I ended up pulling the getprop stuff out of updater-script and it installed with no issues. Just had to google a bit. Thanks for this! I'm happy to find anything for these tablets, they are old but handy and I have several of them so this is nice. Also installed Magisk (should have done that ages ago, the last time I messed with this stuff was 2014/2015) Thanks again!

TWRP is the problem.
[Galaxy Tab 4 Android Development] PratelD92:
I'm running 3.0.0.3 on a SM-T330, that's the latest one I can find for this tablet.

I had an issue with rotation where it basically wouldn't rotate regardless of the settings.

This post (https://xdaforums.com/xperia-tablet-z/help/lineageos-auto-rotating-solved-t3736105) solved it for me.

I don't know why the links are dead but here is another route that should work. Install Telegram if you do not have it and join the Galaxy Tab 4 site. Once you do that, type #twrp and you should find what you are looking for. I hope this works for you!

Can we get a Halium build (Most preferrably Plasma mobile or Ubuntu touch)on the Tab 4? I tried previously, but failed due to the lack of a graphics vendor blob.

[Galaxy Tab 4 Android Development] Texidar:
Thanks so much for everyone involved in this. :) :good:

I figured I'd post what worked for me, since it took a bit to get what I needed together due to some dead links.

My Device: Galaxy Tab 4 8.0 (milletwifi)

I was running TWRP 2.8.3.0 with CM14. I could not install lineage-16.0-20191110-UNOFFICIAL-milletwifi-Unsweetened-XDA-BUILD.zip with this version of TWRP. I updated to TWRP 3.3.1-0. The recovery is .img and so I simply used 7zip to archive it into a .tar and used Odin 3.09 to install it.

After that I did a full wipe and sideloaded both "lineage-16.0-20191110-UNOFFICIAL-milletwifi-Unsweetened-XDA-BUILD.zip" & GApps Nano for ARM Android 9.

My device is working much smoother now on LOS16 compared to CM14.

Thanks again.

Need advice on using the Light Project...

Hi,

It's so good to see someone has fixed the camera and microphone, so I hope that is working for all.

I have an older Samsung Galaxy Tab 4, which I've been running under an older CyanogenMod setup/ROM. See some details below:

My tablet: SM-T530 Model

My Android: Android version 7.1

My Mod: CyanogenMod version 14.1-20161117-0709-UNOFFICIAL-matissewifi

Build date

Nov 17, 2016

Build number

cm_matissewifi-userdebug 7.1 NDE63X e93aca0a67 test-keys

CyanogenMod API level Guava (7)

Android security patch level November 5, 2016

I'd like to update to your ROM/Mod, but wondering if I should reset the device to factory first? Or do you think I can just install it OVER the Matissewifi mod I have on there now?

I'm attempting to setup the old Tab 4 as a "smart display" in my kitchen area. Having the camera and mic would be awesome, because if it works, I can do video calls via Duo.

I tried yesterday to use my setup with Google Assistant, and it couldn't hear me at all (re: that old mic problem).

Appreciate any input and advice.. thank you, DrWeb
[Galaxy Tab 4 Android Development] TripodKnight:
14.1 without GAPPS

I haven't checked development for the Tab 4 in a year or so, thank you for fixing the camera and mic!

Is it possible to get a de-googled version of this rom? I don't use google play services (or chrome or any other GAPPS) and have the tablet run faster without them.

Thanks!
[Galaxy Tab 4 Android Development] TripodKnight:
For anyone else who is considering this ROM, the bluetooth audio didn't work (which is a must for me). I flashed this older ROM instead. Though on this one the microphone and camera do not work (I'd like them but bluetooth is more important for me).

[Galaxy Tab 4 Android Development] DJABHipHop:
1) Down all the files and put therm in the exterinal sdcard under a folder called Pie so you flash then all at once in oder.

2) Disable all tweaks.

3) Back up current rom to extreinal sdcard just in case something goes wrong.

4) Reset the device.

5) Flash all the files at once in order by selecting the ROM, then opengapps, any any other m9de you like, includeing opengapps sinec Pie ROM doea not inclede them.

6) Restore the data only from previous ROM wait till it done reboot.

7) Renable all tweaks and enjoy.
[Galaxy Tab 4 Android Development] DrWeb2:
Thanks for the nice outline, extra cool. Turns out, I was curious and figured you had moved on from this project.. so I followed the guidelines on the project, TWRP etc., and it worked just fine. I think it did include the opengapps, as all those seem to be present after the 2nd reboot (as instructions said). I have the microphone working, which enable Google Assistant for my "smart display" in the kitchen. I have a camera! and tried some video calls on DUO, aced it.. so many thanks for the project. First-rate, easy, and powerful :) ..take care, DrWeb aka Michael... p.s. I used the UNOFFICIAL, and since I hadn't tweaked the prior ROM a lot, I didn't mind just letting it go. I was going to build the new ROM up from ground level with widgets, music, video, kitchen apps, news, etc. --to enjoy while in the kitchen.

I also had to do that. My device is: SM-T535 (LTE). Is it the right ROM for me?

Also:

The file I'm using is lightning-17.1-20220912-UNOFFICIAL-matisselte-Unsweetene-XDA-Build

because the newest

lightning-17.1-20221009-UNOFFICIAL-matisselte-Unsweetene-XDA-Build.zip is only 69.7 MB (and of course corrupted / can not be opened).​

Hey

I installed this rom and booted successfully. After that I installed openGapps and SuperSU zips, but now it seems to be on a bootloop of the lineage OS boot thing... it's been about 20 minutes so far anyway!

Is it likely the SuperSU zip file has messed it up? Is the ROM automatically rooted? And was ARM 7.1 gapps the correct package?

Thanks!
[Galaxy Tab 4 Android Development] DJABHipHop:
What Need To Be Done in order of importance.

Fix sleep of death in TWRP.

Fix clock in TWRP display wrong time with correct time zone.

Take the ugly out of TWRP by bring it Into the modern age(Not necessary).

Make stander SOC vendor & board repo for all msm8226 devices.

Fix device tree and make device more stable.

Fix camera & microphone.

Improve device performance/and battery life.

Repeat step 4 for all millet devices.

Clean my GitHub, device tree.

Make better rom for older/legacy devices like the tab 4 or newer device like the tab E.

Debloat & simplify rom for older/legacy devices & none tech-oriented people.

Make rom layout as close to stock Samsung as posable without the ugly color.

Upgrade device to pie or newer.
[Galaxy Tab 4 Android Development] matteo0026:
You have to use magisk or addonsu for root. SuperSU is deprecated.

Yes arm 7.1 is correct.

I'm up and running now, so you were right it was that zip. I'll look into both options :)

Hmm. Wipe all

please i´m need help...omg
[Galaxy Tab 4 Android Development] Advanced07:
Are you sure your device is lte and not the wifi version because it says that it is not for your device and your device is SM-T530 instead of SM-T535. Try to download SM-T530 version.
[Galaxy Tab 4 Android Development] jctedax2:
I'm sure, I have a mobile phone operator card and the tablet is the 3G version, but I'll try the rom for the wifi only mode.

thank you ;)
[Galaxy Tab 4 Android Development] Advanced07:
Did a clean wipe and installed this rom, mic works but not sensitive enough, set it to permissive and it is usable but still unresponsive not smooth like the gpacnot version. Both have a 2,4ghz wifi bug where it refuses to connect you have to wait like 10/20 mins for it to connect. And i don't think the wifi range is fixed. Wifi should be the devs main priority because of how often you use it this is very annoying. Hope you will fix :)
[Galaxy Tab 4 Android Development] DJABHipHop:
Im working on it
[Galaxy Tab 4 Android Development] jctedax2:
Odin mode

ops, I have installed the version for the wifi model and although I did not give any error, now soo I have the boot screen in Odin mode ... I have flashed the previous rom and it does not boot either, soloOdin mode ... what can I do?
[Galaxy Tab 4 Android Development] Advanced07:
Weird, format everything and try flashing the previous rom again.
[Galaxy Tab 4 Android Development] jctedax2:
I have already tried it but I can not get it, it seems that it installs but it ends quickly, it restarts and returns to Odin mode.:confused:

Now I try to install this rom: lineage-14.1-20170309-0134-UNOFFICIAL-matisse3g and it gives me the following error:

E3004: this package is for device: matisse3g, matisse3gxx, matissewifi, matissewifiue, matissewifixx; this deviceis matissewifi.

updater process ended with: ERROR: 7

And I am quite sure that my tablet is the model SM T535 with 3g

I do not understand: someone knows why the installation says that the device is only wifi when it is the 3g model?

Thank you for ur help guys...omg
[Galaxy Tab 4 Android Development] leonardus_magnus:
Yes.... Happens with my device too (SM-T535)...

