[ROM] SlimSaberKat-jflte-4.4.4-20141014 [unofficial SlimKat builds] for jflte

[kantjer]

SlimSaberKat
Unofficial SlimKat build - Alucard kernel
Rom built with SaberMod 4.8.4 toolchain
Kernel built with SaberMod 4.9.2 toolchain
Fast, smooth and stable​

I proudly present SlimSaberKat.
SlimSaberKat is built from SlimKat source with SaberMod 4.8.4 compiler and "JustArchi's ArchiDroid Optimizations" V3 build optimisations like O3, strict aliasing and many more to make the ROM even faster and smoother. If you want to see all optimization flags set for building this ROM, have a look a look at this commit, line 73-83.
I could cherry-pick some commits ahead from SlimRom team or patches from other repositories if I find them useful.

If you want to know more about build optimization and the build flags used to build SlimSaberKat I can advise you to read this post by @JustArchi.

SlimSaberKat ROM comes with Alucard's great AOSP kernel.

I will follow the weekly and stable builds of the official ROM and if there are interesting commits I will try to make a midweekly build.

F.A.Q

No root
Q: I did a clean flash and don't have root access.
A: Rood access is disabled by default on SlimKat. you need to enable it in "Developer options" set root access for Apps and ADB.

New gapps
Q: There is a new gapps version, how do I flash it.
A: Minor gapps updates can be flashed on top off the old version. For major updates it's often recommended by the Slim team to wipe the systems partition and flash ROM and gapps. Alternatively you can deleted system/addon.d/80-gapps.sh or 81-aio_gapps.sh and flash ROM and gapps. This prevents the old gapps to be restored during ROM flash but will allow you to keep all other custom scripts in the addon.folder.

Removed system files
Q: I have removed a couple of system apps, do I need to do that again after every dirty ROM flash.
A: A dirty ROM flash will restore all the ROM's system apps.You can however use a script to remove whatever you want from the ROM when you dirty flash a ROM. See this and this post on how to do that and many other cool things you can do with those scripts.

DPI settings
Q: How can i change the DPI and what's the original S4 stock DPI.
A: DPI Settings are not included in the ROM yet, until then you can use Texdroider DPI. Default Stock DPI is 480.

New kernel flash
Q:I flashed a new Alucard kernel (or SlimSaberKat with new kernel included) and now not everything is working as expected.
A:This can happen when the kernel settings options are changed (in Ramdisk), to correct this delete the "data/.alucard" folder and reboot. That will reset your kernel setting.

Dalvik to ART
Q: How do I switch from Dalvik to ART, how do I do it.
A: As with every major change, start by making a backup, the follow this tutorial by @Jimsilver73

SlimKat stock kernel
Q: Where can I download the SlimKat stock kernel
A: It can be found here, thanks to @hawkerpaul

Tips and tricks

• If you want to make Slim even Slimmer @s3icc0 made an overview of apps that are safe to remove
  
  
• To make you're phone feel even faster consider lowering "Windows animation scale", "Transmission animation scale" and "Animation duration scale" in Developer options. Also if you are using Nova Launcher you might want to increase the Scroll and Animation speed.

The ROM is build with SaberMod 4.8.3 and all optimisation flags provided by @JustArchi.

And a different kernel.

Lol this is what I PMed you earlier didn't see he made a dedicated thread for it. Be nice to have a SaberMod kernel that supports F2FS as well... Don't think we have one just yet.

This ROM flies though. Great work OP

Great rom but two things I miss: Lockscreen wallpaper and possibility to disable automatic screen dimming. Or should they be somewhere?

The kernel is compiled with SaberMod and currently has support for F2FS

Not an option yet (you can use Xposed though)

...and possibility to disable automatic screen dimming. Or should they be somewhere?

System Settings > Advanced > Device
Turn off CABC (First option under screen tab)

This should stop the screen dimming

Thanks! You know I thought I saw that on the Alucard thread but wasn't sure. I'll have to reflash and give it go

Thanks my friend, very much appreciated :good:

 

[David_cole]

And a different kernel.

I switched straight away (before first boot) back to KT kernel, it's MUCH better than alucard kernel. Other than that the rom seems good so far. (Not as fast as Archi made out in his thread, or even as fast as regular sabermod, but still quite good) thanks for other new rom for our s4 I will continue to to test and give feedback.

Edit: my hangouts notifications don't come thru with the screen off they only show up with screen on
