I read somewhere that H815 kernels are compatible with H811, so maybe you can backup your boot image (just in case) and try to flash my kernel to check? :good:

Also, please don't forget to report, so I can add this information into first post (with proper credits of course) :highfive:

[G4 Original Android Development] bendancin:
Wow Thats awesome. Have Do you changed anything on this Kernel with Kernel Auditor or is all Stock configuration?
[G4 Original Android Development] partylikeaninjastar:
Installed and boots with T-Mobile H811 with no issue. I won't be doing any further testing just yet as I'm trying to get a feel for my battery on the stock kernel before I try others.

Only odd thing is flashing it via Flashify seems to have removed SuperSU.
[G4 Original Android Development] Eddiekool12:
I will be glad to test your kernel out :)
[G4 Original Android Development] AndroidGX:
Thanks for the confirmation! I go add this info into first post :good::highfive:
[G4 Original Android Development] jamesd1085:
I have been able to get all h815 kernels to boot on my h811 but it seems to break wifi calling...hopefully others can confirm and possibly small difference can be found so h811 can have custom kernel that fully works...all other features seem fine...any one have any ideas...possibly ramdisk difference?
[G4 Original Android Development] AndroidGX:
I just downloaded yesterday H811 latest M source, and latest boot image from latest available H811 firmware (I think), so I will make soon a fully based H811 work for more stability (and hopefully fix all various bugs encountered in H815 kernels).

I will PM you for beta testing purpose once it will be ready :good: if confirmed working well, so I will do a dedicated thread in T-Mobile version :highfive:

I'm getting corrupt SD card with this. Seems to happen with all the custom kernels I try. Wonder if I'm doing something wrong... 128gb card
[G4 Original Android Development] AndroidGX:
Maybe an incompatible/bad sdcard ? did you tried with another one ?
[G4 Original Android Development] gz5ztg:
But it works just fine with stock boot? and I can take it out and plug it into my Mac and it shows as exfat and read/write just fine?
[G4 Original Android Development] AndroidGX:
With which stock kernel firmware version exactly? 20e?
[G4 Original Android Development] gz5ztg:
20d from the LG-H81520D-Flashable.Boot.zip file available in the other forum. If I flash that then sd card works fine. I try to flash this kernel followed by BETA-SuperSU-v2.67-20160121175247.zip for SU access and upon next boot I get the corrupt SD card message. It is a Sandisk Ultra 128GB card and I am certain it is fine as it works on stock and in my Mac with no issues. it is entirely possible I am doing soemthing wrong :)

Tonight I will try a brand new fresh install of stock or maybe Genisys and try this kernel again. I have to wait until 7pm though as I foolishly reset my Google password 3 days ago and now have to wait 72h before factory resetting the device :)
[G4 Original Android Development] AndroidGX:
Did you tried with some of my previous versions to confirm? but as you said, your problem seems to happens in every custom kernels for G4, so it is really weird :eek:

Yet I have no idea otherwise, seems like other people looks not having your issue with 64GB+ sdcards :(
[G4 Original Android Development] johnny8910:
No problems for me with 64gb sd card on 1.2.1 with v20d
[G4 Original Android Development] Snah:
No problems here either. 64 GB Samsung card, 20D, Xposed and 1.22 of the Kernel.

[G4 Original Android Development] fishman0919:
Is this for the h811?

The title shows h811 but the OP shows For h815 only and download shows h815... just wondering.
[G4 Original Android Development] AndroidGX:
You are right, finally the best way is to remove that, because anyway it has some bugs and is not fully designed for H811, but H815.

The kernel can be flashed in H811 but some bugs may appear since it's not based from H811 20i source, but H815 one.

To avoid confusion, I prefer to remove this info from first post and title :good:

I'm currently working in a full beta version for H811, for now [MENTION=4992265]jamesd1085[/MENTION] is testing it, but I'm not a fan of "blind development" since I don't own the device :cyclops:

Makefile: optimize gcc toolchain for big.LITTLE system

ramdisk: fix init.d permissions

N-JoYz! :cool:
[G4 Original Android Development] johnny8910:
Great work.

Downloading now ?
[G4 Original Android Development] Snah:
Using your Kernel since som weeks. Thanks for your work!

Got one suggestion for the installation instructions. Every time I flash the kernel root is removed. Wouldn't it be good to add as last point: "If you had SuperSU installed before flashing the kernel you must flash it again to get root."? Thus, flash kernel, reboot, flash SuperSU, reboot. Think it would help newcomers to the kernel world.

[Written by my thumbs on a state-of-the-art Nokia 3110.]
[G4 Original Android Development] AndroidGX:
Good suggestion, I prefer to keep clean the kernel flashing procedure but I go add it into first post in installation procedure steps :good:

*edit* : better! just added a FAQ section into first post ;)
[G4 Original Android Development] AndroidGX:
Just made a public beta for H811, you guys can test it HERE. (of course, don't forget to report! :highfive:)

This v1.0.0 has exact same features of v1.2.3 H815, but fully based from H811 20i latest M source + 20i ramdisk :cowboy:

[G4 Original Android Development] johnny8910:
Maybe Im missing something, I don't have a problem with flashing this kernel and loosing SU?

Even on the latest 1.2.3
[G4 Original Android Development] Snah:
I know some people don't and don't know why. A lot of people do however. What's your setup? I have 20d, SuperSU 2.67, Xposed 80 and 1.23 of the Kernel (had to reroot). What's yours?

[Written by my thumbs on a state-of-the-art Nokia 3110.]
[G4 Original Android Development] johnny8910:
LG V20d, no exposed and SU 2.67
[G4 Original Android Development] hairycousin:
Similar to you: 20D, Xposed 80, SuperSU 2.67, Kernel 1.23. I'm using Genisys 3.7 ROM with Tweaks box and root is all OK. This combination of various objects has really made my G4 experience most enjoyable.

