I have just installed Magisk and to edit the files, I use Solid Explorer as file manager. It works very well. No permissions touched or whatsoever. If you really want to stick your changes, you can try, in TWRP, to adb pull that file, edit it and push it. That is impossible that can't work
[Galaxy Tab 4 Original Android Development] FailSafeNow:
Solid Explorer. Maybe I will try that and see if it works. I typically use FX File Explorer. It has root access and can mount the System directory as Read/Write, but maybe Solid Explorer does something extra.

I need a tester with matisse3g or millet3g to try to fix SIM. If someone can, ping me here or on Telegram (same username)
[Galaxy Tab 4 Original Android Development] frankykw:
After using the ROM a few days, I think its because the tablet is underpowered for the youtube app today, thats why the issues happens quite often but not always.

I had download earlier version of YouTube (14.43.55), and it looks like the problem is gone
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi everyone. Probably September patches will go out a little bit later because I did a lot of changes on and under the hood!

Little suggestion... I've fixed back dark camera and videos recording. Videocalls work well with Hangouts, Meet and Duo, with Skype cameras stay black. I'll work on it. But hey, it's a lot since the point we were before! To keep you updated, you can check our Telegram group @ Galaxy_Tab_4

Need some tips about rooting the device

Hi, i would like to root the tablet (530NU) Model. After flashing gapps, i flashed supersu 2.46, then i encounter a bootloop, i know that i'm doing something wrong i'm kind of a newb here ! Thanks in advance. (In any case, the rom is working flawlessly and very stable without root and with pico gapps)
[Galaxy Tab 4 Original Android Development] MbMax:
I premise that I've installed the previous version and for my exigences the tablet (matisse 10.1) is perfect. The app which I use to read the newspaper doesn't work anymore on Android 5, so I'm very happy to have in my hands an almost brand new tablet which works fine with Android 9.

Only one question. In the first page there's written that the last update is related to 2020-09-08. Why in the download space I see only the version 20200808?

Thanks...
[Galaxy Tab 4 Original Android Development] mrk2815:
he's working on that new build. he said it would be pushed as soon as he was done with it.
[Galaxy Tab 4 Original Android Development] MbMax:
Many thanks for your answer. :)

I've searched between the last posts without find the answer. Probably I've missed something.
[Galaxy Tab 4 Original Android Development] matteo0026:
You remained in ancient times where SuperSU was good (like Android 6-7). Now there is Magisk. Just Magisk. Install it and you won't have soft bricks (bootloops) anymore.

In first post it's written at the end the date when I update that post (just to clarify, or add/remove issues that are present in the ROM)

Anyway, a new update is online! Tomorrow I'll do another post where I'll write all the (big) changelog. For now, I compiled for matissewifi and matisselte. You know that I make builds with this order, as always: matissewifi, matisselte, matisse3g, milletwifi, milletlte, milletltetmo, millet3g.
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi guys, I had to take down the builds that I uploaded for matissewifi and matisselte because they had WCNSS_qcom_cfg.ini file in wrong directory (the good one is /system/etc/firmware/wlan/prima). Now I'm rebuilding those 2 (matisselte has been reuploaded yet) and making all the others.

So, let's go to the changelog:

- September 2020 security patches

- (for matisse devices only - about millet, I still have to get one feedback with jack - speaker isn't needed since it has just one speaker) invert left and right channel for speaker and jack (before, left and right channel were inverted)

- remove buttons backlight settings since we don't have them

- faster bootup (it uses all 4 cores instead of 1 now) (about 5 seconds less)

- fixed back dark camera

- fixed recording videos

- now, hangouts, meet and duo can be used without any problem. Skype has black front and back camera. Other apps haven't been tested - I'll update first post with some other apps

- some other fixes under the hood
[Galaxy Tab 4 Original Android Development] mrk2815:
matteo, the 9/13 build that you have on android file host for millet, wifi sm330 nu wifi does not work with

wifi as far as connecting wifi. have gone back to august 8 build and everything is working fine.just wanted to let you know. the single speaker works fine as far as that you wer worried about.
[Galaxy Tab 4 Original Android Development] zebetti:
matteo, the 9/13 build for t330 - back camera doesn't worked on my device.
[Galaxy Tab 4 Original Android Development] matteo0026:
In millet, the problem with audio could have been the audio with 3.5 mm jack, not the speaker.

About wifi, I have to know if the file WCNSS_qcom_cfg.ini is in /system/etc/firmware/wlan/prima (with the other 2 wifi-related files). If yes, I need a logcat, if no, check in /system/vendor/etc/wifi. If it's there, move that file to /system/etc/firmware/wlan/prima.

If you have T330NU, probably I know which is the problem, otherwise, I need to get a logcat.
[Galaxy Tab 4 Original Android Development] mrk2815:
is the 9/13 with the wifi fix or not.the samsung millet wifi in question is smt330nu. i willl try another clean flash of the 9/13 build and see what happens. is there a good app to get a log cat.
[Galaxy Tab 4 Original Android Development] matteo0026:
All the uploaded builds should be good, so 9/13 should be good. I've deleted 9/12 builds which weren't good for sure.
[Galaxy Tab 4 Original Android Development] zebetti:
my device is sm-t330.
[Galaxy Tab 4 Original Android Development] mrk2815:
matteo, let me do a clean install as i have been lazy, and doing dirty flashes. lets se what happens after a clean install. let me do tha tin in a few days as ia havea few otehr project that i am working on and i will definatelly let you know. .
[Galaxy Tab 4 Original Android Development] mrk2815:
matteo, i had a little bit of time after some wwork projects this morning.i did flash the tablet smt330nu with a clean flash of 9/13 lineage 16.everything is now working with wifi, dont know waht ws wrong teh last time when i did it. But ow its workign and no wifi issues whatso ever with millet wifi smt330nu.
[Galaxy Tab 4 Original Android Development] mrk2815:
heres an odity after i did the clean install and played with the tablet fora few hours and if i use an ad blocker application like ad guard or blokada, wifi stops and the only way to have it work is to disable the ad guard or blokada.these are ad blokers with their vpn built in.is there something going on that is messing with wifi that you have in the builds of 9/13 compared to other older builds.i did not experience this till i had more time and more time with the build today. So that is the only issue i do see.i am using twrp 3.4.0.3 and not 3.4.04 of the twrp recovery with millet wifi smt330nu. What could this be and how could this be solved. .

---------- Post added at 06:23 PM ---------- Previous post was at 05:50 PM ----------

figure out what the issue with ad guard.there is a bug in ad guard official. they told me to take a test drive of nightly and to turn off stealth mode in ad guard settings when using with ad ugaurd guard vpn . that is what happened and things are resolved and media plays with wifi enabled. i need to se if that could be something similiar with blokada .but with adguard i know the issue an its not on your end but on the ad guard end to fix the bug that they have in stealth mode and their ad guard vpn service .
[Galaxy Tab 4 Original Android Development] matteo0026:
I've found the error. I had to add in the CameraWrapper milletwifiue and matissewifiue to the devices. Otherwise, it can't take the right properties. I could send a new library that includes that, or wait a new build in october. As you want.
[Galaxy Tab 4 Original Android Development] mrk2815:
left and right channel speaker being inverted .i cant tell the difference.both are working when plugged into headset on headphone jack, playing youtube and other music apps. if that is what your saying.
[Galaxy Tab 4 Original Android Development] FailSafeNow:
The left and right audio assignments were not fixed in this build. I am disappoint.

I found a way to fix the file through TWRP. But I am still disappoint.
[Galaxy Tab 4 Original Android Development] zebetti:
i can wait - no problem. thanks.

:good:
[Galaxy Tab 4 Original Android Development] Souf0:
Hello,

First of all, thanks to [MENTION=6798358]matteo0026[/MENTION] for your work.

I installed TWRP 3.4.0-3 in my SM-T530 device, then I installed latest latest build and ARM 9 pico package gapps.

After wipe cache, I rebooted my device, and stuck with the LineageOS logo.

I can enter in TWRP, but device can start Android (LineageOS 16).

What's wrong?

Regards
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi, did you do the 4 wipes indicated in first post? Do you have lollipop baseband? Did you install TWRP app? (Never do this, otherwise, you risk to do a bootloop)
[Galaxy Tab 4 Original Android Development] Souf0:
Hi,

I had stock ROM.

I've not installed the TWRP app.

I don't see in first post nothing about 4 wipes:

Instructions :

Download the latest build and gapps (ARM, 9.0, I advice pico package)
Boot to recovery
Flash the latest build
Boot to recovery again
Flash gapps
Reboot

Regards

Edit:

If I install the gapps (open_gapps-arm-9.0-pico-20200919.zip -md5 is ok-) it stuck at LineageOS logo, if I install only the LineageOS build, it works (sometimes).
[Galaxy Tab 4 Original Android Development] matteo0026:
You had stock ROM, ok, but which? The one based on kitkat or the one based on lollipop. It isn't obvious that everyone update their device.

About instructions, let me update them, I thought it was written. Anyway, you have to go to wipe > advanced wipe > select: dalvik/art cache, cache, system and data (and eventually, internal storage, if you want to clean all /sdcard directory) > swipe to wipe > go to home and install ROM and then GApps.
[Galaxy Tab 4 Original Android Development] Souf0:
Hello,

I had stock lollipop ROM.

I wiped all partitions (except sdcard), because I didn't think it was relevant, isn't?

Regards
[Galaxy Tab 4 Original Android Development] matteo0026:
You did right. The problem is: what prevents tablet to boot ROM? Where does it arrive? Just bootlogo or bootanimation too?
[Galaxy Tab 4 Original Android Development] Souf0:
Boot animation (circles moving in the lineage logo).

If I wipe partitions, and install latest build (formatting after cache and dalvik), works, but if I install gapps, stuck at animation logo.

After a lot of time, reboots automatically into twrp.

[Galaxy Tab 4 Original Android Development] matteo0026:
Then, try to install stock firmware with Odin (I advice you to use Frija as firmware downloader - google it), do a first boot, and then try to reinstall twrp (latest - 3.4.0-3 since you have matisse) and after, do the wipes and install rom and gapps
[Galaxy Tab 4 Original Android Development] FailSafeNow:
Hey, I had a similar problem. It was caused by the Official TWRP App. TWRP helpfully suggests that it install the app for you after you've installed an operating system or whatever. In most cases this is just fine. But not with this ROM. With this ROM, it breaks everything and you can't boot. I tested this myself. If you do an installation with the TWRP app, it won't boot. If you do an installation that's completely identical EXCEPT that you don't install the TWRP app, it boots fine. Sounds strange, but it's absolutely true. Matteo and I talked about this some pages back.

So if you installed the Official TWRP App, try the whole installation procedure again, including wipes, without installing it. There's an option in there somewhere to keep TWRP from even offering the Official App. I forget precisely where, but it's easy enough to find it.

Matteo, were you going to modify the first post to include a warning against installing the Official TWRP App?
[Galaxy Tab 4 Original Android Development] Souf0:
Yes, but I reply always "Do Not Install" to install the app (install app and create as system app).

The strange thing is that stuck at boot animation if I install the gapps (all md5's are ok).

Edit: I tried with sdcard wiped, and same result (I think it was obvious, because sd is only an external partition)
[Galaxy Tab 4 Original Android Development] Souf0:
After some tests, I finally installed LOS16 & gapps. I only do two things different:

Boot the device unplugged

Install from internal storage (instead of sdcard)

Thanks to all
[Galaxy Tab 4 Original Android Development] Hugiinn:
hi, since i have installed the rom the tablet randomly powers off, even if charged, which didn't happen in the stock rom.

It's only me or it happens to somebody else?
[Galaxy Tab 4 Original Android Development] matteo0026:
First post updated. Wow, there are always things to precise! But, if I want to do a good work, that's it.

Work that, to be honest, I slowed down these days.

