Yes Newpipe is great. The feature of skipping silent parts is unique.

I've been using my tablet as a 2nd screen for a very long time. (via Spacedesk) One day I looked, my battery was swollen (it was constantly using the laptop's charge), the tablet might almost explode. I don't recommend it to anyone. Do not misuse anything for a long time. Systems can be damaged.

That's why I bought a new battery. The new battery is of course not original. But it's fine. On Lineageos 17, I was able to watch movies for 6 hours with the new battery. When I switched to Lineageos 16, it took relatively longer.

Anyway, for this forum topic 18. If I have the opportunity to try 18 one day, I will definitely give an opinion.

Thank you our dear developer for providing us these versions.

@matteo0026 do you have a video to how install this rom? excuse me for my english. thanks
[Galaxy Tab 4 Original Android Development] bncd:
Hi! Where are you from? I'm from Turkiye! (Eğer Türkçe biliyorsan yardımcı olabillirim)

Dude, you don't need to watch a video. Just read the steps carefully.

First install TWRP. Here is the latest version: https://xdaforums.com/t/recovery-3-7-0_9-unified-matisse-millet-rubenslte-twrp-recovery.4019831/

Read the TWRP installation steps carefully. You can even ask ChatGPT if you don't understand. Or you search in Youtube: "install twrp samsung tab 4" You can see a lot of videos...

Then install the ROM. Please also read ROM installation steps carefully.

Remember the whole secret is TWRP. If you manage to install it, everything will be very easy. You can easily do everything in this advanced recovery screen. It will probably also have an interface in your native language.

@matteo0026 How did you get los 19.1 to even finish building? i got so many errors it wouldn't even build. If you have your broken los 19.1 trees somewhere please push them so i can attempt to get los 19.1/20 booting
[Galaxy Tab 4 Original Android Development] ROM_gamer987:
Bit of an update, tried flashing los 18.1 on my tab 4 (T530) From 4.4.2, After flashing i'm stuck on the tab 4 boot splash, I can't reflash original fw from odin as this device has a broken usb data pin. I tried getting all of the partitions from stock fw zip (5.0.2) and flashing manually by creating a twrp zip. All the partitions flashed but it still won't boot. I'd also like to point out that it boots in the background as i can hear the lock/unlock sound but it stays in that splash (not bootanimation, galaxy note 4 splash)
[Galaxy Tab 4 Original Android Development] matteo0026:
I've fixed several building errors, but I've gave up and deleted everything. I have no sources saved.

About the booting, it was written that before flashing the LOS, you have to start with stock 5.0.2 firmware. Probably you didn't flash every partition, and in a correct way. You should repair your tab and use odin to flash stock firmware.
[Galaxy Tab 4 Original Android Development] ROM_gamer987:
I Managed to get my usb port working and flashed 5.0.2, it all works now. As for LOS 20, i got multiple errors related to perfetto even after applying the needed patches for 3.4. Would be nice to see the android 13 taskbar on this ancient device although multitasking is almost impossible with 1.5 gb of ram
[Galaxy Tab 4 Original Android Development] Kornor:
Good evening everyone,

I have a problem that is getting me crazy. I think I have followed all the steps well, however once the ROM is installed, and the Gapps too, ('ve tried various and possible) once the device (535 LTE) is started, it restarts with an error in the background, starting data factory reset. What could it be? a kind soul who can help me?

I haven't done a flash for years and I'm not very knowledgeable.

Thanks in advance
[Galaxy Tab 4 Original Android Development] andr_SMOLKEYS:
@matteo0026 So I seem to have an issue regarding wifi. At first, it was perfectly fine. That is, until I installed a magisk module. After the install (reboot and all that), wifi was no longer working properly. It still connects fine, but it can't connect anywhere and I can only get it working again with a reflash (or just a data wipe, but I haven't tested this).
[Galaxy Tab 4 Original Android Development] sadskull:
hi, thanks for ths great rom.

i try to find a way to activate gesture navigation bar but the system navigation menu seems to don"t be reached.

does anyone have any idée about this issue ?
[Galaxy Tab 4 Original Android Development] anthony80200:
@Kornor in TWRP after you have wiping the tablet do back and do a format data (the button is next to Advanced Wipe).
[Galaxy Tab 4 Original Android Development] Andrius_S:
Good evening everyone,

First of all, I would like to thank matteo0026 for this great ROM.

I'm using Samsung Galaxy Tab 4 10.1 SM-T535 and I'm trying out the build "lineage-18.1-20220913-UNOFFICIAL-matisselte.zip".

I noticed an annoying issue regarding real-time-clock (RTC): every time I restart my Galaxy Tab 4, the RTC is reset to build date/time (2022-09-13 11:46:02), when "Use network-provided time" is off.

Is this an known issue for You? Is this solvable on somehow?
[Galaxy Tab 4 Original Android Development] Minionguyjpro:
Hello @matteo0026,

Maybe you can release another security patch for this ROM? There hasn't been a patch since February, so yeah.
[Galaxy Tab 4 Original Android Development] matteo0026:

Any news about Lineage OS 19.1 or 20.1 booting on galaxy tab 4
[Galaxy Tab 4 Original Android Development] speedracer69:
SM-T530NU​

TWRP 3.7.0_9​

Format and then load:

Matissewifi SM-T530 - T530NU

lineage-18.1-20220913-UNOFFICIAL-matissewifi.zip​

The Samsung logo will not change. It just hangs.

Any suggestions in troubleshooting?
[Galaxy Tab 4 Original Android Development] syabus:
My thanks to matteo0026 for this program. It brings new life to my SM-T530 tablet.

Installed lineage-18.1-20220913-UNOFFICIAL-matissewifi.zip on T530NU.

There is a new patch lineage-18.1-20230614-UNOFFICIAL-matissewifi.zip released a few days ago that is supposed to hold the date and time after restart.

Since I am new to Lineage OS, should I use TWRP Wipe > Advanced Wipe > Select system, data, cache and dalvik/art cache to clear up for the new patch?

How about GApps (Arm)? Should I reinstall it again since GApps is the program that install the Lineage OS? Please correct me if I am wrong.

Any help will be appreciated. Thanks.
[Galaxy Tab 4 Original Android Development] SPG_4545:
GApps just installs google apps
[Galaxy Tab 4 Original Android Development] syabus:
Thanks for the reply.

Should I just use TWRP Wipe > Advanced Wipe > Select system, data, cache and dalvik/art cache to clean up in order install the new patch?

If so, after downloading the update onto the tablet, will it automatically does its thing to install the new update.

Previously, GApps was the last program to be installed and it automatically download the Lineage OS onto the tablet.

Thanks.
[Galaxy Tab 4 Original Android Development] SPG_4545:
You shouldn't even need to Wipe anything I think
[Galaxy Tab 4 Original Android Development] syabus:
Ok. I will try that then.
[Galaxy Tab 4 Original Android Development] Andrius_S:
Thank You, matteo0026, for the quick fixing of the problem with date and time after restart.

Unfortunately, I have found another problem in the newest version (I'm using Samsung Galaxy Tab 4 10.1 SM-T535 with the build "lineage-18.1-20230614-UNOFFICIAL-matisselte.zip"): it's issue regarding Camera application... This app crashes by the start of app when the Camera's setting "Power shutter" is on (see an attached crash report).

P.S.: this problem was not observed with the build "lineage-18.1-20220913-UNOFFICIAL-matisselte.zip".
[Galaxy Tab 4 Original Android Development] syabus:
Are you able to let me know how you update the patch from lineage-18.1-20220913-UNOFFICIAL-matisselte.zip to lineage-18.1-20220913-UNOFFICIAL-matisselte.zip. Do you just install the update patch over the old patch or you have to use TWRP to Wipe > Advance Wipe all the files as done during the stock installation? Thanks.
[Galaxy Tab 4 Original Android Development] Andrius_S:
I'm using "Advance Wipe" on all partitions (dalvik/art cache, system, data and cache) before installing a new build of Lineage OS.

And yes, after that it is a real headache to install all needed apps and make settings for OS and newly installed apps. Some users are using a special software solutions to migrate all data and settings, but I'm an old-fashioned man. - I'm doing that manually ;-)...
[Galaxy Tab 4 Original Android Development] Yulian7000:
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
[Galaxy Tab 4 Original Android Development] Tres_Tigers:
You shouldn't even need to use special software to install the newer versions.