I went ahead and flashed the new H811 version for testing over this weekend. Just want to say that I lost root again and had to reflash SuperSU.
[G4 Original Android Development] AndroidGX:
Thanks for the report.

About losing root, this is normal (you can check FAQ for more information, which I just re-edited) :good:

Otherwise, is the kernel perfect ? no bugs ? what about battery ? (better then stock?) etc :highfive:

I recently uploaded a new version, I don't know if you have the latest beta, please download it just in case to be sure :cowboy:

thank you in advance

[G4 Original Android Development] fishman0919:
So far so good... After first boot, reboot and re-installing SuperSU... it took a bit for the phone settle down but then became very smooth and responsive. Battery life seems a bit better for the day... my phone is norm about 80-85% at this time of day and I'm still at 91% and again the phone seems even more smooth and responsive. No bugs or any noticeable abnormal behavior to report.

Thank You again for your work... it's nice to see kernel dev'ing for the h811... especially when you don't have one.
[G4 Original Android Development] Steve125:
Running 1.0 on my h-811. So far no issues. Thank you AndroidGX!

UPDATE

★ UPDATE ★ :​

19.02.2016

: v1.2.4 released.

Add USB fast charge (but disabled as default)

Add KCAL post-processing driver

I finally decided to add those two known and great features (which I didn't want at the beginning, because they are much useful and does not affect battery) :good::D

To enable USB fast charge, you can use Kernel Adiutor or your favorite kernel control app (also for KCAL).

I decided to keep it disable as default, but it may be useful in some situations (GPS in car, or at work for better fast charging, etc). If everything is already fine for you, then just don't enable it.

Enjoy! :highfive:
[G4 Original Android Development] ImandiX:
Hi all! I don't know what has happening, but now suddenly my battery drain very fast, and when i check with Root Explorer in \system\bin\ i can see that logd file is still there? Did you not delete the file in the previous version? Or do i have missed something? I had over 6 h screen time and 32 hours standby time and after i charged the phone, now it's suddenly drain very fast :(?
[G4 Original Android Development] Hoffmanns:
I have logd file in my phone too :) but battery is best :good:
[G4 Original Android Development] AndroidGX:
Thanks Hubert P for your donation! :highfive: appreciated :good:

I think all G4 stock roms/firmwares have this file as default anyway, even if logd is properly disabled.

I just tried to delete this file via Root Explorer and rebooted, no more logd file, so in reality, it's correctly disabled by the kernel :good:
[G4 Original Android Development] AndroidGX:

cpufreq: governor: Be friendly towards latency-sensitive bursty workloads

[G4 Original Android Development] chavocarlos:
Hello [MENTION=2687701]AndroidGX[/MENTION], thanks for your great kernel, I have a doubt, USB Fast charge feature increase the charge rate only when phone is connected using USB port, not when using the wall, right? Sorry my dumb question ;P
[G4 Original Android Development] AndroidGX:
Exactly :cowboy:

But as precised before, don't forget to activate this tweak via kernel adiutor for example :good:
[G4 Original Android Development] Buckycasuals:
Thanks for the kernel. Few minor problems:

1. I've noticed that bringing down the screen brightness to 15% doesn't stick when the screen goes off. Mostly, it comes back to 28%.

2. Could you add auto-root in the kernel? It will help avoid the hassle of going back to recovery to flash SuperSU.

Every other works as intended.

Any idea why i can't turn on the stock Thermald with kernel auditor?
[G4 Original Android Development] ixtis:
For me brightness stay on 15%. No problem.

Sent from my LG-H815
[G4 Original Android Development] AndroidGX:
No problem for me me also. When you do that, are you sure that auto brightness is unticked ? because otherwise yeah, it will comes back with auto once turning ON screen after :good:

Anyway, definitely not kernel related.

As stated into first post, I will not. But rhere is already elemental things to still get root working if root is in system.

If your root is "system-less", then you will have to always re-flash SuperSU 2.6x after flashing the kernel. This method is the same for every other kernels here. On Imperium kernel, slim80 directly integrated supersu flashable zip into his kernel zip and in flashing procedure, but I don't like this because if you prefer to (for some reason) stay on an exact supersu version, flashing his kernel will override it. That's why I recommand to anyone to stuck with supersu 2.52, which is the only latest real proper system partition installing mode, so no more root problems after switching in my kernel versions :highfive:

This part is also described into FAQ from first post ;)

I can switch it ON without any problem here, and it seems to stay :good:
[G4 Original Android Development] Snah:
1. This works for me, no problems.

2. I also have this happening, since I use the newest version of SuperSU. My perfect solution is to add a queue of things to flash in a flashing app. I use TWRP but there are several other. First in queue, I of course put the kernel. Then SuperSU and tell TWRP to use recovery. When it goes to recovery both are automatically flashed and the phone restarted. Easier than ever!

But still just remove facebook and messenger you will see tremendous battery gain!!
[G4 Original Android Development] AndroidGX:
Depends of everyones usage.

If for exemple I open a white page without doing anything and let the phone stand, I think I will be able to reach at least a very nice 500+ hours of screen ON time :laugh: but does it have any sense ? I guess not :o

For me, giving screen ON time is nonsense without detailing your activity :good:

[Galaxy Note 10.1 Q&A, Help & Troubleshooting] DrEcosse:
Since I upgraded my PC to Windows 10, I've been unable to get a connection via USB. I've tried many things following several hours of research/trial and error but not managed to get anything to work.

I do have a Windows 7 Ultimate partition as well as Windows 10 but even that is unsuccessful.
