯\_(ツ)_/¯
It looks like the usual things. Code clean up, updates to certain things in the build. Like I said, I just sync and compile, so I am a bit oblivious.
One build is gonna be compiled with Clang and have Flash Kernel baked in, if all goes right!
Other build is just straight up Lineage and it's changes. Oh, and the kernel is forked from Carbon. I'll obviously give credit once the builds are up. Don't want to @ somebody and then the build doesn't work. That would be rude, in my opinion.
Thread closed as per OP's request.
Resurrection Remix Oreo
If you're not familiar with Resurrection Remix (RR), it's a very customizable and feature rich ROM. It's packed with some many great features like a notification ticker (like in the good ol' Kitkat days), styling changes, custom gestures, and more! RR is based on LineageOS. This is a build originally developed on by (russel5), but abandoned in favor of AospEx and Pie projects of his. Personally, I'm not a fan of the direction taken in Pie and will be sticking with Oreo. I'll be developing the rom further with features, bug fixes and enhancements. Any suggestions or bugs should be opened as an issue on the Github.
Please report any issues you have on the Github. The issue tracker helps me keep organized and on top of stuff.
Downloads
GitHub
Installation
1. Download firmware zip
2. Download OpenGapps/MicroG/Whatever
3. Push to phone
4. Reboot to recovery (recommend TWRP) and do a full wipe
5. Flash RR then whatever else after (Gapps, ect)
6. Reboot
7. ???
8. Profit
General Info:
If you have issues with the camera being green, make sure you update your firmware to the most recent Oreo one via newflasher. I will update this with information regarding this. It's been months since I did it so I need to remember and hunt the files down I used (which is hard since my last computer died and I switched to Linux). I'd backup your Drm keys before doing anything if you do.
Exclude when flashing:
* fotakernel.sin
* kernel.sin
* simlock.ta (if you have it)
* system.sin
* userdata.sin
* vendor.sin
Forced encryption is disabled. If you want it make sure to flash the boot img attached. Many users have bootloops so use at your own caution. To flash use fastboot flash boot boot.img

Yes, very good rom but i find out on androidfilehost about half year, so old.
USB tethering doesnt work.
Plenty of functions.
Stable, fast, no lags, pretty battery acceptable, more than 1 day of battery life.
Display options from stock, stock camera works very good.
I think, we need upgrade RR to 7 or 8.
I am using it now for about week and its very good as daily.
And at this moment its way better than Q roms.

You can't find the most recent version of the rom on AFH, I had to hunt it down from some random forum and the most recent one before that was unstable so wanted to get it out there for people to have. I really like RR. I'll test tethering, I thought it was fine but haven't really used it. Maybe I'll mess with 7 or 8 someday after I have this one developed alittle. I personally don't have any interest in Pie+.
Edit: USB tethering works fine for me. Must be an issue with your computer. I'm using Kubuntu 18.04 and works perfectly.

I am using Windows 8.1, but in other roms like stock or PE 10 USB tethering works. I push that on and no reaction in computer - networking.
If will be Havoc OS 2.x or BaikalOS, ill start interest in pie, because i had these roms in Mi Mix 2 and they was best. Havoc in general, can be compared with most functions with RR, Baikal from russia brats in battery life, performance and simplicity.
Idk if they dont arrive to XZ1c, but pie i liked was stock, Oxygen, Miui (with some bugs, but with future).
Still, oreo and nougat roms are older, but better in most things except mentioned roms.

No idea, it has to be your computer I'm guessing. Make sure you're running the most recent version since that other versions found on the other thread is very buggy. Noted on them.

No idea, can't remember testing out the Pie CrDRoid on here. I'm not a fan of Pie+ so it didn't interest me. Should test and report in, looks like they are similar being LOS based with decent amount of customization. CrDroid has signature spoofing, but I'm making a build with that added in for RR as I type. But yeah, let me know and what other features that CrDroid has that looks cool.

