I certainly download a wrong NickGspps last time ( i do not keep it). Yesterday i pay attention to reload the right Core one and retry to install new ROM release and NickGapps without any issue. Evething is fine...

@TALUAtXDA Got to say, tried the android 12 roms for this but got back to this rom. Performance is much much better with this android 11 rom yet.
Not sure if android 12 is worth it yet for this device.

Hi there,

I have question for you.
I have now installed Lineage in my tablet. Let's say I want to upgrade to a new version of lineage.
What's the procedure?
Thanks in advance...

Download latest zip.
Reboot into recovery.
If it's a major update (eg. 17.1 to 18.1), format data and flash the zip. If not, just dirty flash it without formating.
Reboot into system.

Uhm... so you're saying that every major update it's better doing a clean install, erasing all data from the tablet? It's a bit intrusive...
To clear up any concerns...
To update to a newer build for the same LineageOS/Android version with an existing installation, as mentioned before, all that is necessary is the installation of the newer build. There aren't any issues with doing so, and the possibilities of any (unexpected) issues are really minimal.

For major updates specifcally, to install new builds for new major Android/LineageOS versions, it would only be necessary to format the system partition before installing such a build, install the build, and then install new versions of packages (such as Google apps, if you need them) compatible with whatever newer version of Android. I've kept my exact same installation on my tablet for a few years from when I ran LineageOS 16.0 with no problems, just following that procedure for every new major version. It's just best to make backups of data before attempting an update to a new major version, and you'd also possibly need to install the latest version of TWRP at whatever time.

Indeed, needing a clean install every new major version is intrusive, and pretty inconvenient. As long as it's done properly as I described, problems would be avoided.

Thanks for your reply @TALUAtXDA , seems all clear. So...
- New build/same OS/ANDROID version: dirty install with twrp, without wiping anything.
- Ne build/ different OS/ANDROID version: clean system partition with Twrp and then flash new build and gapps (and Magisk maybe? You tell me)

Correct me if I'm wrong.

I have a big problem with football manager 2022. When I put the game in the background or simply shut down the screen, in a few minutes the game reset itself and starts from the beginning. Unfortunately its very annoying. I've already set the apk in the "without optimisation" group and set the tablet for maximum performances but nothing. The game keeps shutting down and show 0 minutes of activity in the background. There's a way to solve this situation?

Thank you so much for bringing lineage os to my P-580, I tried making this myself some years ago but failed and gave up, all I achieved was a buggy twrp build which allowed me to install a crappy debloated rom based on stock oreo that I made and never released to the public (system settings were so bugged hahaha)

I installed your rom and can say gladly that it runs excellent, but I found an issue that is disabling for the ones that use the s-pen for handwriting stuff.

When using apps like squid or inkredible, if you release or start a normal touch input (it being from your palm resting on the tablet screen while writing) the s-pen input gets "discarded", I don't know if that's the best word to describe it, but surely this video explains it better.

I think that this happens due to the s-pen not disabling normal touch inputs while the pen is touching the screen, which is something that it does on stock samsung roms.

If you want me to help you test new builds to try fixing this, hit me with a PM!

Any chance of getting a t585 build? I need the lte.
I'm afraid not.

When thinking about trying to get a build up for the LTE variant initially, I underestimated the complications in doing so and misjudged the whole process. Adding all of the stuff for mobile networking functionality and the different GPS hardware in the LTE variants (T585s and P585s) to my existing sources actually seems to be quite involved, and getting it all to work properly to provide the mobile networking and GPS functionality would be more difficult than I ever thought.

I also thought I could take and adapt the stuff for the modem and GPS hardware from Valeras (the previous maintainer working on stuff for these devices) old device tree for the LTE variant to my device tree, but after looking through it all and thinking in more depth about it, I realized that isn't easily possible. My current sources for the WiFi-only variants have had too many changes applied to them to simply do that, and I wouldn't want to take much from it since it really isn't in very good shape. Along with that, I wanted much newer proprietary blobs from some newer version of Samsung's stock firmware for some device than were used before, and this has its own complexities since I couldn't be certain if any I extract would work on these specific tablets with their specific hardware, and about what I'd need to do with them to get them to work if that's at all possible.

