[KERNEL][4.3][21 Feb.] ★ LiteGX v5.1.0 ★ ... DISCONTINUED !!

AndroidGX · Nov 8, 2013

WARNING :
THIS KERNEL IS ONLY FOR THE GT-I9300 AND ANDROID 4.3 (SAMSUNG) !

This is a pure LITE, STOCK WAY & STABLE kernel with MINIMAL features.

Many of you knows my Android 4.1.2 LiteGX kernel, here is the 4.3 version !

My goal is to offer a slight modification of our Samsung stock kernel's, with few features, aiming a better battery life than stock without affecting any drain.
This is a kernel "plug-and-play" or I would say more "flash-and-play". No need for tools or apps to configure the kernel. This is the way I wanted it. A bit like speedmod kernel did.
Unfortunately, I'am not a developer but just a basic person with some android/linux knowledge already.
My dream was one day to create my own kernel, and thanks to great developers that answered my many questions, this dream has been possible. I'am very happy and proud to share my first ever kernel to everybody here.

It must be only flashed over an official Samsung ROM and not AOSP/AOKP !

Feel free to include my kernel to your ROMs / Threads but please don't forget to inform/ask first via PM and credit me in your original thread.

★ PREREQUISITE ★ :

★ FREQUENTLY ASKED QUESTIONS ★ :

Do I need to flash any cleaner script before flashing this kernel ? :
> If your previous custom kernel dev provided a cleaner script, then you can flash it before flashing mine.
How can I customize this kernel ? :
> Mainly with ZZMoove/zRam profiles (grab them below) and with TricksterMOD / SetCPU apps.
What is zRam and his pros/cons ? :
> Check THIS interesting answer from @Yank555.
Which zRam script should I choose ? :
> Check THIS interesting answer still from @Yank555.
How to check if flashed zRam script is really currently in use ? :
> You can check it directly by using "cat /proc/swaps" or "free" shell commands via a terminal.
What does the LiteGX cleaner script ? :
> It deletes all ZZMoove/zRam profiles that you flashed after this kernel. So you can go in another kernel safely. It don't removes anything else since this kernel is pure stock based and don't add any files/folders that need to be deleted after. This cleaner script will be only efficient in this situation only, it does not clean anything before coming from another kernel to mine.
Do I need to wipe cache + dalvik each time I flash a new kernel version ? :
> Nope. Moreover dalvik cache is already wiped automatically during flashing procedure.
Do I really need to flash any profiles/scripts ? :
> Definitely not. It's user choice to do it.
Do I need to re-flash ZZMoove ZIP profiles each time I flash a new kernel version ? :
> Nope. It just install an init.d script, so it will be permanent until you delete files from your init.d folder or flash "Cleaner" version which will do this for you.
Do I need to remove old ZZMoove profiles manually before flashing a new profile ZIP ? :
> Nope. Each ZIP's include an automatic removal of previously used profile.
My TricksterMOD settings are losed after rebooting ! :
> I won't learn how to use this app but to make short, once you set any value (or modify anything), click the "V" icon at top right to apply new value, then press settings icon of the app (still on top right) and tick kernel parameters option to apply settings at boot.
Android OS usage is very often at top of my battery stats ! :
> Check THIS interesting thread. Moreover it looks android 4.3 source known related problem, hopefully will be solved in another next source.
My device is getting hot at load (games) or high usage ! :
> Check THIS interesting answer from @ZaneZam.
I lost my WiFi connexion ! :
> Be sure to flash an efsV2 modem (XXUGMK6+ minimum).

04.02.2014 : v4.8.0 released.

Removed forced speedmod pegasusq tweaks from ramdisk (back to stock values) to prevent earphone crackles and audio stuttering when listening music (values looks a bit hard at idle resulting this problem). In case you still got the issue with this governor, just switch to another one.
Added "pegasusq profiles" into scripts folder :
- pegasusq_speedmod.zip
Updated "LiteGX-KERNEL_full_cleaner.zip" to match new pegasusq profiles flashable ZIP (please remove old one).

01.02.2014 : v4.7.0 released.

ramdisk : removed a lot of external applets which are now directly included in my BusyBox.

18.01.2014 : v4.6.0 released.

Added "smartassV2" governor (battery is MUCH increased with it at the cost of some lags).
Makefile: Back to stock Update13 source optimizations (I thought it was done already but I forgot it).

