Gents,
I need your help about "kernel", as I know when installing Android I need the folder named Android and the data.img.
But the kernel what is that?
Thanks for reading and more for helping.
The kernel is the core of the Android OS. Windows too runs on a kernel. Every build already includes one, and usually the most up-to-date or stable version, so you shouldn't have to worry about it, unless you want to update your kernel some time in the future.
I've been running Android for several months now and I've not updated the kernel once.
Still there is somthing to say
First I want to thank you for giving me some of your time.
The answer is clear, but why there is update always (now is 8.6)?
and what the kernel is including, is it the same of Android folder?
I hope I will find some more time.

The reason that the kernels are updated alot is that the people who build the kernels find flaws in them through testing them, and through the feedback they recieve here on XDA.
Then they work to try and find ways to fix those flaws. Sometimes in fixing one flaw, a new one emerges. Generally it is a good idea to use the latest version of whatever kernel came with the build.

Hey,
I've just recently started Android development and I'm keen to learn as much as I can about the whole system, not just about SDK app development. As such I'm interested in attempting to build my own ROM completely from scratch. I've downloaded the Android Source (and Galaxy S source) and would like to try my luck.
First I've been mucking around creating custom ROMs with the emulator, moving apps from the Galaxy S ROM I dumped from my device onto the stock emulator ROM and testing things out.
Anyway I'm at the point where I'm wondering if it's possible to flash the stock emulator ROM onto a Galaxy S phone? I know the Galaxy S source includes a lot of device specific stuff however I'm not interested in getting the camera, bluetooth or anything hardware specific working just yet.
If I flash a ROM with a stock kernel, drivers etc. onto my phone will it work? Has anyone done this? Will it just brick my phone?
Any help would be appreciated.
Cheers,
Ben
Anyone?
Also, I know people have flashed AOSP ROMs on other phones, does anyone know if they required modifications or whether they are in fact stock ROMs?
nje, can't work. why?
1) different bootloaders
2) different partition layout
3) different (kernel)drivers
4) different vendor setup
etc.
it is possible to flash the emulator image onto a dev device (dream/sapphire) but even then a lot will not work properly!
if you want to learn about the android architecture you should start with building a kernel (there is already a thread about that here) and playing around with stuff like the (file)system and utilities...
Thanks jodue.
Yeah my long term intentions were definitely to build the Galaxy S kernel and any necessary libraries and drivers specifically necessary for the apps I decide to include in a custom ROM.
I was hoping that I'd be able to start out by tweaking a minimalistic/generic ROM (the AOSP default ROM) on my Galaxy S. However, as you've pointed out I'll have to start out with the kernel and all the device specific stuff first.
I've got quite a bit of information on building an Android/linux kernel both from the thread you mentioned and also the official AOSP page. However information on putting together a complete working ROM seems a bit sparse. Does anyone know where I can find some information on the topic?
I'm also curious to learn about the list of things jodue mentioned i.e. Android bootloaders, partition layouts and drivers (generic and Galaxy S specific). I assume detailed information about particular devices and drivers probably isn't available but if anyone even knows where I can learn detailed information about default AOSP ROMs I'd be extremely interested know.
I still use my Nexus 4 happily and recently started modding the kernel a bit.
This led me to the question in the first hand, because it is possible to upgrade minor versions (3.4.0 -> 3.4.105)
The thing is, N4 uses google_msm 3.4 sources
shamu is pretty new, uses google_msm too but 3.10
I've tried by bluntly downloading shamu's kernel source, placing mako_defconfig in arch/arm/configs and updating the defconfig with make menuconfig.
As expected didn't work out, but i'm just a little modder cherry-picking stuff i'd like to have, so in reality i have no clue how to archieve that, or if it is even possible with some modifications.
I've also tried with the standard 3.18 Linux kernel too before, but got the same expected result.
Did someone actually tried this and got a bit further, is this something simply not posiible or too much work to get it going?
Hey guys,
I'm just looking for someone to point me in the right direction. Basically, my school has this web portal logon thing called Cloudpath (formerly xpressconnect) that requires you to log on to the portal's network in order to follow the instructions in your web browser for your specific OS. The problem arises with Android. It requires you to download an app, which does all the nitty gritty certificate installation and configuration for you. However, whenever I try this on a CUSTOM ROM (LOS-based and DU), I end up in a connecting loop. I never get connected to the secured network even though the certs appear to be installed correctly. I've tried using the app and doing it manually by downloading the certs myself. This only occurs on custom nougat roms, but works on stock MM (I haven't tried MM roms, because I want nougat).
As far as I know this problem only affects this phone after I install the rom and OpenGapps. Some of my peers have LOS and have gotten it to work, so I'm the only one, and the tech staff have no idea what to do. I don't have the log file on me, but if you need it, I can post it (they're pretty long, but seem to be detailed up until the connection part which just flops between CONNECTED and DISCONNECTED).
Is this a problem with the modem or the roms themselves? I was going to wait until the nougat kernel blobs got integrated to LOS, before trying again as I don't want to use the experimental build because it's a month old now. This problem has been around since at least January of this year. If there is a non-los based nougat rom, I would be glad to try that too. otherwise, I'm at a loss and I need some direction.
Any help is appreciated!
Seeings as how all of our Nougat ROMs are a mixed bag of partial MM and part Nougat still, and all custom ROM's for the MXPE use LoS's device tree, I am thinking this is a ROM issue, probably with some binary blob we don't have yet. The kernel source just released a few weeks ago, give it time and custom ROM's will get better (we think), and if the MXPE ever gets official Nougat, we will probably have better binary blobs too.
If it works on stock Marshmallow, it obviously isn't a radio thing, because your Nougat ROM's use the same radio firmware.
I don't have much else to say, but I would try a custom Marshmallow ROM and see if it works... if it fails as well, the problem is something in the LoS core device tree and it will need some developer's special attention (good luck with that, since we are considered to have a stable device tree it takes some work to get it changed), but if it works, chances are good that once custom Nougat ROMs get updated more it will likely work.
In a last ditch effort. I tried flashing the experimental build after posting this article, and it actually works! Now, this isn't the ideal situation given that there are some bugs (that I haven't run into yet) and that this build is a month old now. But for now, I'm satisfied. I just hope these blobs get integrated to official LOS soon.
Progress on that is here: https://review.lineageos.org/#/q/project:LineageOS/android_device_motorola_clark
If there are any roms out there that are considered stable and have these implemented now, I would appreciate it, otherwise, I think I'll be set for a little while. Thanks for your help!
I don't know if anyone knows about or tested the Carbon ROM build on July, 2017 which I found. Here's the link-
https://get.carbonrom.org/device-mocha.html
Please enlighten me if this is a fake website and fake custom ROM for Mipad(mocha).
it's legit and official site there.
Carbon Rom is Real ..... Not Fake!!!!!!!
I'm using it for past one week . working great