On top of all that, if I was to go through with trying, and it didn't all go really well, I'd probably understandably lose patience from testers from the likely many things I'd need to try to get it all working, and it would all take an unbearably long amount of time, and in the end, I would no doubt not end up with anything that works from all of that.

The only real way to go forward with it would be to get an LTE variant device myself, and use it to bring things up. A short while ago, I looked on eBay UK for the few listings for one. At the start of my search, I saw a few listings for the LTE variant that were decent. Naturally, they got bought up and vanished really quickly, much too quickly for me. Afterwards, I couldn't find any other decent listings for a long time, so I gave up for then. I'm probably going to look again in the future, and hopefully buy one, especially as I still want another one of these tablets.

I'm also finding that time is becoming more and more scarce for me, and I don't have as much interest or motivation as I used to with this Android stuff, especially as I'm now content with the state of things for the WiFi-only variants, and I'm now shifting more to other interests. That has had an effect as well.



So, finally, in short, the complexities and likely chance of failure due to such complexities without having direct access to an LTE variant device make it seem to not be truly worth attempting to get working sources up for the LTE variants, and make builds. Realistically, I'd need direct access to the LTE variant, and I may acquire one sometime in the future. In the meantime, sadly, I won't have anything for them, and the builds for the WiFi-only variants will continue to be the only available option.

Thank you so much for bringing lineage os to my P-580, I tried making this myself some years ago but failed and gave up, all I achieved was a buggy twrp build which allowed me to install a crappy debloated rom based on stock oreo that I made and never released to the public (system settings were so bugged hahaha)

You're very welcome, and hmm, alright.

That problem has been reported a few times before.
To fix it (in one way that's preferable), I'd need to apply changes to the kernel (more specifically, the touchscreen and wacom drivers in it) like the changes in this commit: https://github.com/LineageOS/android_kernel_samsung_gta4xl/commit/8f0b9dedfad0f52279f91ff2a69ca61fc5227066
I haven't gotten around to trying to adapt those changes yet to the drivers used for the P580. Not sure about it at the moment, but I'll try later. If I get anything, I'll send you an installable package with a new kernel (rather than a whole new build) in a PM for you to test out and see if that problem no longer exists.
For those who need a fairly recent build for the LTE version of this tablet, I found this one:

It seems quite shady. It's just a build and nothing more, and there's probably nothing about it elsewhere. There's no information about that build, such as the sources that were used to build it, or any details about the state of it.

I'd suggest against trying to use it.

New releases for 20211222

Downloads:
For SM-T580/gtaxlwifi: https://drive.google.com/file/d/1YSM8cQF40-dFS7C6KQYRIeYy4St8EAtI/
For SM-P580/gtanotexlwifi: https://drive.google.com/file/d/1MXIzM6HXtf6XjaiMJG49jb6naweaAv9E/

Changelog:

  • Latest updates from Lineage, including the 20211205 Android security updates.
  • There are some updates from the 4.4 Android common kernel to the kernel.
Merry Christmas to everyone, and, of course, enjoy.
Great release, the Tablet (SM-T580) works smooth, fast and pretty well except a WLAN issue. WLAN isn't working well if the router delivers 2,4 and 5 GHZ band within one SSID. The connection is always flapping and didn't get stable. It works only stable while connection to a 2,4GHz band hotspot.

Any idea how this can be solved or if it will be fixe in a future update?

I have the same setup, but without any issues. In fact, 2.4/5 GHz switching works really well depending on signal strength, but stays stable once the tablet stays in the room.

    Are there still some bugs?
    All of the currently known bugs are listed under my "known issues and workarounds" section in my original post (although note that there will be a few fixes for issue 3 and Sony DualShock 4 controller support in my next releases).

    This is LineageOS 18.1, which is based on Android 11, for the WiFi-only variants of the Samsung Galaxy Tab A 10.1" (2016), with model SM-T580 and codename gtaxlwifi, and the Galaxy Tab A 10.1" (2016) with S-Pen, with model SM-P580 and codename gtanotexlwifi. LineageOS doesn't need much of an introduction - It's a well-known custom firmware/Android distribution.

    As was always planned, my LineageOS 18.1 builds continue on from @followmsi's LineageOS 18.1 builds that were intended for use by users. To update from his builds, my builds can simply be installed on top of an existing install from his builds without doing anything further (or "dirty flashed").

