Hello everybody,
I'm back on the forums after being away for some time.
In the meantime I got myself my own LG Optimus G to be able to get to effective developing for this device.
My opinion is that this device is a powerfull device with a lot of "still to be unlocked" potential.
Before I bought the LG Optimus G I used the Samsung Galaxy S Plus, which had a very active and good developers which even today still perfectly support this old device.
When that phone launched it contained Android 2.3.6, but today it supports even the Android 4.4.4 builds (unoffical).
One of the most important steps in achieving this goal was to move from the Samsung provided kernel source to the CAF (Code Aurora Forum) based kernel source.
Because I wish the LG Optimus G the same future as my old device, I would like to get busy with bringing up the CAF kernel codebase on the LG Optimus G.
This will be a big project which is why I request fellow developers which are interested in this project to please join and form a development team with a common goal.
What needs to be done is:
- Obtain official LG Optimus G (Android 4.4) kernel sourcecode from: LGE975_G_Kitkat_Android_V20a_Kernel.zip
- Obtain latest CAF Kernel codebase (chipset apq8064) from: msm-5bfc8718998bedfeea1997d83838ffd1981cbf12.tar.gz (Last modification date: 30-06-2014)
- Extract added LGE Specific code and drivers from the official LG kernel source.
- Set-up a team Github with the clean CAF codebase, which all the driver and LG specific code will be added to.
If you're interested in helping with this project please contact me or leave a message over here.
Please no spamming etc.
Greetings PsychoGame
Hello everybody,
A little status update:
At this moment a 2-man team has been formed.
We have a team Github set-up for the development process this team will have.
The github link is: https://github.com/OptimusG-Dev-Team
If you are interested in giving us a helping hand with this project you're more than welcome.
Leave a message in this forum thread or contact me through a PM.
Experience with linux and also with the kernel is of course important.
Greetings PsychoGame
Bravo. Im hopeless in terms of what ever you code ninjas do, just wanted to let you know that i and most likely all in LGOG community greatly value this project. If you haven't already, perhaps PM some kernel devs as this would help in project gaining momentum and improved outcomes.
Happy to see that you're back psycho. Very brilliant idea. I hereby tag some devs to attract their attention. @faust93 @Loller79 , @jollaman999 , @Kevinjoa , @ThatKawaiiGuy , @xboxfanj , @JustinXu , @houstonn
Hey, I don't know much about kernel stuff, I'm learning Java atm so might be able to give tips. Not a lot though.
I don't have the Optimus G anymore (haven't since March), so I won't be able to do a ton, but I can help solve issues if/when needed.

I don't have kernel knowledge that much... I just referenced other dev's kernel sources and fix it to my style.
But thanks for mention to me.
It'll take some time, but I'm sure we get there.
Thank you for tagging some other devs inside this thread so it raises more awareness.
Everybody is welcome to join this project, for example clone the repositories, making changes and contribute.
That's exactly what opensource is all about.
And of course if you're interested in joining the team just send me a PM and I'll bring you up to speed on the progress/process and give you the needed information.
At this moment I'm also in contact with a official LG Developer which hopefully can provide me with some information that will help this porting process as well.

What about @houstonn ? Also I don't have any knowledge about this sort of thing really but I'll ask some other debs around to see if they want to join.

Generally, if you look at the branch of the libEGL_adreno file (using strings or hexedit), you can figure out what tag the OEM used (or branch) and then plop their source over that, then git pull the latest branch on top and fix any conflicts.

Thanks for the information xboxfanj . I never noticed the branch information inside the LibEGL_adreno files.
This also helps a lot with the extraction of the LGE added code as the branch is now as close to the LG used sources.
This keeps the extracted LGE patches as clean as possble to almost only include the LGE added stuff.

