LineageOS 14.1 for Sony Xperia Huashan
Xperia SP (Huashan) : http://forum.xda-developers.com/-/-/-t3529514​
General Questions & Answers
Is root access included into LineageOS ?
No longer included by default to improve user security.
An addon is shared to add SuperUser features : https://download.lineageos.org/extras.
It will survive to updates the same way GApps do.
Go into Settings, About Phone. Tap "Build number" 7 times.
Go back, open Developer options. Change "Root access" option.
Do not use SuperSU unless you are sure, creates booting issues.
Read more about it : Here.​
Is the ROM suited for daily usage ? Google Apps compatible too ?
Yes but work in progress. OpenGApps recommended.​
Can I flash LineageOS on official and development builds, or even on CM without wipes ?
Migrations from unofficial to official, and from CM builds, are allowed with an experimental migration.
Read more about it here : http://lineageos.org/Update-and-Build-Prep/
Always remember to do backups before doing such changes.​
Is the device encryption supported ?
State unknown. If you're coming from an older ROM
please read the details here : a07afb9660a86f702066003b8e81ab63789d1660​
When USB connected to a computer, I can't access the storage ?
The phone is in charge-only mode by default on Nougat,
due to a stronger security logic regarding unauthorised data access.
Swipe down the notifications and change the USB mode.​
I can't access the ROM's recovery with Volume-
You can either flash the boot.img from the newer Releases with "fastboot flash boot boot.img" or FlashTool,
or follow the instructions of the TWRP Recovery installation to update from TWRP.​
Against advice, I upgraded without GApps and now it crashes. Any way without factory reset ?
Yes there is, but nothing assures you'll manage to do it fully & preserve all your data...
Once booted, keep saying Ok to all "Unfortunately, ... has stopped",
pull-down the notifications panel, press the Settings icon,
go in Apps, menu, Show System, scroll to Setup Wizard (green Android logo),
Permissions, and activate Contacts + Telephone.
Later, some Play Store apps may need reinstalling.
If not working, then I advise a clean factory-reset reinstallation...​
The AOSP Keyboard does not support swipe gestures ?
Unfortunately the sources for swipe gestures are not available
and Google still requires their prebuilt library to be there for AOSP Keyboard.
Download the following libjni_latinimegoogle.so API 23 from OpenGApps
and push it to /system/lib/libjni_latinimegoogle.so using root access,
or use my one-time install zips : https://mega.nz/#F!ThEAkCRa!byhSwuoTbf6lnC1JxgKrig.​

Thank you so much @AdrianDC for all the effort you make to keep SP in top notch condition <3
Oh and Happy New Year Bro

thnx adrian for ur efforts wish u a happy new year ^^

@Adrian DC
Thanks for your excellent work and support. Happy New Year.
Use packages for ARM, Android 7.x, Micro or Pico

Is there any reason why you recommend the micro/pico packages? I am thinking to flash the stock package and I see that replaces a lot of stock/AOSP apps. Will that cause any problems with the ROM? Thanks in advance.

System partition is not big enough on older devices to support ROM and full gapps packages.
Pointless anyways as most apps can be added from the Play Store.

Hi Adrian,
happy new year! I see you can't wait until new year to release the LineageOS for our Xperia SP, that's crazy Thank you, again!
One thing I could find in your first post: In future the root access will be removed from LineageOS? Yes, I know you write
information will be given later, but I'm nosy.. Any reason for this change by you or LineageOS?

thank you. Happy new year

Yes, same for me here regarding the CM/Lineage file manager. If I use for example the Totalcommander it's no problem to use the SD-card.

but since the app is already included in the rom, and I don't want another app taking some precious storage. Still can manage to access the sd card's file through the settings menu. But better if the sd card's access is fixed at the app itself.