16.01.2014 : v4.5.0 released.

Reverted "ignore charger unstable power" previous patch (it was causing USB tethering not working anymore).
Boeffla Sound Engine updated to 1.6.5 (allows speaker volumes down to 20).

13.01.2014 : v4.4.0 released.

"pegasusq" governor with speedmod kernel tweaks (thanks hardcore).
ramdisk: turn OFF debugging for certain modules (thanks hardcore).

11.01.2014 : v4.3.0 released.

TriangleAway support (back).
Unstable power charging ignored (now charging much faster than before)
'pegasusq' governor is now set as default (kernel is much smoother than ever (+ no more random lags ingame/UI) with it).
Enabled all other stock governors ('adaptive', 'conservative', 'interactive') for people who wants to try them out.
Decided to re-include some of my old patches (do not ask me why ^^) :
- Reduced WiFi wakelock.
- Disabled multicast on suspend.
- Proportional rate reduction for TCP.
- Higher random entropy.
- Doubled min-max ReadAhead.

02.01.2014 : v4.2.3 released.

Disabled "CONFIG_SCHED_AUTOGROUP" (useless in Android).

Fixed ExFAT support.

01.01.2014 : v4.2.0 released.

Added hardcore mDNIe sharpness & colors tweaks. Colors profiles remains intact, so they still can be activated in display section (which was not the case in LiteGX for android 4.1.2).

Thank you to support my work guys !

rodlane · Nov 8, 2013

Hi,

Firstly, thank you for your hard work on this kernel.

I flashed the kernel after wiping cache and dalvik. What I noticed is that Trickster mod does not pickup all 4 cores. Only 1 core is shown. Also, frequency lock is set to On, but no frequencies are shown. No scheduler is shown either. Cpu -z shows all cores.

Other than that, everything is running smoothly so far. The wake lock issue doesn't seem to be present. I'll report back with any other issues I find.

Thank you again. I've been using your Kernels since I bought my phone and I find them to be perfect for my needs.

Edit: I'm using Gorgoid 3.2

undeene · Nov 8, 2013

flashing right now. thanks

EDIT: wake up bug is gone. everything seems ok for a few hours of using. next is battery life. charging right now.

maidangisme · Nov 8, 2013

Thanks, you did it faster than i expected, will flash 4.3 this weekend.

Sent from my GT-I9300 using XDA Premium 4 mobile app

F3nr1s · Nov 8, 2013

Awesome i will try it now and tonight or tomorow i will give feedback .
Hope batterylife is better than stock and the wake up bug is gone .
Thanks for your work

modded by Xposed Framework.

Alestilohomer · Nov 8, 2013

Thanks for your work! :good:

Waiting some feedbak from users, but for sure I will try it :highfive:

AndroidGX · Nov 8, 2013

Thanks guys, glad you like it, even if it's still far than my 4.1.2 LiteGX version, still a lot of work to do!

I can confirm this bug, looks like TricksterMOD is not well supported by 4.3 detection for the moment I guess. Try to use SetCPU for the moment which works well, and PerfMon to see behaviour of 4 cores in live, looks like all cores are working properly here :good:

Thanks to informing me about this bug, I wasn't aware of it, since I just migrated to 4.3 yesterday.
For the moment I never encountered this bug so far, but I'll let you know as soon as I'll face it.
I just hope official update12 source solved it, of we will have to wait for non-official dev fix, or future update13 source :cyclops:

rodlane · Nov 8, 2013

Thank you. I'll Perfmon. I don't really play around with cpu settings much, although I do use Trickster mod to check that everything is running the way it should.

Another issue just noticed while typing this post is that my phone is heating up. Cpu-z reading is 40° C. Not sure if it's a 4.3/chrome/kernel issue. I never had this problem 4.1.2 using Chrome.

legacy_thz · Nov 8, 2013

One more kernel for 4.3. This is really good!
Thanks man!

andrewwright · Nov 8, 2013

Stay tuned!
Btw, I found the buggish patch who caused a freeze into samsung I9300 boot logo, it was caused by linux printk, so no kernel logging disabled for the moment.

pendroz · Nov 8, 2013

Looks Nice

Added as always ( Pardus HD Rom Premier 4.3 ) :good:

tuansiro · Nov 8, 2013

Thank! I will try flash right now!!

I Love your kernel for 4.1

, hope this version can fix bug lockscreen delay and batterylife!
