Hi everyone, I have been wrangling with this for several days now. Despite some oddities and a syntax error in the kernel source code, I have successfully compiled a working cifs kernel module for the V10. As far as I know this module can only be used with livlogik's kernel, but it does not matter whether or not you are on LP or MM. Unfortunately, I do not think I can compile one for the stock kernel, as android kernels typically require modules to be signed, and I haven't been able to find signing keys for LG's kernels (if you have them let me know and I will try).
All credits go to livlogik for the kernel, give him a "Thanks" :victory:
Enjoy!
(Mods feel free to move this to dev section if you feel it is necessary)

Hi there,
Now, I understand that there's a thread or two and a few web pages directed at compiling Android and its kernel from source.
However, the thread in question is months old, and didn't fully explain the process.
As for the web pages, they are mostly outdated and don't include enough information, not to mention desire specific instructions.
I think that, properly explained, building Android shouldn't be daunting, and everyone should be able to attempt it, if they wanted to.
So, I hope to compose a comprehensive guide on how to do just that.
The problem is that I myself have not been able to put enough instructions together to be able to complete a build. And there is no point digging up old threads.
So, If anyone who knows the ropes (that is, compiling android and a kernel from source) would be willing to lead the way, I'd happily turn it into an easy to understand guide.

I followed this guide here and successfully compiled a modified HTC Kernel and I had very little Linux and Android experience.
Obviously instead of cloning the Cyanogen git, you just use the gits you wish to compile

Thanks for the link
Though i don't fully understand the whole 'git' thing. Where do i find them? And how to i know which ones are the ones i want to use?
Josh
EDIT: Also, how do you 'edit' the kernel (i imagine it is somewhat like make menuconfig?). Also:
- Are these sense kernels?
- How do you add modules like OC and UV?

A git is a repository for source code, developers upload their source code there and can commit changes. The commit can allow descriptions of what was changed and also details the files changed.
The git system allows other people to add to the source if they have permission, or allows others to read the changes and download the source code.
Git links are usually posted by people who release software, as Android is GPL licensed so people have to release their source code if they're distributing their work.
Editing the kernel, take a look into the git and the commits and it will show you which files were changed and how exactly they were changed. That will give you the best understanding.
UV/OC is done by changing the acpu table in the architectures files and changing the minimum/maximum voltage figures in the board_bravo.c file.
The Cyanogen kernels are not Sense kernels no, it's a modified Google Kernel.
Thanks for the explanation. I followed the guide and built the rom, and it works (always a plus )
Now, the next thing is the kernel. How do I build a kernel with the CM tweaks integrated? I understand that all i would be doing is rebuilding the same one that is already installed, but im doing it to learn.
So, if i synced the GIT, does that include the CyanogenMOD kernel source? If it does, where is it and how do i rebuild it. If not, where do i find it?
Thanks,
Josh.
Has anyone built the cifs.ko module for the 2.6.32.15-g59b9e50 kernel? I did some digging around here, found some copies, but they seem to be different versions and aren't loading.
If I should be using a different kernel, please recommend one... I am using OMJ's ROM.
I found instructions for building a kernel, but the kernel source code on HTC's Developer site is for 2.6.32.15-g746f4f0. Is this newer than g59b9e50?
Long story short, I'm trying to get CIFS working...
Thanks!
SGP512 Kernel, first attempt since I just got the device yesterday.
- close to stock
- disabled a few modules which are rather not going to be used
- disabled debug
- integrated wlan driver & configured so that it loads properly
- integrated exFAT
Instructions:
- unzip contents, copy over the modules to /system/lib/modules (remember to set the correct permissions)
- reboot into bootloader & flash the kernel
Code:
fastboot -i 0x0fce flash boot boot.img
fastboot -i 0x0fce reboot
Download binaries: https://drive.google.com/file/d/0B8rpJsF4EG0YMFNHYWZhSHQ5VW8
source
Er... nice that someone starts developing for this device... but:
- what is wrong with the stock WiFi driver? I don't see any problems...
- exFAT is already integrated, no need of special kernel...
Doesn't seem very flash-worthy
I would really appriciate a custom kernel for the Tablet so that we can undervolt the cpu and change frequencies and governors.
But wouldn`t it be the best and easiest way to port (of course with the approval of doomlord) his already existing doomkernel from the Z2 phone?

You won't be able to use the stock modules if you start messing too deep with the kernel & there is no in-kernel (3.4.0) driver for the bcm4339 which the Z2 uses, unless you want to mess with the brcmfmac driver.
Try using the compiled kernel I attached without copying over the associated wifi driver.

You can already change the freqs & governors with tools like PerformanceControl.
The only part which would need coding is UV control & a sysfs interface for it.
I'll do it sooner or later in my free time, but seeing as I don't have much of the latter, you'll surely see the features being implemented by other devs. Or you can code/port it yourself ;]
This post was never intended to being a starting point for developing a kernel for the community. I got the device 2 days ago & prepared my base for private kernel development & since I didn't see any posts related to a kernel base for the Z2 Tablet I wanted to share it so that interested parties could have a good starting point.
It was NEVER intended for end users.

ok, sony released the kernel code on git some time ago, any news with your kernel?

I release this kernel since there were none at that time, at least none integrating the wifi driver & exfat.
Till then, the kernel development for the Z2 tablet took off, so there's no need to keep this post updated.

really? i haven't seen any other kernels around

Uhmmm.... me neither to be honest.
However, it's extremely nice to see people taking part in kernel development. It's not so easy as one thinks. It's a lot of "trial and error" before something can be released to the public.
(patiently awaiting my Z2 tomorrow)
Hi Lads,
Past few days im trying to add the ath9k module to a kernel.
I took the emotion kernel but when i started to make the kernel i constantly receiving errors.
I googled till my eyes burned out of my skull but got no solution. Probably im doing something wrong
Im looking for someone who can build the kernel easily including the ath9k driver.
My purpose is to use Kali Nethunter with the TP-Link WL722N adapter on the Note Edge N915F.
Im so desperate that i want to pay for it. Or maybe a game on steam :highfive:
Please help me out!
Greetings.
Stefjoe
Stefjoe,
I also saw your pm. I know now that you would like that module added to the tblte kernel. Kali Nethunter is not a rom, it is an overlay of sorts. Essentially a chrooted Linux distribution running over the top of your Android phone.
Kali only supports stock roms, or some "CyanogenMod variants", so I could add this to the AOKP kernel for you, but I cannot guarantee that you will have everything you need for this to work. For instance, you are going to need packet injection, module loading and unloading, force modules, etc., etc., much more than just the one item you requested. The note edge is not on the list of supported devices for a reason, it takes much dedication and effort to set it up properly. You would also need to build your custom port of Kali to go on your system. (Unless I am mistaken, no one has made one for the Note Edge yet.)
So, have you already built a working port of kali for your phone?
I say this in the kindest of regards, but if you cannot build the kernel, can you build the kali image?
As a side note, all the tools in Kali Linux are freely available, and you can download them to your phone right now, just not in the glorified package. Having Kali is like having a toolbox. Having a tool box does not make one a mechanic. Having Kali does not make one a pentester, or cacker (unethical hacker) if you are aiming for that.
I am not opposed to you having Kali, I've used it before myself (not on a phone), but in the end, I found Debian to be just as useful, downloading the tools that actually helped me in my job/tasks.
I am just curious if you have already created the kali image you need for the Note Edge phone. In theory, if the only thing you need is a kernel with the above, then it should work with your current kernel, just without that feature. If you have not even made the image yet, then I suspect that you are going to need a lot more than what you asked for.
I hope that makes sense.

Thanks for your reply again! I kinda ported the Nethunter to Note Edge with help from this video on YT ; /watch?v=jhLBJJwB88k
Everything works fine but only the TP-Link WL722N is not working because the kernel does not have this module installed. The adapter takes care of the injection so no worries i guess. I sended u a PM.
I am a certified hacker and i know what Kali Linux is but only missing this tool and it could make my work a lot easier. So i really appreciate if u can do this for me man. Endless thanking

Stefjoe,
I see from your PM that you are not requesting my AKLU kernel, but the TW Emotion Kernel. I can't do that for you.
To build the kernel you need the right source, the source code for the kernel has been updated since r17 ( I think it is r2X? now). That means rolling back through the commits to find the time it was built and working properly and getting that source. It is not as simple as just going straight back to r17, the r17 version you may be using may be anywhere in the commits between r17 and r18.
Then we would need the exact toolchain he/she was building with. He says Linaro 5.1, but which one, 5.1, 5.1.1, 5.1.8? There are several.
Also, I do not build TW kernels. I only build AOSP kernels. I also don't usually build off of someone else's work. I was under the impression you wanted me to add that module to my AKLU kernel instead.
To get that specific kernel built the way you want, I recommend that you ask @Pafcholini to do that for you, since he made it originally.
If you want, I can add that module to my AKLU kernel for you, but I know the rest of the needed kernel items are in there that you need (packet injecting, force module loading, etc.) so I doubt it will work for you. You would also have to switch to AOKP, which may or may not work with your porting guide.
Sorry, but after looking at your full request, I don't think I can help you with what you need.
Hello All,
I am new in the android world, but am fairly experienced on the Linux side of things. I would like to build a loadable kernel module for a specific version of JB (4.2.2_r1) and have some general questions.
As I understand it, the process should be as follows:
Get kernel source for JB, compile kernel, then compile kernel module. Please correct me if I am wrong
I can't seem to find the kernel source for this, can anyone point me to exactly where it is?
Thanks
