You will void your warranty after flashing this kernel
I'am not responsible of any damage caused to your device after flashing this kernel

Some reading..

This kernel must be only flashed over an official LG ROM and not AOSP/AOKP (like CyanogenMod, etc) !

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.

★ WHAT TO EXPECT ★ :

(over a pure stock kernel) :

Better battery life and overall performance experience
Trying to include only efficient (but not so much experimental) tweaks
Stay as close as possible from pure stock source

Base :

Directly based from latest available "LGH815_Android_Marshmallow_V20j" Android 6.0 source from LG (for clean work and stability)

Ramdisk from 20g stock kernel
Stock Linux 3.10.84

Main :

Auto install SuperSU 2.79 SR3
Auto install BusyBox 1.26.2
Native ExFAT support
FIOPS scheduler added
noop as default I/O scheduler
Optimized other stock schedulers for SSD's
All TCP congestion control modules activated with Westwood currently as default
SElinux set to "Permissive"
Stock ZRAM enabled (may be configurable with scripts provded in downloads section)
Logd disabled
init.d support
USB fast charge (but disabled as default)
KCAL post-processing driver
DriveDroid support

Welcome to LG's world. Good luck with your job.

Gorgonije · Jan 10, 2016 at 8:22 PM

Welcome my friend! Nice job!

DaarkieDoo · Jan 10, 2016 at 11:12 PM

Any reason why you'll never add overclocking/underclock? It's your kernel and you're of course allowed to do whatever you want with it [emoji14]

Because:

I'm not a fan of those things, as it is source of many instabilities and not recommanded for long term (reducing life of components, a bit)
I found the LG G4 already powerful enough for my daily use

:highfive:

Rosa Elefant · Jan 11, 2016

Welcome to LG! I like your signature. "If you take life too seriously : just undervolt it." Heh, yes, instabilities...

I'll keep an eye on this kernel for experiences. I hadn't tried a custom kernel on my G4 yet...
Looks like this one is less likely to break things than others.

viruz82 · Jan 11, 2016 at 10:42 AM

SD card failure. Unusable for me. Back to stock rooted.

Corrupt sd card... going back to stock and waiting for a future release. In lupus kernel works fine too.

Thanks for your work anyway

AndroidGX · Jan 11, 2016 at 5:51 PM

Thanks guys for the report about ExFAT issue, I'll fix this very soon :good:
(I wasn't aware because I still have my old 32gb sdcard so cannot test personally, I will attach a beta here in my next post, so you guys will confirm if it will work :good

Stay tuned!
Cheers' :good:

AndroidGX · Jan 12, 2016

Can you guys please try ~~this beta~~ version and report if ExFAT is working.

(If not, I have another solution but will take me some time :good

'laters

*new beta2 to test, please download it HERE and report*

Sd card issue

zuqka10 · Jan 14, 2016 at 6:50 AM

Tested beta 2, still no go for sd card.

Hoffmanns · Jan 14, 2016 at 7:53 AM

I have not problem with SD card because I using old 32gb card.
But overall performance is great and battery seems great too.
Im tested all custom kernels for LG G4 and this kernel seems good maybe best of all...

Thanks guys for your report. I know where the problem is, I'm currently stuck at signing exfat module step. It will be fixed asap (I hope) :good:

Thanks for your report, if you wait for official v1.0.1, you'll even be more surprised, removing a bit more both thermal and random lags :good:
