The build from 2022-12 isn't the latest build. You can find the latest builds on this page:https://github.com/matteo0026/OTA/releases Download the correct one for your model.

Note that the latest builds have OTA support, which means that when an update is released you will get the update which eliminates the need of flashing the newer build manually. fFlashing any build newer or equal to 2023-1 build it will have OTA support. Any build older than the 2023-1 build won't have OTA support.
[Galaxy Tab 4 Original Android Development] CENTCI:
Thanks @TheGamerKing for the reply, I actually tried almost all version and they are working fine, but my only problem is until now my device has no network, I have search everywhere for solution and there seems nobody has ever fix this, but @matteo0026 told me that the above build is where he tested the OS and it work but for me I tried from every build in a row n in don't have network, unless am not doing something right am more than confuse.

I would appreciate any kind of help, video or some sort of blog guide links.

Thanks

Hi, someone tried mattisewifi or milletwifi in a degaswifi device? They are incompatible?
[Galaxy Tab 4 Original Android Development] Sebiches1:
@matteo0026 In the latest updates the governor remains in performance, I feel that the battery has seriously decreased due to this. Switching between power saving, balanced or performance does not work. :( Would there be any solution? (By the way, I thank you for the work you have done for this forgotten device. My father has had it for a long time and recently his favorite apps do not work on the Android version. Fortunately I found your roms to give new life to his beloved device. thank you)
[Galaxy Tab 4 Original Android Development] matteo0026:
They are completely incompatible. Trying would result in a non flashing or non booting device.

I just forgot to look into that thing. I hope to have some time to look at it as soon as possible.
[Galaxy Tab 4 Original Android Development] nmargono:
Not sure if it was discussed on here already, but I rooted the SM-T530NU via CF-Auto-Root, and after flashing @matteo0026's LineageOS16, the device becomes unrooted (??). I tried flashing CF-Auto-Root via Odin again after that, and it stays unrooted...

Any clue?
[Galaxy Tab 4 Original Android Development] J.Michael:
Does @matteo0026's ROM include recovery?

I would expect you to "lose root" when you install a new ROM. I've never used CF-Auto-Root, but I found a note saying it installs in recovery. So if the new ROM wrote a new recovery, then it overwrote the CF-Auto-Root.

I don't find any references to CF-Auto-Root or "chainfire root" in this thread. I do see a mention of rooting with Magisk.
[Galaxy Tab 4 Original Android Development] nmargono:
Valid point, thanks for pointing that out, I'm new. I thought these steps are mutually exclusive (rooting vs. flashing custom ROM). I found CF-Auto-Root for SM-T530NU here. Will look into Magisk...
[Galaxy Tab 4 Original Android Development] Zeinfinity:
Thanks a lot for all your hard work, it's working well for now, even if the android configuration process was a bit buggy at the first launch.

I have smt531 lineage 16.0 2020 bulid is there 2023 build and is there diff between performance
[Galaxy Tab 4 Original Android Development] J.Michael:
The "Similar Threads" listed under here shoved a link for a newer version in my face: Lineage OS 18.1

Maybe you'll find something useful in that thread.
[Galaxy Tab 4 Original Android Development] tonyrogers11:
Is latest os lineage 16 work on smt531 and why games crash
[Galaxy Tab 4 Original Android Development] J.Michael:
Have you searched this thread?

Lots of references to T531, clearly something worked well enough for someone's complaint to be that "network doesn't work". No idea whether what I read qualifies as what you mean by "latest OS".

I found a post by @matteo0026 where he says you need "Lollipop firmware". I'm not sure what that means, but it's a place for you to start reading.
[Galaxy Tab 4 Original Android Development] djhooker:
Lollipop Firmware - I think he means the latest Stock ROM based on Android 5.x ("Lollipop"), doesn't he?
[Galaxy Tab 4 Original Android Development] mrk2815:
question since i have not owned the tablet from day one, i got it from a family member, does the tablet not turn off when charging.i notice when i charge the tablet and i turn it off to charge it will turn back on to charge.how come that is the case.
[Galaxy Tab 4 Original Android Development] matteo0026:
It'll be fixed in the next release, with April security patches. Hold on!
[Galaxy Tab 4 Original Android Development] mrk2815:
thanks , i like your rom.i am sticking with it.i will patiently wait for your fixes and april security.thanks a big two thumbs up.
[Galaxy Tab 4 Original Android Development] Oxyn23:
Guys, thanks for the ROM !

So far, it works pretty good on my SM-T335, sometimes an app-crash here and there, but nothing critical. Even Netflix works, but you have to download it as .apk and install it manually.

My big problem: After flashing to your ROM (16.0 20200311, fresh install) , the tablet can't find the SIM anymore. Do you/anyone know how to fix that ?

Best wishes, Phil
[Galaxy Tab 4 Original Android Development] matteo0026:
Send a logcat, please!

Anyway, about offline charging, make sure you are using good quality cables and chargers, since the device should go offline charging just with good quality stuff. If it doesn't fix by changing charger/cable, I should go to solve this problem, but it isn't an easy thing... s3 neo devs worked on it for a lot of time.
[Galaxy Tab 4 Original Android Development] mrk2815:
off line charging does work on sm 330 NU tablet 8.0 .
[Galaxy Tab 4 Original Android Development] y0.o!:
Any eta on getting root to work with this ROM?

I miss root lol

Everything works well atm on my T-350.

What ROM does have root for this device? I've just got one of these tablets and first thing I thought of was lineage os lol
[Galaxy Tab 4 Original Android Development] mrk2815:
there is another rom for these tablets its lineage 17.1 lightning and that one does have magisk root for it. If you want to root. take a look at that thread.i don't know how stable that rom is compared ot his one .but this one is very stable , have ben running it for a month now and no issues what so ever that i can see, except for the fact that the charging turns on the tablet when the tablet is turned off to a power off state. The developer said it would be fixed in the next update with april security updates.
[Galaxy Tab 4 Original Android Development] 0BrokenBone0:
MS Teams

Hi, the ROM works great on my SM-T530. Thank you very much. The only thing that doesn't seem to work is a videocall in MS Teams. In any other app, even within MS Teams, the camera works fine, but in a videocall it just won't enable/start/open. Please help.
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi, can you send a logcat of the problem? I should see what isn't working properly.
[Galaxy Tab 4 Original Android Development] 0BrokenBone0:
I will create one later today and send It to you. Thanks.
[Galaxy Tab 4 Original Android Development] Asher Lee:
hey umm my device t531 is having issues with boot-loop how to fix it? I already have the latest twrp installed every time I installed gapps pie micro
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi, try to flash latest stock firmware and reinstall twrp, lineage and gapps. About gapps, I advice you to install pico ones and after go to install manually the apps you want.
[Galaxy Tab 4 Original Android Development] Asher Lee:
Thank you it now works!
[Galaxy Tab 4 Original Android Development] srk707:
Tried installing got Bootloop SM-T337T. I started with lastest firmware, flashed recovery, Build(Tried both builds) then GAPPS
[Galaxy Tab 4 Original Android Development] cloudx720:
This rom works wonderfully on my SM-T330 thank you.
[Galaxy Tab 4 Original Android Development] Ramar77:
SM T330

error search for MD5 file
[Galaxy Tab 4 Original Android Development] matteo0026:
Download another time the ROM, I didn't publish MD5 file. And please, report with your device, not just by talking ''generical''...
[Galaxy Tab 4 Original Android Development] Ramar77:
SM T330

Hello, thanks for the answer.

I downloaded the file from link

but get the message that he can not find an MD5 file
[Galaxy Tab 4 Original Android Development] matteo0026:
Other users report that it works well. So, re-download the package. I could guess that you got that message from TWRP... So, it's because the package isn't integer.
[Galaxy Tab 4 Original Android Development] Ramar77:
it is a zip file and the following files are included

install folder

META-INF folder

system folder

boot.img

system.new.dat.br

system.patch.dat

system.transfer.list
[Galaxy Tab 4 Original Android Development] matteo0026:
Yes all the files and folders of the zip file are present, but this doesn't mean that are integer... Trust me, re-download it, I don't want to argue anymore for an issue that's not mine, or ROM related...
[Galaxy Tab 4 Original Android Development] Ramar77:
I don't want to insult her

but I can only click and download the file.