Can u review the ROM in details?
Like Installation process, Android version, Pros and Cons,Stability, battery life,Performance and smooth operations, etc..

I wouldn't use it yet. It was a test build, there are some broken stuff in it. Official build (built by servers) need some extra work, because the device tree/vendor needs to work without changes to the source code itself. This is not possible with our current trees (highwaystar's work), and so there are some issues with that build. Primarily, the camera is broken, because SELinux is enforcing. I've fixed it my personal builds, but now there are some issues with webview crashing. This is why I refrained from making a thread here. Once it's 100% stable, I will make a thread here.
Feel free to use it but don't complain when you realize some things are broken.

Thanks for the feedback. I am using BDITA ROM latest version for over 6 months, although on KitKat but its the safest and most stable ROM I found for our MIPAD. Battery life,performance and ROM stability are 3 important things I look for in any ROM and BDITA serves me well.
I will wait more until I find a ROM which can replace BDITA
This is a question for all the devs here.
Ive been a long time member, mostly lurking. I use to compile windows mobile roms for my own use.
Im interested in trying to build my own custom stock(ish) rom and kernel.
I know it wont be easy and will most likely fail multiple times or even brick my phone completely.
I have the sm-g935w8 version and currently on 8.0 stock root.
My goal would be a custom rom possibly tw with stuff i manully remove and configure i would also make a kernel ..possibly..ive compiled one a long time ago for a linux build. But as for kernel id just like to play around see what is available
Im not looking for the step by step but some information on where to begin and what software ill need.
Also has samsung released latest source code?
Thanks