No problem. Let me know if you need help. Obviously, I can't test anything, but I should be able to help you get things building.
Oh, i noticed this thread just now.
I can help but i don't have much free time these months.
The idea is interesting from what i've seen, if you want another hand contact me via pm

Today we've updated the proj-kernel repository with fully patched kernel sourcecode.
With a few small 'hacks' we are able to build the j1vd-perf_defconfig to the end.
What remains is getting the updated kernel to boot on the Optimus G boards.
At least the project is moving forward.
Just wanted to give everybody a update on the progress we're making.
Greetings PsychoGame
Here I'm back with some great news for everybody.
Today the kernel which was built using our sourcecode has succesfully booted on stock KK rom from LG.
The next steps we'll be taking will be getting the kernel to work with CM11 as well.
This way I hope we will have a perfectly stable and up-to-date kernel for the Optimus G which will work for Stock as well as CM based roms.

very nice job mate. I think in this step @faust93 can help a lot.
Is this kernel work specific to E975, or will it be compatible with for example Sprint variant LS970?

At the moment it is based off E975 sources so it won't work on ls970 and similar.
Running it on my phone now and it works flawlessly.
Please thank a lot the team that made this possible and xboxfanj who helped with the project.
What's up guys? Is there anything we can help with? any test version or something?
I was checking the display manufacture by entering "dmesg|grep -i panel". But i also find out one thing that the ULPS feature is disabled. I'm wondering if someone can take a look at this feature and maybe enable it in the kernel :laugh: Franco's kernel for Oneplus One already have the ULPS feature enabled.
What is ULPS ?
We need wait Official KitKat release to hope see a Kernel for Find7a...
i m very disapointing by all talented dev on this device and can't see any custom kernel...

I believe the full name is "Ultra-Low Power State".
Since Find 7 and Find 7a are not as popular as other phones, we might need to wait for a while for custom kernel. I'm just hoping that the CM kernel will gets better and better for now
Thx DoomBoss... i think a custom kernel is needed to activate this stuff !

I'm not sure, but If CM devs add it to CM kernel for Find 7 (it is already done pushing the commit for the Oneplus One) then we probably would have it enable in CM ROM or other CM related custom ROM :laugh:
Hello everyone, I am the developer of Despair Kernel on Nexus 6(Shamu) and Sensei Kernel on LG G3(discontinued) and Sensei Kernel on OnePlus One(bacon). I also maintain BrokenOS for Shamu and Bacon.
Now to get to the point, I want to develop a kernel for this device, but I don't have a device to test.
This is where you guys come in handy.
I need a few testers willing to test out the kernel builds to ensure they meet my expectations and requirements prior to creating an official thread and officially announcing support. If you are available to test with me PM me or send me a message on Google Hangouts [email protected]
Iam willing to test your Kernel

Hello guys
I am a little android developer who has succeeded to build LinegeOS 14.1 for Xperia E3 device. As I have seen here, this device never had good developers, ROMs or recoveries; but I want to change that.
I have been starting to work on this device some time ago and I think it will not be too complicated to build a decent Nougat ROM for this device and a good recovery (such as TWRP). Since I do not own this device, I need your help to test everything that I can build from git sources.
I have created a group for this on Telegram:
MOD EDIT: Link Removed
You are free to join, but I prefer that people who joins wants to be a tester. And remember, the more testers there are, the better the development will go.
Reserved for announcements
Hello, nice to see something like this. in which phase is project? REGARDS!!!
Also curious if this project is still alive.
I want to test
Hi @rmnhg,
i got an old T3 from my girlfriend so i can do anything i want with it.
How far is your common efforts here https://github.com/infus38/android_device_sony_seagull ?
I see other Yukon devices have stable LOS 14.1.
Can I check out and compile this repo?
Best Regards
I want a constant base ROM which isn't going to change and will be used as daily driver.
The other ROM should be changeable and it will be for testing purpose...
If anyone owns a solution, please reply with proper guide
Thank You!

I have tried to test it recently and found u need a supported ROM as secondary ROM which do not patch/update vendor image(maybe someone could convert a trebled ROM to non-treble,or solved the problem of vendor partition by remounting or another?)Btw,not all non-treble ROMs are available as secondary ROM and I don't know it exactly,too.(depends on kernel , baseband , building-tree or another?)
More tests and the help from some developers who is interested in it we need,I think.:highfive:
