LineageOS is a free, community built, aftermarket firmware distribution of Android 9 (Pie), which is designed to increase performance and reliability over stock Android for your device.
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. You can also view the Changelog for a full list of changes & features.
Installation instructions :
Be sure to have installed latest TWRP recovery (you can find it in downloads) and latest Android Lollipop (5.0.2 for matisse, 5.1.1 for millet) firmware
Download the latest build and GApps (ARM, 9.0, I advice pico package) - if you'll go to wipe even internal storage, put them on a microSD or an USB OTG, or copy them after wiping it
Boot to recovery mode
Wipe > Advanced wipe > Select system, data, cache and dalvik/art cache (and, if you want to clean more, select even internal storage, which deletes all the content in /sdcard) and do swipe to wipe. When it finishes, go to home page
Install > select ROM zip file > swipe to flash and, when it finished, go to home page
Do the same thing to flash GApps
Reboot > System
Update instructions :
Be sure to have installed latest TWRP build
Download the latest build
Boot to recovery mode
Install > select ROM zip file > swipe to flash and, when it finished, go to home page
Reboot > System
Known issues :
Magnetic cover doesn't trigger magnetic sensor (it works, but it's too little sensible).
Some randomic minor issues with YouTube app (sometimes, after skipping ads in a video, you'll get just a grey screen - close and reopen video to fix the issue)
Some randomic issues with bluetooth MAC address (bluetooth app crashes always). To fix this, you need to get (take note!) the address by going to stock ROM and getting that from Settings > About tablet menu. Then, come back to LineageOS 16 and rewrite the file /efs/bluetooth/bt_addr by using root permissions and a root file explorer, or by using adb push/pull, better in TWRP.
In all millet, camera crashes when trying to take pictures and can't zoom
5 GHz WiFi networks between channels 149 and 161 are invisible to the Tab
In matisse3g and millet3g SIM isn't working

Failed to flash
Hi I am running into an issue flashing your rom in recovery. I have TWRP 3.0 flashed and when I flash your rom I get the following error:
E: unknown command [log]
Updater process ended with ERROR: 7
Error installing zip file /sdcard/lineage-16.0.20200108-UNOFFICIAL-milletwifi.zip
I have redownloaded the rom multiple times to verify that the zip isn't broken. I am flashing it on a SM-T230NU that is rooted as well.

Flash latest TWRP

But your device is neither millet (t33* series) or matisse (t53* series) so it is not compatible

Thanks a lot for the ROM! 1st was trying to get the LightningFastRom running but ended up in a bootloop to recovery with the Lineage 16 versions.
Then got to the Telegram channels and saw there that you opened that thread @xda here and gave it a shot.
After a clean install I am really happy especially because the phone part works!
Not tested Skype yet and Camera is not really the burner anyways
Even so, any idea if there is a working Google Camera Mod available?
One thing I figured out: the tablet does not go to sleep/shuts down the display anymore if I close my cover (magnetic one). Any idea how to solve that?
Again thank you very much!!!

Everytime I try to install it with gapps I get a booloop in T530. I'm flashing ARM 9.0 Nano, is this correct?
Edit: NVM, just took longer to boot. Working flawlessly.

Nice dude!
Wow even though the tablet is old you actually made it happen! My tablet is now pretty useless so i can test this for you Good job dude

Great work first off...
I have reflashed a number of times:
1. os, 2. reboot to recovery, 3. flash gapps, 4a. flash su enabler for lineageOS (was not compiled with ‘export WITH_SU=true’) or 4b. even magisk.
Reboot, setup - enable root for apps/adb via developers tools. Works : but something stops it from going forward and 'sticking' then the app reverts to non-SU state and says Root not available.
I have searched, I have found little on this... any help would be appreciated. If there is an 'easy' way then great but many things are not ever so easy.
Thanks in advance...
*Edit*
It has something to do with more than just the ROM or flashing, on any 7.1.1 it is the same... not sure where to go from here.
SU can be installed and openly visible, even works for seconds and then KNOX? or Some other protection brings it back to unavailable.
**Final Edit**
Sorry everybody, I have not rooted since Gingerbread... I was getting rusty.
All is good, I only needed to mount /system as RW to copy my hosts file into place. I feel a bit silly.
@matteo0026:
Really great work, this tablet is doing GREAT with your ROM and TWRP. Thank you for taking the initiative!
Keep up the Community Love!

Thank you very much for supporting 6 years old devices... Please keep your work.

Has anyone had a problem with the milletlte/tmoT337T or T335 going directly into safemode after installation. It happened to me on LOS 14, 16 and the latest 20200110 build.
Thanks.

how do media apps work on the rom.any issues.also do plan on using the rom on the device as i have no longer bought tablets in a while.most of these devices have been phone as they have better performance then the mid ranged priced tablets.

What do you mean by media apps? Make practical examples, please.
Anyway, I'm going to build and upload new builds with security patches updated to February 2020. So, new builds start from today, 21st February. I can't build and upload all the builds fast because I'm using a medium-range laptop and an ADSL connection at 1 Mbps in upload.

I'm on the last 5.1.1 that TMobile released for that Tab 4. But I'm glad for the response and I'll give the new builds a try. Thank you.

Thanks

matteo0026, thanks for build these roms for tab4 tablet.i have another tablet which devs don't even want to develop for which is stuck on android 7.1.2.at least the tab 4 has multi development love even though both tablets are from the same time frame of 2014. a tab 4 which i got from a family member and plan on using it asa good tablet .wwill you anounce hwen you have new builds here.thanks again. the media apps that i was talking about playing wer netflix, youtube and apps like that . i know that apps like tune in , and i heart radio fm usa will probably work for streaming audio i was jsut asking about video playback. .

any plans to keep teh project going with monthly security updates or maybe think about a lineage 17.1 build to android 10 for the devices.just wondering. i have flashed and kept alot of devices alive through either official or unofficial builds of cm 12-14, to lineage 14.1 to 16.0 from all the way from samsung galaxy s2 to all the way up to nexus 6p and pixel XL. so i dont mind doing the work and learning. .

Don't do 2 messages. We are in a forum, so you have all the time to edit the old post.
Anyway, I don't think Netflix works, as other feedbacks told me (app can't be found on play store because of problems with safetynet I guess), but YouTube yes, of course.

I'll keep this build with security patches. Unfortunately, I haven't a good computer to build them and a good Internet connection to upload them, but I'll try to do all I can do.
Lineage 17.1 is already on the way (look at the LightningFastRom 17.1 by DJabHipHop), but it isn't as stable as lineage 16.0. Another thing is that I have a matissewifi, but I can't use it because the mobo is broken and probably requires a work of microsoldering. So, I can't test personally the builds...

Hi,
I´ve installed this rom on my Tab 4 10.1 wifi a few days ago and I´m really impressed. Thank you for your great work!
The rom is working smooth and stable in general. But there´s a problem with the Xiaomi Home app. I'm using this app to control my Roborock S5. Starting the app works fine. It´s even possible to log in or create a Xiaomi Account etc. But when I try to open the control panel of the Roborock S5, the whole system crashes while the app is downloading the map from the Roborock S5. The system reboots completely without any warning. This happens every time at the same moment. On other devices (Tablets, Phones) the app works without any problems. I had the same issue with another app that´s installed on the Tab 4 but it only happened once. I think, there´s some kind of a bug in the system. Is it possible to find and fix it?
As far as I can tell, everything else (accept the dark rear camera) is working fine.
EDIT: My Roborock S5 got an firmware update yesterday and now the app/Tab 4 doesn´t crash anymore.

heres my question with this one.do you have to format internal storage to decrypt as i dont know if theis device is encrypted. Before wiping and installing rom and gaps.just wondering as i had to do that to another device in order to install the rom an dnot to have twrp pass word screen come up an for the lineage rom to boot to lineage set up screen. jus want the exact steps so tha icna havea correct installation. as i am only going to do this once to this device.

here's my question.with the installation of the rom. do you have to format internal storage an then wipe and install rom and gapps . what is the exact correct process that i need toperform to have a correct installation of the rom.i cant provide development but i can provide testing of your builds.

Encryption isn't supported in my build of TWRP, so don't try to do that with LineageOS.

[ROM][STABLE][R7S/R7Sf][OFFICIAL][9.0] LineageOS 16.0 (Qualcomm)

*reserved*

Please make sure before upgrading to LineageOS 16.0 to read the Official Instructions here in LOS Wiki carefully!
Make sure before flashing you upgrade the TWRP version with the one provided in the instructions page due to changes to support hardware accelerated encryption on our R7S!
You will run into issues if you do not upgrade to the provided TWRP version!
I recommend a clean install due to above changes.

Followed the instruction exactly but wifi does not work (mac address 02:00:00, it can not find any AP...)
If someone has this issue like me, flash back to Spectrum then boot into it and connect to some AP, then flash LineageOS again, but do not wipe anything.

Does Pixel Launcher work for you?
It crashes on my phone. A workaround: https://www[.]reddit[.]com/r/LineageOS/comments/awjvnk/lineageos_16_stock_open_gapps_pixel_launcher/

Working well so far even though I updated using twrp 3.2.3
Only issues are, app permissions seem to show up when they want and bluetooth connection can be ropey depending on device. Have one receiver with no issues but my Sennheisers cant keep a connection from two feet. Will try re-pairing.
Thanks to you all. :highfive:
I needed this for root, so for anyone who needs it...
https://mirrorbits.lineageos.org/su/20190304/addonsu-16.0-arm64-signed.zip
Edit.....Just updated to latest build and root disappears so the above will be needed.
Will the SU binaries be reinstalled for future builds?

I do use magisk, I need to install this beforehand or magisk doesn't work.
When I first installed 16, I read that lineage removed the su binaries so there is no root out of the box.
Bit of a pain really.

When the screen is locked, you're still able to swipe down from the status bar to expand it to show buttons. Is there any way to disable expanding the status bar when the screen is locked?

Just tried the recommended TWRP image and it screwed it up. Now i have no recovery! I'll have to attach to a computer to see if I can reflash it to get back in. Anyone else try this with the same result?

Hi, is there any difference between the build 16-04 and 17-04 ? No changelog is shown.