    Downloads:
    Note: While these builds are mainly intended to be used on the WiFi-only variants of these devices, they can be installed and used on LTE variants if you can go without mobile networking (of course), GPS and vibration.
    I'm only going to try getting builds up for the LTE variants if I get one in the future. Trying to do so without direct access to an LTE variant device is very difficult and not really feasible (as I've realized after thinking in much more depth about it since thinking I'd be able to do so without an LTE variant device a long time ago).


    For SM-T580/gtaxlwifi:

    Latest build from 20220423 (with security patch level 20220405): https://drive.google.com/file/d/18de93DpX4SHuVE-O_RQigwO8_XvYka-j/
    Folder for builds (which includes text files with MD5 and SHA256 checksums for builds, and another folder within it containing some previous builds): https://drive.google.com/drive/folders/1wuirD9cyoguv7CQdEO5ymZ911k2ASKKD

    For the T580, the latest official TWRP build from here should be used. If installing a build for the T580 to the LTE variant, with model SM-T585 and codename gtaxllte, keeping in mind some functionality will of course be missing as described in my note, the latest official TWRP build for gtaxllte from here can also be used.

    For SM-P580/gtanotexlwifi:
    Latest build from 20220423 (with security patch level 20220405): https://drive.google.com/file/d/1C99uqa_IFHMUMp7SqlwgN3sIu4GMuY8L/
    Folder for builds (which includes text files with MD5 and SHA256 checksums for builds, and another folder within it containing some previous builds): https://drive.google.com/drive/folders/1fVGx1xGUxAtTvE0rG-OidwbXLM_93om2

    For the P580, I've made unofficial TWRP builds from an updated device tree and the same kernel sources used for these LineageOS builds that must be used.
    Download link for an image of my latest TWRP build: https://drive.google.com/file/d/1TAFLVpxdYQNvfvUPS_BGKx3imphR1Wd2/
    Download link for a tar archive containing it for installation via Odin in the AP slot: https://drive.google.com/file/d/1Ay55ntZj7Uptzm--hiCaeG1C5lamQ1fG/