No problems here. And I've never heard someone that reported this issue. But, what do you mean by "tablet randomly powers off"? It reboots or just turns off? Or, is it on but screen keeps black (black screen of death)?
[Galaxy Tab 4 Original Android Development] djhooker:
Yesterday, I had that issue, too. When I started the device, it restarted when I opened an application. Shortly before, I could see that the device had no network connection. A few hours earlier I configured 2 settings: A new lockscreen and 2 routers of my home wlan. Later it turned out that one of the routers was configured incorrectly and that the DHCP IP address assignment was not working correctly. I switched it off. So far there have been no other unexpected restarts. I don't know whether there is a context, but it cannot be ruled out. I only know this behavior with sudden reboots from smartphones when the battery has aged a lot. Perhaps the Tab4 is already old, even though a actual operating system is installed ;)
[Galaxy Tab 4 Original Android Development] FailSafeNow:
Will you have the audio channels fixed for the next build? Like I said, I got mine fixed, but it'll be easier if I don't have to do it every time I install a build.
[Galaxy Tab 4 Original Android Development] matteo0026:
Fix is present in september build yet, if I'm not wrong.

Anyway, for you of the forum too, I tell you that I've partially fixed offline charging. Now, you can't see the state of charge of tablet (you can't see the white icon of battery that indicates that is charging and at which level is), but tablet just shuts down. I want to fix this as soon as possible because in next build I want everything (offline charging) will be working as it should.
[Galaxy Tab 4 Original Android Development] FailSafeNow:
Speaking of charging, now I don't know if this is a problem that other people have, but after my tablet charges up to full, it won't do any more charging until I reboot it again. I have ACC installed. I can watch the power drain. I unplug and plug back in, but the battery keeps discharging. No matter how low it goes, it will not charge. It won't start charging again until I reboot the tablet.
[Galaxy Tab 4 Original Android Development] matteo0026:
Uninstall ACC and then test another time.

Anyway, offline charging is fixed, I'll send good builds when october security patches will be online.
[Galaxy Tab 4 Original Android Development] Woodbuger:
Fantastic! You're the man. Thank you for you're hard work and dedication.
[Galaxy Tab 4 Original Android Development] wilsonaitan:
thank you, awesome. just need to upgrade my TWRP from 3.0 to 3.4 1st before I can successfully install this. Cool Mannn
[Galaxy Tab 4 Original Android Development] mrk2815:
its good that i have stuck with you with the tablet and the roms. i will stcik it out with you if you decide to go to lineage 17.1 down the road.i will stick with you with what ever rom you support for the tablet.
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi guys, new build with 10-2020 security patches is online!

Changelog:

- October 2020 security patches

- Fixed Wi-Fi display

- Fixed offline charging (finally!) just for matisse variants

- Sepolicy is now cleaned up and fixed everything

[Galaxy Tab 4 Original Android Development] Souf0:
Hi,

Offline charge works perfect!

Thanks matteo
[Galaxy Tab 4 Original Android Development] mrk2815:
cant wait to test it out when it comes to millet wifi smt330 nu .

AT&T Build?

Hello, can someone help me out please as I am a little confused. Is there a build for the AT&T (SM-T337A) build?
[Galaxy Tab 4 Original Android Development] Sayueri:
I updated to the October build on my SM-T530NU. Offline charging works. Press power button to check battery charge. Home button doesn't work for that. Only used tablet briefly since update. Didn't notice any issues so far. Keep up the great work Matteo.
[Galaxy Tab 4 Original Android Development] mrk2815:
very smooth and snappy. thanks for the build. we will se what you come up with next builds. hoping ath when you have working , you may think about lineage 17.1 down the road.
[Galaxy Tab 4 Original Android Development] cooperke:
latest build matisselte t535 and bluetooth keeps stopping..... any fix for it.... did clean install but that didn't fix it.
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi, T337A can't be supported because of its bootloader

Home button can't work unless I patch ROM source. So, no way...

I won't support 17.1 until everything will be fixed here. And my PC isn't really good to handle newer versions of Android to build... It takes a lot of time on Pie yet.

