Hi Folks,
I'm trying to port B2G to my moto g3. I was referring to this doc (https://developer.mozilla.org/en-US/docs/Archive/B2G_OS/Porting_B2G_OS/basics). However some of the things mentioned in this doc are not clear to me. Could you please help me with the below issue.
I'd like to build the AndroidKernel from source. So where should I include the below lines? Is it in this file?
https://github.com/LineageOS/android_device_motorola_osprey/blob/cm-14.1/rootdir/etc/init.target.rc
HTML:
on early-init
start ueventd
import /init.b2g.rc
Also if I understood correctly. building the kernel from source doesn't require to unpack , edit the init.rc file and repack the kernel from the device. Could you please confirm this?
Thanks,
Arun
Hi Arun,
I totally understand your frustration with this. You'd like to contribute to the Servonk project but first you need to port B2G to your phone or buy a new phone. Since the only other supported phones are the Z3 compact and Nexus 5, both of which are still relatively expensive secondhand, you want to use your Moto G3 which means first porting B2G to it.
So, I think there are two options you have:
1. Port direct from the AOSP code
2. Port from the CM12 code.
As Gerard said in telegram, porting from CM to B2G was never finalised so may actually require more work. However there may actually be more people here who can help you since people seem more familiar with CM than AOSP (in general, I know some people are very knowledgeable in both).
I see you've posted in the AOSP 7.1.1 kernel thread. Unfortunately, for the Servonk project you currently need a Lollipop based build, so 5.x AOSP kernel or CM12.x.
It might be worth asking a mod to move this thread into one of the development sub-forums.
As you know, this is the limit of my knowledge, but I really hope you find some success, if would be great if you could contribute to the Servonk project.
Your last option is to use the desktop build of Servonk, based on Glutin instead of Gonk, but I understand that you really want to get Servonk working on your phone.
Best of luck

A bit of infos before starting this thread. I'm using a Samsung Galaxy S4 Canadian, I have a high end computer(maybe that helps for coding,stuff like that) and I have "medium" knowledge on rooting/flashing,etc. I am a great designer, well for myself, I think i'm good. So I can edit or create icons and themes for new rom!
I say medium, because the only thing I really know about this kind of stuff,is rooting,flashing,installing roms and pretty much that honestly.
I already downloading the Android SDK to test those custom roms i'd like to create. I thought of doing like a couple of guys on here, using the CM Source? and just adding stuff,etc.
--
What i'm looking to do, is creating a rom based of CM for the Galaxy S4 and just in general a little side project for myself and adding some infos in my head; Some may laugh because of the lack of knowledge, but hey! we all started somewhere
I'm asking the community of dev's or just users, do you have some threads or some stuff to download to "Start" this project ?
Some things I should read before, I won't test rom's on my phone as it's a daily phone, i'll use the emulator instead(AVD or SDK) and i'm already searching on how to run it.
If you have any useful youtube videos i'll gladly accept them
I found a tutorial on how to build a rom but for the Nexus 4, I guess it's the same process but different sources ?
I'll search for the sources of Cm for the Galaxy s4 but if anyone reads this thread and knows where to get it, please link me!
Thanks to the community, this may also be useful for other users. Thanks!
Okay, I will help
1st off, let me teach you some basics.
1.) You cannot test roms on the android sdk, the android sdk has nothing to do with roms, its for building apps and java programming. It will not help you with anything if an issue goes wrong in a rom, well only the adb (android debugging bridge) for taking locats.
2.) You cannot compile a rom on windows, only linux, preferably ubuntu. So you need to just download cm11 for your device and extract the rom zip.
I will tell you more later, but its like 1pm here Goodnight
Hi guys, I'm a total noob to android custom roms, so please don't abuse me if I've just asked something very obvious to devs...
Please don't reply giving links to the aosp project, I've already seen them.
Assume I have the system needed to build from the source code.
How do I exactly configure the toolchain for a particular device(say moto g xt1032)?
Do I get configurations with the 9gb download, or do I have to download it separately? And will I be able to successfully compile a working ROM for that device?
I just wanted to know more before diving into my new project.
Hey,
i'm just curious about what the title describes. First of all.
What do i really need:
-kernel sources
-binary blobs (extractable)
-recovery / boot.img (extractable)
Let us just talk about the fairphone 2. Additional to the things mentioned we get the full source code of the OS (which i do not need?).
Where do the difficulties lie? For my understanding we just take the kernel sources, the official cyanogenmod (e.g.) source code, the binary blobs and the recovery / boot.img.
How difficult would it be to port Cyanogenmod to the fairphone 2.
Why is it difficult to port a device with existing (again cyanogenmod just as an example) cyanogenmod to a newer Cyanogenmod (Android) version?
I ask this to estimate/evaluate/judge (don't know the right term) the effort needed to do this. I think i'd be able to do that if i put enough work into it (i "speak" c and java), but i just need some answers.
Especially for example why it is more difficult to port Android 6 instead of Android 5 (which is the currently running Android version)
Thanks!

Has nobody an answer? Just one?
Im specifically interested in why it is more difficult to port e.g. cyanogenmod if there is only an older version of stock android and how important the kernel is? Why do we need kernel sources? Can't one just self-compile a kernel.
Where are the limits if i have a device running 4.2. Why can it possibly run 5.1 but not 6? Is the kernel limiting? Or only the effort to realize such a thing.
Thanks!

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?
Hi, I'm completely new in Android ROM development and want to get into it. I have a Moto G Turbo and a old Moto E 1st gen.
So I had some question regarding Android ROM development. I may sound completely noob which I am, but still if you help me by answering my question or at least referring to some links then I'll be helpful. And please only answer if you are confident about what you are saying.
1> I understand that Android is open source, so basically we can download and build it. What does it take to make that boot on a particular device?
2> Android is based on linux kernel. So we need a kernel source too. I found this, https://github.com/MotorolaMobilityLLC/kernel-msm, is this the kernel source for moto devices? I am confused because I can find only one repository although it must different repositories for different devices.
3> If we have a kernel source for the device, can we build any ROM like AOSP or AOSP-CAF and boot it in our device? If not why?
3> I have a good knowledge of C although I am still learning. How do I start developing or porting ROM? I am specially interested in PURE AOSP.
I don’t know but you might find a lot of tutorials in non-device-specific threads. And I think there’s a guide on how to build lineage 13 for osprey