Hi, i have tested update of this rom and found out 2 system bugs.
First thing - bootloop. I flashed it like usually with newest BitGapps arm64 8.1.0 v15 and magisk. BitGapps caused bootloop. Clean install with only magisk booted, but magisk app not installed, so i had to install Magisk Manager manually, root installed.
Second boot into recovery and flash BitGapps caused no google store app, like before, so i flashed MindGapps and it works.
It is mine problem, i using alternative gapps but good to notice.
Sometimes not smooth, torn animations. More often than older build.
Red blinkings: Right after successful boot, after some clicks i see weird red blinkings on display. Something similar like in developer options turn on display blinkings after stress GPU/CPU but this happen in random time and is not turned on. Is little bit enyoying, its not happened in older 2018 build.
So my decide will be flash again .228 firmware and stay with Havoc OS, now i used version 3.8 for month and i can say, now is android 10 in lilac flawlessly done. I like more older Oreo UI but fix issue with blinking and i will be your satisfied user.
Thank you and best regards.

What's special about Bitgapps? That's really strange, can you grab a log on boot using adb? If not, go to https://github.com/hockeymikey/android_device_sony_lilac/issues and make an issue and help me track it and I'll get around to testing it. It'll help keep in touch with you and solve it especially if for some reason I can't recreate it for some reason. I got that red outline too and I thought it was just me. It went away for me so might be temporary on the initial install. If you could create an issue for that too on the previous link so I can keep you updated for that too.

So I did some testing. The red blinking is gone, that fix will be included in the next release (which includes signature spoofing and updates so a few system libraries like base, native and lineage-sdk). BitGapps doesn't cause a bootloop for me. It was kinda buggy, which is odd and crashes. I'll see what I can find for it. Magisk works fine for me. Make sure it's the most recent version but I was using old versions too as well as new so I don't know.
Hm, with usb-debugging enabled, it dont ask for permission and dont save the adb-key, so u arent able to adb into twrp. But ADB to the booted device works. Anybody else got this?

That's a TWRP reason. Whoever built it disabled adb in it. I repackaged twrp to allow adb for myself, I can share it if you want.
This will be nice
And... i get this red-frame too if some higher cpu-usage happens. What did u do against it?
Encrypting the device ends in a infinity-loop at the "Encrypting... time remaining 00:00.."-Screen.
Maybe i missed something (tried with and without the boot.img for force-encryption)?

I think this is the correct one, let me know if not. Red frame is an issue I caused with how I built it, building it as a dev build not production. It's fixed on my device. I'll eventually get a new build out, I've been waiting to get OpenDelta done for OTA updates first to streamline the updating process. Maybe I should push one out sooner since the build on here I don't think is really that usable while my phone one I'm using daily. I haven't tested encryption honestly. I'll have to look into. If you could make an issue on github with every little detail to help me track and fix, that'd be cool.
Hmm, same problem -> adb devices -> unauthorized
And there is no dialog for accept/store the ADB-Key if u plugin the PC for the first time.
So.. i was using newflasher to flash the stock oreo rom and guess what... the stock rom does the same... so if u flash the stock rom (47.1.A.16.20) without remove any files from the stock-rom-directory and the adb_key still exists... where can it be?
BTW: i can access the stock-rom with adb add the first start at the "Welcome"-Screen... but twrp cant find/use the key which is stored $somewhere
I'm trying to build for a device that has no known Android 10 device trees that I can find. I think I fleshed out the trees pretty well by following some sister/cousin devices and extracting a lot of stuff from the rooted phone itself, but my build fails at 2% due to a missing output file. The missing libdss.so file should be built as part of the kernel (whose source I have), but the build clearly isn't happening (or isn't happening in time to be recognized by the build system.)
I tried to build the kernel as a standalone module to see what might be wrong, and in trying to do that I can't seem to resolve all the issues with dependencies for cross-compilation to arm64. I've built for devices with existing trees by cherry-picking what I needed, but I've never built for something from the ground-up like this. I don't want to make the ROM with a pre-built kernel as the end-goal would be to become official. The attached image is the exact error I'm receiving, and the following links are to all of my source repositories that I'm using in addition to the Lineage17.1 base. Any help would be appreciated. I work as a full-time dev by day, I don't mind slogging around in some code if that's what I takes, I've just reached the end of my troubleshooting knowledge here and am not sure what the next step might be.

