Develop Bugs

Kernel Development Team

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.

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.

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?

[Rom][6.0.0/5.1.1(Not Sure)][DM][OMNIROM Build Modified][BigPart][Alpha]

Hi And Welcome To a Non-Tested Version of Android 6.0.0 on the xoom (Maybe 5.1.1 Not Sure) But back to the topic
This is mostly 5.1.1 but maybe with new of fixed features (I've never tested it as I said)
Here is how to install (I found this on another area)
1. ROOT YOUR DEVICE
2. Install BigPart TWRP
3. Wipe your system and flash the zip file
Here is the zip file
(I'm having Issues of Attaching The File So Please Wait)

so is this rom 5.1.1 or 6.0? id love to try it out...

I just resurrected my old xoom and converted it to bigpart.
waiting for the zip....

Waiting for test it.

Did you build this rom? If so, how can you not know what version of Android it is?

Just "copy n paste" from "other area" is not very trustworthy... i'm sorry to say.
I would love to have 6.0 on Xoom, but I want it to be wit ha Git Repo or anything and not only an ominous zip file from somewhere...
so please, more information is the key!

Based on this post, I think that, best-case scenario, he just kanged Schischu's 5.1.1 build and maybe themed it to look like 6.0. But I'm betting we never see a zip file.

As with everyone else I am curious to this. [6.0.0/5.1.1(Not Sure)] <--- this seems a little strange. It can only be one Android version. If it's 5.1.1 with some cherry picks and tweaks, that's great but just say.
Also some source would be good so we can establish what it actually is. Upload to androidfilehost or something similar if you can't attach.

P.S OmniRom wanted me to make a rom so perfectly fine

The Download is now available in the downloads tab
here is info
Modified Launcher3
Modified SoundRecorder
Modified PackageInstaller
Android 5.1.1 with tweaks
gapps and super su are not included so please download them

If the OP did not do some coding on our outdated kernel and just synced omnirom sources, or even worse, just replaced some apk's in the flashable zip, all bugs are still there. If you did alter the kernel code you have to apply to GPL and post kernel sources.
I don't mean any disrespect but I kinda have the feeling that you don't have alot of experience with coding. (Please correct me if I'm wrong though) Posting untested software can give inexperienced users alot of problems and could be potential dangerous with our altered partion layout.
This wont have any benefit over Schisu's rom for now so I really have to advise you to wait for updated kernel sources before posting.

Like I said, I don't mean any disrespect my friend. The Xoom needs talented developers but not knowing if your rom is android 6 or 5 raises questions
You should contact the old member of team EOS or Schischu.
Good luck.

Always try to build kernel with source. I think you can't, but you can try.

Please edit the link in OP, its me who miswrote it... : /android_device_xioami_mocha --> /android_device_xiaomi_mocha

You need to fix up SELinux and the init scripts. Taking a shield tablet device tree, renaming things to mocha and changing the fstab isn't enough. As far as I can tell the shieldtablet device tree also has dependency on a shield common tree. There's also no value in creating a new thread each time you push new commits
Our kernel from Xiaomi is also pretty useless without commit history. The device tree is also from shield tablet, not Nexus 9.
We also have a tree for building TWRP with OmniROM that you can compile TWRP 3.0.2.0 with.

What kernel repo is upstream one for tegra android? Like CAF for quallcom.
I've tried to merge xiaomi changes on l4t kernel https://github.com/HighwayStar/android_kernel_xiaomi_mocha
Merged dts files and arch/boot/march-tegra with some required drivers, but still cant boot it. Found somewhere here that l4t kernels is not for android, but for GNU/Linux, but what kernel is for android?
Cyanogenmod's shield kernel?

I used rel-tn8-l-r7-shieldtablet8 to make a start on doing this. You could also use android_kernel_shield from CyanogenMod repo as it comes from the same place. But it will have a lot of extra commits for things not useful for mocha.

Untested, been doing device bring up. That kernel won't work yet anyway it's missing atmel, synaptic and battery firmware. (Plus the code that goes with it)
Some devs have one that gets to recovery but only 1 CPU core can come online and the CPU gets a bit hot. Unfortunately their commit history is hard to follow so I've not had a proper look at it yet