    Changelogs:
    Releases for 20220423:
    • Latest updates from Lineage, including the 20220405 Android security updates.
    • The tablet product characteristic has been added back after being mistakenly removed - Places where the device was referred to as a phone (such as the "About phone" section in settings) will now refer to it as a tablet again.
    • Some small improvements from my fixes for LineageOS 19.1 have been applied to the sepolicy containing the SELinux rules.
    • Some other miscellaneous cleanups have been done.
    • A few updates from the 4.9 Android common kernel and Samsung's A600FNXXU9CVB1 kernel sources have been applied to the kernel.
    Previous releases:
    Releases for 20220325:
    • Latest updates from Lineage, including the 20220305 Android security updates.
    • The previously used 32-bit GPS blobs have been replaced with 64-bit blobs from Samsung's A810SKSS2CTI1 firmware.
    • The XTRA servers for Assisted GPS have been switched to the servers used in Samsung's stock firmwares - This fixes Assisted GPS, which turned out to actually not appear to work with the previous XTRA servers.
    • Even more small miscellaneous cleanups have been done.
    • There are some updates from the 4.9 Android common kernel to the kernel.
    Releases for 20220224:
    • Latest updates from Lineage, including an increase of the Android security patch level to 20220205 (just an increase as interestingly, for this month, there aren't any (relevant) security updates).
    • The WiFi firmwares have been updated from Samsung's T395XXSDCVA1 firmware.
    • There are some final updates from the 4.4 Android common kernel (which is unfortunately now also discontinued along with Linux v4.4) and some updates from the 4.9 Android common kernel to the kernel.
    • [SM-P580/gtanotexlwifi only] Touch input and input from the back and recent apps keys is now ignored when the S-Pen is in use. (Thanks to @unknowwiiplayer for testing the changes for this)
    Releases for 20220122:
    • Latest updates from Lineage, including the 20220105 Android security updates.
    • There are some updates from the 4.4 Android common kernel to the kernel.
    • Some changes have been applied to a few drivers specifically for Android in the kernel (mainly the binder driver) from the 4.19 Android common kernel for Q.
    • A few changes from the 3.18 Android common kernel that were missing from the kernel have been applied.
    Releases for 20211222:
    • Latest updates from Lineage, including the 20211205 Android security updates.
    • There are some updates from the 4.4 Android common kernel to the kernel.
    Releases for 20211114:
    • Latest updates from Lineage, including the 20211105 Android security updates.
    • The WiFi driver has been switched from being a kernel module to being built into the kernel. This may improve reliability for enabling and disabling WiFi and the WiFi hotspot very slightly.
    • The libexynoscamera3.so library has been updated from Samsung's P580ZSS1CTI1 stock firmware - This improves the situation with the issues with stretched/squashed camera previews for images and stretching/squashing in videos at some resolutions.
    • The MFC (Multi-Format Codec) firmware has been updated from Samsung's A305FDDU6CUI3 firmware.
    • As the oldest proprietary blobs are now as in Samsung's P580ZSS1CTI1 stock firmware (with a few exceptions), the vendor security patch level has been increased to 2020-09-01, which is the security patch level that firmware has.
    • Configuration files for media codecs and profiles have been updated from Samsung's T580XXS5CTK1 stock firmware.
    • Most SELinux rules that are technically not allowed (by neverallow rules) have been replaced with much better rules or removed.
    • There are some (final) updates from the (unfortunately now deprecated so no longer updated) 3.18 Android common kernel, some updates from Linux 4.4, and a few updates from Samsung's J600FPUUACUH2 and A720SKSU5CUJ2 kernel sources to the kernel.
    Releases for 20211023:
    • Latest updates from Lineage, including the 20211001 Android security updates, and a fix for the issue where the media controls in the notification panel squash the quick settings tiles and make it impossible to swipe through them when in landscape.
    • Workarounds for an issue with rebooting to recovery and download mode from system using the advanced restart menu or the reboot command in a shell have been replaced with a proper fix.
    • Yet further slight miscellaneous cleanups have been done.
    • [SM-P580/gtanotexlwifi only] A problem where S-Pen input wasn't registering in the right directions in orientations other than portrait, as the axes for it didn't change on orientation changes accordingly, has been fixed by enabling orientation awareness for it (Thanks to @retiredtab for sharing that fix).
    • [SM-P580/gtanotexlwifi only] The cursor that appeared when using the S-Pen has effectively been disabled by setting the device type for the S-Pen input to a touchscreen (Thanks to @Acatzin for the hint for this).
    • [SM-T580/gtaxlwifi only] The system image size has been increased from 3072000000 bytes to 3145728000 bytes, which is the size of the system partition on Korean and Chinese variant T580s and T585s, and the smallest system partition size out of all T580s and T585s.
    • [SM-P580/gtanotexlwifi only] The system image size has been decreased from 3072000000 bytes to 3045064704 bytes, to accomodate for the SM-P583s system partition which has that size. With this change, it should now be possible to install this latest build for the P580 on the P583 and for it to boot fine, since the P583 basically seems to be a P580 but for China, although I can't be certain on that.
    • There are some updates from the 3.18 Android common kernel and Linux 4.4 to the kernel.
    Releases for 20210922:
    • Latest updates from Lineage, including the 20210905 Android security updates.
    • The ZRAM size has been increased to 768MiB.
    • Even further miscellaneous cleanups have been done.
    • The 32-bit wcnss_filter binary, used for Bluetooth, that was used previously has been replaced with the 64-bit wcnss_filter binary from Samsung's A520FZTU4BRB1 firmware.
    • There are some updates from the 3.18 and 4.4 Android common kernels and Linux 4.4, a few changes backported from mainline Linux, and also a few other insignificant changes to the kernel.
    • An issue where there was additional extremely quiet high-pitched noise from the right speaker has been fixed. (Thanks to @Kostareka for reporting it. It likely would've gone unnoticed for at least a very long time into the future otherwise.)
    • First proper release for the P580.