This ROM is ONLY for SM-T560NU, NOT SM-T560. I CANNOT make a SM-T560 build as they are different CPU/SoCs.
PLEASE BEFORE YOU decide to try this rom, you MUST read all of post 1, 2, 3 and 4 (about 10 minute read). If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.
I am not responsible for lost data, identity theft, lost money, security vulnerabilities, bricked devices or any other hardware or software malfunctions that comes as a result of flashing this rom.
BACKUP YOUR DATA AND OLD rom BEFORE trying my rom.
If you are NOT an expert in using fastboot, adb, odin, heimdall, twrp, DO NOT use this rom. You must know how to use these tools to revert back to your old rom.
If you are new to flashing custom roms, do NOT attempt this.
If you need your tablet for work and something important, do NOT flash this rom. This rom could result in a bricked device or boot loop or non booting device or you not being able to revert back to your old rom.
What works
1. bluetooth
2. wifi
3. brightness
4. external audio
5. GPS
6. audio through headphone jack
7. audio over bluetooth
What doesn't work
1. Camera. The stock camera app video recording doesn't work. Use Simple Camera 5.3.1 from https://f-droid.org/en/packages/com.simplemobiletools.camera/ . I have no plans to work on camera.
2. selinux is permissive. I have tried to make this build enforcing for weeks, but when I do, the OS doesn't boot and there is no adb logcat output despite making an "eng" build. Without adb logcat output, it's virtually impossible to determine what is wrong and I'm not spending anymore time on it. If having enforcing mode is important to you, use my 18.1 builds.
3. keyboard bug workaround. When prompted to enter something like a Bluetooth pin or text based password, sometimes the keyboard is not shown on the screen or off screen. The workaround is to goto settings, system, languages & input, on-screen keyboard, Android Keyboard (AOSP), appearance & layout, theme and choose "Material - follow system settings".
This keyboard bug is a LineageOS bug as per
https://review.lineageos.org/c/LineageOS/android_packages_inputmethods_LatinIME/+/325438
4. gapps. Some of you require gapps for whatever reason. I use Aurora Store for my purposes and thus have NO KNOWLEDGE of the current state of gapps.
There are various gapps projects (at least 5 in 2022). Each has pros and cons. It's your job to do the research and find a suitable gapps project. I suggest you allocate at least a couple of hours doing your own research. My rom works by itself fine without gapps. DO NOT talk about gapps in this thread. As a courtesy to gapps users, if you want to talk about gapps, I have opened a new thread at
https://forum.xda-developers.com/t/...m-t35x-sm-t550-sm-t560nu-and-sm-p550.4479285/
so you may discuss gapps wrt to the msm8916 platform. I will NOT be participating in that thread as I do NOT use gapps.
Thanks
1. LineageOS team for source code.
2. Kyle Harrison
- looking through the adb logcat and suggesting that my binder code was too old to work with Android 12's keystore2 code
- for the graphics and legacy camera patches to allow msm8916 to work with Android 12
- for his Motorola LineageOS 19.1 device trees so I could use his patches as a template for msm8916
3. @tarkzim
- adding back audio hal 2.0 and legacy camera hal 1.0 into the LineageOS trees
- helping me think through the msm8916 random reboots which was due to the TCP/IP patches
