[Galaxy Tab 4 Android Development] mrk2815:
will you have new builds for january for millet wifi .
[Galaxy Tab 4 Android Development] mrk2815:
just because the two developers take different approachs.both roms work and both roms give options to these old tablets to keep them around.glad to se these tablets with roms available for them.
[Galaxy Tab 4 Android Development] DJABHipHop:
Yes once me & matteo fix the 3G on both devices
[Galaxy Tab 4 Android Development] mrk2815:
ok, take your time. no rush and not asking foran ETA. as i know hat you and matteeo are buys working on resolving all issuesand matters related to both tablets. Thanks again . this again is just my media streaming tablet. So dont haveany sensitive info on it or use it for naything beyond straming medai and that sort of stuff.
[Galaxy Tab 4 Android Development] BeeJ1109:
Mrk2815, Please check spelling before posting, so we can understand what you are trying to tell us. It is not that hard!!!!
[Galaxy Tab 4 Android Development] results24:
Hi peeps in not the only one here who would be grateful but would this b adapted for the 7.0 degas version Galaxy tab t230/231 etc
[Galaxy Tab 4 Android Development] results24:
Could this build or something similar work on the t230 or would something in the future of the ancient device I don't think I'm the only one who would be grateful of this build on the 7.0 t230 version
[Galaxy Tab 4 Android Development] matteo0026:
No, it will never get the support from us. If nobody of the owners of those tab 4 7.0 doesn't start to develop seriously, I don't think you'll see something. There are just a few old ROMs. Then, start from there to develop until you come to Android 10.
[Galaxy Tab 4 Android Development] alex.ross:
Lockscreen wallpaper not working. Only home wallpaper changing or home+lockscreen (identical). Lockscreen wallpaper is stored correctly but home wallpaper is used :( please solve it or tell me how to solve it. Thanks
[Galaxy Tab 4 Android Development] IamTheBRAVE:
Try this:

Set Lockscreen+Home wallpaper then change home wallpaper. Do they both change?
[Galaxy Tab 4 Android Development] alex.ross:
lockscreen only : not working (both home wallpaper)

lockscreen + home : working ok

home only : both changing (lockscreen + home)

it seems a bug!

For example in Lineage os for galaxy s advance it's ok!!!
[Galaxy Tab 4 Android Development] DJABHipHop:

[Galaxy Tab 4 Android Development] DJABHipHop:
IK, But I cant seam to fine the cause of the bug
[Galaxy Tab 4 Android Development] starlightknight:
Tried out this rom today on SM-T530NU. It's almost good enough to be a daily driver for me, but the one thing holding me back is that bluetooth audio is not routed correctly for me.

I am able to pair BT headphones correctly, and the system shows the audio as being output via bluetooth- but the audio still actually comes out of the speakers instead.

Attached a logcat from during pairing.

Edit: For some reason, attachment is disappearing - see here for the log
[Galaxy Tab 4 Android Development] Sangean:
Hi,

Do I need to unlock bootloader as a very first step before installing TWRP with ODIN? And if yes, then how?
[Galaxy Tab 4 Android Development] DJABHipHop:
Nope!!!!
[Galaxy Tab 4 Android Development] mrk2815:
for now this is my daily driver on smt 330 NU tablet. That way at least my tablet will b on android 10 instead of being stuck on stock 5.0.1.
[Galaxy Tab 4 Android Development] Sangean:
This custom ROM works fine on my SM-T530.

I only have one comment: Apps download very, very slowly in Google Play Store. I installed GAPPS (nano). Did anyone else experience such thing?
[Galaxy Tab 4 Android Development] HermGerm:
Thanks a lot for offering this. I followed the instructions on getdroidtips.com. It works fine on my SM-T530NU with 16GB. Installed open gapps nano and from there further apps via playstore.

It took me some time to get it 100% working, having had a problem with the /system mount for some reason which did not allow installation/update of apps. But now it works.

Great job, I'm really happy with this solution, and have now a secure, up-to-date tablet which is fine for daily usage - and in German...
[Galaxy Tab 4 Android Development] IamTheBRAVE:
I know you already gave an answer, but, I was thinking about this (again) and was wondering: does Lightning 17.1 have a Q vendor? If so, it should be able to apply android R gsi on it, or am i missing something? What would it need? Is a Q gsi also not possible?
[Galaxy Tab 4 Android Development] matteo0026:
Vendor isn't ''trebilized'', so you can't install GSI. Treble isn't supported and I guess, it'll never be supported, in this tablet, since it's difficult and there isn't that much interest on doing that. Moreover, the normal ROMs aren't still that stable.
[Galaxy Tab 4 Android Development] IamTheBRAVE:
I realised after posting that this tab does not pass treble check so it's not treblized like you said. Thanks for your time👍
[Galaxy Tab 4 Android Development] DJABHipHop:
New update are live no AFH for all Samsung Galaxy Tab 4 Except for the 7.0

[Galaxy Tab 4 Android Development] DJABHipHop:

[Galaxy Tab 4 Android Development] Catatreco:
Great ROM, I'm having a delightful time using my matissewifi (sm-t530) again!

I have just one question, how to disable the hardware keys (recent, home & back key)?
[Galaxy Tab 4 Android Development] Martins2021:
Pfor , alguem tem uma room personlizada ( pode ser 5.1.1 ou 6.0) para galazy tab4 SMT-331

Translation: Please, does anyone have a custom rom (can be 5.1.1 or 6.0) for galazy tab4 SMT-331
[Galaxy Tab 4 Android Development] DJABHipHop:

MENSAJE BORRADO
[Galaxy Tab 4 Android Development] mrk2815:
any new builds for march for q lfr 17.1.
[Galaxy Tab 4 Android Development] TechSharma:
New builds are online I just Noticed. (March 09/2021)
[Galaxy Tab 4 Android Development] 7eter:
somehow the last letter of the name (Unsweeten

d

) went missing with the last version from March 09
[Galaxy Tab 4 Android Development] 7eter:
I have the matisselte(SM-T535) with TWRP installed.

If I try to flash a rom I get a warning:

Unmounting System...

Warning: No file_contexts.

But the script finishes fine with result [1.000000]

When Rebooting I get stuck with the Samsung Tab 4 logo

Interestingly Android folders are being generated in my internal Storage (Alarms, Android, DCIM, Download, etc...)

I also heard a click sound as if i unlocked the screen or something multiple times.

Any hints/ideas?

Help is really appreciated! :)
[Galaxy Tab 4 Android Development] IamTheBRAVE:
In TWRP, there's a "Fix Context" option in advanced menu. Try that.

Hope it helps.
[Galaxy Tab 4 Android Development] 7eter:
Thank you for the quick answer!

I just tried "Fix Context" before and after flashing - but sadly without changes :/

...

Another thing i noticed during flashing. After the warning I get:

"Target: samsung/matissewifixx/matissewifi:5.0.2/LR......." ,"Patching system image unconditionally"

I have the LTE Version - could this be a problem? (i did use a matisselte ROM though o_O)
[Galaxy Tab 4 Android Development] IamTheBRAVE:
Yes, it should be matisseLTE. @DJABHipHop will have to fix it.

EDIT: or you can open the Rom zip file, locate the updater script in meta-inf and modify it.

View attachment 5245219

Edit 2: having same issue on matisse3g. But tab is booting fine.
[Galaxy Tab 4 Android Development] DJABHipHop:
That's Normal
[Galaxy Tab 4 Android Development] IamTheBRAVE:
Thanks for clearing that up. The update works as usual👍 thanks
[Galaxy Tab 4 Android Development] matteo0026:
Since we use an init file to make a common tree for all matisse variants and default fingerprints are too long for bootloader, we use a shorter fingerprint, which is the one of matissewifi. Then, when device is booting, init system applies the right properties, by searching the variant name in the bootloader.

I just wanted to explain better the "that's normal" of DJAB.
[Galaxy Tab 4 Android Development] 7eter:
Any other Ideas/Hints regarding to this?

"Warning: No file_contexts." - Seems to be the problem.

But I still couldn't get the device to boot yet :(
[Galaxy Tab 4 Android Development] matteo0026:
It isn't a problem... "Warning", no error. It'll be always present
[Galaxy Tab 4 Android Development] 7eter:
ah okay - thanks!

So then there must be another reason for my bricked device. :cry:

I looked into the logs.

But I have no experience - this is what I found in 'dmesg.log' that looks at least somewhat suspicious:

Any Ideas what further steps i might go to unbrick this thing? Thank you in advance! :)
[Galaxy Tab 4 Android Development] matteo0026:
Try to flash my los16 and see if you can fix this soft brick. I really don't know why that came out
[Galaxy Tab 4 Android Development] elphio_it:
Greetings to all.

I wanted to know: what is the latest firmware version that I can install on a SM-T535 (matisselte) where the 4G modem also works properly?

I installed the lightning-17.1-20210207 version but unfortunately the modem doesn't work and I need it.

Thanks for the help!
[Galaxy Tab 4 Android Development] matteo0026:
As from other feedbacks, 4G doesn't work in Android 10-based ROMs. You have to flash my LOS16 to get it working. About firmware, it's enough to have installed Android 5 release, better if it's the latest one.
[Galaxy Tab 4 Android Development] elphio_it:
It works like a charm!

