This will depend on the device and the ROM you want to build, how the sources are stored, etc....
The best place to start is in your device specific forum, as there may be a guide already available for your device.

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.
Below link gives access to open source code for lenovo vibe x3 (x3a40). Can you please make custom rom for my device please?

Sorry mate. I'm sure devs are working on it. But the link you provided is solely for kernel only. There are many device specific codes required to start off with the custom firmware. Guess we'll have to wait at the moment.

Thanks a lot for the reply. Can you please educate me on the device specific codes that are required for a custom rom?

Well to say the truth, I do not know how to put it in words. You see it's the codes that are published by vendors for the device, and some by developer themselves. It contains some proprietary codes mostly in "*.mk" files, some "*.c" files and so on. Device codes can be cloned from similar devices like for our device, we could clone Nexus 5X's source codes for CyanogenMod or for similar ROMs. But still vendor codes for the device is mandatory to get a working device with fewer flaws. And device codes, maybe devs are working on it. We need to be patient until someone comes up...

Here is CM 13 unofficial
Can anyone please tell me how to make CyanogenMod ROM, as nothing is available for my device no device tree, no vendor tree, I only have my smartphone. I tried alot but I didn't found any way to make all materials required to make CyanogenMod ROM.
Device : HTC E9+

Hello,
It isn't possible. You need a kernel, device tree, vendor for building CyanogenMod.

Where can I get them or build them from scratch, I found kernel on htc dev but can I use it make any rom

Hello,
Well you need to bring them up from scratch.
You need to extract blobs from the ROM, update the kernel to make it buildable and booting with CM, device tree from scratch.

Can you provide me step by step quide to do so
I am creating a new android device and want to create a kernel for it, how can I create it? Almost every guide and tutorial suggests to download a kernel source from the device's developer site for the particular device, but what if I want to create a new one?And how can I do it?

First, you need to decide exactly which hardware components to use, then find out which Linux kernel drivers those components require. How the kernel is built and what it contains depends on the hardware in the device.
Really, it would be better to ask this question somewhere else other than XDA, XDA deals with custom development and modifying existing stock firmwares, not with building source code for a device from scratch.

Is there a custom Kernel available for this device which is 3.19 or above.?.?.
If so ...can anyone provide me the link please.?.?.
And if not...does anyone know about porting/compiling kernel for this device.?.?.

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.
