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.

Kernel source availability for The Nokia 3 and other models ?

When is Nokia going to release the kernel source for the Nokia 3 ?
It would be of much help if Nokia will give out the sources for aftermarket development.
If u by any means get hands on it, please kindly share.

Nokia mostly don't give a **** about customers, so no kernel source

Yeah I know but it would be good enough to ask them.
I was previously on a Motorola device(Moto E4-woods) the mtk variant, which we had to ask for kernel source before the released it.
Am currently trying to work on custom Roms for Nokia 3, but going with stock kernel isn't enough.

we can still port roms without kernel source, but we need to find rom with same cpu, gpu and same kernel version.

Blimey! That's a very good sign!
Hopefully they're intact and usable

Indeed, Hoping for great future and development for this device, The cheapest SD 845 yet.

isnt this a security lapse

Lol are you joking? Xiaomi have themselves released the kernel sources. How does that make it a security lapse when they themselves announced this during the phone launch?

Great news! Hope to see LineageOS soon for this phone.

It is rather a question from me, I know mi released the codes but question is can it be used by someone for hacking this phone. I guess it would be more easier for the hackers now.

POCO F1 is not the only phone with it's kernel source released. You will find kernel sources released for many phones by different brands (Sony, Samsung, LG, OnePlus and so many more). The purpose of releasing the source is to accommodate custom ROM and Kernel development by developer community (like XDA) and find out vulnerability (if any) in the process. Any vulnerability found is usually patched in updates. Yes the source can be used to compile a kernel or ROM with malicious code or an app which'd try to exploit the vulnerability but it will only affect those who'd install any such app/kernel/ROM. Now any flashaholic you'd meet will tell you how they'd only install apps from trusted sources and flash ROMs/Kernels available on XDA etc. In nutshell, I don't think trying to hack a phone using kernel source is worth it as it targets very limited people who are cautious enough on what to install on their phones making it more difficult to hack. Any developer can enlighten you more on the issue as I might be totally wrong on the issue too.
P.S. It's because of such source code releases that community like XDA is thriving.

All linux based kernels are open source

Also it is mandatory for OEMs to release kernel sources per GPL license rules.

I got my phone today, waiting for some awesome development..

Thank you everyone for comments :good:. I got my phone today as well

Will only buy it if any rom(i wish for Omni) is built from sources(not ported rom) and officially supports Treble <3
Otherwise simply useless phone for me :X
Would suggest the same for others too

All roms are build from aosp and other sources, this is not 2012 where ported roms exists here. What are you talking about? Also, the phone is launched with 8.1 so it officially supports treble out of the box. You high or what?
Btw: good to see early release of kernel source but on the other hand, the unlocking of bootloader showing me 30 days (720hours). How will I live for 30 days using MIUI?

[kernel][oreo] nubia official kernel source for x

It seems that no one realize the ZTE official account at Github (ztemt) have released the official kernel source for the X.
Here is the source link: https://github.com/ztemt/NX616J_O_kernel
PS: I m not a rom dev so this thread is just aim to let other respective romers know the info

Oh I hope somebody starts working on a ROM! I'm on the verge of sending this back to Geekbuying because I can't get all the google apps to work/notify correctly. Half the time I miss messages and phone calls, which makes this phone unusable!
