Don't think I had the option in earlier versions. Anyways, got the august version now, wiped all data. Only installed lineage OS, and it worked!

Just sideloaded gApps and it still works!
[Galaxy Tab 4 Original Android Development] mma151:
Same here

The sim card didn't work in the latest version also

in twrp when I was updating I saw something about matissewifi but I download and flash matisse3g
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi guys, new builds are up.

Changelog:

- September 2022 security patches

- Reintroduced special HID drivers (in this way, for example bluetooth keyboards are working fine)

About the SIM, you should try the build where I said that I've fixed it to see if it works there.
[Galaxy Tab 4 Original Android Development] wekwekwek:
Hello! Can you please help me how to come in TWRP menu?

Button HOME + POWER + Volume UP takes me to some other menu (
[Galaxy Tab 4 Original Android Development] matteo0026:
That's the right way to go in twrp. Otherwise, with a terminal emulator, type reboot recovery and you'll go there. This method works for all the versions of Android
[Galaxy Tab 4 Original Android Development] wekwekwek:
Im noob)) Where is terminal emulator?
[Galaxy Tab 4 Original Android Development] matteo0026:
It's an app on play store.
[Galaxy Tab 4 Original Android Development] wekwekwek:
This is not TWRP
[Galaxy Tab 4 Original Android Development] matteo0026:
Alright, that's the lineage recovery. So... in the initial setup of the tab, you've ticked the option "update lineage recovery alongside system". That means when you flash a lineage update in twrp, lineage recovery is installed and at the next reboot in recovery, you'll find it. To get back the twrp, flash it in odin.
[Galaxy Tab 4 Original Android Development] wekwekwek:
Ok thanks. Working...

Can you help me with one more thing or tell me where to look.

When I upload native firmware for example T531XXS1BRH1 | 5.0.2 | 08/03/2018 | 9827863 | Through TWRP it writes an error

"invalid zip file format! error install zip file sdcard и т.д"

what is wrong?
[Galaxy Tab 4 Original Android Development] matteo0026:
The build could be corrupted. Try to download it another time
[Galaxy Tab 4 Original Android Development] wekwekwek:
How can I fix the problem with the SIM card? Writes that she is not, but she is in fact
[Galaxy Tab 4 Original Android Development] matteo0026:
I've told in the post of september 2022 release:

About the SIM, you should try the build where I said that I've fixed it to see if it works there.

Greetings,

I created an account just so I could personally thank you Mr. matteo0026. I wanted to thank you for all your hard work for the Samsung Galaxy Tab 4 8" MilletWifi specifically. I last used my tablet probably back in 2016 which had the JazzROM 5.11 installed. Beautiful rom but at the time, it was already outdated. I then searched in the forums for any updated roms... not many available at that time. There was Unicorns 6.0 which was also nice but super buggy.

So, my tablet collected dust since 2016. Only recently I decided to venture into it again. Battery was completely dead, recharged it and turned it on. All good. Then I searched the XDA forums again and finally ended up in this thread. Did some searching for TWRP 3.6.2-millietwifi and of course, all links shown were dead. I didn't want to create a Telegram account as I do not like nor have any social media but I ended up creating one (Telegram) just to download TWRP 3.6.2. Thanks again matteo0026 =)

Now it should be said that I had TWRP 2.8.x.x installed and recalled having major issues trying to flash CWM/LOS or other roms to the point I ended up bricking my tablet. I rescued it with ADB, Odin and stock rom after many, many hours of freaking out!!

So that being said, I was apprehensive in trying to flash anything again. One thing to note, having rescued my tablet, I still would get the error "Kernel is not Seandroid Enforcing" during bootup but yet it would still boot and work with JazzRom 5.11. So, I took the risk and flashed TWRP 3.6.2 milletwifi and it worked no errors. Rebooted and the friggin errors was G0nE!!!

I then flashed the Lineage OS 18.1 milletwifi rom and opengapps for arm and voila!! My tablet is revived like Johnny 5 =)

I am very grateful and would like to thank all of you who contribute and participate in these projects.