I have exact the same intention, but I can't fix it by myself. So I have to wait if most likely Adrian have time to fix it. My expectation is, due to the shift from CM to LineageOS he is busy with more important tasks. So my idea is just a temporary solution, until the standard file manager app is fixed.

just a workaround not a solution, you can access SD card's files from settings then Storage and then press the SD card name/icon and try to avoid pressing the eject button ofc

Thanks a Lot for this Rom @Adrian DC
I'm having issue with offline charging.
when i unplug the charger, it shows the battery percentage and hang in there.
pressing power on/off key do nothing.
have to press emergency power off button or,
press and hold volumeUP and Power on/off button until phone vibrates.
Is there permanent fix for this?

I'm pretty sure that in the builds a months before the end of CM13, there was the old charging animation, the colored one. Back then, everything worked find.
When I flashed the last snapshot of CM13, I got the black and white charging animation and since then, the bug has occured.
I hope this makes it easier to find out which commit caused this regression.

[ROM][Pie] Unofficial LineageOS 16.0

This is an unofficial build of LineageOS 16.0 for the Motorola razr I, (XT890/SMI).
Lots of thanks to Hazou. This rom is based on his los-14 rom and I got help from him with los-16.
This rom has full hardware support and should run stable. It has been tested by me in daily use. I'm using the rom without google apps, but with microg. Installing google apps requires some apps to move to data partition because of limited system size. See install description for more info.
Special Features
-All features of Hazous 14.1 rom
-MicroG signature spoofing patch is included.
-Adaptive icons can be disabled in homescreen settings.
I can include more features if requested
Known Bugs
-The camera preview image sometimes shakes at random
Download
https://mega.nz/#F!5fBWlIAQ!Jlq9Bj789iJ0iIIptK00tg
Update
If you already run an earlier version of this rom, just boot to twrp and install the latest flashable zip file
Install
1. Backup everything you don't want to loose.
2. Download and install TWRP 3.2.3 (download in attachments. Can be flashed with fastboot or with another recovery)
3. If you come from another rom do a full wipe with twrp
4. Download and install the rom flashable zip (download from mega.nz link is in section download)
5. If you want to install opengapps or need system partition space for other things. Install the move_to_data.zip file from the attachments. This will move the Webview and the LatinIME app to data partition.
6. Choose one of the following options:
-either install google apps (download form https://opengapps.org/. Choose x86 9.0 nano or pico)
-or install MicroG (can be installed with the unofficial installer https://forum.xda-developers.com/android/development/microg-unofficial-installer-t3432360) this is lighter in ram and cpu usage but you will get problems with google chrome and other apps
7. If you want root access install the addonsu-16.0-x86.zip (download in the attachments)
8. Reboot the phone. First reboot will take some time

DATA Encryption
If you want to enable data encryption this would break the pds partition backup. To prevent this, the cache partition can be used as backup location:
-edit /system/bin/pdsbackup.sh
-change PDS_FILE=/data/misc/pds/pdsdata.img to PDS_FILE=/cache/misc/pds/pdsdata.img
-resize data partition in TWRP:
Code:
umount /data
umount /sdcard
e2fsck -f /dev/block/mmcblk0p17
resize2fs /dev/block/mmcblk0p17 1367079
-reboot the phone

This if I did not expect it, I'll try to see how it goes. Thank you.

Download links and install description are up now. Download from mega.nz because xda download section is broken at the moment. I'm waiting for your test reports

It's really great works, thank you!!
I quickly tried and found several points.
- USB connection with PC
All USB connection option including File Transfer, USB tethering, PTP are grayed out.
Disabling/Enabling android debug in setting didn't work.
- Wifi with storage encryption
When you enable storage encryption, WiFi always become disabled, not be able to enable.
Just FYI, it required deleting /system/bin/pdsbackup.sh AND reducing partition size of 'data' (/dev/block/mmcblk0p17).
- SElinux
Although it is designated as permissive in device.mk, it's actually worked as "disabled".
I'm not sure it's related or not, however, when building "user build", it's failed with "ERROR: permissive domains not allowed in user builds".
I know "user build" is not officially supported in Lineage release, however, it's really helpful if we can do it for AFW usage.
Previously I could use Lineage 14.1 smi build for AFW and safetynet app with user build.
BTW, performance is really great, seems to be almost same as Lineage 11.

