  • LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

    Your warranty is now void.

    I am not responsible for bricked devices, dead SD cards,
    thermonuclear war, or you getting fired because the alarm app failed. Please
    do some research if you have any concerns about features included in this ROM
    before flashing it! YOU are choosing to make these modifications, and if
    you point the finger at me for messing up your device, I will laugh at you.

    3rd PARTY ADDONS/MODS
    While we have no issues with people using supersu/magisk/xposed/custom kernels/etc, we can't provide support for users who have them installed.

    Thank you @LumenReaper for this build! (y)
    I can confirm fingerprint is not working, but this is no bigger issue to me.
    Flashed Magisk and changed fingerprint two times. But safetynet is still failing - no idea. My sim card is also not detected.
    I use the tablet for youtube and yatse mostly. Youtube Vanced workes fine and my Bose headphones are also connected and working.

    Thanks for installing. Glad to hear you're getting along with the current feature set. I should have mentioned that my tablet has WiFi only. Feel free to send me a log if you want, but I expect it will be difficult to fix it without the device itself.
    Personally, I have not had any problems with failing safetynet. In which situation does it cause you problems?

    Will continue with the fingerprint scanner as soon as I have time again.
    Looking forward to this ROM thank you.
    You' re welcome.

    I do not see any issues with failing safetynet so far. It was working in 17.1 so I just wondered about the error after changing the fingerprint of the device by the help of magisk.
    I will try to build the rom on my own with your sources - hopefully I can help with the non working SIM card.

  • I've installed this ROM but one thing I noticed is that the internal storage and the contents in it aren't visible at all on MiXplorer Silver (The file manager I use)
    It isn't visible at the default file manager too so I rolled back to Lineage OS 17.1
    I would appreciate if this is fixed @LumenReaper
    I cannot confirm this problem. The default files app shows me the internal storage and an SD card with content. If I would have had such a serious problem, I would not have published the rom yet.

    Have you done a clean flash? Have you tried the format data option in TWRP?

    Do you think this wll also work for the TB-X705F, the successor model?
    I don't know, do you use the TWRP of this series?

      Great work Lumenreaper! (now I need to find the courage to install it on the only operational tablet that I own :))
      I did manage to build it myself using Docker & the docker lineeage-ci-cd image (see https://github.com/lineageos4microg/docker-lineage-cicd )

      Merhaba,

      [USER = 9583233] LumenReaper [/ USER]!​


      Çalışmanız için teşekkürler, efendim!

      Söyleyin lütfen - Android 11.0'da yapılan Lineage OS 18.1?
      Bu konunun ilk başlığında bununla ilgili bir kelime yok.

      Cevabınız evet ise, bunun için Google Apps paketini nerede bulabilirim?
      Sormak, çünkü https://opengapps.org/ adresinde Android 11 için hiçbir şey yok


      teşekkür ederim

      Pico works well with 11 tests. I dond,t know english sorry. Google translate:)

      I love the rom, but after using it for a while, the power button does not turn off the tablet and the tablet freezes. I am using magisk. I wonder if this question has anything to do with magisk.
      Thank you LumenReaper
      I have used Magisk with 17.1, but not yet with 18.1. Are we talking about using the power button to turn off the screen or shut down the device?
      I've clean flashed Lineage OS 18.1 and I could see the internal storage now.
      But however, I came across a 2 issues:
      - The tablet sometimes turns off itself
      - The tablet turns off itself and boots to TWRP randomly.
      Because of these issues I've rolled back to Lineage OS 17.1 and I'll wait until Lineage OS 18.1 is really stable enough to use it daily.
      Glad to hear the internal memory is working for you now.
      Interestingly, these problems occur on my tablet in lineage 17.1 :).

      What is the twrp version you installed lineage 18.1 and 17.1 on?
      That will be interesting. After all, you two describe exactly opposite behaviour for 18.1. Personally, I had no such problems under 17.1 or in the last two weeks with 18.1.

      It will probably be very difficult to make progress here because I haven't had the problems until now and they only occurred sporadically on your system and I need a log in any case.