[Galaxy Tab 4 Original Android Development] The Persuaders:
Good morning. I have the Samsung Galaxy tab 4.10.1 which runs 18.1-20220913 matisselte. I upload my own lock screen and home wallpapers. The dimensions are 1280 x 800 x 149 ppi. I point out that the files are not correctly displayed, while they were displayed correctly and perfectly with the Samsung stock rom. Even with the release prior to 18.1-20220913 there was the same defect, unless I do something wrong. Thank you for the hospitality and attention.
[Galaxy Tab 4 Original Android Development] orb1t:
Hi, I flashed lineage-18.1-20220913-UNOFFICIAL-matissewifi and open_gapps-arm-11.0-pico-20220215 with twrp after wiping everything accordingly on my SM-T530.

After the System reboot from TWRP I seem to be stuck in the bootscreen, I'm new to this device, any tips on fixing that issue? Thank you
[Galaxy Tab 4 Original Android Development] orb1t:
I just found out I think my problem is that I didn't install the latest firmware 5.0.2, is there a tutorial or something for that anywhere including the files? I didn't find it so far.
[Galaxy Tab 4 Original Android Development] Tres_Tigers:
You're asking for a way to go back to Stock 5.0.2?

Are you able to get into TWRP?

If so, did you make a backup of the Stock ROM before deleting it and flashing Lineage OS?

If not, I can (later) upload and send you a backup of my Stock ROM (if your tablet is the 10.1", which I believe it is based on the model and version you installed).
[Galaxy Tab 4 Original Android Development] Timtee [CVHN]:
Kinda curious, any other file hosting sites you could possibly use? (Because I genuinely personally would rather not have to deal with telegram because it simply just attempts to get me to use the app from the direct link, and also I don't really wanna deal with using it via the web browser version as I also would need to make an account that I'd only use like once or twice lol.)

Asking mostly since I decided to mess around with my tablet a bit again for the fun of it.
[Galaxy Tab 4 Original Android Development] duszeks:
Thank you, it's something that I needed in order to run apps requiring a more modern OS like Microsoft Outlook, but I have a one problem - it's laggy. Does anyone else have this problem or have I done something wrong when installing Lineage?
[Galaxy Tab 4 Original Android Development] SteinbeckFan:
Most likely what you have is 8 year old hardware designed 10 years ago, running a modern OS that the hardware was never designed for. Depending on what you do you'll either not notice any performance hit, or you'll find some applications totally unusable. It is what it is.
[Galaxy Tab 4 Original Android Development] duszeks:
Well, I'm probably going to downvote to Lineage 16 then. I didn't expect crazy performance, just something that's perfectly usable for my purposes.
[Galaxy Tab 4 Original Android Development] matteo0026:
I don't have any other mirrors to use. So, we have to wait that AFH comes back to work
[Galaxy Tab 4 Original Android Development] Aramir_:
Stock rom is not flashed through TWRP. You need to unzip it and flash by Odin on PC.
[Galaxy Tab 4 Original Android Development] Farmicist:
Thank you @matteo0026 for saving my 8 year old tablet!

When it was on stock ROM, it would crash whenever I did anything and apps left and right could not be updated.

But now with LineageOS, it's actually usable (albeit still kinda laggy) and apps are updated to the latest versions.
[Galaxy Tab 4 Original Android Development] matteo0026:
If you want your tablet more fast as possible, LOS 16.0 is the best one. Spoiler: I'm going to upload new builds in the next days.
[Galaxy Tab 4 Original Android Development] TechSharma:
Hi Matteo

I am using this ROM yes it is bit Laggy but very stable though.

With previous 17 & 16 my Tab was rebooting time & again.

One thing for sure on this Rom is that Battery life is half in LOS 18 Vs LOS 17.

Could you please address this issue going forward?
[Galaxy Tab 4 Original Android Development] matteo0026:
I can't do anything. The tab is old and to move these heavy versions of Android a lot of power is needed. Device sources side, they're almost the same for all the versions of Android.
[Galaxy Tab 4 Original Android Development] ashend98:
Helloo.. @matteo0026

I have matisse3g SM-T531, even if the SIM card insert to the tab, it will not be displayed in the tab. Can you provide a solution for this?
[Galaxy Tab 4 Original Android Development] matteo0026:
I still don't have a solution. And I need logs to try to fix this issue.
[Galaxy Tab 4 Original Android Development] neo_sonic:
Hi,

The download links don't work :(
[Galaxy Tab 4 Original Android Development] matteo0026:
Use the mirror (the link of Telegram). AFH is completely down, actually
[Galaxy Tab 4 Original Android Development] Tres_Tigers:
There's the possibility that you need to replace your battery for a much newer, better battery.

