Kernel creation - G4 Q&A, Help & Troubleshooting

I am trying to compile LOS 15.1 for my H815 using @kessaras's G4 files from AOSCP, and it broke during the kernel creation.
I looked at the error, and just commented out the line causing it (inside the g4-common/sepolicy/sysinit.te, it was saying unknown type sysinit), and surprisingly it has carried on building. Are there any chances that this could break my phone permanently when I flash it (assuming the build completes)

Which branch of titan are you using?
If something goes wrong it just soft bricks so you will still have TWRP and download mode.

To be honest, I have no idea. I just took the AOSCP device_lge_g4-common, device_lge_h815 and kernel_lge_msm8992 repos and modified them to point to the correct lineage directories instead of AOSCP

Thanks for confirming this. Its what I thought, and then I came across a forum saying the wrong kernel can hard brick your device

Yea ppl often don't know much about the correct brick terms..
So where do you take the repos from? From our suicide org?
Ensure you checkout the oreo branch! For all repos!
git checkout

I got them from github.com/cypheros/[reponame] and I obtained them by adding them to the local_manifest (with oreo-mr1-release as the revision) and repo syncing

I have now tried building the kernel separately from the main android build process (both with suicide squirrel and official AOSCP sources), and It has finished by dumping the files "Image", "Image.gz" and "Image.gz-dtb" in the arch/arm/arm64/boot folder. Are these the files we are supposed to get (I thought we were supposed to get a zImage file)?
Also, it ended with the errors

@steadfasterX, have I done something obviously wrong?

Don't know about the txt failures. The image.gz-dtb is your zImage. It's the zImage with appended dtb
So does it boot or not?

This kept causing the android build to fail. I'll see if I can build android using that zimage as a prebuilt kernel

FYI moving this to the Help & Troubleshooting section

So...the conclusion I came to was that those are warnings but not errors.
If you have a full ROM build where it works, if you look closely those still appear and then the build continues as normal
If you post the full build log I can see if I can find the problem (I would imagine the error is above those)

Just doing another build - if the error still appears, I'll post the full log. If it doesn't I'll indicate what I tried.
Thank you, appreciate it.

The build failed with the same errors - I pulled off all I could off the terminal. If you have a specific log(s) in mind, please let me know.

I'm really not sure where the build error is arising. I am running a full build make for the H812 UsU using
brunch lineage_h812_usu-userdebug
Thanks again,

Ok so unfortunately I don't think that log goes up high enough (it is the log I am looking for though)
See if you can increase the terminal scroll back size and/or use a method like piping to "tee" to save the output to a file as well

Yep that's exactly what I found
I encountered this error when I began building - it's because Oreo requires an older version of this flex library (or something along those lines)
Run "export LC_ALL=C" before building - that should fix it

Yes, just was about to do that as that seemed to be the recommended solution when I searched the error. Seems it cropped up in newer version of ubuntu-based linux versions.
Sorry I troubled you with this - if I had managed to scroll back far enough in the first place, I might have found it ...
Cheers & Thanks again.

I think I asked enough of these questions when I was learning (including this exact one) so I absolutely don't mind answering them too

will it say no more huge battery drain ?
Quick and dirty compile by me in boot.img format (too tired to hack an update.zip together)
Credit to: Benocharm, and well everyone else who worked on this project... i just compiled it lol
EDIT: Had a lapse and forgot to compile a new wlan module... will reupload after school today
Cant post links yet sooo h**p://w w w .mega upload. c o m/ ? d = 724NZ7Q1
** = tt
remove spaces
Method One Flash: (For those with unlocked SPL)
fastboot flash boot newBoot.img
fastboot reboot
Method Two Flash:
adb push boot.img /sdcard
adb shell
cat /dev/zero > /dev/mtd/mtd2
- write: No space left on device [this is ok, you can ignore]
flash_image boot /sdcard/boot.img
reboot your phone

I think that's very basic that they check it .
I'm more curious about other things that are not so obvious while testing:
volume keys while sleeping, battery usage, g-sensor, correct behavior of the audio jack (audio switches to jack instead of speaker), etc...
'gsm long text > 160 chars' issues can't have anything to do with the kernel used as I see it. That's something of the messaging app and / or the radio RIL used.
Hmm, new kernel to play with... might be the push I needed to try building my own android stuff to learn
Am I missing something with regards to the wlan module sources? Didn't see them so far...
Or am I being stupid (highly likely)

Can anyone point me in the direction of a good write up on how to build a boot.img from this git repo please?im using ubuntu 10.4
so can we use this kernel on the vanilla roms?