I also noticed that. Will see how this can be fixed. It is just a problem with the option dialog. Usb connection works fine. As a workaround you can set a default USB configuration in developer options

I think lineage trust doesn't differentiate between permissive and disabled. Selinux support is planned for future releases

Thank you for quick check.
Regarding USB connection, I also confirmed that Ubuntu can recognize as external storage with above option, besides Windows still does not recognize. Maybe depending on my environment.
Also I noticed that Chrome, Chrome Beta and Chrome Canary (therefore another Chrome based apps such as Maps Go) always crash. This is also maybe my environment only, though. BTW, I could install MicroG, besides couldn't install OpenGapps 9.0 pico due to partition size limit.
Additionally, I couldn't find any LED settings, currently LED is always off during charge or any notification.

Notification Led should work. Can be configured under settings->apps and notifications->notifications->notification light. I don't know what happened with the battery light. It will hopefully come back if I upgrade the driver to hidl.
Google Chrome is a known problem with MicroG. It requires official gapps. I will check if some of the unprivileged lineage apps can be moved to data partition to make place for google apps

Newbie question
Hi all, I know someone who's selling her old RAZR i XT890 and I'm interested (for experimental reasons but also the oddity that it's Intel powered). I've never owned a RAZR i so I've got some questions:
-The phone is from 2012 so quite old and has 1GB RAM, does it work well with this Lineage 16? Because usually newer software would perform bad on older SoC (I used to have iOS 7 on iPhone 4 back in the day and it was painfully slow compared to 6).
-On Lineage 16, can it run any Android app as a standard new Android Pie phone? I ask because this is an Intel x86 CPU, so can it still run Android apps as normal or are most of them only designed for ARM and therefore unusable?
If I get the good news, I may buy the phone and try this Lineage OS custom ROM.

Regarding LED, maybe it became working after modifying some option of notification light. Battery connection light is still always off.
Regarding opengapps, I moved webview and LatinIME from app directory to external SD in TWRP, then installed as normal app after system boot. Webview worked fine besides LatinIME always crash. I'm using different IME, so it's no problem. With this environment, opengapps nano can be installed, then Chrome, Maps and other google apps worked.

That's good. Than we can make a flashable zip to automatically move and symlink them to data partition.
I will provide a new build till end of the week with improved usb and notification LED implementation. I already got it working in my local setup

Newer android versions have been designed while keeping low ram devices in mind. Ram hungry special features like the picture in picture mode are excluded from builds for older device. So the situation is much better then on iOS. But a newer phone would run better thought.
Most android apps are available for x86. But some are still arm only and get automatically emulated. The intel houdini emulator integrates these apps natively into the system but they are a bit slower then x86 apps. These are for example Skype and a few unity based games

Thanks for the response. So I should be alright with it then, hopefully. I just hope it won't lag on that old SoC. I'd love if you could upload a quick video of it in action.

Yes, system partition size is limited on this phone. To install GApps some files need to be moved to data partition.

Alright, thanks. I bought my friend's RAZR i and I am planning to use it as a daily driver with this ROM (I'm a light user anyway), I can't thank you enough for making this LineageOS for such an old device. I wonder if such a recent Lineage has been developed for the 2011 Atrix, haven't seen one.
I have questions though, firstly I've never used a custom ROM before, can I simply follow the instructions on this thread to get it working, or is there anything that has to be done beforehand like rooting? Secondly, are any other OSs successfully booting on this x86 phone, as I can't find it on XDA? (it surprisingly hasn't gotten much attention as a hackable device like HTC HD2 or Nokia N900 got).

I'm not sure if I misunderstood but when you said "it required deleting....." and "reducing partition size of data", did you mean you can get WiFi to work if you do those things? I'm no expert at these but I can atleast apply the "fix" (if it really is) given that you guide me, if it's okay with you. Thanks!

Make sure you really deleted this part in manifest.xml in vendor partition. For my test result, it solved the doze issue.
Or wait for next build.

I did remove bluetooth version 2.0 codes. as I said before it didn't change anything.
I got to say that rom was really smooth and stable for a beta build.
I will wait next build. Thanks anyway.

hehe, LOS 18.1 for this device, good news
@Sjll: Is it possible the include the signature spoofing patch (to be able to use microG) in your new build ?
That would be great since there is no opportunity to patch this from 'outside' afaik ...
Thanks in advance

I have checked proximity sensor with Dev Check App. My proximity sensor works fine and rest of sensors too.
The problem is when I tap on person name in contacts list , calling screen doesnt pop up but you can hear dial sound.
Except the above problem it seems everything works fine for now.

Anything to care of if using the single model (F331) ?

rom says "Sony Xperia XZ Dual!"....be caution.
This mean, rom will change your phone model number from F8331 to F8332!
just in case , during first clean installation get your twrp backup for your f8331 rom.
if you want to get back old stock rom f8331, you will need your backup to turn your phone model back from f8332 to f8331.

alright, thanks mate, that should be no prob at all

lineage-18.1-20210419-UNOFFICIAL-kagura.zip Test Review​Edit: Some are minor
** Experiencing reboot when taking photos using Camera for a while. (especially front camera, 15 seconds or sometimes while taking 2-4 photo) EDIT: I finally get the error after using 3rd party camera it shows me this error. (Camera ID 0 at the back and ID 1 at the front) you can recreate the error using the attached 3rd party apk

** Frequently reboot when auto rotation is on while the phone is on landscape mode.​** Random reboot when using fingerprint unlock. (encountered 4th time now)​* After receiving notification screen won't turn on. (experience once)
* Double tap to sleep/wake don't work
** When turning on the phone from a long sleep, the touchscreen won't work or frozen, you need to press the power button for the phone to sleep then press again to turn it on for the screen to work. (I thought at first it's on the gestures that are not working but after several times of occurrence I notice that it's not responding to any touch, you have to turn off the screen and turn it on again for the touch to function)
* Sometimes you cant pick USB Preferences when connecting to a computer, but restarting the phone can fix the problem.
** Heating issue.​---------------------------
USB OTG: Ok - works fine.
USB Tethering: Ok - works fine.
The data signal is better than stock. (in my experience)
---------------------------
rooting using Magisk makes me boot-loop.
still testing...​

Hi @Sjll will this rom work for the Xperia XZs?

in the following conditions, the device will reboot
sometimes in camera, but the built-in gcam go is working fine for me.
the flashlight is turned on
sometimes while unlocking the device through the fingerprint sensor
IDK why but while launching the "mi home" app
and there are some issues in the following
sometimes especially after a long time of not using the device, the screen will freeze after it was turned on. it's the same whether it has the fingerprint unlock activated or not. after it was unlocked through the fingerprint and go into the home screen, it's not responding to any gestures. it happens more frequently than lineage os 16.
for some reason, it can't pair with my wireless headphone, and it says "system UI not responding". and I press "stop" and the screen goes black and it reboots.
the speaker and microphone are not functioning well during the "phone call" on the "local" hardware. I also encountered this issue when at lineage os 16. when I was in lineage os 16, my solution is connected to a wireless headphone, and it solved the problem. but since I can't connect to a wireless headphone currently, I can't figure out any solution and I can't make any phone calls. to be specific, when I am calling others, I can hear their sound, but they can't hear my sound. if I turn on the speaker mode, I will hear my own sound from my speaker with lots of noise.
and I am only a junior high student if any info I've given is wrong, I apologize.

[UNOFFICIAL][ROM]BETA LineageOS 18.1 for SM-T813 - June 9, 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.
This is ONLY for the T813. I do not have and will NOT build T713, T719 and T819. See post #2, FAQ 20. Any questions asking to build these will be ignored.
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. selinux enforcing
9. deep sleep
10 DRM level 3 (SD definition)
Known issues/What doesn't work/what's not tested
NOTE: If any following features are important to you, don't use this rom as I will not be fixing them because I
i. don't use/need that feature
ii. already tried fixing it and couldn't succeed and won't spend anymore time on it.
1. Stock camera doesn't work at all (reason i and ii). Opencamera version 1.51.1 works for taking pictures and videos BUT with a 10 to 15 second delay when switching between functions.
I have not tested any video conferencing apps so they may or may not work. If they don't work, revert back to old rom as I will not be spending anytime trying to fix/troubleshoot.
2. fingerprint (reason i). I never use it and I see it doesn't even load correctly in the logs.
3. ARM64 gapps (reason i). 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 ARM64 gapps.
There are various gapps projects (at least 5 in 2023). 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/days 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, I have opened a new thread at
https://forum.xda-developers.com/t/...o-use-discussion-for-18-1-rom-sm-t813.4540423
so you may discuss gapps. I will NOT be participating in that thread as I do NOT use gapps.
4. disk encryption (reason i). Never tested.
5. If you restart the device with the purpose to reboot it and the usb cable is plugged in, the device will not reboot and stay in charging mode. Simply unplug the usb cable, wait 15 seconds and restart the device.
Source code
All the source code including the kernel is provided in post #2 FAQ1.
Thanks
1. LineageOS team for source code.
The rest in alphabetical order.
2. @Deltadroid for updating the msm8976 kernel for branches 14.1 and 16.0 with bug and security fixes. I'm using his 16.0 branch.
3. @lifehackerhansol for suggesting that I kang the pm-* proprietary blobs from another rom and making suggestions for possible fixes to the camera.
4. Team Infusion Developers github.

FAQ - I spent hundreds of hours building this rom. 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/syphyr/android_kernel_samsung_msm8976/tree/lineage-16.0
The device tree files are at
https://github.com/retiredtab/android_device_samsung_msm8976-common
https://github.com/retiredtab/android_device_samsung_gts210vewifi
The vendor tree files are at
https://github.com/retiredtab/proprietary_vendor_samsung_msm8976
The manifest.xml (or roomservice.xml) and build instructions for 18.1 are at
https://github.com/retiredtab/LineageOS-build-manifests/tree/main/18.1
Q2. Is this BETA 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 Oct 2022 with no major issues. I suggest you do a clean install, see FAQ 11, and flash this 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. 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 3.6.2_9-0. Do not use any other version for these reasons.
https://forum.xda-developers.com/t/...or-sm-t810-jan-11-2023.4430349/#post-86745013
https://dl.twrp.me/gts210vewifi/
I will not answer questions if you don't use this exact TWRP version.
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. In addition, I don't run Windows OS at all.
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 build 19.1 and higher for this device?
A10. Any questions on higher Android versions will be completely ignored. I do this in my free/spare time and will not be subject to any ETAs or demands. If you want a higher version, the source code is freely available as per FAQ #1 and you can build it yourself.
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 18.1 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.
You MUST FORMAT DATA in TWRP so backup your files first to some external storage (external microsd or PC).
NOTE: After you do the above, first boot (without gapps, magisk, etc) will take about 90 seconds. It may pop with a message saying "System UI isn't responding". Hit close app and then reboot the tablet again.
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 ARM64 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".
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 in the thread below.
https://forum.xda-developers.com/t/...-use-discussion-for-18-1-rom-sm-t813.4540423/
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.
Q15. What speed up/optimization tips do you suggest?
A15.
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. Use a web browser like Brave that has built in adblock and privacy features.
4. Use newpipe to watch your streaming content. It has built in adblock so you don't have to watch forced ads.
5. Look for apps that are open source, ad free and lightweight.
Q16. Does this rom support Magisk for root?
A16. I don't use Magisk. Magisk is always being updated to fool Google's certification process which may or may not work.
Q17. Will this rom ever become official?
A17. Never. I don't want the responsibilities that come with being an official maintainer.
Q18. What is the difference between this rom and others?
A18. This rom tries to be pure LineageOS with little to no modifications.
Q19. Will there be any major 18.1 code modifications in the future?
A19. 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 completed. This doesn't mean the code is perfect or well organized, but I won't be doing any major changes now that 18.1 is working.
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. To be clear, I will NOT build T713, T719 and T819.
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. Does this rom support OTA updates?
A22. No and I have no plans to add that functionality.
Q23. Okay, I understand the consequences and that this is BETA rom and willing to take the risks outlined, now where can I find the rom?
A23. You can download it from
https://sourceforge.net/projects/retiredtab/files/SM-T813/18.1/

