/* Disclaimer */

Your warranty is now void.
I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this ROM
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you. Hard. A lot.

/* Warning */

Your device's KNOX warrenty will be void just like any other custom kernels
You're welcome to explore the source code and cherry-picking commits
Just don't make another one that's based on my kernel or something so much similar to this
Making mirrors, re-uploading to another servers are strictly prohibited with no exceptions

/* Supported device */

Galaxy S4 LTE-A SK (SHV-E330S, ks01lteskt)
Galaxy S4 LTE-A KT (SHV-E330K, ks01ltektt)
Galaxy S4 LTE + International (GT-I9506, ks01lte)

/* Unsupported device */

Galaxy S4 LTE-A LG (SHV-E330L, ks01ltelgt)
Galaxy S4 WITHOUT Snapdragon 800 SoC

/* What you need to know */

'Opensource' does not mean 'no-respect'
Leave credits to original developers
This is only tested on
- SHV-E330S coming from stock Android 4.4 KitKat
- SHV-E330K coming from stock Android 4.4 KitKat
Other variants, other OS may not be fully compatible

/* Installation */

1. Install ClockworkMod(or PhilZ) recovery
2. Put kernel on you SD card
3. Enter recovery
4. Flash kernel

/* Troubleshooting */

Not booting?
If you don't get passed on "Samsung" white logo, your device is not supported. If you think it should be supported, report to the developer.
Terrible speed or battery life?
Battery life is more likely to be affected by applications. Review your installed applications. Customize the kernel settings to get the most out of it. Trickster MOD is recommended.
Random shutdown?
Attach log(/proc/last_kmsg) or it didn't happened!

Usual questions sorry. .. Does this trip the knox flag in 4.3. Also can you list the main features of this kernal over stock?

Yes, it will void KNOX warrenty.

Mentioned on OP is about all for my kernel

 

[lallolu]

Can you please make a kernel for non-cm devices?

Upgraded to the latest Linux 3.4.91

How did you do this? Can this be simply 'git merged' with the latest kernel.org updates and official Samsung source?

 

[aresbv2000]

It would be nice to have a custom kernel for stock samsung ROM`s. For example...OC, UV, and DT2W functions are awesome.

Project revamped.

Users are now reporting it's ready for daily driver.

I am using latest CM nightly, the arter97 kernel and the arter97 patch from http://www.arter97.com/s4_cm.htm.
I come from a clean install and would like to encrypt the phone. unfortunately it does not work (screen with green robot is displaying, but nothing happens (its not even crashing). could this work maybe with a different kernel? if so, which one could work?

Thx!

Encrypt won't work. Your device is rooted anyways, encryption doesn't mean "secure" when it comes to a rooted device.

Not recommended to do so..

encryption is necessary for me due to policy rules. therefore i need to find a solution
where is the not working encryption located it? rom, patch or kernel? is it possible to do a workaround by f.e. using a different kernel?

Try with solk2's CyanogenMod ROM + his kernel.

I'm sorry but I won't make encryption support in my kernel, as it would break other stuffs.

 

[chillar]

ok, understood. anyways, thanks for your support and quick replies!

 

[leeweijie99]

Hi @arter97. Great job on the kernel, battery life is better and the phone is definitely snappier But I was wondering if you could implement tap2wake in the kernel. S4+ has amoled screen so tap2wake would be really suitable for it. Thanks

 

[jefferzombie]

Hi arter! I'm using CM11 SPL ROM, and flash your 3.4 kernel, than flash a new SPL build, everything is ok and running, but forgot to flash your kernel, so i do it and after samsung logo, screen get black and nothing happens. Wipe data/cache and reinstall rom than boot and running, after flash the kernel, black screen again.
I miss something?
Thank you!