Do you have the latest commit? I believe initially there were some missing files. I know when I grabbed the source the first time i had wlan drive compile issues
I applied this to both cronos rom and to superhero rom and both got really sluggish after installing it (I used the boot.img posted among the first posts).

Android Dev. How-To Guide: Compiling the Android/Linux kernel for the Epic Touch 4G

Android Development How-To: Compiling the Android/Linux kernel for the Epic Touch 4G.
NOW INCLUDES ROOT!!!
Introduction: This guide is meant for people who want to get started with android development and don't know where to start. This thread can also be used as a reference place for android development on the et4g. This guide well first be on compiling the android kernel and flashing it to your phone and, I well update it on a regular basis for more complex mods and such to get you familiar with the android platform. If at anytime anyone would like to add more to this, pm me with what you would like to add or fix. Android is an open-source wonderland and I feel like more people should experience the fun of android development. Just remember I am not responsible if you do something stupid and break your phone!
First, we are going to get familiar with the android kernel by compiling a stock build and flashing it with Odin to your et4g.
What you need to download to compile the kernel:
Samsung open-source kernel and platform files. Available at: Samsung Open Source
Type in: Sph-d710 in the search bar in the link and download latest source.
initramfs files (More on this later) (includes cwm, busy box, and of course root! Thanks to chris41g for his help.) Files available at: Initramfs Files
Tool chain for compiling: Available at: Arm-toolchain
Preferably Ubuntu or another Distro. Of Linux running on a partition or Virtual machine.
Step 1: Were going to unzip the source you got from Samsung and take a short look around.
unzip the source and unzip the file that says, “SPH-D710_GB_Kernel.tar.gz” and, open it up. You are now looking at the kernel source for the Epic touch 4g! Okay I well not go over to much whats is here but, I well add a more in depth look in the kernel soon.
Scroll to the bottom of the source and you should see a document that says, "makefile". We are just going to add a name for your stock compile of the kernel, to make it a little more special. Open it and go to where it says Extra version and add your last name ,just make it all lower case letters or it wont compile correctly. When you flash it to your phone, the about phone panel in setting well say: Kernel version: 2.6 [last name you chose] now.
Step 2: Lets get started!
Open terminal in Linux and change your directory to the kernel. You do this by putting,
“cd” and then typing where your kernel source is then hit enter. My terminal looked like this:
cd /home/shane/Desktop/SPH-D710_GB_Kernel
Click to expand...
Click to collapse
Step 3: Tell terminal where your tool chains you downloaded are located.
The kernel is compiled using a tool chain, and the terminal needs to know where the tool chain is to compile. (The tool chain is the folder called “arm-2009q3” )Start by typing this in the terminal:
export CROSS_COMPILE=
Click to expand...
Click to collapse
Then after that put where your tool chain is located. Also when you are entering where it is at, you need to put a “/bin/arm-none-eabi-” at the end of the directory. This shows the terminal that the compiling tools are under the folder bin and starts with arm-none-eabi- and the android compilation adds the last word for the compiler program it needs. (you can see this if you go into the bin folder under the “arm-2009q3 folder.) For adding the tool chain I entered this:
export CROSS_COMPILE=/home/shane/Desktop/arm-2009q3/bin/arm-none-eabi-
Click to expand...
Click to collapse
Then hit enter.
Step 4: Clean the kernel, enter configuration files and make the modules.
Enter this command:
sudo make clean
Click to expand...
Click to collapse
Then enter password and hit enter.
Then it well say something like:
make: /opt/toolchains/arm-2009q3/bin/arm-none-linux-gnueabi-gcc: Command not found
Click to expand...
Click to collapse
IGNORE THIS! It is just a fragment in a configuration file that says the toolchain is not in the default location. But, we changed the tool chain location in step 3 so it well compile correctly.
This cleans up and organizes the kernel for compilation.
Now enter this command in terminal:
make c1_rev05_na_spr_defconfig
Click to expand...
Click to collapse
This is the configuration files for the epic touch 4g and well compile the kernel based off what is in these files.
Now were going to compile all the modules so wifi,vibration... work.
Enter this in terminal:
make modules
Click to expand...
Click to collapse
Step 5: Moving the newly compiled modules to the initramfs/lib/modules folder.
We are now going to move the modules from the newly compiled modules to the initramfs files. So that wifi and vibration well be working in our kernel.
*Initramfs files are the root filesystem of the kernel and does processes the kernel can't do itself while its booting.
You can do this by terminal or by hand. We are just moving the modules to the initramfs to be used when compiling the kernel.
You can type this into terminal (Where it says “Path to initramfs” you need to replace with your own path to the initramfs folder + /lib/modules) :
cp drivers/samsung/j4fs/j4fs.ko Path to initramfs/lib/modules
cp drivers/scsi/scsi_wait_scan.ko Path to initramfs/lib/modules
cp drivers/bluetooth/bthid/bthid.ko Path to initramfs/lib/modules
cp drivers/net/wireless/bcm4330/dhd.ko Path to initramfs/lib/modules
cp drivers/samsung/vibetonz/vibrator.ko Path to initramfs/lib/modules
cp drivers/staging/westbridge/astoria/switch/cyasswitch.ko Path to initramfs/lib/modules
Click to expand...
Click to collapse
This copies the new modules out of the kernel source and puts them in the initramfs/lib/modules folder to be used later.
Now once you enter that press enter.
Step 7: Compiling the android kernel with initramfs.
Type this in terminal:
make -j5 CONFIG_INITRAMFS_SOURCE=Path to initramfs file
Click to expand...
Click to collapse
*Remember to replace the “path to initramfs file” with the path to the initramfs file.
Okay this well take anywhere from 5-15 mins. to compile depending on your system.
Step 8: Were done compiling, lets make something flashable for Odin!
Just type in terminal:
cd arch/arm/boot/
Click to expand...
Click to collapse
Then type:
tar cvf MyKernel.tar zImage
Click to expand...
Click to collapse
This well zip up the zimage (the kernel) you just compiled to something flashable in odin.
If you open up the kernel source file and go to arch/arm/boot you well see the zimage you compiled and, the Mykernel.tar file for Odin. Double check and right click on the zimage and make sure it is around 5-6 MB before flashing.
Step 9: Flashing to your phone.
Go to a windows computer and download Odin.(if you have rooted your phone using zedomax's method you should have it installed already)
Okay now open it up and place the Mykernel.tar file in the PDA section of Odin. Now download the drivers for your phone if you haven't.(I assume you already have.) Then put your phone in download mode (hold volume down button and power button on start up and push volume up button when the warning pops up) Now plug your phone into the computer and make sure “auto-reboot” is the only box checked in Odin. Hit start and your phone well be flashed with a kernel you compiled yourself! If you did this right your phone should start up. If it is stuck in a boot loop, immediately put back in download mode and flash to stock. Link available here to stock files:
http://forum.xda-developers.com/showthread.php?t=1409634
and, try to figure out what you did wrong while compiling and try again!
Good job you have finished!
Step 10: The future and your new phone!
I would like to include more android kernel mods and stuff in the future but, wanted to get this out there to get people familiar with the android compiling process. I want this guide to be something people reference as they start to develop, by using the methods here along with kernel and U.I mods on the platform being implemented in the future. My ultimate goal is to at least know I helped at least one person get into android development so, if I helped you please leave a reply or say thanks. If anyone has ideas to add to the post, please pm me.
Have fun developing!
I'll take this...
and this...

Awesome guide, I am looking forward to giving this a go soon. Just curious but how difficult is the process to include a custom recovery?

It all depends if you wanted to flash a already made custom recovery (cwm) then we would just haved to root the kernel then build and flash the recovery. If you were to make a fully custom recovery with custom functions made by you then it could get a little more tricky but, I am guessing you just mean flashing a custom recovery like cwm. Which is not terribly hard but, not neccesary easy eather depending on how hard it is to obtain root.
I might update the guide in the future. Showing how to do something like this but, I have a few more ideas for the guide before I include this.
You nailed it, I was curious about adding root and CWM(or a variation of it). I am more than content with figuring out what you have posted so far.
Thank you so much. This is absolutely great!

Thanks for this effort. Unfortunately I don't have anything to contribute to your work. I consider myself a budding developer and have been diligently teaching myself to program with the use of some great texts over the last 2 weeks. While I have much to learn this guide and hopefully any additions you make will help me dive nose first into Android development like I've been hoping to for the last couple of years.
I hope you continue to add more into this guide and it becomes a great resource for others like me.
Great Job!

What ROM/Kernel are you using? Have you customzied any values?
Running Codename Android 3.8 no customization except AOKP weather icons and the most recent Faux's kernel 21 but reboots happened on stock kernel as well. I installed the newest kernel to troubleshoot but reboots still occurring
can you please pastebin the logs?? mediafire sucks
I dont have an account there. Is there any other way I could get the logs to you?
Huh i dont think there's a need to register on pastebin.

Compile of CM12.1 error

Hi devs,
I would like to ask you about this problem:
Many times I have compiled succesfully CM ROM (12.1) without any problems. Compiles still the same (same machine, same OS, ...) and since yesterday I get this error. I can not solve it. Please, does anyone know what to do?
Thanks in advance.

Which Java do you build with?
Kitkat: Java 6
Lollipop: Java1.7
Did you try to make clean or clobber or simply "rm -rf out" ?

Using Java 1.7 from time of first build CM 12.1. No problem with it till now. Yes, tried rm -rf out, I got same error after almost 4 hours of building. Sorry, I'm noob, so I don't know, what "make clean" or "clobber" is.

I don't remember the difference of clean and clobber, they delete old files before compiling. But rm rf out does the same, just faster.
Is there other errors above or is it only this error 41?

At your sorce dir, go to vedor/cmsdk, then run:
git reset --hard
After it finishes, go back to your source folder and run:
repo sync
That fixed that exact same error for me. It feels like there's some commit not going through when you simply do a repo sync or something..
Credits where they're due: http://forum.datadevelopement.com/o...building-lollipop-oneplus-one-t2947949/page37
Good luck!
Are you doing forced sync?
These days we sometimes need to
repo sync --forced-sync
@bigtor_gj, @teemo Thanks for the tips, will try ASAP and send a feedback.

No solved for me
Jumping in here - I'm having the same issue building pac for the lg g2. The last successful build I had was on 8/30. Since then, I've gone as far as formatting my build box and reloading ubuntu, then getting a fresh sync - still no success. (I thought it might have been an update to Ubuntu that messed it up)
I'm still looking for a solution as well.

You have given me an idea, I am testing a solution and so far it seems to work, if the compilation ends successfully, the share here.
Unfortunately, git reset --hard and repo sync --force-sync doesn't solved the problem. Still same error on same position of building
What java version is everyone using? Run java -version and put the results here.
Code:
[email protected]:~$ java -version
Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar
java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.15.04.1)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)
I switched from OpenJDK to Oracle's JDK... no difference. I just found the vm I started building on in July, untouched with no updates done. I will resync and try a build on it to see if its an update to one of the packages installed for building that is causing the issue.
...This will take some time...

Thank you for the responses - those are both along the lines of the issue. The first post never mentioned what he deleted tho. The second one is definitely related as I can make it further in my build before failing when I revert that commit, but it still fails.
As few posts as there are online about having this issue, I don't think a commit is directly causing it, otherwise there wouldn't be any successful builds from anyone for the last couple weeks. I think its related to a security update that a few of us did, and most of the devs don't update if its not broken lol. I should know this afternoon...
Edit: I mean its an incompatibility between the changes to cmsdk and some security update I did.

Kernel android-msm-marlin-3.18-pie-qpr2 build failed

Hi all,
I am new to study the android. Right now, I faced a problem that the build would be failed at:
Running extra build command(s):
+ eval python build/buildinfo/buildinfo.py
++ python build/buildinfo/buildinfo.py
python: can't open file 'build/buildinfo/buildinfo.py': [Errno 2] No such file or directory
I noticed that there is a command line in the build.config: "EXTRA_CMDS='python build/buildinfo/buildinfo.py'". How the buildinfo folder be created? How can I solve this problem, thanks.

i can not tell if you 2 are the same person, trying to make this issue look popular or something. ucantseeme was made today and has 1 post, OP has 1 post but account was made a few months ago.
Either way, just now i synced the repo, and built the kernel after removing the "EXTRA_CMDS='python build/buildinfo/buildinfo.py'" line from build.config and it works just fine, booted to it while i am writing this.

Hi Sudoxd,
Thanks for your feedback. I am the creator of this topic and I don't know the "ucantseeme". Currently, I don't solve this compile error issue, but I do successfully to get the kernel image(Image.lz4) where is located at out/android-msm-xxx-xx.xx/private/msm-google/arch/arm64/boot/. I guess the function of buildinfo.py should be only to move the files to the target folder.

The files are all outputted where they are meant to be (/out/android.../dist) already, and the image.lz4 is the normal output. If yours outputs elsewhere I would sync, delete the buildinfo line and rebuild in a new directory and see what happens.
