I am checking which build I did last on my tab - will post it here.
sorry about the old link my bad...

However, a while back when I started this, I did read they were stopping support for this in Jan 2021. Maybe, that's it now. Do not quote me on it - but maybe march 2021 or April 2021 is the last update.

My last one is also March 26th - and unable to get a direct link for 2nd, 9th April from the tab - get dl errors when I try. Tried to download from the links above djase but my computer does not like any of the two links - so cannot dl it.
I guess wait a little to see if the servers get fixed as no one seem to have shared any of the April updates.
Except above lol

they seem to have removed it from here too: https://download.lineageos.org/chagallwifi

Anyone is using Netflix with this? I get a 5.10 error when playing a movie for some time. Already tried:
* Removed LineageOS Root addon
* Installed Magisk
* Hide root to Netflix with Magisk Hide
* Installed module to remove some crypt library

Nothing helped.

Is this error due to the old android version?

Did a quick look on reddit and some ppl say fixing error 5.2 fixes error 5.1
 
I don't have a liboemcrypto.so?
I do not use NetFlix - just read a few posts regarding the DRM netflix uses on rooted devices, and was just trying to help with this video if it works...

you can maybe look further and ask here:

I just booted my device after 1-2 Years. It is on 20200118 build. Now sorry for asking but shouldt I dirty upgrade or do I have to wipe&clean install?

Now that I am seeing there is an official Lineage for this device...where is the difference to this unofficial version?

Has the update checker stopped working for anyone else or is it just me?
It says no new version found whereas I have just successively flashed like 9 nightlies to bring it up to date.

Currently using this ROM on my SM-T705Y, with klimtlte version. I use this tablet to only read epub books, you can say I am using it as an ebook reader. I have turned off the adaptive display brightness and generally set the brightness to low, have not installed Gapps, and only using clean LineageOS and apps are minimal and limited to only ebook reader apps, Tachiyomi, Fdroid, DuckDuck Go Browser. Also, I am using the deathly version and have set the CPU frequency to a minimum of 100 MHz and max 400 MHz, and have increased the charging current rate. I have to say, the battery life now is outstanding. With a full charge and causal 1-2 hours reading, I get around 2-3 days of battery life. The screen on time is around 10-11 hours with only causal readings. This is probably one of the best tablets made by Samsung. 6-7 years and it is still going strong to date.

    Does anyone have any solutions for this? Thanks a lot.
    Did you do a full wipe? You can even try format data (will delete your files in internal storage as well). Try without an sd-card at first.

    Hello,
    I have installed Lineageos 14.1 with the latest gapps but unfortunately a few things are not working.
    I can't download any apps from the Google Playstore. The download does not start.
    Also, the home button does not work (only to wake the device but not to return to the home screen). Fingerprint sensor setup also no longer works (it did in a previous version).
    Also, I cannot access developer options (error message: Developer options are not available for this user). However, I can not change the user or create a new one?

    Does anyone have any solutions for this? Thanks a lot.
    Try this for developer Options - but before make sure you looked correctly as it is in a different place to stock:
    select system (It's above about phone) > Tap Advanced and it's the second last option, if not:
    use TWRP to wipe Dalvik Cache, System, Data and Cache and then re-installed the ROM.

    info from here: https://forum.xda-developers.com/t/lineage-os-developer-mode-missing.3561945/

    for apps found this - maybe see if the same problem:
    https://www.lineageosrom.com/2017/02/how-to-fix-google-play-services-error.html

    Also found this:
    1. Use TWRP as your recovery loader
    2. Backup your image using TWRP
    3. Install the latest GApps - I use the Nano version
    4. Wipe the Cache after the install is complete
    5. Reboot (do not install Lineage) and wait for the system to settle
    6. Reboot into recovery (TWRP)
    7. Install the latest Lineage (I use nighties)
    8. Wipe the Cache after the install is complete
    9. Reboot and wait until everything loads
    10. Problem solved.
    Basically... install the GApps over the existing install, reboot in Lineage and wait, then reboot into recovery again and install the latest Lineage update. It's worked for me three times so far.

    Hope this will guide you where you need - I google a lot :)

    Yes - you need to update it from TWRP
    Reboot in recovery - find the LinegeOS folder where the download is and update from there - remember to clear cache/dev after

    Go to install

    find the downloaded install here:

    LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1.2 (Nougat), which is designed to increase performance and reliability over stock Android for your device.​

    http%3A%2F%2Fimg.imgland.net%2FBINawli.png


    Code:
    #include <std_disclaimer.h>
    
    /*
     * Your warranty is now void.
     *
     * We are 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 us for messing up your device, we will laugh at you.
     *
     */

    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. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    This thread is for Official LineageOS 14.1 builds for chagallwifi (SM-T800) The following will not be supported here:
    Custom kernels
    Mods
    Xposed

    I don't support Xposed and any logcat which includes a Xposed module will be ignored. You're kindly invited to not report bugs if you:
    Flashed a custom kernel
    Installed or did mods from untrusted sources
    Modified system files
    Have not attempted a clean flash

    http%3A%2F%2Fimg.imgland.net%2F_4JAwRZ.png

    First time flashing LineageOS 14.1 on your device, or coming from another ROM?
    Download the zip(s)
    Install a compatible Recovery
    Perform a nandroid backup of your current ROM (Optional)
    Wipe data/factory reset
    Flash LineageOS
    Install the Google Apps addon package (Optional)
    Reboot

    Make sure you have the Marshmallow bootloader. Guide is in the comments below.

    http%3A%2F%2Fimg04.imgland.net%2FAg8dlGr.png

    There will be a new build every week, every Monday.
    The builds will no longer be personally tested by me before being uploaded (but everything will probably be fine)
    Change logs will no longer be posted within every new build, but instead when the changes are uploaded to GitHub. I will try though to post changes for major bugs or fixes as they are released.
    Some builds might feature only minor changes, ie. only updating the LineageOS source

    How to update to Marshmallow bootloader (required for 20170324 and later builds)
    Updating the bootloader is very quick and doesn't wipe data or repartition the device.
    If the last Samsung ROM you had was 6.0.1 Touchwiz, you already have Marshmallow bootloader and don't need to follow these steps. (If you were on MM, and it still won't boot, follow the steps below)

    1. Download the bootloader-only Odin package: T800XXU1CPK2.tar.md5
    This has the latest Marshmallow bootloader (December 2016)
    https://www.androidfilehost.com/?fid=457095661767146298
    2. Download Odin 3.11
    You can skip this if you already have a working Odin
    https://www.androidfilehost.com/?fid=673368273298937183
    3. Shutdown your tablet and start it up by holding Power+Home+Volume Down to enter Download Mode. Volume Down is the one right next to the power button. Really shut it down and use this key combination, if you use Advanced Restart, or go into download mode via TWRP the bootloader won't change.
    4. Make sure the screen of your tablet has a green android symbol with a "Downloading..." text
    5. Open Odin3_v3.11.1.exe and follow the instructions in this image:
    http%3A%2F%2Fi.imgur.com%2F2LpBdo2.png


    If anything is missing, you WON'T flash bootloader successfully.
    6. Click Start. Your tablet will automatically reboot back into your ROM.
    7. To verify you have the new bootloader, you can run in terminal emulator "getprop ro.bootloader". It should say T800XXU1CPK2.

    Thanks @ZakooZ for the post!

    Replacement charging port installed and we have a booting tablet again! Woo! Work can begin again, though I do have to learn my way around it again with exynos, it's different then Snapdragon.

    Really appreciate your patience and understanding with how I was busy throughout the year etc! Thanks a mill!