downloaded the file again 411 MB
[Galaxy Tab 4 Original Android Development] mrk2815:
will there be a new build for april or may .
[Galaxy Tab 4 Original Android Development] matteo0026:
I'm making builds with april security patches. They'll be online from today, but probably millet devices will be online tomorrow. I always begin with matisse devices.
[Galaxy Tab 4 Original Android Development] mrk2815:
thanks very much.i thought when people were having issues with your downloads or installs of your rom they wer talking about an update to your rom. will patiently wait as you do the bet with keeping an old device up to date with security patchs. thanks for doing that .
[Galaxy Tab 4 Original Android Development] mrk2815:
jus saw the update on android file host downloading as we speak on to samsung sm330nu. has the charging been fixed with the device being turned off to charge. if so then will test.
[Galaxy Tab 4 Original Android Development] 2burnsolamae:
Thank you for the amazing work on the dead tablet brother.. Is anyone else having trouble with the micro SD card.. I tried to format it to internal no luck some errors?
[Galaxy Tab 4 Original Android Development] matteo0026:
Don't do it... Tablet slows down a lot... So, just use original memory as internal.

Anyway, new builds with april 2020 security patches are online. This month, I fixed one sepolicy denial. Next month, security kernel updates and maybe something else... I don't know!
[Galaxy Tab 4 Original Android Development] mrk2815:
will you bring up a 17.1 for the tablets or will you just focus on just giving security updates to the tablets for 16.0 of lineage.
[Galaxy Tab 4 Original Android Development] matteo0026:
Actually, I'll focus on 16 because DJabHipHop is working on LightningFastRom 17.1, which is based on Lineage 17.1. And I can't maintain 2 ROMs because in my PC I have enough storage just for 1 ROM source.
[Galaxy Tab 4 Original Android Development] Liebesrind:
Thanks for the great work. For all having problems installing, try "do not install" twrp app before first boot, that often helped me with other devices.
[Galaxy Tab 4 Original Android Development] mrk2815:
thats fine. no problem as long as there are two maintainers for the tablets that is all that matters.thanks for developing .
[Galaxy Tab 4 Original Android Development] matteo0026:
As someone of you requested me to upload the .md5sum of the ROM, then I uploaded it.

The .md5sum file is a checksum to check if you have some integrity problems with the main file of the ROM. Just put it in the same folder of the main file and TWRP checks automatically if the ROM is integer.
[Galaxy Tab 4 Original Android Development] alexda2323:
a doubt is normal that being the screen turns off drain in 1 hour from 100 to 94 the battery? thanks
[Galaxy Tab 4 Original Android Development] mrk2815:
since its light on resources .thats why you will get less battery drain.i can get about a good day an a half of battery life on the device with lineage 16.0. thats running media apps all day and night long with a few other apps for browsing the net. that's all that the tablet is used for lately but thats good that the developer has kept alive with security updates. unlike hte original OEm whihc has not done much for the device.
[Galaxy Tab 4 Original Android Development] DdragonPT:
Installed the ROM today on my SM-T330, it is working great so far, except for the issues that I have seen reported already. Camera viewfinder is dark, and the fact that if the tablet is connected to power that I am unable to keep it turned off.

Other issues that I had were recovery related when trying to install the TWRP version of files that are in the original post, but found a solution given by a user in the respective XDA forum thread.

Thank you for the hard work. Stable ROMs with recent Android versions are hard to come by.
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi guys, I started rolling out new builds of lineage 16 with may security patches.

Changelog:

- Fixed audio recording via Recorder app

- Fixed lockscreen becoming unresponsive and blurrish after some time

Thanks to [MENTION=10682637]0BrokenBone0[/MENTION] to provide me the fixes for these 2 issues. He's helping me a lot by debugging and fixing stuff. :)

- Embedded lighter bootanimation for smoother and faster bootings

- Little cleanup of sources

- Added an option to make more fluid experience (disable alpha compositing in Window Manager)

- Merged some kernel security patches
[Galaxy Tab 4 Original Android Development] frangiaco:
Hi there! I'm triying to figure out how to update my Samsung 330nu tablet with android 5.1.1 to a new version (I would like a very stable rom 6.x or superior). I don't know how to install anything so if anyone could gift me with some knowledge I'll aprecciate it.

Sorry for my bad english, I'm argentinian :D

Thank you all!
[Galaxy Tab 4 Original Android Development] 0BrokenBone0:
Just search for "custom rom Samsung SM-T330NU". You get sites like this:

androidmtk.com

So steps:

1. ODIN

2. CF or TWRP (recovery-twrp-recovery-matisse-millet)(do twrp because it's still supported by XDA Devs, but both will work).