However your battery life is in your hands both with what you run, and what brightness you have it set to.

The Display is a huge power drainer.

The only fix is to have it at a lower brightness level, make the screen turn off faster, &/or..

Root your Tablet with Magisk (you can flash the APK files in TWRP and it'll root just like ZIP files).

Then install Kernal Adiutor.

You can use this application to both make your tablet run as hard as it can, like it is already doing on Android 11.

Or.. you can:

Disable some of the CPU Cores..

or underclock it..

To improve battery life, but decrease speed and cause more stutter and issues as things take longer to occur.
[Galaxy Tab 4 Original Android Development] Phillip_2022:
Thanks so much for your work on the Tab 4, Matteo. I just got LOS 17 installed and am enjoying that. Quick question as a noob: when/if I want to put LOS 18 on it, should I be following the "update" instructions (just flashing 18 with TWRP and rebooting), or should I follow the "installation" instructions (and wiping tablet entirely)? Thanks!
[Galaxy Tab 4 Original Android Development] matteo0026:
You have to wipe all the partitions, so you have to follow the "installation" instructions. The update instructions are just to update the same version of LOS.
[Galaxy Tab 4 Original Android Development] Phillip_2022:
Thanks. I thought that might be the case but figured I'd better ask. Appreciate the help and the good work!
[Galaxy Tab 4 Original Android Development] Steelskinz:
I spent some bucks to repair it as it was usb damaged so i change the usb charger and battery but android 5 is a mess..

Could someone help me as i have a matisseevewifi and when i tried to install the lineage-18.1-20221112-UNOFFICIAL-matissewifi.zip it is not compatible.

How could i force it please as when i repaired it i saw some T 530 on a lot of hardware ? I success flashing twrp-3.7.0_9-0-matissevewifi.tar and img. I thought it will work.

Thanks.
[Galaxy Tab 4 Original Android Development] matteo0026:
Matissewifi and matissevewifi are completely different devices. One has sd400 (32 bit), the other one has sd410. Do not try to force flash the matissevewifi build. It wouldn't work.
[Galaxy Tab 4 Original Android Development] Steelskinz:
OK Thanks for the reply. How could i made this old tab a reborn ? I can't see any custom rom. Do you have a better view on that as you are very active on telegram ? Thank you.
[Galaxy Tab 4 Original Android Development] matteo0026:
I have made a LOS 17.1 some months ago, but it isn't daily usable. For example, audio and camera don't work properly. There aren't any other builds for matissevewifi.
[Galaxy Tab 4 Original Android Development] Steelskinz:
Too bad. Do you plan to reupload it somehow ? I can be your beta tester. Thanks.
[Galaxy Tab 4 Original Android Development] matteo0026:
I have a beta tester yet, but I don't have enough time and knowledge to make it working fine.
[Galaxy Tab 4 Original Android Development] Steelskinz:
ok i understand. Tell me if you change you mind one day.. ;)
[Galaxy Tab 4 Original Android Development] Cyrus02:
please help how do we port kmini3g
[Galaxy Tab 4 Original Android Development] matteo0026:
Pick the work done here or in the Galaxy S3 Neo (which has official LOS 18.1) and adapt it for kmini3g, even by looking in the sources of LOS 16. If you are enough knowledged, it would be quite easy, otherwise give up.
[Galaxy Tab 4 Original Android Development] AP29:
Hello !

I am really thankfull for your hard work.

I have just one question:

Is there a possibility to have the app "samsung notes" on tab 4 (matissewifi) ?

I tried to install apk but it is not working...

Thank you a lot.

Sincerly
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi, no you can't install it. Almost every samsung app relies on its framework and services app. Choose another app
[Galaxy Tab 4 Original Android Development] AP29:
Hi,

Thank you for your quick answer.
[Galaxy Tab 4 Original Android Development] Feelfantastic42:
yay. I boot my "matisse" with your Android build and it run perfectly. The YouTube app which previously its laggy so much but now it's run very well.

