[ROM][7.1.2]AICP 12.1[SGP771] - Xperia Z4 Tablet Android Development

Hi. This is my third ROM I've built.
It's stable as LOS 14.1
Tested:
Camera;
USB-OTG;
NFC;
Filetransfer to PC;
FMRadio;
etc.
Bugs:
- The same as LOS14;
- some big games doesnt download from google play(war robots downloads, callofduty doesn't (I've checked that game in los14.1, it also doesnt downloads);
- NFC-HCE(in LOS14.1 that doesnt work either);
- something I haven't found.
How to install:
1) use TWRP 3.5.0.
2) wipe all except internal storage
3) Flash the gapps , magisk.
4) You may also need to reformat sdcard.
5) If gaaps taking too much time for checking for updates, just reboot the tablet.
Change log:
20210311- initial build.
Last builds (mirror) are here.
I'm also very grateful to sabar_op for guiding me to build me ROMs in the right way.
I need you to test my ROM guys, I also can build for karin_windy too. But I dont have karin windy, If no one wants me to build AICP for karin-windy. I may not build it ang go to the next rom for karin.

Well. When I was getting to stock with flashtool I catched the error "bundle mismatch". Tried different versions of flashtool but was getting the same result. Then I used emma and then flashtool. Got to last stock. And guess what. Then I flashed again los and aicp. Only then call of duty downloaded and installed successfully.
So the problem most likely was with some partitions of the tablet or gapps or twrp often restore. If you catch the problem with game downloading just pass my way.

FAQ
F2FS
This Rom supports f2fs since the latest build. Don't ask me, what it is. Just google it.
Instructions for f2fs:
Download the modified twrp recovery for f2fs based from here and flash it
Save your data, your whole internal storage will be formatted soon.
Put the latest rom build and gapps on your EXTERNAL sdcard
Format data and cache to f2fs using twrp recovery
Flash the rom and gapps
DO NOT FLASH A KERNEL, WHICH DOES NOT SUPPORT F2FS
If you want to revert back to the usual ext4 partitions, format data and cache with twrp recovery to ext4.
Reporting Bugs
You are allowed to report bugs only in this thread.
Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. The following is a useful format to follow.

Use SuperSU 2.66
He gave bad for me!
Once you take more than two hours of installation, did not recognize my SIM cards and has also stopped for all google applications. The most common was Google Play Services stoped ... Very sad !!!

ok today I will do it this way... Thank you!
Hello guys...
I tried in several ways:
- As the Kboing;
- As the hardik190;
- I also tried a simple upgrade without the Data Wipe only with Wipe System / Cache;
- I tried like doing a clean installation;
- I tried installing the CM12.1 package with Gapps and later with the CM13 Zip only.
The results were always negative:
- Problems related to Google services;
- Problems with the recognition of SIM cards;
- And the last time with the Infinity Loop.
Really appreciate the help and commitment of friends in trying to help, but unfortunately I will keep me in CM12.1 until later builds.
Congratulations to Kiborg throughout dedication to upgrade a device so little known and with few partners to share experiences.
That's it folks!
@_Iron GApps need to be installed prior to the first ROM, put SuperSU if you need a version 2.66

@Kiborg_Man thanks
bug:my phone is not able to go to deep sleep. Wifi remains on even when is witch it off. And yes all options in location>3dot menu r off (Bluetooth and wifi scanning) don't know what to do. Wake locks are caused by cyanogenmod system.
Hope u look into the problem.

Let's see if understand:
- Should I install the CM12.1, Gapps 5.1, but should not activate the SUPERSU.
- Afterward WIPE DATA, WIPE CACHE Davik, WIPE CACHE.
- Install CM13 and Gapps 6.0-leave boot
My doubt is regarding the SUPERSU, I only installed it when the ROM shows me a message box saying that will update the SuperSU #.
You must install it by recovery mode?
Thanks for the attention of everyone there