- maintaing and updating his repos so I can study them for learning purposes
4. pre ALPHA testers @RDS5 and @Sigster for willing to test pre ALPHA builds and leaving feedback.
FAQ - I spent hundreds of hours building this rom. It was frustrating process from Nov 2021 to Aug 2022 running into bug after bug. The least you can do is spend a few minutes reading everything before posting.
Q1. Where are the source and kernel source files?
A1. The kernel source files are at
https://github.com/retiredtab/android_kernel_samsung_msm8916
The device tree files are at
https://github.com/retiredtab/android_device_samsung_msm8916-common/tree/lineage-19.1
https://github.com/retiredtab/android_device_samsung_gtelwifiue/tree/lineage-19.1
https://github.com/retiredtab/device_samsung_gte-common/tree/lineage-19.1
The vendor tree files are at
https://github.com/retiredtab/vendor_samsung_gtelwifiue
https://github.com/retiredtab/vendor_samsung_msm8916-common/tree/lineage-19.1
The manifest.xml (or roomservice.xml) and build instructions for 19.1 are at
https://github.com/retiredtab/LineageOS-build-manifests
Q2. Is this ALPHA rom suitable as a daily driver?
A2. It can be depending on your requirements. I can't test every app so you try it yourself to see if it's suitable. I've been using this rom myself since mid March 2022 with no major issues. I suggest you do a clean install, see FAQ 11, and flash this 19.1 ROM BY ITSELF (no gapps, magisk, etc) and see if you like it. If you do like it and want to add gapps then see FAQ 12.
Q3. What if my app, xyz, doesn't work?
A3. If your app doesn't work, then go back to your old rom.
Q4. Your rom is laggy and buggy.
A4. If you find the above, then go back to your old rom. There's only so much software can do on a 2015 budget level tablet. Remember a budget tablet will have the slower SoC/CPU and less DRAM than a top of the line model. Your tablet will also run slower when you use gapps. You can run a lot of software without using gapps. Research fdroid, newpipe, Aurora store etc.
Q5. What TWRP should I use?
A5. You MUST use TWRP 3.5.2_9. Get it from
https://sourceforge.net/projects/retiredtab/files/SM-T560NU/TWRP/
Q6. Why should I use this rom?
A6. If you don't like this rom, then don't use it.
Q7. Will you offer monthly updates with security patches?
A7. I will try to offer monthly security patches, but that all depends on if I continue to have high speed Internet in the future.
Q8. Can you help me? I'm a newbie. Can you provide step by step instructions?
A8. I don't have the time to help newbies, so please do your own research. There are lots of tutorials, videos, etc on how to flash roms. Newbie questions must be posted in the Questions and Answers forum, not here.
Q9. Can I report a bug with respect to the rom?
A9. Yes, but you need to supply the following information. If you don't, I won't look at it.
You must provide an adb logcat of the problem and tell me how to reproduce it. Note I will not be downloading any apps that require money or an userid/password. For example, if you have problems with Netflix, I cannot help you since I don't have a paid subscription. If you use some app that requires an userid/password, I cannot help you as I'm not willing to create another userid/password even if it's free.
To get a logcat, open up a terminal window.
Code:
# clear the logcat first
adb logcat -c
# start logcat trace
adb logcat > problem.txt
# reproduce problem

Q10. Will you still build 18.1 for this device?
A10. Yes, for rest of 2022, but I will make a decision in January 2023 on how 18.1 and 19.1 will be maintained. If you like to help by building 18.1/19.1, please let me know.
Q11. Do I need to erase everything and format my data?
A11. Yes, you MUST erase all the partitions (system, data, dalvik/art cache, cache) using TWRP and MUST format your data before installing 19.1 when you are coming from stock or an earlier version of LineageOS or from another custom rom. If you get stuck at the boot animation for more than 5 minutes, it's likely because you didn't follow the instructions I just wrote. Dirty flashes from stock, other custom roms or older LineageOS versions are not supported and not likely to work.
Q12. What gapps should I use?
A12. I don't use gapps anymore. I use Aurora Store. As of Nov 6, 2021, I no longer make recommendations on which gapps to use as your mileage may vary.
Let me by crystal clear. YOU NEED TO DO YOUR OWN HOMEWORK selecting between the various gapps offered. There are 5: opengapps, nikgapps, mindthegapps, flamegapps and bitgapps. Each one will have it's own installation instructions. The only recommendation I will offer to use the SMALLEST version of gapps.
Don't be surprised that whatever gapps you use might have problems like "Just a sec", voice not working, updating google play store please wait, etc. These are NOT problems of the OS as the OS will run fine without gapps. These are gapps problems and you must ask in the gapps forum why it doesn't work.
In addition, some of the gapps may not install properly when using TWRP and say "cannot /mnt/system". For those cases, please use the LineageOS recovery.img you can download from
https://sourceforge.net/projects/retiredtab/files/SM-T560NU/LineageOS-recovery/
By flashing the LineageOS recovery.img, it will overwrite the existing TWRP and you will get a different UI.
Q13. I'm having problems with gapps, can you answer why it's not working?
A13. I WILL NOT answer any questions regarding gapps. This thread is about the rom, not gapps. Android does not depend on gapps in order to work.
Questions about gapps, for your courtesy, should be asked at
https://forum.xda-developers.com/t/...m-t35x-sm-t550-sm-t560nu-and-sm-p550.4479285/
Q14. Why isn't my post answered or ignored?
A14. Questions already answered in the FAQ will be completely ignored. Again, I do not use Windows OS or gapps.
Q16. What speed up/optimization tips do you suggest?
A16.
1. Turn off animations. Go into developer settings, scroll down to the drawing section, and set window, transition and animator scale all to "off".
2. If you don't have a google account, don't install gapps. Use Aurora Store to get your apps as you can get all the same apps from the play store using an anonymous login.
3. Dont' run more than 2 apps at the same time. You can probably listen to music in the background and use a web browser at the same time, but don't expect great performance from a 2015 entry level tablet.
4. Use a web browser like Brave that has built in adblock and privacy features.
5. Use newpipe to watch your streaming content. It has built in adblock so you don't have to watch forced ads.
6. Look for apps that are open source, ad free and lightweight.
7. Remove all unused quick setting "bubbles" from the quick pull down menu. I only need and have 6.
Q17. Does this rom support Magisk for root?
A17. I don't use Magisk myself so I don't know and Magisk is always being updated to fool Google's certification process. Others have reported Magisk as working, but I won't answer any questions regarding it.
Q18. Will this rom ever become official?
A18. With 19.1, legacy devices like ours will NEVER be official due to lack of ebpf support. See https://lineageos.org/Changelog-26/
Also, I don't want the responsibilities that come with being an official maintainer.
Q19. What is the difference between this rom and others?
A19. This rom tries to be pure LineageOS with little to no modifications.
Q20. Will there be any major 19.1 code modifications in the future?
A20. I don't anticipate any major modifications. There may be some small bug fixes and minor code cleanup, but all the hard work in getting the rom up and running and fixing all the major bugs have been done completed. This doesn't mean the code is perfect or well organized, but I won't be doing any major changes now that 19.1 is working.
Q21. Why did you fork the device and vendor trees for 19.1?
A21. The msm8916 repos seem geared towards phones and sometimes do not work or cause boot animation loops for tablets so I decided to fork their repos. In other words, what's deemed as msm8916-common code isn't common to all devices.
In addition, since I'm building SM-T350, SM-T357W, SM-T550, SM-P550 and SM-T560NU (all use the same msm8916 code), it seems easier to maintain all of them if I can control my own code repos and not worry if my changes affects the phones or not.
I have completely decommonized and rearranged the 19.1 msm8916-common tree so it's easier for me to maintain and build.
Q22. Can you build a variant of this device? For example, a LTE or S-pen version.
A22. If I don't physically have the device, I cannot and will not build it unless I can boot and test it myself. Even then, there's no guarantee that I can get those variant features working.
Q23. Can I load this rom on a variant devivce like LTE or S-pen version?
A23. The rom is built for the device explicitly listed. If you are an advanced user and understand TWRP, adb, odin, heimdall, you can try loading it on a LTE or S-pen variant by modifying the updater-script, but it may cause a bricked device, bootloops or non functionality of LTE/S-pen. You have been informed and warned!
Q24. What major code changes are in 19.1 vs 18.1.
A24.
- iptables has been removed in favour of ebpf
- keystore v1 has been replaced with keystore v2 which requires that the binder calls have some built-in security
- audio hal 2.0 has been deprecated
- legacy camera hal 1.0 and snap app have deprecated
Q25. I don't like the taskbar, how do I turn it off?
A25. Choose settings, type task into the search bar. Choose enable taskbar and disable taskbar. This will leave the on screen nav bar. If you want to disable that, go to settings, system, gestures, system navigation, gesture navigation.
Q26. Will this run on the SM-T560 or SM-T561?
A26. No, the SM-T560 and SM-T561 use a different CPU/SoC. The SM-T560NU rom will NOT work on SM T560/SM-T561.
Q27. Okay, I understand the consequences and that this is ALPHA rom and willing to take the risks outlined, now where can I find the rom?
A27. You can download it from https://sourceforge.net/projects/retiredtab/files/SM-T560NU/19.1/
NOTE: All builds that I upload have been personally tested on my device to boot and function as described in post #1. Having said that, there's still a chance it won't work on your device due to human error, your configuration, your apps, etc. If it won't boot, always start with a complete wipe of everything and format your data in TWRP. This is known has a clean install. Backup your data before a clean install.

Works great, thank you for your hard work.
My only problem so far is getting Dropbox to work in Mixplorer which I had no problems with in 18.1, but that could be unrelated and there's a way around it either way.

This ROM is ONLY for SM-T560NU, NOT SM-T560.
PLEASE BEFORE YOU decide to try this rom, you MUST read all of post 1, 2, 3 and 4 (about 10 minute read). If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.
I am not responsible for lost data, identity theft, lost money, security vulnerabilities, bricked devices or any other hardware or software malfunctions that comes as a result of flashing this rom.
BACKUP YOUR DATA AND OLD rom BEFORE trying my rom.
If you are NOT an expert in using fastboot, adb, odin, heimdall, twrp, DO NOT use this rom. You must know how to use these tools to revert back to your old rom.
If you are new to flashing custom roms, do NOT attempt this.
If you need your tablet for work and something important, do NOT flash this rom. This rom could result in a bricked device or boot loop or non booting device or you not being able to revert back to your old rom.
What works
1. bluetooth
2. wifi
3. brightness
4. external audio
5. GPS
6. audio through headphone jack
7. audio over bluetooth
What doesn't work
1. Camera. The stock camera app video recording doesn't work. Use Simple Camera 5.3.1 from https://f-droid.org/en/packages/com.simplemobiletools.camera/ . I have no plans to work on camera.
2. selinux is permissive. I have tried to make this build enforcing for weeks, but when I do, the OS doesn't boot and there is no adb logcat output despite making an "eng" build. Without adb logcat output, it's virtually impossible to determine what is wrong and I'm not spending anymore time on it. If having enforcing mode is important to you, use my 18.1 builds.
3. keyboard bug workaround. When prompted to enter something like a Bluetooth pin or text based password, sometimes the keyboard is not shown on the screen or off screen. The workaround is to goto settings, system, languages & input, on-screen keyboard, Android Keyboard (AOSP), appearance & layout, theme and choose "Material - follow system settings".
This keyboard bug is a LineageOS bug as per
https://review.lineageos.org/c/LineageOS/android_packages_inputmethods_LatinIME/+/325438
4. gapps. Some of you require gapps for whatever reason. I use Aurora Store for my purposes and thus have NO KNOWLEDGE of the current state of gapps.
There are various gapps projects (at least 5 in 2022). Each has pros and cons. It's your job to do the research and find a suitable gapps project. I suggest you allocate at least a couple of hours doing your own research. My rom works by itself fine without gapps. DO NOT talk about gapps in this thread. As a courtesy to gapps users, if you want to talk about gapps, I have opened a new thread at
https://forum.xda-developers.com/t/...m-t35x-sm-t550-sm-t560nu-and-sm-p550.4479285/
so you may discuss gapps wrt to the msm8916 platform. I will NOT be participating in that thread as I do NOT use gapps.
Thanks
1. LineageOS team for source code.
2. Kyle Harrison
- looking through the adb logcat and suggesting that my binder code was too old to work with Android 12's keystore2 code
- for the graphics and legacy camera patches to allow msm8916 to work with Android 12
- for his Motorola LineageOS 19.1 device trees so I could use his patches as a template for msm8916
3. @tarkzim
- adding back audio hal 2.0 and legacy camera hal 1.0 into the LineageOS trees
- helping me think through the msm8916 random reboots which was due to the TCP/IP patches
- maintaing and updating his repos so I can study them for learning purposes
4. pre ALPHA testers @RDS5 and @Sigster for willing to test pre ALPHA builds and leaving feedback.

Thank you for this ROM. Can you recommend a good media player for this ROM? I've always used VLC, but VLC has no audio on this ROM (Gallery can play videos with audio just fine). I'd like to have a decent media player. I'm using Aurora like you recommended.

Thank you for the info. The audio output sort of fixed the issue, but the sound cuts out for a second every now and then when playing a video file, so there seems to be an issue still.

Do you think a resolution of a video file should affect that at all? Before I upgraded to this ROM, I was on Lineage 16, and my tablet couldn't handle 1080p files, so I was only watching 720p. With this ROM, it can play 1080p fine (no issue with the native Gallery player), but when I play 1080p video with VLC, the sound cuts off momentarily here and there. If you have any suggestions, I'd very much appreciate it.

The video I was watching is 1080p (h.264) with audio aac encoding. It actually played 40 minutes after I wrote the initial reply with no audio dropouts.
I suggest you look for a DRM free 1080p video somewhere on the Internet that's public domain and shows this problem so I can download and see if it happens on my tablet.
Also, download an app called MediaInfo (8MB file) by MedaArea.net from Aurora Store. It's ad-free and contains no privacy trackers according to Aurora Store. Use that app to see what audio encoding is being used in your 1080p video.
If there's no obvious answers to VLC dropping audio, I guess you will have to find another player if native Gallery player works fine.

those use a spreadtrum SoC (sc8830) and the source code for their kernels isnt up to date, and the latest port was android 7.1.2 however whoever ported it violated the GPL and didnt release the source code, so the most recent i could find for the SM-T560's kernel is this
device tree, vendor.
the T560NU however has much better community support as it uses the MSM8916 SoC, so thats why this rom supports it.
This ROM is ONLY for SM-T560NU, NOT SM-T560. I CANNOT and WILL NOT make a SM-T560/SM-T561 build as they are different CPU/SoCs.
PLEASE BEFORE YOU decide to try this rom, you MUST read all of post 1, 2, 3 and 4 (about 10 minute read). If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.

FAQ - I spent hundreds of hours building this rom. If you think it's unreasonable to read this FAQ, then don't use this rom. Thank you.
Q1. Where are the source and kernel source files?
A1. The kernel source files are at
https://github.com/retiredtab/android_kernel_samsung_msm8916/tree/lineage-20.0
The device tree files are at
https://github.com/retiredtab/android_device_samsung_msm8916-common/tree/lineage-20.0

https://github.com/retiredtab/vendor_samsung_gtelwifiue/tree/lineage-19.1
https://github.com/retiredtab/vendor_samsung_msm8916-common/tree/lineage-20
The manifest.xml (or roomservice.xml) and build instructions for 20 are at
https://github.com/retiredtab/LineageOS-build-manifests/tree/main/20/msm8916
Q2. Is this ALPHA rom suitable as a daily driver?
A2. It can be depending on your requirements. I can't test every app so you try it yourself to see if it's suitable. I've been using this rom myself since mid Jan 2023 with no major issues. I suggest you do a clean install, see FAQ 11, and flash this 20 ROM BY ITSELF (no gapps, magisk, etc) and see if you like it.
Q3. What if my app, xyz, doesn't work?
A3. If your app doesn't work, then go back to your old rom.
Q4. Your rom is laggy and buggy.
A4. If you find the above, then go back to your old rom. There's only so much software can do on a 2015 budget level tablet. Remember a budget tablet will have the slower SoC/CPU and less DRAM than a top of the line model. Your tablet will also run slower when you use gapps. You can run a lot of software without using gapps. Research fdroid, newpipe, Aurora store etc.
Q5. What TWRP should I use?
A5. You MUST use TWRP 3.5.2_9. Get it from
https://sourceforge.net/projects/retiredtab/files/SM-T560NU/TWRP/
Q6. Why should I use this rom?
A6. If you don't like this rom, then don't use it.
Q7. Will you offer monthly updates with security patches?
A7. I will try to offer monthly security patches, but that all depends on if I continue to have high speed Internet in the future.
Q8. Can you help me? I'm a newbie. Can you provide step by step instructions?
A8. I don't have the time to help newbies, so please do your own research. There are lots of tutorials, videos, etc on how to flash roms. Newbie questions must be posted in the Questions and Answers forum, not here.
Q9. Can I report a bug with respect to the rom?
A9. Yes, but you need to supply the following information. If you don't, I won't look at it.
You must provide an adb logcat of the problem and tell me how to reproduce it. Note I will not be downloading any apps that require money or an userid/password. For example, if you have problems with Netflix, I cannot help you since I don't have a paid subscription. If you use some app that requires an userid/password, I cannot help you as I'm not willing to create another userid/password even if it's free.
To get a logcat, open up a terminal window.
Code:
# clear the logcat first
adb logcat -c
# start logcat trace
adb logcat > problem.txt
# reproduce problem
# wait until problem has occured, then stop trace by hitting ctrl-c
# attach the problem.txt ZIPPED as text files don't seem to get attached properly
Q10. Do I need to erase everything and format my data?
A10. Yes, you MUST erase all the partitions (system, data, dalvik/art cache, cache) using TWRP and MUST format your data before installing 19.1 when you are coming from stock or an earlier version of LineageOS or from another custom rom. If you get stuck at the boot animation for more than 5 minutes, it's likely because you didn't follow the instructions I just wrote. Dirty flashes from stock, other custom roms or older LineageOS versions are not supported and not likely to work.
Q11. What gapps should I use?
A11. I don't use gapps anymore. I use Aurora Store. As of Nov 6, 2021, I no longer make recommendations on which gapps to use as your mileage may vary.
Let me by crystal clear. YOU NEED TO DO YOUR OWN HOMEWORK selecting between the various gapps offered. There are 5: opengapps, nikgapps, mindthegapps, flamegapps and bitgapps. Each one will have it's own installation instructions. The only recommendation I will offer to use the SMALLEST version of gapps.
Don't be surprised that whatever gapps you use might have problems like "Just a sec", voice not working, updating google play store please wait, etc. These are NOT problems of the OS as the OS will run fine without gapps. These are gapps problems and you must ask in the gapps forum why it doesn't work.
Q12. I'm having problems with gapps, can you answer why it's not working?
A12. I WILL NOT answer any questions regarding gapps. This thread is about the rom, not gapps. Android does not depend on gapps in order to work.