Just extract upadater-script from my .rar file and replace the updater-script in YOUR_ROM.zip\META-INF\com\google\android using WinRar...

Close winrar, send to device and flash with TWRP...
[Galaxy Tab 4 Android Development] DJABHipHop:
Well SM-T531 is 3G model & SM-T535 is LTE model, But the reason there are no new SM-T531 rom because the 3g outdated

Thank you DJABHipHop to continue the dev on that old device. I've a little problem (not see in this thread), I've a big battery drain.

Previously I was with RR (since 2 years) and my battery hold 1-2 days with normal usage, but with your rom, hard to stay 1 day without plug the TAB 10.

I have done all the install process in "the rule of the art" (I'm on december 12 build)

Anyonelse has the same drain ?
[Galaxy Tab 4 Android Development] Advanced07:
Idk don't notice a difference on this rom, other roms also last just as long for me (1 day max)
[Galaxy Tab 4 Android Development] matteo0026:
Yes, and logs talks clearly, there is something that is draining... I found some other users that got this error on logcat, but I don't found the fix.
[Galaxy Tab 4 Android Development] Thargorsson:
ok so for camera...

This is probably well hidden by samsung but theres a property which sets the hardware version... the libmmcamera_XXX checks that one to be exactly like 4 (S3Neo had that case).

The fix was to create a shim for the libmmcamera_XXX so that it reported the original value from stock. For this i had to install stock get the property value compare it to my latest LOS. I created the shim then and added it to the LD path and et voila it worked. The think is that samsungs lib simply return a NULL value or undefined structs to the kernel if the hwver isnt the correct one...

Link how i did this is here:

https://github.com/S3NEO/android_de...ommon/blob/lineage-14.1/shims/imx175_shim.cpp

The revision on our device had to return an integer higher than 3 otherwise the lib would return NULL.

For microphone look at the mixer_gains.xml and compare it to the one from my repo or klte
[Galaxy Tab 4 Android Development] DJABHipHop:
Same here I typically get a day of battery with light usages and less on a heavier usages plus you factor in all crap in LineageOS that are not needed on a tablet.
[Galaxy Tab 4 Android Development] DJABHipHop:
Thank I'll send you the file telegram, then make a test build for you to test while I fix my tab 4 10.1 T530NUBNN with won't boot any rom other than stock. i'll have a look mixer_gains.xml to see if i have one plue after the camera & microphone gets fixed, I'm going making a new rom that's lighter than Lineage OS with, no default Lineage OS apps Except Recorder & modded wallpaper app with no wallpaper, no default Wallpaper, no ringtones, no screensaver, Simplified setting app like IOS, super clean lockscreen, The Hacker Keyboard,Replace default Lineage OS apps with google equivalent, small ui tweaks, but yet keep it all customizable enough like barebone rom basically leave it all up to the to the user install there favourite apps, wallpaper, ringtones, ETC...
[Galaxy Tab 4 Android Development] Advanced07:
What i would do if i made a rom for this device

* Keep it clean as possible let the user download whatever he wants (so basically lineage os)

* Vulkan support (if its possible)

* Smooth rom with no bugs (animations on 0.5)

* Some customization like the resurrection os

* Android Pie ui if is possible (is better tbh, no need to make a new rom because by the time its finished this device will be dead)
[Galaxy Tab 4 Android Development] matteo0026:
After making work well the ROM, so we can work on adding features. But for now, don't ask anything...
[Galaxy Tab 4 Android Development] DJABHipHop:
I agree with you, if we where fix all the minour bugs on Nougat then yes the device would be dead by the time where done, but if we just fix the camera and microphone then go stright to pie then thats a diffrent story now and the device wont be dead at all simply because we be adderss the little thing in Pie as we go reather than in Nougat or Oreo.

It all boils do to where you want stable Nougat rom or a the lasted Pie rom with stabilty fixes as we go.
[Galaxy Tab 4 Android Development] Advanced07:
Stable nougat is better i think because Pie doesnt add anything new andere useful, i dont think there is any upside. Nougat Sith Pie ui would be better. And what is the point of fixing camera aand add all that stuff if its tot get abandoned anyway? We already have pac rom for camera and mic. So in my opinion you should either make this rom perfect or stop developing and move to pie.

(Also wtf i deleted dalvik and normal cache and my tablet reset it self?? Luckily my files are still there is thuis a bug with the ROM or did i misclick???)