Specially to install CM12.1 is not necessary, the following points need.
Install SuperSU version only 2.66 or 2.67 through recovery.
One more question...
In this version NETFLIX is OK?
in CM12 :bad:
Hello guys..
I have installed this ROM with 6.0 stock GAPPS for 3 days.
Issues that I know so far:
- Google camera always stop working for using other than camera( video, panorama, photo sphere )
-random freezes, that I need to pull out the battery
-sometimes phone restart itself after clearing apps from the overview(recent apps switcher)
Other than that issues, this ROM run smooth.
Thank you for the work :good:
Hmm... When I flash SuperSU 2.66 it boot loops.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.
IMPORTANT INFORMATION
Root is not included by default on LineageOS 14.1. You need to install an add-on via recovery. You only need to install this once. You can download the SU add-on here
After installation go to Settings>Developer Options>Root access and set to Apps only or Apps and ADB.
LineageOS comes with LineageOS Recovery by default, if you don't like it (like me ) you can flash alternative recoveries using IsoRec. You really need 1GB /system partition. The smallest build-configuration is larger than 512mb. You can use ODIN, but you can also use Lanchon's REPIT.
If you're interested in BLN, check this thread for a complete support of this feature.
If you're interested to go to emulated-storage, check this thread.

I think ist is just a mistake and should mean "open gapps"
http://opengapps.org/
Sent from my ME173X using XDA-Developers Legacy app
In General forum? Why not in Original Android Development?
Which GApps exactly?
Just to prevent from questions like "which GApps architecture and version do I need?"
This link will show you the minimal OpenGapps variant independently of your last visits (cookies never forget you)
http://opengapps.org/?download=false&arch=arm&api=7.1&variant=pico
(so only the variant needs to be changed if you prefer bigger packages)
Edit: Check this post to see how to create a customizable config that allows you to control the OpenGApps installer, e.g. to downsize bigger GApps packages for flashing Pixel Launcher while skipping other components you don't want. Included a sample config-file there as well.
I have questions:
FM Radio?
upgrade of CM 13?
TWRP emuled storage installation and new repit procedure?
from cm-13.0-20161218-nightly to lineageOS 14.1

Only if you're coming from cm13 without losing data (i.e. your apps installed). Otherwise - wipe clean and install the recent nightly only (and gapps if you wish).
-3. Get a good cup of coffee.
-2. You must have at least 1GB partition of /system. If not, first repartition your storage (see OP) and then come back to here to proceed.
-1. Proceed to oficial download site: "https://download.lineageos.org/i9100 for the current build, https://www.androidfilehost.com/?w=files&flid=154035 for the experimental build, thanks to @ale5000 for uploading this for us.
0. Download the latest 2 following files: Nightly and Experimental (as for now lineage-14.1-20170208-experimental-i9100-signed.zip and lineage-14.1-20170208-nightly-i9100-signed.zip). Verify their md5 checksum to prevent errors, it is vital to do so.
Optional - download gapps from [url]http://opengapps.org/[/URL] for android 7.1, ARM (the nano is fine for me).
1. Boot into recovery. Install the "experimental" zip (Dirty flash! No wipes!).
1.5. You can reboot now into system, just to get a systemUI crash errors and a blank screen. Pretty useless. If you got to here then force reboot to recovery and proceed to step 2.
2. Reboot into recovery! Install the "Nightly" zip and gapps.
3. Wipe cache and boot to system.
There you go kiddo'.
Good luck! :fingers-crossed:

It is relatively very stable to me, most is working! Phone and RIL, audio, GPS, BT, and a lot more!
I believe battery has improved too. Performance is very well.
This is my only phone, I rely on this phone, and on my daily use no problems so far! And yeah this ROM rocks!:good:

People asked for a simple migrating guide from CM13 to LOS14.1, if someone isn't heading to switch to emulated I don't see a reason to send people to install an emu-recovery while they don't wish to.
It should be a decision for users.
Therefore I don't see a reason to include special addtional options besides the basics (exp+nightly+gapps). Whoever wants to expand more should simply read the OP and the links.
As for myself yes, I'm on emu now.

Hmm, because this phone is my main and only phone, I won't be able to test that soon (reverting recovery and ROM to cm13, reverting repartitioning too, then starting to trial and error).
But I believe that the safest way is to start from the moving to LOS14.1 - flashing the experimental and nightly first, as I guided. Then later flash emu-twrp recovery and proceed with rINanDO's instructions.
I'm afraid doing opposite (emu'ing first and then flash exp+nightly) might not work since Lanchon and the guys warned us that this emu-kernel might not work even with cm13 and maybe even affect it! Maybe repiting manually with Lanchon's magic REPIT would do, then migrate ROM, then change to new emu-recovery.
PLEASE:
- don't direct-link to recoveries that will brick your phone if installed too early.
- read the linked threads in the opening posts to understand the complexity of any of the changes
- if understood the consequences and you still want to do them all at once: know your limits
- if still feeling comfortable until here: go ahead *but do it in the correct order* or your phone will bootloop as all the newer test-recoveries were built with a Nougat ramdrive and thus will very very likely bootloop on your phone if installed on non-Nougat ROMs!
So my advice for your own safety: stay in your lane and read everything first.
EDIT: And by the way: please keep emulated storage discussions in the appropriate thread until it is officially tested and documented to be kind of noob-proof.

I can't install gapps, help!
Only pico gapps can be installed, if you still unable to install pico gapps
create a .txt file named gapps-config.txt with the following contents:
Code:
Exclude
GoogleTTS
and copy that file to the root of your /sdcard, after that install pico gapps.
Recommended gapps-config for opengapps nano (with faceunlock support):
Code:
Exclude
GoogleTTS

Upgrading from 14.1? Read this!
Android 8.1 is noticably bigger than previous version and directly flashing 15.1 over 14.1
is only possible when you got no gapps or pico gapps installed. If you used for example nano gapps
the correct steps of upgrading would be:
- Boot into Recovery
- Wipe system and cache
- Flash LineageOS zip
- Flash Gapps Pico
- Reboot
LineageOS + MicroG

Downloaded and flashed with the pico open gapps. So far working perfectly. Thank you very much voron00
Hm, automatic LiveDisplay doesn't seem to be working for me, I'm fairly sure it did on unofficial builds. I'll have to check back on this.

I'll perform some additional tests and get back to you. For some reason it didn't automatically turned the night mode on. Manually switching between modes work though.
Ah, great the party started already!

I did a clean flash today with the first official LOS15.1 including pico gapps and magisk 16.0 and everything went without a glitch.
The only issue I have is installing Adaway (Fdroid installed just fine): Adaway is greyed out in the Fdroid app whereas I could install it on my Nexus 6.
What is the trick to be able to install Adaway?

You can use the XDA adaway version directly: https://www.androidfilehost.com/?fid=673956719939825702
I get an FC when I try to open settings, system, buttons...
Log attached
https://drive.google.com/file/d/1FUKefen_oyVxjBQCOuS1lvGLHZ1H-G_s/view?usp=drivesdk
Edit: I do use magisk, so I totally understand when you choose to ignore this...
Edit2: just checked and it also FC's without magisk being present, just couldn't take a log as Matlog needs root and I'm not near a computer, I however didn't clean flash, I updated as suggested by OP (wipe all but internal storage & data)
Edit3: from my observations, when changing overlays in settings, display, advanced the buttons page starts to appear for a second and then crashes - I assume it's an overlay issue, as seen so many times by substratum... Even though the log complains about lineage parts right before the fatal exception but anyway I'm terrible at reading logs..

Have a problem now with Sberbank Online app - it now detects this ROM as modified or rooted (didnt install su addon) and works in restricted mode. With previous builds of 14.1 (inc. the last one) it works normally like with stock rom.
Upd: I've send them an e-mail asking to add this rom in the whitelist.
Also, now phones wi-fi can't detect my 5Ghz network for some reason. Didnt change any settings on my router since 14.1 builds.

Thank you! When using this do I get automatic updates?
The reason I ask: I could download some AdAway apk's directly from F-Droid but I wouldn't get any update notifications: https://f-droid.org/en/packages/org.adaway/

Love your work! It works perfect on my matissewifi! No known issues! Have a lot of thanks, crazydrive22!
New Builds with February Security Patch are online.
There's still no fix for the broken Camera at Millet-Devices.

HI Crazydrive22,
Just downloaded latest Feb update for MilletWifi.
This build has some major issues, same as original crROM Version.
1. When updating using dirty flash, or clean version. Using TWRP v3.4.0-4 millet version, Nandroid backup does backup, Boot partition that is Rooted with Magisk 20.4. Your Rom overwrites Boot partition. Therefore Magisk Root is removed, therefore needs to restored.
2. After flashing both crROM versions released in Jan and now Feb. Require latest version GAPPS Nano, to be reflashed again, to stop Google Play services, crashing every minute or so. Reflash Gapps fixed that , as well other random Google apps, also crashing continuously.
3. After finally getting things back to normal, on latest crROM Version, needed a couple of restarts, as Tab4 was slow to respond, to some apps to operate at normal speed, compared to Matteo's builds. I have been using for 12 months now.
4. Then found internal memory is running out of space. Had plenty of spare, before using this ROM. Needs more research to find cause. Originally did a Wipe then clean flash and reinstalled all 100 odd apps, via Google Cloud.
5. I restored previous Matteo, Jan 21 build Nandroid backup with same number apps, plenty of internal memory left.
6. Tried to install your LOS16 Dec build, to compare with Matteo version. Downloaded from both sources, listed above in Post 1. Zip file crashes each time.
Found I needed to repair it , to allow me to open it. That is why, TWRP flash failed.
I did MD5 compare, that passes each time. So I suggest you need to upload again, a recompiled LOS16 ROM.
7. I have been working with Matteo, to help solve the Millet version CAMERA issues, over the last few months. But Matteo, has run out of ideas, at the moment.
8. So I decided to try crROM build by you.
But sadly still got issues with saving photos, but video front and rear camera works.
Panorama works saving photos. But photo saving crashes Camera app, with same unknown message, same as Matteo's ROM.
SO I suggest you have a look at the issues mentioned, and keep trying to resolve the camera issues with Matteo.
Great work so far, thanks for your effort to add another ROM for these OLD Devices.
Hope that helps you with some feedback, I have found some minor issues, that I had managed to fix easily.
Cheers

Thanks for your Feedback. Unfortunately I don't own a Millet Device and can't reproduce this errors atm. I'm looking to buy one in the next time.
Could you please dl and test my latest LOS16 Build i uploaded today? This should be exactly the same as Matteos, cause i'm using his Device Tree.

Hi crazydrive22,
I will try LOS16 Build for you.
Another issue with crROM.
Adding extra Icons on Home screen. Work OK. But I save them to lawn chair option on internal memory and extSD card for backup. Backups produced OK on both locations. But Restore only restored original icons on 3 screens, but not newly added icons on any of the 3 screens including Home screen. Tried a few times, created extra backup files on internal and ext SD card. Available in Restore list. Copied files created between both. File size increases as I add more icons to Home or other screens. Just not showing up when I restore any created file.
I want to use this option, by installing the crdroid home 9 app. On Matteo ROMs, so I can Restore icons, on all screens, after a re-flash of any ROM. Would really be useful, save heaps of time, as I have some 100 odd apps.
Any ideas.
Cheers BeeJ1109
Hi Crazydrive22,
Sorry Tried LOS16 Latest version. Boot loops everytime.
Let it go until TWRP reboots as Recovery.
Re flashed a couple times, wiped cache, dalvik , system a few times, no change, still boot looping.
Cheers. BeeJ1109
Working perfect! No bugs!
When update to Android 10.0?
My Tablet: SM-T530
Before Andrdoid 5.0.2 and now Android 9.0!
Hi,
Flash does not work with twrp 3.0.0, but this is the latest official twrp.
Can you suggest a TWRP version for this ROM?
Hi All,
TWRP 3.4.0-4 by Matteo works. My device is Milletwifi.
Reflashed again after doing tests on Stock ROM for Matteo, did Wipe Cache, Dalvik & System, then reflashed this latest version.
Booted OK This Time. Instability with Google Play Service, So reflashed Nano Gapps. Fixed instability. But WiFi had issues, would not accept Password on several of my WiFi connections on both 2.4 or 5Ghz channels being Routers, Repeater, or Extenders.
Still using Stock EFS & Modem, same partitions, have not been overwritten. WiFi D.L was > 54Mbps, U.L > 18Mbps. Works great on Stock ROM.
So this ROM LOS16 Feb Build has issues. Camera does not work, same as Matteo's LOS 16. In fact this ROM appears to be identical to Matteo's LOS16. Apart from being compiled, by Crazydrive22. Therefore different title in About. Not sure what Crazydrive22 is trying to achieve here, apart from proving the Compile works, using the same repository sources as Matteo.
So I have restored back to Matteo ROM Feb Build. WiFi is back to same as before.
So I attached files.
Cheers BJ

Sorry Guys, i was very busy the last time.
Matteo decided to go to LOS17 and LOS18, so I will build LOS16 for the future.
That's why we are building side by side, to check if everything is working well.
And as you've seen, it was a good idea.
With the next build (around 5th of March) everything should work on Millet, except the Camera.
god to know.

If you switch the Version always clean flash with TWRP.
Updates as long as it is BETA via TWRP.
Maybe i'll go to OTA later, but there's no ETA so far.

[UNOFFICIAL][ROM]ALPHA LineageOS 19.1 for Galaxy Tab A [SM-T550] May 6, 2023

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
8. camera
What doesn't work
1. 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.
2. 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
3. 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 @breversa , @XDA_username00 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_gt510wifi/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/android_vendor_samsung_gt510wifi/tree/lineage-19.1
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://dl.twrp.me/gt510wifi/
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. 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-T550/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. 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?
A26. You can download it from https://sourceforge.net/projects/retiredtab/files/SM-T550/19.1/
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.
19.1 has been my daily driver since March 2022.

Reserved.
Wanted to report no issues with this recent version via in-place upgrade from last month's v19.1 alpha test build.
For anyone still running v17 or v18 wondering if it's worth upgrading, it depends on your use case.
Here's mine if it helps:
I use this SM-T550 tablet on a semi-regular basis for web browsing, reading e-books, and watching video content.
Using v3.6.2_90 TRWP with a microSD card and some Bluetooth headphones.
No gapps, Bromite Chromium browser, NewPipe, and all other apps downloaded via anonymous session using Aurora Store (which also works great with tracking updates).
Apps: Bitwarden (still slow, but faster than when on v18), Netguard, Netflix (no DRM issues), Nova Launcher, Plex, United Airlines app (need the Bromite browser installed for DRM content to play), and Amazon Kindle.
Works great.

can you give more info please. is good for the daily use? thanks
I used now more than 4 weeks and all what I have tested works perfect.
It is my daily driver.
Bluetooth works , WiFi connection is much stable if you have an worse signal.
Battery consumption I much better than Los 18.1
I have the smt550. Do you have a guide to root it and install this rom? Where can i find it? Thanks

Everything seems to work (except RIL as mine is an LTE device). Just bear in mind that SELinux is disabled, so you might not want to use the tablet to store sensitive data.

A general guide to install a custom OS for a Samsung device can be found on the LineageOS website. Here's an example for a different Samsung device https://wiki.lineageos.org/devices/beyond1lte/install
The main differences are you'll need to refer to the original post Q5 to obtain a custom recovery (TWRP) and Q26 to obtain the LineageOS build.

Just sent you PM with the steps I used to get it on mine.
retiredtab said:
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
8. camera
What doesn't work
1. 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.
2. 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
3. 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 @breversa , @XDA_username00 for willing to test pre ALPHA builds and leaving feedback.

Hi, Installed 19.1 recovery, did factory reset, formatted system and installed 19.1 version. No error messages. Unfortunately it keeps booting into recovery only. What did I do wrong?

At first you have to tell us from which ROM or OS ( Stock ) you are comming.
Which Recovery you have installed ? TWRP or Lineage Recovery.
Have flashed only LOS 19.1 or LOS + Gapps ( which Version ) or have you flashed LOS + Gapps and Magisk ?
Try it again , factory reset and wipe cache , Data ( int. Sdcard ) System.
Flash Los and reboot system.
Is this OK . next step factory reset, flash Los and Gapps
Reboot system and so on.

Is there a reason for going with the LOS recovery image instead of TWRP? TWRP has worked great for me since v17 and haven't had a need for recovery with the SD Card, but then you might have a particular use case.
Remember you'll need to wipe the dalvik/data/internal storage/cache/system partitions first, then format data before installing the OS.
Hope any of that helps.

What was the reason that you have flashed the Lineage Recovery, since TWRP worked before ?

Idk, thought that it would be necessary to flash the 19.1 rom... But I also got back to 18.1 version since 19.1 is more laggy and has ugly QS tiles.