Just install the zip like normal and everything will stick as it's just an update would, not a full system replacement.
[Galaxy Tab 4 Original Android Development] Minionguyjpro:
Hello @matteo0026,

I have saw someone having a SM-T536 as model, which is the Korean version with a different CPU, as I heard. Might it be possible to add support for this model? Thanks in advance.
[Galaxy Tab 4 Original Android Development] matteo0026:
It won't be added. It has an exynos 7870. If you want to add support for it, check the work that has been done to the other Galaxy devices with that SoC.
[Galaxy Tab 4 Original Android Development] MD24:
Hi matteo0026,

Thanks alot for this Rom. I have a Tab4 SM-T531. I have installed the lineage-18.1-20220913-UNOFFICIAL-matisse3g and open_gapps-arm-11.0-pico-20220215 using twrp-3.7.0_9-0-matisse.

Everything works for me but I am facing an issue with certain apps. I am getting a message "Device is untrusted" while using those apps. Is there a way out for this?

P.S. Forgive me for being naive but, I have installed lineage for the first time.
[Galaxy Tab 4 Original Android Development] matteo0026:
First of all, why did you install the build of 2022-09? I wrote one post before that I've published the builds of 2023-07... anyway...

Which apps are you talking about? I think the only way to fix this is to install magisk, and then install the safetynet fix module: https://github.com/kdrag0n/safetynet-fix/releases
[Galaxy Tab 4 Original Android Development] MD24:
Thanks for the reply.

I have already installed magisk, post installing the above mentioned rom and gapps, but I am still getting the same message. The apps name is "Qubo" by Hero Electronix Pvt. Ltd. I wanted to use my tab as a screen for door camera.

Will it help if I reinstall the latest version of Lineage? Will also try installing safetynet fix module update here.

**Update**

All Sorted out. Found factory stock image and firmware here.

__________________________________________________________________________

Hi,

Working on updating 2 - T530NUs from 4.4.2 for my kids and having a heck of a time finding a reliable download for firmware 5.0.2. Its been about 6 years since I've rooted them, but I have the latest version of TWRP on there now, and just going to wipe them clean anyway.

I've tried searching on the forums and between the chaos of my kids getting ready to go back to school and forgetting to take my adderall, I've been going in circles for the last 5 hours.

Could someone please post a link to a clean download for the firmware and latest build for Lineage?

Thanks!
[Galaxy Tab 4 Original Android Development] IsmailUmmer:
Can I flash this on Sm-t230?
[Galaxy Tab 4 Original Android Development] matteo0026:
Is it written somewhere that device is supported? Only the tab 4 8.0 and 10.1, and not every model (the supported ones are written in the downloads)
[Galaxy Tab 4 Original Android Development] syabus:
I flushed my Samsung Tab 4 10.1 with the new patch lineage-18.1-20230714-UNOFFICIAL-matissewifi.zip.

The update went smoothly but I lost my WiFi 5G after reboot. I have 3 routers with the 5Gs and non are showing on the Tab 4 after the update. 5G WiFi was present before the update. I did toggle the WiFi on/off switch on the Network and internet but still not showing the 5G.

The 5Gs are working on my other devices, like the Android phone and Laptop, so there is nothing wrong with the routers WiFi 5G.

I appreciate if someone in the forum can provide me tips of how to get back the 5G WiFi?
[Galaxy Tab 4 Original Android Development] DerivativeOfLog7:
Are you still using this ROM? Is performance still good? I'm currently running LOS 16 on matisse and I'm evaluating whenever or not I should put 18.1
[Galaxy Tab 4 Original Android Development] Texidar:
I used it for about a year and had no complaints. I sold it sometime in 2022. I needed something with a better processor and more ram.
[Galaxy Tab 4 Original Android Development] syabus:
Update.

After much fiddling around, I change the router WiFi to Chnnel 36 @20Mhz and bingo, 5G appears on the Tab 4. All is good now.
[Galaxy Tab 4 Original Android Development] TheGamerKing:
Do you still publish standalone Lineage Recovery images like you used to do on your old Android File Host page for the Galaxy Tab 4? I know that when updating LineageOS to a newer version it automatically updates the recovery (correct me if I'm wrong). Also can I flash LineageOS for the first time using Lineage Recovery not TWRP? Can you also please install ih8sn (a safetynet fixing package) by default so that the ROM passes SafetyNet by default? This will be really useful as it works without root.
[Galaxy Tab 4 Original Android Development] DerivativeOfLog7:
Does ADB work on this ROM? It keeps saying device offline
[Galaxy Tab 4 Original Android Development] andr_SMOLKEYS:
It does. I used it just recently.
[Galaxy Tab 4 Original Android Development] LordGummyWolf:
hi Matteo,

can you tell me if lineage os 20 will come for this tablet?

anyway i want to thank you for your great work :)
[Galaxy Tab 4 Original Android Development] DerivativeOfLog7:
For some reason it keeps going offline a few seconds after plugging the cable in when I try it
[Galaxy Tab 4 Original Android Development] SteinbeckFan:
I never could figure out how to get ADB working. Was about to give up on the whole project when I discovered a utility called Odin. Using Odin I was able to install TWRP and all my problems were solved :-) Just giving some advice here, there may be some utility to using ADB, especially if you enjoy typing in arcane unix commands with lots of switches and other arguments. Otherwise install Odin.
[Galaxy Tab 4 Original Android Development] DerivativeOfLog7:
They have nothing to do with each other. Odin is for flashing partitions on Samsung devices, ADB is for managing and interacting with the Android OS while it's booted. One can't replace the other and vice versa
[Galaxy Tab 4 Original Android Development] DerivativeOfLog7:
aaand it looks like it was the cable... the same cable that I use for many other devices, the same cable that works on the same tablet in download mode, magically dies when I try to use it for ADB

Thank you tablet, I needed a reminder of how god awful micro USB was and how blessed we are today with type C :)
[Galaxy Tab 4 Original Android Development] DerivativeOfLog7:
After using this rom for about a week... I confirm what the developer said, Android 11 is a bit too much for this tablet; the performance is certainly better than crDroid, but it's still laggy. Android 9 runs noticeably better (especially with a Substratum theme that fixes the half baked dark mode ;) ) (both without gapps since they are too resource hungry, and I don't need them on this device)

UPDATE 13/09

Pie was giving me issues, so I'm retrying this one... this time I installed truly the bare essentials, and even disabled all animations... so far it seems to perform well, hopefully it won't degrade

I'm having a small issue....

If I play a video with mpv, HW+ (mediacodec) mode gives the whole video a green tint

HW (mediacodec-copy) works fine, but it's laggy, way more than just SW mode

I attach a logcat I made switching from SW to HW+

Hi.

I installed on my SM-T530 this LineageOS, and updated with the 20230912 version.

One think: Trust informs me into the the Android Security Fix the vendor.img file is deprecated/obsolete.

(Settings > Privacy > Trust)

An idea/suggestion to update it?
[Galaxy Tab 4 Original Android Development] hantigor:
Спасибо за обновление. Долго выбирал разные сборки - всё в хлам. Установил LineageOS и теперь планшет ОПЯТЬ ЖИВЁТ! Да еще и обновляется. Работает всё: WIFI, BT, приложения по маркетплейсам и т.п., достаточно "тяжёлые" программы. Есть притормаживание, но это МЕЛОЧИ!. Спасибо за работу!!!

Mod Edit: English Translation Below

Thanks for the update. I spent a long time choosing different assemblies - everything was in the trash. I installed LineageOS and now the tablet is LIVE AGAIN! Yes, and it is updated. Everything works: WIFI, BT, marketplace applications, etc., quite “heavy” programs. There is a slowdown, but these are SMALL things!. Thanks for the work!!!

Any way to disable smart cover/flipcover/whatever it's called? I don't have one and my laptop's magnets keeps activating the sensor
[Galaxy Tab 4 Original Android Development] Roady_7:
Hi,

New member here, and trying to upgrade my Samsung galaxy Tab4 MT-530 from Android 5.x.x to a higher version.

What I already did:

I installed this firmware: lineage-18.1-20230214-UNOFFICIAL-matissewifi.zip

This version didn't get stuck asking for the simcard.

After installing the tablet runs perfectly fine.

Then, the Gapps.

I thougth Android 11 needs a Gapps for this version 11, so I installed this file:

open_gapps_arm_11.0_pico_20220215.zip plus a lot of other versions.

But after installing in TWRP it keeps on giving me the message:

"Please download the correct version for your ROM: 7.1.2 (SDK 25)

Alright, then I found this file: BeansGapps-full-7.1.x-20170725.zip but gives the same error messages.

2 questions:

1: why does it seem I have a version 7 ROM while I installed a version 11?

2: which file fits the ROM version?

Thanks in advance.

And thank you very much for having created the upgrade!
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi, first of all, make sure to download always the newest builds of the ROM and the gapps. Unfortunately, opengapps have been discontinued, and actually the most supported package of gapps is mindthegapps, which you can find it here https://wiki.lineageos.org/gapps . Gapps 11 are correct, so no problems there. It asks for Android 7 gapps because TWRP is based on that android version, but probably TWRP was wrong at reading LineageOS system properties. Which TWRP did you install? SIM card warning in the initial setup can be skipped by rotating the screen vertically (probably that menu hasn't been adapted for the horizontal tablet format).
[Galaxy Tab 4 Original Android Development] Roady_7:
Thank you very much for your help Matteo.

Alright, I took the latest ROM version lineage-18.1-20230912 and installed it

I wiped the Dalvik, system, data and cache folders.

Then immediately after that I installed MindTheGapps-11.0.0-arm-20230922_081034.zip

Then I see this error: "could not mount /mnt/system"

I 've searched around this forum, but it's not clear what caused this error.

Any hints how to solve this?

Plus: when I reboot the Tab4 from this point, it's not starting up Android, it 's starting the download mode.
[Galaxy Tab 4 Original Android Development] matteo0026:
Probably system partition is messed up. Install stock firmware at latest version and restart from scratch
[Galaxy Tab 4 Original Android Development] Roady_7:
Thanks!

I found a stock rom for my tablet and installed it.

Then again:

Downloaded the twrp-package

Ran into recovery mode

Installed the Lineage package and the MindTheGapps package

Same error message: "could not mount /mnt/system"

I've no idea what I'm doing wrong.

If you have more ideas I would like to hear from you.
[Galaxy Tab 4 Original Android Development] matteo0026:
You have another step. Find a pit file and add it in Odin when you flash stock firmware. In this way, even deeper partition issues should be fixed. By the way, you haven't answered me to one question: which TWRP are you using? I mean, the package name. And which is the model of your device?
[Galaxy Tab 4 Original Android Development] BeeJ1109:
Hi Matteo,

Firstly when will LOS18.1 be updated. I am assuming soon.

By the way I am finding last update is OK. But finding Tab 4 Millet appears to getting slower in response. Click on any app on Home Screen. Wait a long time, until is responsive and usable. I have cleaned out the cache in TWRP and rebooted ROM. Even tried to dirty reflash.

Using same apps as usual. I always update as required.

I did a Factory Wipe, then Stock, then cache wipe, then system wipe, then updated with LOS 18.1. Reinstalled apps from backup. Usual Gapps PICO.

Still Slow response. Also tried Reflash of Backup ROM, via TWRP Restore.

Same Slow Response. Using Latest Magisk for ROOT.

Any Clues ??. Has other users reported this issue ??.

Cheers BJ
[Galaxy Tab 4 Original Android Development] matteo0026:
Sorry, I can't do anything. The tab is this, the ROM is this. I haven't touched device sources since long time. If you want a faster ROM, switch to LOS 16 or 17.1.
[Galaxy Tab 4 Original Android Development] DerivativeOfLog7:
I updated and now it's bootlooping 🫠
[Galaxy Tab 4 Original Android Development] matteo0026:

Hi Matteo,

I have the same problem. I have recently obtained this tablet, installed TWRP and then lineage-18.1-20231023-UNOFFICIAL-matissewifi.zip but the device reboots into TWRP after a few minutes of LineageOS logo animation.

The same thing happens with lineage-17.1-20231018-UNOFFICIAL-matissewifi.zip
