Hello, I'm new to sony xperia m2 (d2306) and looking several post and thread it occurred to me to do something lol. Seeing that no rom is 100% stable and that there are no kernel with advanced features, I happened create a kernel based on stock firmware 18.3.1.C.1.13 kitkat.
Achieve up the kernel "Xperia ™ open source archives" with the version already mentioned above.
Come to the point lol
I would like to learn how to modify the kernel or if someone wants to contribute to this project that I have in mind and maybe later form a team for this device.
Amm that lol
(sorry bad English use google translator)

Remember ... stock kernel for now
Before you can modify the kernel, you need to understand how it works, what does it do, what is it for etc. Modifying kernel without knowing anything about it would be a walk in the dark really

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As for the web pages, they are mostly outdated and don't include enough information, not to mention desire specific instructions.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.
Hi,
I'm following the Nexus S Android Development for 6 month now and Rom and Kernel flashing is a a real addiction for me (I flash everyday).
And, since the beginning i want to create my own Rom.
At first, I want to build one from another one (Cyanogen or another).
So, If someone can give me tutos, tools, tips and advices, I'll be very grateful.
Thanks to everybody, waiting for your help.

Hey you know i find myself sharing this exact interest as you. Let's collaborate and learn this Create A ROM Project
Notice to see the motivation to create a new ROM.
How good are your Linux skills? If you want to do it all properly I suggest you try and build your own AOSP ROM first (from the Adroid Open Source Project).
This is the place where Google publishes the Android source code files. Actually the site is fantatic and guides you through the entire process, but it does require you to understand the basics of the maketools in Linux.
Once you've been able to compile the source, you'll actually have a perfect stock ROM version of Android. Then, you can start doing advanced things to it. Add a different Kernel, add apps, install tweak scripts etc etc etc, the options are endless.

Good luck and have fun, because it is

Thank you for your help and advise, i will look into it. I'm a novice concerning linux but i can learn fast.
Thank you again.
oh thats great
Hey guys, I want to install a custom kernel, razrqcom-dev-team kernel, on my XT925 - Carbon ROM(0614) but I dont find any information about how to procede.
I downloaded the repository android_kernel_motorola_msm8960-common(razrqcom-dev-team). Someone has a good instruction or know a good tutorial to share?
My apologies about my poor english
Cheers,
Just to clarify: Are you looking for the pre-compiled kernel or do you want to learn how to build android from source?
If you only want a precompiled kernel, then you shouldn't worry, as the right one is already built in line with the rom you chose.
hello, so i have been in communication with huawei regrading the kernel source. i mentioned the lack of source files for the mate 7 and how its part of the google/android agreement that oems must share all relevant sources for devices that use any part of android. they replied with the usual reply about how they will work hard to resolve this issue and whatnot. the rep did give me a link to the kernel source which i believe is for kitkat but i cant be sure so i hope that someone can verify.
having said that, why cant the kitkat source be used to build for lollipop and marshmallow? im still using a nook hd+ that is running MM......... WHAT??? how is this possible if the only kernel provided was for ICS? anyway, im going to keep poking at them until they either give up the LP/MM sources of they tell me to ****off. so, if anyone can please check out the link i would really appreciate it.
Lollipop Kernel?
Hello there,
I am currently having a One Plus One. I have multi-rom utlity which allows me to have multiple android OS installed.
Currently the cyanogenmod based custom Marshmallow Rom I use (http://forum.xda-developers.com/one...m-kernel-unofficial-cyanogenmod-13-0-t3242700) has switched over to using stable CM branch as their rom base. So this requires using Super SU for root access. Unfortunately Super Su is not compatible with Multirom implementation for OPO.
One suggestion provided was to try building the custom rom from source with user-debug flag. Meanwhile I came across two build.prop values (ro.build.type=userdebug ; persist.sys.root_access=1) which I hoped would enable inbuilt superuser without rebuilding the rom from source but they did not work.
So for now, there seems to be no other way around building from source ( I wanted to avoid this as much as possible because I have a very slow Internet access downloading 30 GB or so for the ROM alone will take a month for me).
So here are my 2 questions:
1> The rom developer in the thread mentioned in 2nd para, talks about 2 source (Kernel and the rest). When I looked at the manifest, they talk about replacing something. So does this mean I need to download the cyanogenmod sources as well or does repo sync take care of that automatically ?
2> I assume the kernel and rom need to be built separately. Can the "userdebug" mode be enabled only by rebuilding the kernel and then placing it with rest of the rom build zip provided by the developer to avoid rebuilding the whole rom ? or better yet flash the my userdebug kernel again after the normal rom installation ?
Thanks In Advance
