ok , have searched on the www with nothing that explains to me (or simple enuff for me to understand ).
question : can anyone tell me why bootloaders are closed source ?
AND this damn carrier radio thats tied/locked/ to firmware/OS.? probably getting my terms mixed up. maybe someone can figure out what i'm asking.

I think it is like with all other proprietary things, the creators don´t want to give they´re rivals
the things they have made for free.

Not all bootloader are closed source.
Chinese's QCOM phones have CAF bootloader with minimum changes.
For example show custom bootloader based on CAF sources: http://github.com/jsr-d10/android_bootable_bootloader_lk
Main menu this bootloader: http://cs5-2.4pda.to/7971817.jpg

I dont think there is one for that as that is not an official version of Android. Very few China based Android phones are supported by AOSP. You may have to start it yourself if you want it. The first thing you will need to do is have the OEM post the kernel source code for the device. This will be your biggest challenge. As most China OEM dont respect the GPL laws

Ok
What if there is no source of kernel? Can I use compiled kernel (3.0.13) from current firmware (4.0.3) or this is impossible?

Without kernel source your kinda out of luck. No that kernel will not work on AOSP as that 4.0.3 is not an official android version. It is a hacked together version. Your best bet would be to sell it and get something that is not a knock off.

Just for fun: wrote to "developer" for sources.

Got to write to the OEM. Only they will be able to release the kernel source. Good luck. Dont hold on to hope though. They are not forced to post kernel source like everyone else.

Don't you know is it real to compile with another kernel for same CPU MT6575?
Found some links to kernel sources for other phones - seems to be working for different devices.
Hey guys,may I know "In order to make a build for your device, you will need a suitably device configuration. Often these are included within the main source download, or are obtained through a method documented by the developers of the ROM." <<<<<where can I get this?
Should be the source code, i guess.

Kernel source code?
I think so.
Where can I find proprietary binaries?
Kernel Source code can be found at www.htcdev.com
After it is released.

And the binaries are located in the source code?I'm asking all this questions because I'm in the midst of developing.And to further understand so that it would be easier for me.
I'm no kernel dev, so i can't answer more than this.
It's ok.
T-mobile Prism II released the kernel source
https://github.com/Prism2/HUAWEI-U8686-Open-Source-U8686-JellyBean-kernel-3.4.0-
That is the link for the source kernel i found with a simple search.
This phone is so close to having a custom rom. Rooted, bootloader unlocked and CWM_recovery has already been made possible on this forum.
So my question is... Where would add the line CONFIG_SWAP=y in that open source kernel.
Is that all that needs to be done to this kernel to enable swap?
I'm sure it simple anyone know?

Its a little more complex

Thanks a lot for that link.
I'm very inexperienced with android and that doesnt look easy. Anyone interested in helping me with this?
So guys finally realme allow us to unlock ( it will take longer time for unlocking as they will review your application than provide a ota which includes the fastboot binary) the bootloader of our realme 2 pro. They have also released the lite version of kernel source ( have not released full kernel source code!).

Guys share your views here after unlocking the bootloader.

What Is Full Kernel Source Code...
Oxygen OS is even better than stock android so...?

It's is mandatory for creating device tree.
I wish they should have given an easy procedure and don't have to wait to unlock our bootloader. Also i dunno know when the development will start or whether we'll get to see any custom roms. Hope the developers will take interest in this phone.
I hope to see development soon

Yeah the procedure is lengthy and complicated! Development will start after releases of full kernel source code.

So without device tree no custom roms can be built.
Then what can be done with lite kernel source?

I dont' know if there's a custom kernel for this device. But you can download the source code form here https://www.nokia.com/phones/en_int/opensource to compile it and add features by yourself.

To compile a kernel from source you can follow this tutorial.
https://forum.xda-developers.com/android/software/ultimate-guide-compile-android-kernel-t2871276
There are more threads, this is an example.
The build number in your screenshot (5_180) tells the number of the kernel version you need to download (i want think so ), in this case is the Nokia3_V5.180.tar.bz2 file.

With having a linux environment you can build a kernel from source reading the guides. Adding features is more difficult because the main reason: this device has mediatek SoC.
