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.

Thx a lot. I never expect my P580 will have android 11.

I just want to report when using onenote. The samsung stock rom when spen hover on screen, the physical function key, back and recent apps, will disable. However, the lineageOS 18.1 seems working the both function key and spen at same time.
Another issue is my P580 sometimes have spen inking delay issues, especially when I zoom to about 150%.
Any comment and help would be appreciated

Thanks for providing new Android Versions for such a old device.
It seems to work great so far.

What are the reasons that roms like this are not official?

Trying to enable the on-screen nav bar and disable the hardware buttons. When I select System -> Buttons -> "Enable on-screen nav bar" however the hardware buttons are still active. Does anyone know how to completely disable the hardware nav buttons?

Thank you @TALUAtXDA for maintaining up-to-date software for this hardware - very much appreciated!

A minor "issue" that I observe updating this device (SM-T580, using NikGapps-core-arm64-11-20210501-signed) from lineage-18.1-20210508-UNOFFICIAL-gtaxlwifi to lineage-18.1-20211023-UNOFFICIAL-gtaxlwifi: There seems to be a change in policy what kind of notifications can be "muted"/disabled. When installing/using Google Input for Pinyin ("Google-Eingabe für Pinyin"), I had seen before also with other devices that it asks for Google account permission incl. notification. As everything works flawless without, I never provided this permission and was able to disable the notification. Since the update, I receive the notification again and the setting (account status ("Kontostatus") in Android system ("Android-System")) is fixed on enabled (greyed out).

Anyone aware whether this is a general change in Android or is it specific to this build and could be changed? Or any other idea (excl. options that require root)?

For SM-P580/gtanotexlwifi: https://drive.google.com/file/d/1-bp8Z2iDyMV9AeSLVlqMipN17kzGEWfE/

Changelog:

  • 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.
Enjoy.

    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 are a continuation 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 his builds without doing anything further.

    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 planning to try to setup sources to make builds for the LTE variants sometime in the future whenever I have the time to.

    For SM-T580/gtaxlwifi:

    Latest build from 20211114 (with security patch level 20211105): https://drive.google.com/file/d/15KxgVkH_5X8e45Cq-KDsqvR6lZ-rsZwE/
    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 20211114 (with security patch level 20211105): https://drive.google.com/file/d/1-bp8Z2iDyMV9AeSLVlqMipN17kzGEWfE/
    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 an unofficial TWRP build from an updated device tree and with a kernel compiled from the same sources used for these LineageOS builds that must be used.
    Download link for an image of it: https://drive.google.com/file/d/1eNOn9IRCj98dpx7fCSnPBQu0FIOsKZrr/
    Download link for a tar archive containing it for installation via Odin in the AP slot: https://drive.google.com/file/d/1oTurdJuNSQpl2PrEJDZpNjKdCTMapokE/
    Note that this is a second build, that has a ramdisk compressed using LZMA compression, rather than using standard gzip compression as it was in my first build since it's too large with it.

    Changelogs:

    Previous releases:
    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 are unsure on how to get either, there is good documentation out there for how to do so.

    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.

    • 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.)
    Enjoy.

    For SM-T580/gtaxlwifi: https://drive.google.com/file/d/15KxgVkH_5X8e45Cq-KDsqvR6lZ-rsZwE/
    For SM-P580/gtanotexlwifi: https://drive.google.com/file/d/1-bp8Z2iDyMV9AeSLVlqMipN17kzGEWfE/

    Changelog:

    • 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.
    Enjoy.