The recommended TWRP image is actually a lower version than the official image through the TWRP app, and that's why my recovery got screwed up. I'd flashed an earlier image onto a later one. The recommended one would probably be the one to use if you were switching to Lineage for the first time, maybe? Just to warn people not to be as careless as I am!
I spent half a day messing about with getting the tools again to perform a flash from my pc. Every time, I end up relying on "Minimal ADB & Fastboot" because I have no luck getting any other driver package to work. But this package really is the smallest pack to get it done and it makes it easy to use, thank goodness.
Thanks to the developers for continuing to work on the phone. I'm loving Android 9/Lineage 16. There isn't much of a visual change, which is great. Under the hood, it's more obvious, but it's definitely running much smoother than L15 already.

There will, of course, be changes, or it wouldn't be offered. Most changes are bug fixes or security updates, so you wouldn't necessarily notice any change.

Maybe the gestures are sensitive but every time I go out, the phone always opens my music player at destination. Have turned them off see if it happens again.
Never happened on 15.

Bluetooth seems to be a mixed bag so far. When it works it's fine, but when connection is lost re-pairing and forget/connect can be hit and miss. It will show the device but not be connected so you have to go deeper into settings to fix it.
More often I always end up going the long way round just to get connection.
BT ended up rock solid on 15 so I'm confident it'll improve.
Update. So clearing storage and cache in 'App info' seems to have fixed connection issue. Let's see how we get on...

Mine keeps connecting, disconnecting, connecting... But only when there's no music playing, like it's trying to save power (so maybe it's one of the battery saving services under Android 9). Mine isn't forgetting, though. At least not yet...

It's a problem with Pie on the whole apparently.

[ROM][discovery][Pie][9.0] AOSP [Sony Open Devices Project]

Changelog:
20191024
- Fixed MTP crash issue.
20191023
- Sync'd source and fresh rebuild
- Now have a "Gapps included" variant and a "Gappless" variant.
20191004
- Rebuilt kernel
- Fixed camera turning green or crashing
- Fixed general stability.
20191003
- First build, a bit unstable.
- Camera turns green.
- PTP, MTP cause crashes.
- FM Radio does not work.
Notes:
This ROM is very, very, vanilla. It is straight up AOSP. No frills, no mods, no extras. Just pure source.
I personally don't use Gapps anymore, but I did test that the gapps version boots up and connects. That's about all I test with Gapps, though.
I also don't use social media except XDA, so I don't know how well every app works. But if you have issues and have logs, perhaps I can look at them and see what is wrong.
Can I flash back to firmware 50.x.xxxx after flashing this?
Yes, you can. I flashed this and then flashed back to the 50.2 firmware several times while testing. As always, you assume full responsibility for your device, but it worked for me.
Issues/workarounds:
- Video playback from camera. Any camera videos you record work fine, but the built in player can't play them. I downloaded and used VLC app to play them and they work just fine. You can get VLC or other apps from the play store, or here: https://www.f-droid.org/en/packages/org.videolan.vlc/, or if you are using the Gapps included version, you can use Google Photo.
- If you are using the Gapps included variant, the built in Google Camera app does not work. However, using the playstore, I downloaded a number of camera apps, such as Open Camera, and they all worked. I'll try to look into it if I get time.

The only thing i didnt like about aosp is that you cant add features like gravitybox does. And Unfortunatly I need snapchat cause my woman uses it. lol Breaks the safety Net

Couldn't flash gapps? I'll boot into twrp and flash gapps after booting into aosp and nothing? What am I doing wrong... The is will boot and no gapps appear?

I installed AOSP, let it boot, downloaded 64 bit nano opengapps, fastbooted into TWRP, flashed the gapps via adb sideload, and rebooted. It didn't crash or hang up on me. However, I've noticed that it doesn't install the playstore app. I'm very confused. I tried this several times with pico, nano, micro, and mindthegapps.

Thank you for looking into it? but yeah same I'm very confused as well but I believe I have found something that I'm not at all familiar with. I found this link that has someone that has a similar issue with the responder saying they can use "adb pull" command to flash Google factory images so it might be worth looking into?

Whoo-hoo! Praise God! Good traction on Android 10! After some tinkering with XOSD source, I've got a booting version of Android 10 with the new 4.14 kernel! Certainly not a daily driver by any means yet, but I'll keep tinkering. I'll add a few teaser shots as well. :victory:

Hell yeah man. Thank God we still got one developer on the xa2 ultra threads.

So I've messed with aosp a bit and have found a way to help make things easier. I've installed nanodroid which will give you micro g and it's service and more!
https://nanolx.org/nanolx/nanodroid
I haven't been able to figure it out but it has a setup wizard as well which does give you the option to install the official play store. If any one else can't get that to work then perhaps install osm(gapps) with fdroid and install the "fakegapps" xposed module to get signiture spoofing. Hope this helps?

Great work, and good find!
I am currently building this ROM again with built in gapps ... Hopefully, I can have that and an updated version of aosp that is gappless available tomorrow or the next day (so I can test it a bit). I spoke with a few guys on the SODP telegram channel, and they make aosp with gapps built in, so I thought I'd try that to see if that helps you guys who want to use this ROM with gapps.