Q13. Why isn't my post answered or ignored?
A13. Questions already answered in the FAQ will be completely ignored. Again, I do not use Windows OS or gapps.
Q14. What speed up/optimization tips do you suggest?
A14.
1. Turn off animations. Go into developer settings, scroll down to the drawing section, and set window, transition and animator scale all to "off".
2. If you don't have a google account, don't install gapps. Use Aurora Store to get your apps as you can get all the same apps from the play store using an anonymous login.
3. Dont' run more than 2 apps at the same time. You can probably listen to music in the background and use a web browser at the same time, but don't expect great performance from a 2015 entry level tablet.
4. Use a web browser like Brave that has built in adblock and privacy features.
5. Use newpipe to watch your streaming content. It has built in adblock so you don't have to watch forced ads.
6. Look for apps that are open source, ad free and lightweight.
7. Remove all unused quick setting "bubbles" from the quick pull down menu. I only need and have 6.
Q15. Does this rom support Magisk for root?
A15. I don't use Magisk myself so I don't know and Magisk is always being updated to fool Google's certification process. Others have reported Magisk as working, but I won't answer any questions regarding it.
Q16. Will this rom ever become official?
A16. Starting with 19.1, legacy devices like ours will NEVER be official due to lack of ebpf support. See https://lineageos.org/Changelog-26/
Also, I don't want the responsibilities that come with being an official maintainer.
Q17. What is the difference between this rom and others?
A17. This rom tries to be pure LineageOS with little to no modifications.
Q18. Will there be any major 20 code modifications in the future?
A18. I don't anticipate any major modifications. There may be some small bug fixes and minor code cleanup, but all the hard work in getting the rom up and running and fixing all the major bugs have been done completed. This doesn't mean the code is perfect or well organized, but I won't be doing any major changes now that 20 is working.
Q19. Why did you fork the device and vendor trees for 20?
A19. The msm8916 repos seem geared towards phones and sometimes do not work or cause boot animation loops for tablets so I decided to fork their repos. In other words, what's deemed as msm8916-common code isn't common to all devices.
In addition, since I'm building SM-T350, SM-T357W, SM-T550, SM-P550 and SM-T560NU (all use the same msm8916 code), it seems easier to maintain all of them if I can control my own code repos and not worry if my changes affects the phones or not.
I have completely decommonized and rearranged the 20 msm8916-common tree so it's easier for me to maintain and build.
Q20. Can you build a variant of this device? For example, a LTE or S-pen version.
A20. If I don't physically have the device, I cannot and will not build it unless I can boot and test it myself. Even then, there's no guarantee that I can get those variant features working.
Q21. Can I load this rom on a variant devivce like LTE or S-pen version?
A21. The rom is built for the device explicitly listed. If you are an advanced user and understand TWRP, adb, odin, heimdall, you can try loading it on a LTE or S-pen variant by modifying the updater-script, but it may cause a bricked device, bootloops or non functionality of LTE/S-pen. You have been informed and warned!
Q22. I don't like the taskbar, how do I turn it off?
A22. Choose settings, type task into the search bar. Choose enable taskbar and disable taskbar. This will leave the on screen nav bar. If you want to disable that, go to settings, system, gestures, system navigation, gesture navigation.
Q23. Will this run on the SM-T560 or SM-T561?
A23. No, the SM-T560 and SM-T561 use a different CPU/SoC. The SM-T560NU rom will NOT work on SM T560/SM-T561. I CANNOT and WILL NOT build SM-T560 and SM-T561.
Q24. Okay, I understand the consequences and that this is ALPHA rom and willing to take the risks outlined, now where can I find the rom?
A24. You can download it from https://sourceforge.net/projects/retiredtab/files/SM-T560NU/20/
Release notes
NOTE: All builds that I upload have been personally tested on my device to boot and function as described in post #1. Having said that, there's still a chance it won't work on your device due to human error, your configuration, your apps, etc. If it won't boot, always start with a complete wipe of everything and format your data in TWRP. This is known has a clean install. Backup your data before a clean install.