3. Custom rom

Look at the Rom 17.1 (android 10) of DJABHipHop:

androidfilehost.com

* Note. After installing twrp, first do a backup of your original version rom!
[Galaxy Tab 4 Original Android Development] DdragonPT:
If I may ask, if I currently have installed and running the April version, can I just flash the new May zip file, over the current one, in the TWRP recovery?

Anyway, thank you so much for the hard work on this.

Is fixing the front camera in your plans? It is incredibly useful for video calls.

Cheers
[Galaxy Tab 4 Original Android Development] 0BrokenBone0:
The steps for a new rom are always the same, there is no "update to next version". It's recommended to do a clean flash (install) without your current data. So format first. If you search on these steps you get websites like this:

https://www.theandroidsoul.com/how-to-install-a-custom-rom-using-twrp-recovery/amp/

If you still want to do a "dirty flash" (without formatting), just install the new rom.zip and reboot. But there is no guarentee it works or isn't buggy. It may depend on the version you are coming from and going to, if it's a minor or major version, type of fixes, could be anything actually.

About the camera, front and back, there is no final fix yet, but Matteo is still looking into finding one.
[Galaxy Tab 4 Original Android Development] mrk2815:
never mind about the may 2020 build, as i saw that there are new builds as i was reading through the past few posts.
[Galaxy Tab 4 Original Android Development] donj001:
I really appreciate the effort put into this project. i admit that I have had nothing but problems since this project began. Using milletltetmo but no matter how many times I set back to 5.1.1 stock, (last version) and start fresh flash of TWRP and this ROM, in all variants, all I get is bootloops.

Thanks again for the ROMs, I can just keep trying.

Is there a way to get the tabletUI of android?

Like in settings to have the tablet ui instead of the phone ui?
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi, unfortunately, no. This comes out from build environment. Just apps like gmail use the large screen to improve the user experience (list of emails at the left and opened email at the right). Even telegram has the list of chats at the left and opened chat at the right as in the desktop versions. Probably there should be some other apps, which I don't remember.

---------- Post added at 01:48 PM ---------- Previous post was at 01:47 PM ----------

so should i wait to flash the next build to se what happens with netflix.what i do with net flix is side load .
[Galaxy Tab 4 Original Android Development] matteo0026:
I'm working on it, but still doesn't work. About offline charging, I think we are making progress.

Now tablet stays in offline charging, but not by showing charging status. It stays in this situation. I'll link a photo (as always, thanks to [MENTION=10682637]0BrokenBone0[/MENTION] ).

So, tablet doesn't turn on when it charges offline, but it stays with display on and doesn't show percentage.View attachment 5034977

Microphone dead. Hardware or OS?

With this build I have no sound recorded by the microphone. Completely dead.

Tested with google voice match, and some apps from the play store like voice reocrder. Some apps mentioned that the mic is in use, or I should disable the energy saver for voice recorder. Even "OK Google" doesn't work.

Anyhow, already changed the USB+Mic cable to exlude potential hardware errors, but no better result.

Has anyone else the same issue?

Don't know if the mic has worked before, because I got this Tab broken and built directly up with a new rom.

Model: T530, GApps nano
[Galaxy Tab 4 Original Android Development] matteo0026:
New update with 2020-06 patches is coming out! (It will come out in next days for all the variants, for now just matissewifi)

Changelog:

- Switch to LineageOS msm8226 kernel (with Wi-Fi driver source updated)

- Commonized init (it doesn't change anything to the final user, it's just a way to get more ordered sources)

- Init: update build fingerprints (in this way, Netflix can be finally installed and be found on Play Store, expecially in millet devices where there was a dummy build fingerprint)

Things that still have to be fixed can't be fixed easily. I'll probably buy a motherboard for my dead T530 and I'll restart working faster and better.

Thanks so much.

I was with dirty unicorns since 2016 and I couldn't be happier that you build a new rom based on Android 9.

Initially I had a low wifi performance, afterwards rebooted once and it was fine. SMt335 is fast, LTE is working and the best, even Netflix does work.

No need for any new tablet, my Tab4 is alive again;)

Great work!!!

I will buy you some more coffee, hoping you keep working on that;)