    Release for 20210810:
    • Latest updates from Lineage, including the 20210805 Android security updates.
    • This is my first build that is signed using my own release keys. This change was removed in the second build released for 20210810 (with "-R2-Test-keys" in the filename).
    • The BSP sources have been redone to closely match what has been done with the new exynos7880-specific part of Lineage's BSP sources, and with that, there are now more exynos7870-specific changes to the open source gralloc that is in use.
    • Some further small miscellaneous cleanups have been done.
    • There are some updates from the 3.18 Android common kernel and Linux 4.4 to the kernel, and a few other insignificant changes.
    Release for 20210709:
    • Latest updates from LineageOS.
    • Merges of the latest changes from AOSP for repositories forked by Lineage have been picked to skip the wait for them to be merged (repopick -t android-11.0.0_r39), and the rest of the repositories not forked by Lineage were additionally switched to the android-11.0.0_r39 tag, for the 20210705 Android security updates.
    • A patch to the PermissionController app has been applied that adds the FAKE_PACKAGE_SIGNATURE permission group to it - The signature spoofing permission can now be managed through the permission management interface at Settings -> Privacy -> Permission manager.
    • The audio outputted from the audio jack while playing media will now be noticeably louder, as the headset "DAC1 playback volume" for media has been increased to the maximum of 175 from 162.
    • There are some updates from the 3.18 Android common kernel and Linux 4.4 to the kernel.
    • A few patches have been applied to the qcacld-2.0 WiFi driver in the kernel, which are mainly vulnerability fixes.
    Release for 20210617:
    • Latest updates from LineageOS, including the 20210605 Android security updates.
    • The WiFi and Bluetooth firmwares have been updated from Samsung's A720SKSU5CTL2 firmware.
    • The qcom_cfg.ini configuration file for WiFi has been imported from Samsung's A720SKSU5CTL2 firmware - A change within it appears to have made WiFi more reliable.
    • The sensors.universal7870.so library has been updated from Samsung's stock P580ZSS1CTI1 firmware.
    • The health HAL has been upgraded to version 2.1.
    • There are a few other small miscellaneous changes (mostly small cleanups).
    • There are many updates from the 3.18 Android common kernel and Linux 4.4 to the kernel.
    • Some unnecessary drivers have been disabled in the kernel.
    • The sdfat driver in the kernel, which is used for exFAT filesystem support, has been updated to version 2.4.5.
    • A few changes have been imported to the MMC block device driver in the kernel from Samsung's M105GDXS6CUD4 kernel that fix extremely rare kernel panics that occurred when there was an error with a MMC device (mainly with SD cards).
    • The fix for an issue where the duration of videos that are taken is lengthened by the time spent in deep sleep/suspended that was previously used has been replaced with a better fix in the Exynos fimc-is2 driver in the kernel.
    Release for 20210508:
    • Latest updates from LineageOS, including the 20210505 Android security updates.
    • New SELinux denials with Android 11 have been addressed, and with that, SELinux is now set to enforcing by default, and the sepolicy, which contains the SELinux rules, has been rewritten almost entirely, and is now of much better quality.
    • Some changes have been imported to libbt-vendor from https://github.com/LineageOS/android_hardware_qcom_bt on branch lineage-18.1-caf.
    • BPF offloading for tethering has been disabled.
    • The audio HAL has been upgraded to version 6.0.
    • The rampatch_tlv_tf_1.1.tlv firmware for Bluetooth has been updated from Samsung's stock T585XXS6CTJ7 firmware.
    • There are some updates from the 3.18 Android common kernel and Linux 4.4 to the kernel.
    • Some tcp_info-related patches have been applied to the kernel, and with that, a workaround, a patch titled "TcpSocketTracker: Opt-out for TCP info parsing on legacy kernels", is no longer used since it's no longer necessary.
    • A workaround that was used to get USB tethering and Bluetooth tethering to work is no longer used, and has been replaced with a proper fix (enabling CONFIG_NETFILTER_XT_TARGET_CT in the kernel).
    Release for 20210407 (My initial 18.1 build. This changelog continues on from @followmsi's last 18.1 build that was intended for use by users):
    • Latest changes from LineageOS. The crashes that occurred when setting a new wallpaper that were discussed earlier in this thread appear to have been fixed.
    • Merges of the latest changes from AOSP, including the 20210405 security updates, have been picked to skip the wait for them to be merged. (repopick -t android-11.0.0_r34)
    • The same workaround that was used on 17.1 to get USB tethering and Bluetooth internet access sharing to work has been forward-ported and applied.
    • vintf manifest override enforcement is now enabled.
    • The vendor/lib[64]/egl/libGLES_mali.so blobs are now symlinked to vendor/lib[64]/vulkan.exynos5.so, rather than copied to vendor/lib[64]/hw/vulkan.exynos5.so - This is a proper fix for Vulkan support.
    • RSA key verification for ADB is enabled again, and ADB isn't enabled by default and on boot anymore.
    • There are some updates from the 3.18 Android common kernel and Linux 4.4 to the kernel.



    Known issues and workarounds (if any):
    Issue 1: Occasionally, when trying to select quick settings tiles in the notification panel, it will crash to the lockscreen.
    I have no idea about this issue at the moment. It seems like some type of generic systemui crashes.

    Issue 2: Camera previews for images to be taken at resolutions with aspect ratios other than 16:9 using the rear camera are squashed from 16:9 (while final saved images at any resolution are unaffected by any squashing), and videos taken at some resolutions are affected by similar issues with squashing in previews, and, in a smaller set of resolutions, also in final saved video files. (Note that these issues don't affect the front-facing camera)
    Somewhat of a workaround to issue 2: Use resolutions at which there are no issues with squashing from 16:9.

    Issue 3: the on-screen navigation bar feature that can be enabled with the option at Settings -> System -> Buttons -> "Enable on-screen nav bar" doesn't work properly.

    To report further issues, get a log from logcat and dmesg. If you're unsure on how to get either, there's good documentation out there for how to do so.

    A manifest containing all of the necessary repositories to make a build for either the T580 or P580 is in this repository on branch lineage-18.1: https://github.com/TALUAtGitHub/gtaxlwifi-manifests

    Thanks to:
    @Valera1978 - for all of the previous work for the T580 (and T585) long ago, and for providing his old BSP sources without which the previously used open BSP sources wouldn't have been possible.
    @followmsi - for fixes to various issues and other improvements, for useful information, and for working with me on much of this stuff.
    Anyone who has previously tested anything new I've put up for testing, reported results, and gave details for me to get it working if it was necessary.
    The Lineage team - for the Android distribution itself.
    ...and everyone else who has worked on anything that is in use.

    For SM-P580/gtanotexlwifi: https://drive.google.com/file/d/1niGeY4cNDy5OAhoJd04P5MPQci3ztC9W/

    Changelog:

    • Latest updates from Lineage, including the 20211001 Android security updates, and a fix for the issue where the media controls in the notification panel squash the quick settings tiles and make it impossible to swipe through them when in landscape.
    • Workarounds for an issue with rebooting to recovery and download mode from system using the advanced restart menu or the reboot command in a shell have been replaced with a proper fix.
    • Yet further slight miscellaneous cleanups have been done.
    • [SM-P580/gtanotexlwifi only] A problem where S-Pen input wasn't registering in the right directions in orientations other than portrait, as the axes for it didn't change on orientation changes accordingly, has been fixed by enabling orientation awareness for it (Thanks to @retiredtab for sharing that fix).
    • [SM-P580/gtanotexlwifi only] The cursor that appeared when using the S-Pen has effectively been disabled by setting the device type for the S-Pen input to a touchscreen (Thanks to @Acatzin for the hint for this).
    • [SM-T580/gtaxlwifi only] The system image size has been increased from 3072000000 bytes to 3145728000 bytes, which is the size of the system partition on Korean and Chinese variant T580s and T585s, and the smallest system partition size out of all T580s and T585s.
    • [SM-P580/gtanotexlwifi only] The system image size has been decreased from 3072000000 bytes to 3045064704 bytes, to accomodate for the SM-P583s system partition which has that size. With this change, it should now be possible to install this latest build for the P580 on the P583 and for it to boot fine, since the P583 basically seems to be a P580 but for China, although I can't be certain on that.
    • There are some updates from the 3.18 Android common kernel and Linux 4.4 to the kernel.
    As usual, enjoy.

    • The WiFi firmwares have been updated from Samsung's T395XXSDCVA1 firmware.
    • There are some final updates from the 4.4 Android common kernel (which is unfortunately now also discontinued along with Linux v4.4) and some updates from the 4.9 Android common kernel to the kernel.
    • [SM-P580/gtanotexlwifi only] Touch input and input from the back and recent apps keys is now ignored when the S-Pen is in use. (Thanks to @unknowwiiplayer for testing the changes for this)