My my...it's been a while since I've seen a cringe-worthy dev thread on XDA. So OP just used the device tree from Nexus 9 (a 64-bit device with a different processor and nothing in common with the Mi Pad other than the fact that they use Nvidia SoCs and are both tablets), unmodified KITKAT kernel sources from Xiaomi (which takes work to make it boot, even on KK) and KITKAT userspace blobs to compile the ROM, and for some reason decided to share it without testing. The 10-post rule is meant to keep such people out of the development sub-forums, but obviously that's not working.
I do not understand why the moderators are allowing this thread to remain open. It's just a thread by a wannabe dev offering a non-bootable ROM that has the potential to brick the devices of many newbies who may decide to try this.
This thread is even more useless than the other "DEVS-ONLY" thread someone else made. Honestly, the entire Mi Pad forum is filled with people who either expect Android 7.1.1 to magically appear on their tabs just because Xiaomi released outdated kernel sources or just wanna create threads like this for the "thanks or whatever". The never ask for ETA rule seems to just float over their heads.
Now to some useful information. I believe, even if we patch the kernel enough for it to theoretically boot cm13, it probably won't, considering the outdated userspace blobs for the Mi Pad. Unless someone has the knowledge to take their tab apart and figure out how to get UART data, it will be virtually impossible for the mi pad kernel to boot any new version of Android. I heard another interesting approach taken by some russian devs at the Xiaomi forums. They've managed to port the kernel from the Nvidia shield (and apparently it's booting). Now this would mean we can use the userspace blobs from the Shield to at least get the ROM booting (most peripherals won't work, but that's step 2). I do not know whether they use GitHub or if they've even open-sourced their work, but now we know that it's possible, so that could be a possible method of approach.
EDIT: LOL. I just read the OP again. The "dev" expects donations to help him work harder. This from a person who posted his way into somehow compiling his first Android build without even having the damn device.

I agree, this device has no development threads. Only 2 give me thanks and here's my donation link threads.
They have indeed used GitHub, but I don't believe they want to share the repo just yet so I won't post it publicly. It has many problems to sort and also sadly, they didn't keep the commit history from Nvidia as it was initialised via zip DL. It does boot to recovery though.

Oh! I didn't realize we were talking about the same person/team. I'd love to start developing for this device. In fact, I'm working on KEXEC-hardboot and Multirom right now, but I'd like to follow what you guys are doing and contribute as much as I can. Is there an IRC channel/IM app you guys use for communication? If so, I'd appreciate it if you could PM the info.

Oh really? My bad... Can I just pull from that kernel-msm repo mentioned in the original post? Or is there a different repo just for Potter?

It looks like the source release for NPN25.137-15 is tagged here:

It's a bit older than the version shipped with my phone but it could work. I'm going to see if I can compile it later.

Man yes let me mention the guy who successfully ​able to build with Alberto's sources. He is @i.snehal.kiran.
He has done this to compile but unfortunately for some reason he doesn't able to get the device to test. His msg is below
basically i have taken addison device tree ...just change the kernel path and defconfig name in boradconfig.mk ..makes it build boot.img
the source provided by motorola on github is full of errors..so use alberto's kernel for addison till you get official kernel from moto

I got as far as getting the LineageOS sources pulled for 14.1, had to do it twice since it was too big for my home directory so I had to create a new volume and run repo sync again. Took forever, but at least I have the OS sources downloaded. Now we're at the point of getting that kernel and setting up a device configuration for our device. Once we get that, then I can see if we can build and flash.

I got as far as getting the LineageOS sources pulled for 14.1, had to do it twice since it was too big for my home directory so I had to create a new volume and run repo sync again.

I want to build Lineage OS (or any other android version) for my galaxy J2 (J200G varient) but the only problem is the vendor tree which I don't know how to build. If any experienced developer can guide me to build the same (vendor tree) then he will get the blessings of those who are still waiting for feeling the stock Android on their J2 ...
Please Devs help me.. I have built only 3 roms yet and that too with all the trees i.e the kernel, vendor and the device trees already available... I can't even find a good document or a video tutorial on youtube to build vendor tree...
But if there is any then please point me to it

PLS JOIN OUR J2 WHATSAPP GROUP

Sources link please.
Can you please provide me all of the sources that you are using to make this ROM. Links to the resources you have been using till now would be good. I am also attempting to make the LineageOS for J200H 3G variant. That way we can test each others ideas out and make a stable LinageOS ROM for J200H 3G variant. Hope you will reply to this message according to the will you have. Thanks either way in advance.

 @izzy12 and all the other devs who are interested in making the ROM or by bug testing the ROM after initial release.

Hey @lzzy12 this is the only documentation i found on net and don't know if it will work or not but you can give a try
https://techstarspace.wordpress.com...extracting-proprietary-files-from-the-device/

Help needed.
@izzy12 , Do you have the source file of j200h? Since you are trying to make a ROM from scratch (According to your methods) can you please provide it to me. I was porting the ROM from LTE to 3G (I was successful)(Yeah i made some changes to convert it) But got into problem. I think your files may help me figure it out. Can you please help me. (If you are trying to make ROM from source file). You may provide me with the link file. Hope you will reply to me.

I am so sorry to inform you that my built of boot.img crashed (It was working but i tried rooting it). It won't even show the Boot logo now. It only displays Samsung Galaxy J2(Startup screen). It is currently hooked in restart loop. So it will take more time to figure this out. Hope you will have patience.
I am currently working on resolving this issue.
.
If any one knows why it is occurring or have been in the same situation please reply. It may help me solve the issue faster. Other files has been already modified, almost 65% work is done....