Grazie! ;)
[Galaxy Tab 4 Android Development] Yue_Iohikzu:
Greetings everybody, sorry to bother.

Would anybody mind hosting the ROM?

I'm trying to download from the android file host repo, with no luck, getting message o NO mirrors found.

It would be greatly appreciated.
[Galaxy Tab 4 Android Development] Emerson Caitano:
Hello, do you have this ROM for SM-T230NT too? Thx
[Galaxy Tab 4 Android Development] matteo0026:
It'll never be done for tab 4 7.0.
[Galaxy Tab 4 Android Development] DJABHipHop:

[Galaxy Tab 4 Android Development] Bazito:
Hi, I've installed a new update. Unfortunately, it is not possible to wake up the display when it sleeps
[Galaxy Tab 4 Android Development] Bazito:
Tablet normally boot, everything works. The moment I lock the display, it can no longer be awakened. Only a restart will help
[Galaxy Tab 4 Android Development] DJABHipHop:
Can you pull a log because it soes not happen to me
[Galaxy Tab 4 Android Development] Scepterus:
same here, i thought it just shut down, because I have to long-press the power button to get it to boot.
[Galaxy Tab 4 Android Development] Bazito:
where can i find the log you want?
[Galaxy Tab 4 Android Development] matteo0026:
He has a log of it yet since @crazydrive22 got the same issue in his crdroid 6.16. I hope djab will take latest builds for LTE/3G variants down as soon as possible.

The issue happens after pressing ok in the PIN screen in lockscren.
[Galaxy Tab 4 Android Development] DJABHipHop:
I remove them know
[Galaxy Tab 4 Android Development] topsecretasian:
how do you update the the rom? i tried searching update in the menu but couldn't find anything. is there an update package that i have update manually?
[Galaxy Tab 4 Android Development] matteo0026:
Since all these ROMs are unofficial, you need to flash manually every package in TWRP
[Galaxy Tab 4 Android Development] topsecretasian:
i see, but where do i get those packages? i tried looking everywhere but couldn't find any. is it included in the link?
[Galaxy Tab 4 Android Development] DJABHipHop:
Yes it is
[Galaxy Tab 4 Android Development] matteo0026:
What? The ROM packages links are always in the first post of every ROM thread.
[Galaxy Tab 4 Android Development] Exepan95:
the update is bad, made that the brightness control does not work, installed it and it does not work well when set to 0%, it is also full at 100% that there is no reduction! brightness fix the cant this firmware model:SM-331
[Galaxy Tab 4 Android Development] kwisatz79:
Got the same issue on milletlte, though I would not criticize it in such a harsh way.
[Galaxy Tab 4 Android Development] mrk2815:
i'm just sticking with 16.0 till i see a version for the 8 inch version to flash. i looked on DJ AB HIP HOP's lightning fast roms telegram channel but i dont see anything for any 8 inch millet version. so when he has a current one i will flash and try to help out. for now on 16.0 build for now.
[Galaxy Tab 4 Android Development] mrk2815:
i'm going ot retract my statement .i jsu saw the build and will tak a look and download from teh telegram group.
[Galaxy Tab 4 Android Development] mrk2815:
so what are the changes for those who have installed the march 2020 build. have most issues been resolved from thprevious build from february 2020.
[Galaxy Tab 4 Android Development] R0kiss:
How are you able to edit system files? I thought android 10 /system is read-only.
[Galaxy Tab 4 Android Development] R0kiss:
Okay nvm, I fckin did it! #NeverGiveUpKids

Made a magisk module that replaces that file. If you want to try it I will attach zip below (instal trough magisk as module).

If you want, you can extract zip, find the file and edit values to your liking, and make it as zip again. Try to listening to your favorite song at lowest volume, you will hear the difference. If you dont like it you can delete the module.
[Galaxy Tab 4 Android Development] BurnQc:
Finally I installed the lastest build, thanks
[Galaxy Tab 4 Android Development] mrk2815:
how did you install the latest build.can you explain the steps that you took to install the rom.
[Galaxy Tab 4 Android Development] R0kiss:
Download OTA version if you already are on android 10 and just flash it. If you are on lolipop download NON-OTA version(the one with long name) ,arm pico 10 gapps and make sure your twpr is 3.3.1. version, wipe data, flash rom, wipe dalvik cache flash gapps wipe dalvik, reboot, (if you installed nightly build from telegram instal magisk manager apk.)
[Galaxy Tab 4 Android Development] mrk2815:
off to grab the files to do the flash this weekend. anything one should be aware of with android 10 install.should one just install rom an gapps set up and then install magisk or is magisk in the rom already.
[Galaxy Tab 4 Android Development] R0kiss:
Telegram version installs magisk for you, you just need to install magisk manager apk after the flash.
[Galaxy Tab 4 Android Development] mrk2815:
what if your coming from lineage 16.0. so do you just dirty flash the lineage 17.1 ota with gapps from 10 nano or pico. will the nano android 10 gapps package work as well.
[Galaxy Tab 4 Android Development] DJABHipHop:
Backup, wipe, clean, install and restore the data
[Galaxy Tab 4 Android Development] xdacde:
question

How many versions of ARM or ARM64 Gapps are there ??
[Galaxy Tab 4 Android Development] BurnQc:
Reboot to TWRP 3.3.1 recovery

Install the Lastest custom rom.zip

Wipe Dalvik cache

Install the GApp ARM 10 pico

Wipe Dalvik cache

Reboot and wait few minutes

Works on matisse 10.1"

(Sorry for late reply)
[Galaxy Tab 4 Android Development] mrk2815:
DJABHipHop, question, will the rom get updated on a monthly basis with both 10.1 an 8. 0 tablet versions with monthly security included in the 17.1 .just wondering.
[Galaxy Tab 4 Android Development] DJABHipHop:
Yes it does.
[Galaxy Tab 4 Android Development] Vit2410:
Same problem with tablet t535(matisselte).
[Galaxy Tab 4 Android Development] Enzo_P:
Root and use ROOT EXPLORER to edit
[Galaxy Tab 4 Android Development] DJABHipHop:

[Galaxy Tab 4 Android Development] fire_qc:
T530NU I've just flash this from stock Lollipop. Used the file lineage-17.1-20200225-UNOFFICIAL-matissewifi-Unsweetened-XDA-BUILD.zip

Here's major problems I got.

Back camera, can't see anything it's too dark.

Power management, total failure.. The battery in TWRP said 55% but once I boot, after 10 minutes the device shut down by itself. Going back to TWRP and show the battery at 52%!!!?? Open it again, and the battery drain in only 5 minutes and before shutting down, the screen flickered like a strobe light. Right now the device is plugged but it seems to not taking any charge and on the screen I see in the center a big battery logo with a grey lightning in the middle and stays. Not see any % of the battery... After 2 hours of "charging", got no charge...

Please help....
[Galaxy Tab 4 Android Development] acc7:
Hello matteo and DJAB, thanks for your constant effort on Galaxy tab 4.

I've previously installed the Mar.24th version(to matissewifi), and it had a serious problem with the wifi connection via 2.4 GHz. Its wifi speed and latency were terrible compared to my iPhone 6+ and laptop. 5Ghz connection seemed moderate. I've downgraded the tablet into Mar.10th version so I wouldn't be able to provide logs. Sorry about that. Can you investigate and probably add the fix into the next version?

Speed/latency was 3Mbps/200ms at matissewifi, 40Mbps/15ms at iPhone 6+ at the same connection.
[Galaxy Tab 4 Android Development] newrandomaccountbruh:
when treble
[Galaxy Tab 4 Android Development] matteo0026:
Never I guess
[Galaxy Tab 4 Android Development] ceastico:
I have the same problem like 7eter.

„Set Warranty Bit : kernel“ is shown at boot screen (Samsung GALAXY Tab 4 SM-T535) and nothing happens.

On LOS17 the same as on LOS16.
[Galaxy Tab 4 Android Development] matteo0026:
Are you sure to have latest firmware installed? Did you do the 4 needed wipes before changing ROM? It's an issue that's coming from your side, because a lot of people is using these ROMs. But do these tests with LineageOS, since I don't know if everything works fine here.
[Galaxy Tab 4 Android Development] ceastico:
I followed the instructions here:

https://xdaforums.com/t/rom-unofficial-matisse-millet-lineageos-17-1.4263849

(I could also continue the discussion there, if you suggest so)

...but got the same result. Of course, I wiped the 4 options system, data, cache and dalvik/art cache.

What do you mean with "firmware installed"? How can I install firmware apart from flashing TWRP?

Thank you very much for your work and help!
[Galaxy Tab 4 Android Development] matteo0026:
Ok, wipes done are fine. To check firmware, look into this app: https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo

Compare with latest version of firmware of your region by looking into sammobile.com/firmwares .
[Galaxy Tab 4 Android Development] ceastico:
I am not sure, how I can look into that app if I cannot boot the Tablet...

I remember, that before wiping and trying with the Custom ROMs, there was Android 4.4.2 on the tablet.

Does this mean anything for choosing the right firmware here?