The only problem what i had is a power which sometimes when i use my tablet, a minutes later it suddenly get powered off itself and also the battery is drain so easily. Just that. Other things they're work great.

So, is there a solution for that problem?

SIncerely,

[Galaxy Tab 4 Original Android Development] Redsand47:
Thank you sir for all your good work. I was able to give my SM-T530nu a new life! I am able to run all the newer apps and very pleased.

Just curious if any plans to enable 5g wifi?

Hi, write in English, please. It's an international forum. Latest twrp is 3.7.0_9
[Galaxy Tab 4 Original Android Development] zanmirco:
Thank you. Link millet version? I see only matisse
[Galaxy Tab 4 Original Android Development] matteo0026:
Open the mirror link. Actually, newest version is in the telegram channel
[Galaxy Tab 4 Original Android Development] GuestNoOne:
Hey,

got SM-T535 and was honestly confused if thats MatisseLTE or MatisseWifi.

Im glad the (newer) -Wifi Build prompted an error and wouldnt flash, so I could use the (older) 2022-09-13-MatisseLTE Build from your androidfilehost.

Flashing and Booting worked.

Thanks for your work.

BTW: You say, the newest versions are on Telegram.

Well, I dont use that service. May you update your androidfilehost or put it somewhere else?

Thank you alot
[Galaxy Tab 4 Original Android Development] Aequita:
Hello matteo, thanks for keeping this old lady alive.

While (mostly) everything works, it feels quite slow and laggy for me in general (even after updating the most recent lineage-18.1-20220913).

Things like apps/menus taking several seconds to open or the System-UI crashing every now and then.

I only use OpenGapps pico and a handfull of random apps on the Tab so it isn't really bloated either.

Is there anything else to update than the ROM itself or am I missing something?

Thanks either way,

Aequita
[Galaxy Tab 4 Original Android Development] matteo0026:

How can i overclock cpu of my tab with this rom? Is possibile to overclock gpu? Thanks
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi, it is not possible actually. Kernel doesn't support overclock.
[Galaxy Tab 4 Original Android Development] FrancoTab4:
Will be supported?

Do you know a way to improve performance/avoid crash of recent game like master duel or something similar? I swap 4 gb ram but it doesnt help it.
[Galaxy Tab 4 Original Android Development] matteo0026:
I don't know, for both questions. I always told that more recent Android versions in this tab aren't performing well. If you want to gain some more performance, use LOS 16.
[Galaxy Tab 4 Original Android Development] Dodekinderen:
Question, is Sm-T533 matissevewifi also supported? i cannot find any ROMS for this version of Tab 4 10.1, i't making me very confused sorry for being stupid xD
[Galaxy Tab 4 Original Android Development] matteo0026:
No and it won't be supported. It's a different device.

Lineage os recovery keeps replacing twrp ,help..
[Galaxy Tab 4 Original Android Development] matteo0026:
If LOS recovery overwrites TWRP when you update LOS, probably you have agreed that option in initial setup. To disable that, open updates page, go in the 3 dots in the upper right corner, select preferences, and then unselect the update recovery option.
[Galaxy Tab 4 Original Android Development] InvertedB:
@matteo0026 stupid queston maybe.

Can I flash the matisse Feb 2023 OTA over the

matisse (10.1) devices (until 2022-09 build) without factory resetting?
[Galaxy Tab 4 Original Android Development] matteo0026:
You should go fine. To be more safe, take a backup before updating
[Galaxy Tab 4 Original Android Development] Play84x:
hi I installed the latest build taken from telegram for matissewifi. I first updated the stock and did all the necessary wipes, the problem is that here in Italy the 5ghz wifi frequencies range from 1 to 128 as a channel. and with these custom roms I can see the 5ghz wifi signal only if I set channel 128 on the modem. while on all the other channels the signal is not visible. would it be possible to do something? could you make a fix? same thing on crdroid, lineage 16 and 17. hope for your help
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi, here it works fine with channel 48, but even the other ones work just fine. The problem is with higher channels, like 15*.
[Galaxy Tab 4 Original Android Development] Play84x:
thank you so much for answering me, in these days I will try again, because the first day I had this tablet in my hands I downloaded and installed a dozen custom roms as the 5ghz signal did not detect me, and I was precisely on channel 106 then I switched to 102 and equally it didn't find it, until I set the maximum channel which here in Italy doesn't go beyond 128. there must be some difference between the nations. but out of curiosity I want to try a lower channel like yours to see if it works as 128 being the maximum channel, when I set it it makes me wait 10 minutes for the fritz box modem as it appears to be a privileged channel. I'll add some screenshots once it's done. Thanks again.
[Galaxy Tab 4 Original Android Development] Minionguyjpro:
Hi therem could you update the version of LineageOS to 20, or is that too powerful? I think it might be possible. Otherwise go as high as possible, please.
[Galaxy Tab 4 Original Android Development] matteo0026:
I'm not able to boot LOS 19.1 and 20, so I think this tab will die with 18.1.
[Galaxy Tab 4 Original Android Development] Minionguyjpro:
Okay. You don't know what is the issue?
[Galaxy Tab 4 Original Android Development] matteo0026:
Probably something related to ramdisk. To be honest, I have tried to boot only 19.1, since it has no sense to go to 20 if 19.1 doesn't boot.
[Galaxy Tab 4 Original Android Development] Minionguyjpro:
I agree to that.

Sim card and gps not working how to fix?
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi, provide logs, please. Without them, I'm not able to investigate on the issue. Thanks

Okay, but how to do it? From the device automatically?
[Galaxy Tab 4 Original Android Development] NaNg2:
hi matteo0026. i'm using Samsung Galaxy Tab 4 10.1 sm531 and i use this build lineage-18.1-20230214-UNOFFICIAL-matisse3g. Sim card not work, Mobile network in Network & internet is disable, IMEI unknow. how can i get log for you?
[Galaxy Tab 4 Original Android Development] dmpronko:
How to do it?
[Galaxy Tab 4 Original Android Development] matteo0026:
@dmpronko @NaNg2 the logcats don't contain anything. To get a logcat, use adb. About the SIM not found issue, get a logcat while the device is booting with this command:

adb logcat -b radio > log_radio.txt

To understand how to get adb, and how to get logcats, look on internet. To be more complete, get a logcat with the base command:

adb logcat > log.txt

[Galaxy Tab 4 Original Android Development] bncd:
Dear @matteo0026

First of all, I noticed that you put a lot of effort into it. Thank you so much.

I know the forum rules. That way the questions are wrong, of course...

But I have very limited time to experience these days. I just want to find the ROM I need and exit. Thank you for your understanding.

Only;

- Mostly the video will be watched. The MXPlayer application will be used.

- Bluetooth headset will be used.

- Sometimes movies will be streamed from Kodi with Wi-Fi

I don't need anything else Camera, GPS, game performance etc. Optional: Google Services also not required.

Which ROM is the best for this situation;

- [ROM][UNOFFICIAL][matisse][millet] LineageOS 16.0

- [ROM][UNOFFICIAL][matisse][millet] LineageOS 17.1

- [ROM][UNOFFICIAL][matisse][millet] LineageOS 18.1

- or just latest Stock ROM.
[Galaxy Tab 4 Original Android Development] InvertedB:
Im running the build from this thread LineageOS 18.1 for the same purposes and have had no issues.

Using FDroid for apps
[Galaxy Tab 4 Original Android Development] bncd:
Thanks for reply.

Oh 18... I wish I had time to try it. I was able to get the tablet for 1 day and sent it to a relative to help with the lessons.

After numerous searches I read that 16 is as stable as possible. And I installed it. I was using 17, after 16 the boot was very fast, it was enough for me.

In fact, in an environment where we can reach 16, 17 and 18 side by side, one of us can perform a performance and battery test.

If I had the time, I would really like to do it. You know, the idea of a side-by-side comparison Youtube video would be great.
[Galaxy Tab 4 Original Android Development] InvertedB:
I use newpipe for Youtube videos. Unfortunately I can't comment on battery as my device has a bad battery, so I normally just leave it plugged in.
