Being a SlimRoms fan, I looked everywhere for up to date versions of Slim5 or Slim6, and after I couldn't find any newer Slim ROM for my SGH-M919, I decided to compile one. By God's grace, it worked! I hope that other's can enjoy this ROM too, so I put it here to share it with you!

**** This is an UNOFFICIAL ROM. Install at your own risk! ****

Gapps link:
http://forum.xda-developers.com/slim...imkat-t2792842

I have personally tried the Slim_zero_gapps.BETA.5.1.build.0.x-20160429.zip file, which worked flawlessly. Be sure to slap their thanks button for the Gapps!

This Rom has been very stable for me. Be sure to follow these installation steps very carefully, as they may be different then what you are used to.

Installation instructions:

-Download ROM and gapps, and put them on your phone or external storage.
-Reboot into recovery mode - TWRP (I personnally am using 2.8.7.0).
-Backup what you had. (Just to be safe.)
-Wipe.
-Install Rom.
-Wipe Cache and Davlik. <--VERY IMPORTANT!
-Install Gapps. - Optional.
-Wipe Cache and Davlik again! <--VERY IMPORTANT! Or WiFi may not work first boot. Will work thereafter.
-Reboot to system and enjoy!

Code:
What works:
-So far everything that I have tried works, such as
 - Phone calls/receiving
 - Data 2g/3g/LTE
 - Bluetooth
 - WiFi
 - MTP
 - GPS
   etc....

What doesn't:
- I have not found any big errors, fault crashes, or problems yet. Please let me know if you find an issue!
- I have posted a few notes in Post #2 below.

Disclaimer: SlimRoms is not responsible for any damages to your device.

In the Rom, I left the original SlimLP boot animation, however, I have made a couple of simpler custom boot animations for SlimRoms, which you can find here if you would like to use one of them instead:
http://forum.xda-developers.com/slim...ation-t3377271

This SlimLP ROM was built for the JFLTETMO, the T-Mobile Samsung Galaxy S 4. However, The updater script has been modified, and it would allow itself to be installed on any of the Galaxy S 4 devices. I have not tried this on any other device, but you are welcome to try it AT YOUR OWN RISK.

A huge thanks to the SlimRoms team!

Notes: a place for notes about the ROM.

Background image
The futuristic and really cool background images used in this rom were provided by The Quiet Learner, you can visit his website for more information and more really great pictures. https://qlfiles.net/


Security Updates
As of February 2016, the SlimRoms team has stopped updating SlimLP with security updates. I have decided to continue updating SlimLP, but only with Critical security updates from the Android Security Bulletins: https://source.android.com/security/bulletin/index.html. Please note that I am only updating Critical updates, not High, Moderate, or Low security threats. I am doing this by hand and may miss one update. Please be advised that this rom is not as secure as Marshmallow roms that are kept up to date. I am doing my best, but I may also be a little behind the bulletins. Please be patient. I decided Critical updates were better than none, but I can only do Critical updates, as this sometimes takes editing over 800 files per monthly bulletin.


Camera
Every now and then, when I use the built in camera app, it will take 2 or 3 pictures, and then the camera picture button will be grayed out, and you must exit and re-open the camera app to take more pictures. This does not happen with Open Camera app, which is available online or at the play store. Overall the camera seems to be working great, I'm not sure why the built in app sometimes has this issue.


GPS
GPS seems to take an unusually long time to get a fix, even outdoors in the open sky. It does work and stay locked for me, but I thought I would share, in the event others noticed this as well. @redx64 has pointed out that you can speed up the GPS by downloading GPS Status and toolbox and use fastergps to update your GPS config file to your region.


Gapps or no Gapps?
For those who do not wish to install, or who are prohibited from installing Gapps, there are some great alternatives. Aptoide works really well in general, and I did take some time to test it with this ROM. As for my apps, Aptoide had all but 2 of the apps I use available, and many alternative apps as well. If you wish to forgo Gapps, but still want a login, app searching, automatic updating (or not, depending on your settings), user friendly tool, then you might want to give Aptoide a try.


The best way to use layers successfully with this ROM:

After doing some testing of the layers on SlimLP, I learned a few helpful tips.

1. The PlayStore Layer Manager App is too "new" for SlimLP. The 4.+ version available from the PlayStore will not let you undo the layers, and hense you cannot go back to stock. Use this older version (3.5) instead, which allows you to install, apply, delete, and undo changes:

https://www.mediafire.com/download/q94w8j7xuyhpudz

2. The PlayStore layers themes are often incompatible with version 3.5 of the layer manager app. Don't worry though, there are tons to choose from here on XDA:

http://forum.xda-developers.com/show....php?t=3011075

This Mega thread has tons of them to choose from. If you want these, only download the ones that are zip files for best compatibility. The zips should show up in your download folder, which you can move anywhere and use from the app.

The app has an option to "delete" layers, which actually means "undo" that layer, not actually delete the zip file.


If you still wish to use the PlayStore app and themes, keep in mind that you cannot "undo" your choice of theme. And sometimes themes have an undesired side effect. Two themes from the PlayStore that I have successfully used were BluSky theme, and Elixium theme, both of which worked well, with the exception of the systems -> battery settings chart looked funny.

If you use the themes, I highly recommend doing a TWRP backup first, to make sure that you can always go back!


Governors:

If you want to save battery life, I recommend that you use the "No-frills CPU Control" app and set your Governor to something like Powersave or SmartMax, and your I/O scheduler to Noop. This may affect performance slightly, but will save on some battery power.

If you want to increase performance, I recommend that you use the "No-frills CPU Control" app and set your Governor to Lionheart, Ondemand, or Performance, and your I/O scheduler to CFQ. This will boost performance slightly, but will have a negative impact on battery power.

Powersaving <----------> Performance:
Powersave, SmartMax, Conservative, Interactive, Lionheart, Ondemand, Performance.


Fast Charge:
To use Fast Charge, you must enable it in the Kernel Adiutor app. If you want to set custom settings, you will need to get another app from the Play Store, such as Device Manager or other apps that allow you to control the fast charge settings. Note that some fast charge settings apps do not change the appropriate values to function. The lockscreen may still say "slow charge" as the rom itself does not natively support fast charge, even though the kernel does.


Also, if you have any questions or comments (even if you didn't like it) about this ROM you are welcome to post them in this thread. SlimRoms is not for everyone, since it is rather "slim". No sense starting a Q&A thread for this ROM when we already have a thread here...

Thanks for your work on this. Really miss having a SlimRom, used to run on my SG4. With all the BT issues plaguing MM ROMS currently, I may give this a whirl.

Thanks. I did test the Bluetooth, but I do not use it much. It would be good to know if this Bluetooth is rock solid when it comes to headphones, speakers, and such.

I should think BT is fine, as devs had it working pretty much 100% for the LP ROMS.
MM seems to have changed something that hasn't quite been solved yet.

Please let me know if I am wrong, but can't we use this version also?

Be sure to slap their thanks button if you enjoy their ROM!

Edited: I now see that it does not work on the M919. I am currently pursuing SlimRoms 6.0, but perhaps I can look into it. No promises, though.

Its a rough build with little updates
As you know you cannot flash jfltexx versions of the ROM
If you want to you need to flash a xx recovery






Could you add super user to settings

(I feel dirty unicorn covered the most ground with its settings menu



Feels like slim always misses something so I finished testing an went back to a previous ROM