Release Notes
I have personally tested all the functionality as to what works as per post #1 before uploading the build. 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. This is known has a clean install. Backup your data before a clean install.

3. If you are upgrading from a custom rom, stock or any older versions of LineageOS (like 14.1, 16.0 or 17.1) YOU MUST wipe dalvik/cache, cache, system, data and internal storage partitions in TWRP and FORMAT DATA in TWRP. You cannot dirty flash at all. Backup your data first.

Reserved #4

I have personally tested all the functionality as to what works as per post #1 before uploading the build. 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. This is known has a clean install. Backup your data before a clean install.
18.1 has been my daily driver since Oct 2022.

Thanks for all your efforts. I never thought anything above Android 10 would see the light of days on the T813 model, since it was highly neglected here in my opinion. I will definitly try it out

THANK YOU "RETIREDTAB" this is awesome!
I will try it out on my T813 and report back here if there are any problems, Thanks a lot for this rom!!!

@retiredtab, many, many thanks for this rom. Have done a full clean install, the backup of the previous 17.1 took longer. So far everything I need to use is working perfectly. I mainly read the news, pick up emails and buy too much stuff from amazon.
went with the opengapps pico set, and all my google stuff is working, and it restored my apps from the previous backup. Did have some odd issues giving permissions to to the various google apps but once that was sorted it ran.
keep up the good work, and will keep testing

Further update after a weekend of use, the screen off battery drain seems to be minimal(may be Greenify helping) but appears to be better than I had on the previous 17.1 rom. No other issues found as yet.

will the camera issue be adressed or it will stay like that?

I'd say its unlikely to change, far as I know its never been fixed in the previous 17.1 rom either. As retiredtab mentions in point 1, camera use is not a big need or he has alrady tried to fix it and not been able to.

I did everything wrong with a working result:
-My Starting point: LineageOS 17.1 (ripee) installed
- Backup of User Data @ Android System (copy to MicroSD)
- Updated the TWRP version to the recommended in TWRP (coming from ripee version for 17.1)
- Boot to System to ensure it's still working
- Backup everything in TWRP
In one batch without booting in between:
- I dirty flashed "lineageOS 18.1" over "lineageOS 17.1 (from ripee)"
- Flashed the Arm64 version for Android 11 of "mindTheGapps" over existing "OpenGapps (for Android 10)"
- Flashed Magisk *.zip
- Deleted Cache and Dalvik
Boot to system and it's working perfectly so far
FYI.: Camera App "ProcamX" is working as well.
FYI.: Especially for lineageOS 17.1 users: I can confirm GPS is working (GPS Test Plus)
For sure I wouldn't recommend this procedure and maybe I will do a clean install later to gain smoothness and to make it stable in general but so far it's super nice, no bootloop, random restarts (BUT it's based on a few hour usage only) or whatever and a big thank you to ritiredtab

I have Magisk and safetynet pass flashed. I can download Netflix from Playstore but it doesn't play any content. It seems that Widevine / DRM is not part of the ROM at all as the App "DRM Info" doesn't show any Widevine information. In consequence Netflix doesn't play and stuck in "loading". Anyway it seems to enable some old DRM blobs can fix the issue like at least for L3 which is SD playback. Something like here needs to be added I think....:
https://review.lineageos.org/c/LineageOS/android_device_moto_shamu/+/339185
Didn't dig deeper into the topic so far. Just want to share the info.