This is a known issue, but it's a random one. To be more precise, device isn't able to read EFS, where the MAC Bluetooth address is written. The strange thing is that I've fixed that issue, so there could be something else... I don't know. I need another log while ROM is booting.

Anyway, I have good news for you. By checking camera issue with skype and jitsi, I saw that they're the only ones to support Android 6.0+, and the other ones 5.0+. So, to make these 2 apps working (for now), you have to download these versions of the following apps:

Skype: 8.15.0.430

Jitsi: 20.3.2

Edit: Skype Lite doesn't work. I really don't know why. I'll investigate on it.
[Galaxy Tab 4 Original Android Development] Woodbuger:
Offline charging not working for me. Clean installed October milletwifi build on SM-T330NU. From powered off, plug in charger and battery icon appears for a couple seconds then tablet boots normally. If I plug in with tablet on it charges normally. Any ideas?
[Galaxy Tab 4 Original Android Development] Woodbuger:
Since no one else with t330 reports offline charging problems guess I'll try going back to stock rom and flash to this one.
[Galaxy Tab 4 Original Android Development] matteo0026:
By talking with other millet owners, millet has still that issue.
[Galaxy Tab 4 Original Android Development] tyler45_09:
Can i setup android 5.1 + apps on Google play?
[Galaxy Tab 4 Original Android Development] FailSafeNow:
I have a small issue. I sometimes get audio stuttering. It happens when something busy is happening on the screen, like scrolling text or an audio spectrum display or something. I haven't seen the problem with video. I don't know why something like scrolling text would grab enough resources to make the audio stutter. And it only happens if I have something like that on the screen. If I'm looking at something else or the screen is off, I don't have problems. It's an annoyance more than anything. Do you have any insight on the problem? Thanks.
[Galaxy Tab 4 Original Android Development] matteo0026:
You mean, apps that require Android 5.1 and superior? If that, yes, you can install them. Except for Skype and Jitsi apps. Look issues part in first post to focus on this issue.

Can you explain better with which app does this happen? I want to reproduce the issue, since I've tested in youtube app and it works fine.
[Galaxy Tab 4 Original Android Development] FailSafeNow:
Mostly I see the the problem with Spotify (or Spotify+ as the case may be). I believe I've seen it sometimes with Podcast Addict, but it's not doing it now.
[Galaxy Tab 4 Original Android Development] matteo0026:
Probably it's because of CPU overload... I've tried it, but it didn't happen.
[Galaxy Tab 4 Original Android Development] mrk2815:
just like you, matteo, i run a bunch of media apps on the tablet an don't notice the issue either. i have the millet wifi sm330nu model. this is my streaming device as its got a big battery and can go for days at a time wwhen i am working out in my home gym.
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi guys, new build with 2020-11 security patches is online!

Changelog:

- November 2020 security patches

- Fixed (my fault in previous build) time that was wrong when device device was turned on from a while

- Slightly lighter kernel, some debug has been disabled and system should be snappier

Ah, I forgot a little thing... Now I wrote stats of downloads of this ROM in a spreasheet. Link here: https://docs.google.com/spreadsheets/d/1m137iOL1TDNIGNYx2ppO3y2u7tlIca7-yADw1iGDjcE/edit?usp=sharing
[Galaxy Tab 4 Original Android Development] djhooker:
Thank you matteo0026 for your great job and keeping my old Tab alive :)
[Galaxy Tab 4 Original Android Development] matteo0026:
Little news... I fixed Print Spooler and Email apps (blame a wrong configuration of DPI for apps) and in milletltetmo [MENTION=8771630]DJABHipHop[/MENTION] tested my fix about battery percentage, which in next build will work well. Moreover, in millet devices I've found a wrong value of DPI for the system screen. Before it was 320 (probably taken from s3 neo), and in next build will be 213, like in stock ROM.
[Galaxy Tab 4 Original Android Development] DJABHipHop:
This also aply to my ROM as well.
[Galaxy Tab 4 Original Android Development] matteo0026:
Brightness bar behaviour has been fixed too.