Good news!
I was able to build AOSP 9 with Gapps built in, and will be posing that once I get it uploaded. (It will take a long time, because I have slow internet.) I'm testing it out on my phone now, everything seems to work here. I will also be posting an update of the gappless version as well.

Thank you so much! I have been waiting for this but when do you think it will be available?

Good news! It is up and posted. Be sure to fully read Post #1, and Post #2 before proceeding.
I tested both the gapps included, and the non-gapps versions on my phone, both worked. With the Gapps version I was able to connect and download several apps, my emails synced, as did photos, etc....
For this rom, the things that I am actively working on are MTP/PTP computer connections.
Also, Android 10 is still in the works, it's just giving me a few fits at the moment, but I will keep working on it. I don't want to release a "half baked" rom, I would like it to be 95%+ functional before putting it up for you to use. Hopefully, that will not take forever. :fingers-crossed:

Love it I did notice the ctsintegrity was false but I fixed it with a magisk module other than that it's great!? I understand from your last post you are working on Android 10 but any idea on when your roms will be updated to 5.0.2 version?

Great news! Praise God! With some great guidance from @MartinX3, and a post by @oshmoun, I was able to apply a patch to the kernel that fixed MTP communications for transferring files to your PC! I have the builds now, and will upload them. My internet is really slow, so it will take a while....

FREQUENTLY ASKED QUESTIONS
(Please read them BEFORE posting anything in the thread!)Q: Whenever I try flashing any lineage-17.1 build, I get the following error in TWRP: Updater process ended with ERROR: 7
A: This error appears whenever you try to flash an Oreo-based rom within a version of TWRP older than 3.3. Simply flash the linked below version 3.3 or higher, reboot back into recovery, and flash the rom zip again.
Q: I am seeing Error 7 when trying to flash a GApps package.
A: This is due to the system partition being too small to fit both the rom and the GApps package. You need to re-partition it with a tool such as the one created by Clamor (linked below). You will only need to do this once.
Q: When will any of the variants receive official builds from LineageOS?
A: There are no plans to submit these builds for official LineageOS support, but it should not matter. What is most important is that these unofficial builds be stable enough for daily usage, which they are, thanks to followmsi's tireless work in porting Android 10 to these venerable old tablets.
Note to Junior Members: It is frowned upon in the XDA community to ask for ETA's on builds, features, bug fixes, or other improvements to the code or its functionality.
Q: Even if neither dev nor flo will ever receive official LineageOS support, just out of curiosity, what are some of the differences be between unofficial and official builds?
A: The following technical changes are in effect:
- Built-in su root will be removed: You will have to download and install the su addon from LineageOS Extras.
- Tablet status > LineageOS updates will be activated, allowing for the OTA downloading of official builds.
- The official builds will be digitally signed by Lineage to prove that they do not contain malicious source code and are able to pass the Play Store's SafetyNet check.
Q: How often will new builds be released?
A: About once a week for both deb and flo, as soon as possible after each new Android security patch level is merged, and of course whenever a new feature is added or a bug is fixed, as per followmsi's advice.

How to flash LineageOS and Open GApps1. Move any files you want to keep to your computer or flash drive via a USB OTG cable – ! Or you will lose them !
2. Download your LineageOS Rom and GApps Package,
3. Boot into Recovery Mode (Hold volume up and Power button until you see TWRP's splash screen),
4. Wipe > Advanced Wipe > Select On (enable tick) for Dalvik / Art Cache, System, Data, Internal Storage, Cache,
5. Swipe to Wipe at Bottom of Screen,
6. Back to Main start screen,
7. Wipe > Format Data,
8. Type 'Yes' and press blue checkmark at the bottom-right corner,
9. Go Back to Main Start Screen,
10. Move your LineageOS Rom and GApps Package to the internal storage,
11. Install > select a zip file to flash (optionally, Add More Zips > select another zip file to flash),
11. After you have finished installing the Rom and GApps > Wipe Cache/Dalvik > Swipe to Wipe,
12. Reboot System! Enjoy!
Typically if you do not do a Clean Install then you are not allowed to report errors or problems. If you Dirty Install and you do have problems then you will be asked to Wipe All and Clean Install and see if the problems still exist. This is a DAILY changing rom and any bug that you found was not working on the previous day's build may be fixed with todays daily build. On a side note, the code implemented to fix that bug could potentially break something that worked on that previous build. So reporting problems on a day old build that you dirty flashed over whichever build of whichever rom you had flashed previously will not be accepted as a true error.
Problems known to happen after a Dirty Installation1. A muddled up mess of a system. You are taking a rom and installing a newer rom with changes over the top of your old rom. Between these two periods of time during which you used your phone and created data, changed system options, and used apps. This is absolutely increasing the risk of causing problems somewhere in the system/data partitions. Some people have luck with Dirty Flashing. However, it's always hit-and-miss because of what we mentioned above about bug fixes breaking previously working functions. Dirty flashing doesn't only create problems if the source code of the system data and the system settings of the new build are significantly different from those of your previous build. That's not to say that Clean Installing won't ever create problems, but only bugs present on a Cleanly Installed rom are relevant for development purposes.
* Clean Install: Fully wiping everything and installing the rom onto a fully clean system/data partition of the phone.
* Dirty Install: Installing the rom and GApps over top of the older rom to save time and not have to reinstall all the user apps and tweaking system and app settings that usually take a lot of time to set up as you like.

I was just curious about GApps for this ROM. Going to the link you provided and just simply going to opengapps.org/ does not show a gapps version for Android 10. Is it ok to use one for Android 9?
EDIT: I was searching around for a GApps package for Android 10 and found this.... https://sourceforge.net/projects/opengapps/files/arm/beta/20190928/
I installed your ROM with the GApps above and it is working great so far. Thank you for the work you put in making this for all of Nexus 7 owners!

Is LineageOS seperated from AospExtended in the other thread?

Lineage-17.1
Like mentioned before .. I did plan to handover Lineage-17.1 beginning of 2020.
That's done now.
@ripee will continue to build regular lineage-17.1 builds for flo/deb.
If there are some code changes in the next time .. we test on AEX first and apply changes to Lineage sources later on.
Thanks to @ripee for taking over !
Cheers

Nice job

I would like to use microG with this ROM. Any chance to include signature spoofing into the ROM? Or do you know of any other method to use microG with this ROM?

I am also curious. My USB port is not functional so I need to always keep one or two OS zip files on internal storage.

1st post tell us that we need a repartition to have enough space to install gapps. During this step /data partition is erased.

It's time to try to fix that USB port !
I've done it twice. The first time I tightened the ground contour with a small pair of pliers. The 2nd time I managed to redo the soldering with a sharp soldering iron.

Hi Everyone
After some months of learning how to build my own Roms and how to edit the proprietary files of this Device i was able to build my first edited version of LineageOS 15.1 with HW Acceleration and the Camera working.
Its a slim an snappy Rom for everyone that´s looking for a monthly updated Android 8.1 Rom to keep this unique Device alive.
This first release is really basic because i deleted everything that doesn't work right.
My plans for this Rom are to keep it updated in case of Security Patches and add some Features here and there as i still learn how this Device and Android is working in general.
Also the official release of LineageOS 16 will end the development of this Rom for the reason i don't want to rival the official contributors of this Device.
Little FAQ to this Rom:
Do i need to Wipe my existing Rom even its LineageOS 15.1 based ?
Yes because i use my own Release Keys for this Rom you need to Wipe your existing one.
Is this Rom compatible with every Shield Tablet ?
Yes this Rom is working with every Shield Tablet
I have a Shield LTE Version and after flashing this Rom i cant connect my device for Data Transfer with my computer anymore.
For some Reason i still didnt found out on LineageOS 15.1 there is no Drop Down Menu for this Device to change the type of connection.
To change it go to Settings > Connected Devices > USB
I found a Bug with this Rom i didnt had on any Rom before what should i do before i post it here ?
Before you post any Bugs and Errors here make sure you installed this Rom correct as i told with a full wipe in your recovery first and if there are modifications installed like Magisk
Moduls or Xposed or you changed this Rom in any way, you should reinstall it fresh first to take a look if the issue still occurs.
If yes post a detailed report of the Error with a Logcat.txt File
Can i install and use Apps like Netflix, Amazon Prime,.. and watch content in HD again with this ROM ?
As this is a Problem with the Widevine Services and this Device itself this Rom doesn´t change anything on that. If you want to use the Netflix App for example you still have to use the liboemdecrypt modul on Magisk and its SD only
Thanks goes to:
@Steel01 and the whole LOS Team for doing all the hard work to keep this Device alive
@Artemka2008 for figuring out the OMX fix
@Triodexe for uploading his work on his Github so i could figure out how to edit the vendor files

Thank You for breathing new life into this great little tablet!

Thanks for keep this device alive!

Any ideas why clash of clans will not work on this ROM? Installed COC from Amazon App Store right after flashing this ROM and the game closes with no error right after it fully loads at the loading screen. Tried Lineage OS 16.0 and had the same exact issue using the google play store version with pico opengapps. I just want to use a smooth running ROM and play clash also QQ. Clash ran like trash on the stock 7.0 rom even after doing everything possible to make the tablet smoother.

Thank you very much and nice job Scavenger for keeping our tablet up and running!

Tried this ROM and was very happy to finally see one above Nougat on my shield tablet k1 that has 1080p 60 FPS videos playing smooth with no artifacts and doesn't crash. Also super smooth. Very nice, congratulations and many thanks.
However after I rebooted to recovery and flashes magisk it got stuck forever on Nvidia logo
Wiped everything again, reinstalled (ROM and gapps) and it booted without magisk. Tried flashing magisk again, same problem
I never had this issue with magisk before on this tablet (and I've tried several ROMs).
Anyone else faced this issue? Any advice?

@ogremalfeitor How do you tried to install Magisk? Refer https://topjohnwu.github.io/Magisk/install.html
What would be the right way to install it?
@Scavenger87 Besides your LOS build we find also a recovery.img at androidfilehost.com - do we have to patch this one with the Magisk app? I never tried the LOS recovery before.