As I listed in post #1, DRM L3 works as I check/test/verify ALL my public xda builds for the functionality in post #1 before uploading.
Here's the results of checking DRM with 4 different programs. Devcheck by flar2 is what I use to check all my ROMS for a variety of values and widevine DRM L3 (along with clearkey) is clearly shown. Device Info HW and DRM Check also show widevine properly.
DRM Info by Android Fung is the only one that cannot show the widevine information which may be due to a bug in this program or it's poorly written and being denied by selinux enforcing.
DevCheck and Device Info HW are both ad free while DRM Check and DRM Info are infested with ads. The latter 2 are programs I will never use again.
In addition, DRM Info by Android Fung shows this in the logcat
Code:
GooglePlayServicesUtil: com.androidfung.drminfo requires the Google Play Store, but it is missing.
As I mentioned several times, I do NOT and will NOT install any gapps.
Your link to gerrit regarding DRM is already in my code (done a bit differently, but works as clearly shown by Devcheck).

@retiredtab Thanks for the detailed reply. You are right. I See Widevine L3 in other Apps as well. Shame on me '-'. Even Netflix itself gives this Info... Anyway... Playback is not starting while preview videos are working. Tried already a couple of versions without success and checked the permissions. As I'm customized with Magisk the rootcause could be on my side for sure. Prime Video is working by the way. Would be nice to know if a clean install has the same behaviour.

There's a reason why I always recommend clean installs. When you don't do it, it leads to unexplained problems. If Prime is working, that suggests DRM L3 is working.
If a clean install doesn't work with Netflix, then see FAQ 9 and send me the logs (zipped). There's no guarantee that it will show anything wrong or if I can fix it. I don't have/use Netflix or any other $treaming service.
Having said that, I do build other roms like the T810 (S2 2015 exynos model) and others have commented that they do not need Magisk hide, root, etc to get Netflix shown in the playstore because my T810, like this T813, is selinux enforcing. They report that the T810 shows up as "device is certified".
Again, since I don't use gapps, I cannot confirm if "device is certified" is true for T813, but if it is, then Netflix should show up without Magisk/hide, root, etc. If it does show up, it's a bonus. If the T813 shows up as "device not certified", I have no plans to fix this as I don't use gapps.

@retiredtab I'm not sure if I will do a clean install as the system is working quite well expect Netflix and at the end of the day it's not super important for me. In case I do a clean install I will provide a log and be thankfull for the offer to fix things
The chances to have an indication is maybe low in the logs as Netflix loops in the loading screen without an error at all. Anyway I don't want to waste your time with this topic currently as I cleary didn't follow your instructions by doing a dirty flash and so on. And again... Super nice to have this rom which gives my tablet a 2nd life. Thanks a lot.

I don't really care about using Netflix on this device, but figured I'd let you know that I'm having the same issues after a clean flash. Will try and grab a log later.

I have this strange problem
I have two tablets SM-T813 and SM-T819.
I installed Lineage os 18.1 on SM-T813 and SM-T819 (I modified the installer). On the T813 it booted without any problems. On the T819, on the other hand, it stands in bootloop. I went into recovery and there were no files in INTERNAL STORAGE, it was empty. To T819 I need to install some file or something so that it can start reading Memory and come out of bootloop?

As I mentioned in the FAQ, there's nothing I can do without the T819 physically in my hands. If the T813 worked on T819, then it's a bonus. If not, it was worth a try.

[UNOFFICIAL][ROM]ALPHA LineageOS 20 for SM-T813 - June 23, 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.
This is ONLY for the T813. I do not have and will NOT build T713, T719 and T819. See post #2, FAQ 20. Any questions asking to build these will be ignored.
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 ,boot loop, complete loss of data or non booting device or you not being able to revert back to your old rom.

Known issues/What doesn't work/what's not tested
NOTE: If any following features are important to you, don't use this rom as I will not be fixing them because I
i. don't use/need that feature
ii. already tried fixing it and couldn't succeed and won't spend anymore time on it.
1. Stock camera doesn't work at all (reason i and ii). Starting with LineageOS 19.1 and higher, camera API functionality (pictures and videos) isn't even recognized by the OS.
2. fingerprint (reason i). I never use it and I see it doesn't even load correctly in the logs.
3. ARM64 gapps (reason i). 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 ARM64 gapps.
There are various gapps projects (at least 5 in 2023). 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/days doing your own research. My rom works by itself fine without gapps. DO NOT talk about gapps in this thread.
4. full disk encryption has been deprecated in Android 13 (LineageOS 20).
5. If you restart the device with the purpose to reboot it and the usb cable is plugged in, the device will not reboot and stay in charging mode. Simply unplug the usb cable, wait 15 seconds and restart the device.

Frequently Asked Questions. You MUST READ this before posting any questions. If you think this is unreasonable, then find another rom. Thank you.
Q1. Where are the source and kernel source files?
A1. The kernel source files are at
https://github.com/syphyr/android_kernel_samsung_msm8976/tree/lineage-16.0
The device tree files are at
https://github.com/retiredtab/msm8976-common/tree/lineage-20
https://github.com/retiredtab/gts210vewifi/tree/lineage-20
The vendor tree files are at
https://github.com/retiredtab/proprietary_vendor_samsung_msm8976
The manifest.xml (or roomservice.xml) and build instructions for LineageOS 20 are at
https://github.com/retiredtab/LineageOS-build-manifests/tree/main/20/msm8976
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 Jan 2023 with no major issues. I suggest you do a clean install, see FAQ 11, and flash this 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. 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 3.6.2_9-0. Do not use any other version including the "latest".
https://dl.twrp.me/gts210vewifi/
I will not answer questions if you don't use this exact TWRP version.
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. In addition, I don't run Windows OS at all.
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 build Android 14 and higher for this device?
A10. Any questions on higher Android versions will be completely ignored. I do this in my free/spare time and will not be subject to any ETAs or demands. If you want a higher version, the source code is freely available as per FAQ #1 and you can build it yourself.
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 20 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.
You MUST FORMAT DATA in TWRP so backup your files first to some external storage (external microsd or PC).
NOTE: After you do the above, first boot (without gapps, magisk, etc) will take about 90 seconds. It may pop with a message saying "System UI isn't responding". Hit close app and then reboot the tablet again.
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 ARM64 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".
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.
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.
Q15. What speed up/optimization tips do you suggest?
A15.
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. Use a web browser like Brave that has built in adblock and privacy features.
4. Use newpipe to watch your streaming content. It has built in adblock so you don't have to watch forced ads.
5. Look for apps that are open source, ad free and lightweight.
Q16. Does this rom support Magisk for root?
A16. I don't use Magisk. Magisk is always being updated to fool Google's certification process which may or may not work.
Q17. Will this rom ever become official?
A17. With 19.1 and up, legacy devices like ours will NEVER be official due to lack of ebpf support. See https://lineageos.org/Changelog-26/
Q18. What is the difference between this rom and others?
A18. This rom tries to be pure LineageOS with little to no modifications.
Q19. Will there be any major 20 code modifications in the future?
A19. 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 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.
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. To be clear, I will NOT build T713, T719 and T819.
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. Does this rom support OTA updates?
A22. No and I have no plans to add that functionality.
Q23. Why is there no LineageOS 19.1 build?
A23. I actually had a private 19.1 build back in Dec 2022, but stock camera didn't work at all so I decided to try build 20 to see if stock camera works in 20 (it does not either). Since I'm the sole builder for 18.1 and 20, I don't want to build, maintain and test 3 roms each month. Since 19.1 and 20 are very similar, I decided to just do 20 and drop 19.1 altogether. For those that need stock camera to work, use 18.1 (with caveats) or another rom where it works properly.
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-T813/20/