I tried many ways.
Usually with the latest magisk versions I rename the APK to ZIP and install it via TWRP (you can't do that with normal APKs but magisk one is special). This method has worked for me with other ROMs. From then on, when there are Magisk updates, I use the magisk manager app.
Meanwhile I tried dumping the boot partition from TWRP and use the manager to patch it, then flash it via fastboot. Same problem. If I then flash the unmodified boot image back, the system boots fine.
I'm now trying everything again, with the 3.5.0_9-0 version of TWRP (I had 3.4.0 installed). Also I was using aroma opengapps (costumizing what I want), I'm now going to try with pico as said in the first post. Will post back results.

No luck, same problem
Root addon from lineage os works, but fails safety net check pretty badly and does not support modules like Magisk...
@Scavenger87 do you have any advice to get Magisk working with this ROM? Are there any place logs are generated when the tablet is booting on the nvidia logo where mine is getting stuck? Thanks in advance.

Hello,
I have a question.
What should i Do with
Firmware Update : N/Stock 5.0
I have installed the Rom and the Gapps. And IT runs, on My K1

It's just there for people that might have an outdated stock firmware. If it worked for you without it, you don't need it. Someone correct me if I'm wrong

That's not it. The boot.img is unique to every ROM. It contains the kernel and the initial ramdisk (initrd, if you're interested in details search for that and there are a lot of interesting articles explaining the boot process of Linux and derivates like Android).
I know magisk modifies the initrd to sort of "inject" itself during that early boot process, but it doesn't make the system hang with other ROMs, hence before assuming it's a bug in magisk I'd like to know if anyone has any idea or if the ROM is missing anything that could cause this?

I believe it has to do with outdated bootloaders, which will be the case for people who never used recent stock firmwares, and it's there should you have problems (but don't confuse bootloader with boot partition or boot.img that I mentioned in another post). I think the script in the Zip detects it when you flash in twrp and gives an error if necessary but please correct me if I'm wrong.

I have try to installed the Firmware Update : N/Stock 5.0 in TRWP. It doesnt work. A Error Shows and it cant installed.

Well meanwhile I went on and started using this ROM without magisk. Started to have crashes here and there not long after, like most (if not all) ROMs for my tablet above android 7... until the video started to get corrupted in YouTube Vanced too which is a deal breaker for me.
Guess this is not the one ROM to solve my problems with this tablet after all, but still it's a great effort. Hope others enjoy it and thanks to the dev for sharing.

Hi everyone after a little vacation and some testing out of your reported issues this is what i found out so far:

Any ideas why clash of clans will not work on this ROM? Installed COC from Amazon App Store right after flashing this ROM and the game closes with no error right after it fully loads at the loading screen. Tried Lineage OS 16.0 and had the same exact issue using the google play store version with pico opengapps. I just want to use a smooth running ROM and play clash also QQ. Clash ran like trash on the stock 7.0 rom even after doing everything possible to make the tablet smoother.

I installed that game on a Tablet with LOS 14.1 and LOS 15.1 and in both cases the Game crashes because it run out of memory. I did a quick test on my Rom with adding ro.config.low_ram=true to the build.prop which activate the Go Version of Android and decreased the usage of Ram this way .
The Game runs but it started to get really sluggish after around 30 seconds.
It seems this Game just needs more than the 2GB Ram this device can offer.

Tried this ROM and was very happy to finally see one above Nougat on my shield tablet k1 that has 1080p 60 FPS videos playing smooth with no artifacts and doesn't crash. Also super smooth. Very nice, congratulations and many thanks.
However after I rebooted to recovery and flashes magisk it got stuck forever on Nvidia logo
Wiped everything again, reinstalled (ROM and gapps) and it booted without magisk. Tried flashing magisk again, same problem
I never had this issue with magisk before on this tablet (and I've tried several ROMs).
Anyone else faced this issue? Any advice?

After trying to flash many Versions of Magisk starting by 21.4 over 22.0 and the actual 23.0 via the TWRP Recovery Version (9.5.0_9-0) i mentioned in the Start Thread and trying to flash it with the Magisk App i also wasnt able to install Sucessfully Magisk without running into a Bootlop which is really a Bummer.
I dont know why this happends and i check my Kernel Logs i pulled with TWRP but for the moment we have to use the SU Addon by LOS.
Maybe it has something to do with that my build is signed with a personal key i will check that out.

Thats just the Blob File that needs to be flashed when the Bootloader isnt updated to the latest Version (4.00.2016.04)

On some rare ocassions you get those same green artefacts on videos like you get with the LOS 16.0 Rom but at least in my case it happends once a week or so and it seems it have something to do with memory managment again.
My guess is that the tegra drivers arent working really well with Android Versions above Nougat (7.0) and this leads to a memory leak but like i said its just a guess by me maybe @Steel01 can say more about that.
I try to optimize the memory management in the future builds if possible.

Hi Everybody
I think its time to give you a little update of my work on this build
After i got a good example of the problems with the ram management of this device i was looking for a solution last few days and i began testing with the Android Go Settings as i mentioned in the last Thread.
With that settings i was able to start that Game mentioned by @Hworangg and i even was able to play it a bit as you can see on one of the added Screenshots below. But you could also see this Game is a real RAM Hog with needing up to 484MB at the last session i played but it is kinda playable you just have to stay in that Game and turn off every notification as it might crashes otherwise. Speaking of crashes while the GO Settings really helping on reduce the usage of Ram by the System itself and let the device take more Memory Pressure it also leads to freezes where you often have to Hard Reset the Tablet because it seems to not close the Main App when its in a Out of Memory Situation. This is something i have to invest more time and research even after i played a lot with the Dalvik VM Settings.
I also found out that my Personal Key Signature is the reason that the install of Magisk is leading to a Bootloop. Here i also have to figure out why this is happen and if its even possible to install Magisk on a Signed Custom Rom as you change out the BOOT.img on this Device to achieve that and it seems the Magisk installer isnt able to resign the File with my Key.
TLDR:
I was able to set up my Build to use the optimized Android GO Settings to withstand more Memory Pressure so that Games like COC and heavy Browsing Sessions with lots of Tabs and Sites with a lot of Pictures doesn't crash that soon but it lead in both cases to a freeze of the whole Device.
The Magisk installer does not work when i sign my build with my own key.
For this Reason i decided to release a another Build for you to test with this Settings as a Nightly Release before i release my next Regular Build when the next Security Patch is out
You find it here : Nightly Build and i´m curious about your opinion.

Flashed the nightly onto a freshly wiped K1 along with opengapps and Magisk 23 using patched boot, no problems there. Video playback - Netflix played about as well as it could with level 3 widevine, with Jellyfin no obvious visual problems streaming 1080p over lan. Got hard freezes when running memory heavy apps (firefox, manga reader, 3d unity games) but it was expected.
Ended up downgrading back to factory stock Lollipop as the memory management is best there, even better than stock Nougat. But will keep an eye on your builds because the K1 could still be a great little tablet if the memory issues in newer versions of Android was fixed. Thank you for your hard work

LineageOS is a free, community built, aftermarket firmware distribution of Android 11, which is designed to increase performance and reliability over stock Android for your device.
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. You can also view the Changelog for a full list of changes & features.
Installation instructions :
Be sure to have installed latest TWRP recovery (you can find it in downloads) and latest Android Lollipop (5.0.2 for matisse, 5.1.1 for millet) firmware
Download the latest build and GApps (ARM) - if you'll go to wipe even internal storage, put them on a microSD or an USB OTG, or copy them after wiping it
Boot to recovery mode
Wipe > Advanced wipe > Select system, data, cache and dalvik/art cache (and, if you want to clean more, select even internal storage, which deletes all the content in /sdcard) and do swipe to wipe. When it finishes, go to home page
Install > select ROM zip file > swipe to flash and, when it finished, go to home page
Do the same thing to flash GApps
Reboot > System
Update instructions :
Be sure to have installed latest TWRP build
Download the latest build
Boot to recovery mode
Install > select ROM zip file > swipe to flash and, when it finished, go to home page
Reboot > System
Known issues :
Some randomic minor issues with YouTube app (sometimes, after skipping ads in a video, you'll get just a grey screen - close and reopen video to fix the issue)
Some randomic issues with bluetooth MAC address (bluetooth app crashes always). To fix this, you need to get (take note!) the address by going to stock ROM and getting that from Settings > About tablet menu. Then, come back to LineageOS 18.1 and rewrite the file /efs/bluetooth/bt_addr by using root permissions and a root file explorer, or by using adb push/pull, better in TWRP.
5 GHz WiFi networks between channels 149 and 161 are invisible to the Tab

Thank you for the rom I got this running today. Working well haven't seen anything really out of the ordinary.
Dpi on this tablet is meh haha.
My experience was smooth up until I had to install gapps. Had an error with system partition mount.
Ended up loading into LOS without gapps. It installed LOS recovery then loaded balls from there.
The performance isn't really as snappy but it's an older tablet. Can I expect more? Or improve it?

Hi, I'm using stock DPI, but if you want, you can change the screen elements or font size in display settings.
About gapps, you can even try BitGapps or beta opengapps.
Performance-wise, probably this is almost the limit. I'm working on getting faster booting times, but it isn't that easy. While in usage, probably with some kernel tweaks and overclock, it can go better, but I'm not able to do these works in kernel.

This is really awesome. Thank you for the efforts and taking your time to provide this to the community. I literally just pulled my Tab 4 out of my old locker and gave it a charge. Coming to see it has lineage 18.1 available to it, really blew my mind. Fantastic!

Awesome! Is there any chance to run this on SM-T230 degaswifi (7.0) devices?

No, sorry, or, no from me. Tab 4 7.0 have different SoC. I'm just working for Tab 4 with msm8226 (snapdragon 400).

Bummer... thanks for the quick reply!

Just to let you know, now advanced reboot menu has been moved from developer settings to gestures menu. Wow, and I'm not the one that found it. Thanks @crazydrive22 .

Which apps come with MindTheGapps Android 11? Is there any bigger versions or add-ons?

If I'm not wrong, it's just a small package with the essential apps, like play store and play services. You can look at Bitgapps too.

Which OpenGapps package is MindTheGapps comparable to? What's an easy way to install BitGapps + full addon package?

Ah I forgot, there are Opengapps too, but they are a beta version. Mindthegapps package should equal to a pico Opengapps package. By the way, I'm not an expert about GApps, so I can't tell you anything else (regarding Bitgapps too).

have used the open gapps 11 test package. it works and then you grab the rest of the apps that you need from playstore.

Dear Matteo,
thx for the awesome ROM. You did a great job.
I am facing one issue with WiFi.
I am using a hidden WiFi at home and ROM is able to connect to it when WiFi is setup.
But it will not connect ot the WiFi when WLAN switched on. I have to delete current network and re-configure ot to get access to my network.
Network is declared as hidden during setup.
Do you know this issue or is anyone else having the same prob?
Do I need to set it ip differently?
Thx, mate, and all the best.

I just pulled out my Tab4 8" and got this working very easily.
Oden 3.14.1 to upgrade to TWRP 3.5.2, then transferred Lineage 18.1 milletwifi & open gapps arm 11 pico to the device via USB and installed. Very pleased with the performance thus far. It's running better than Lineage 16.
Thank you to all who had a hand in bringing this together.

You can also use Nikgapps for LOS 18.1. The core package would be comparable to Gapps pico.
NikGApps - Custom Google Apps Package!

@matteo0026 Thanks for LOS 18.1. As 17 seems stable, I'll be stick with that for now on my SM-T530NU.

Hi, unfortunately, I've never tried to do these tests. Try to do some other tests by setting IP differently, as you told, or some other ways you can think to fix the issue, if it's at your side and not in the ROM side. By the way, I'm really surprised for what users want to use this tablet at this time yet, by looking LineageOS 17.1 too. And I guess something won't be fixable. Blobs are old, and tablet can't support everything perfectly

As others have already reported, the MindTheGapps-11.0.0-arm-20210412_124103.zip file apparantly can’t be installed with TWRP (mount error). I installed the open_gapps-arm-11.0-pico-20210130-TEST.zip instead.
https://sourceforge.net/projects/opengapps/files/arm/test/20210130/
Today I made a new installation and installed the BiTGApps-arm-11.0.0-R28_signed.zip with TWRP (22 MB smaller than open_gapps-arm-11.0-pico-20210130-TEST.zip).
https://www.pling.com/p/1462973/
As already reported in the thread on version 17.1, the automatic detection and switching to a connected USB DAC does not work with my SM-T530 and the DAC’s GGMM A1 and SABRENT even with version 18.1. With 17.1 you could manually switch the audio output to USB DAC and back to internal speakers using the LesserAudioSwitch app. With 18.1 (Android 11) the app no longer works, if you install it normally. Android 11 requires a permission for audio routing. Here my solution, if you have root by Magisk. Download the "LesserAudioSwitch.zip" file from here:
https://androidfilehost.com/?a=show&w=files&flid=319752
After extraction the ZIP file you get the "Lesser AudioSwitch 2.6.0.apk" (free, but 2 Options locked) and a "privapp_lesser.xml file". Copy the "Lesser AudioSwitch 2.6.0.apk" (set the permissions to "rw-r--r--") via Root Explorer into the folder "/system/priv-app/" in a new subfolder "LesserAudioSwitch" (set the permissions to "rwxr-xr-x") and the file "privapp_lesser.xml" file into the folder "/system/etc/permissions/" (set the permissions to "rw-r--r--"). Then you have to restart the device and "Lesser AudioSwitch 2.6.0.apk" will automatically installed as system app.
Go to "Settings/Apps & Notifications/Show all (xx) apps/Lesser AudioSwitch/Storage and cache/", then "Wipe cache" and "Wipe storage" and "OK". Click onto "Back"-Button, "Force quit" and "Deactivate".
Download this modified version "Lesser AudioSwitch 2.5.0" (both options unlocked) from here:
https://www.happymod.com/lesser-aud...r-audioswitch-mod-apk-v2-5-0-downloading.html
Go to "/system/priv-app/LesserAudioSwitch" and delete via "Root Explorer" the "LesserAudioSwitch2.6.0.apk" file and copy the "Lesser AudioSwitch 2.5.0 mod.apk" (set the permissions to "rw-r--r--") into this folder. Restart your device again. The "Lesser AudioSwitch 2.5.0 mod.apk" file will automatically installed as system app. Go to "Settings/Apps & Notifications/Show all (xx) apps/Lesser AudioSwitch/" and tip on "Activate".
Now the app works like with android 10 and with both free options "RESTORE ON BOOT" and "AUTO". You may have to reinstall the app after an update of LineageOS. Important: Don’t enable "MagiskHide" for this app in the "Settings" of "Magisk" (click onto "shield" symbol, "MagiskHide", "Show system apps" and "Show all installed apps", only enable: "Google Play Store" and "Google Play Services")!
Go to "Quick start window", click onto "pencil" symbol for editing, drag the icons "USB DAC", "Speakers", "Headphones" and "Bluetooth" into the "Quick start window" for faster change of the audio output.
Good luck installing!
@matteo0026: Thank you for LinageOS 18.1 on a 7 year old SM-T530!
Great job!
Greetings from Axel!
