Getting F2FS in the last KitKat version - Xperia Z2 Q&A, Help & Troubleshooting

Hello, I wanted to downgrade to KitKat to get F2FS, but, I found out that the only kernel that supported it was the AndroPlus Kernel in version 32, and, unfortunetly, there are no archives of this version.
Where can I get it? Does someone have a mirror of it? If none of this is possible, how can I build it from the source that AndroPlus provided?
Best regards.

need Dorimanx V10 kernel

Hello.
I want to dual boot my s2 i9100 with cm-12.1 and cm-10.
I have those ROMs.
but I can't find the "Kernel_Dorimanx-V10.44v004-COMP-mv3-[10-30]-[29-09]-JB-SGII-PWR-CORE.zip" needed for it.
All the links are dead including this one http://d-h.st/zf3O
please provide me this file if anybody have it or tell me alternate way to dual boot.
AFAIK, the specific kernel build is not not required for dualboot (I don't have much experience with dualboot though). Any recent build from the 10.X branch should be fine (as they are all maliv3 patched).

Android kernel how to make compatible with higher os? (+Where can I find the patch?)

Hello, I'm newbie dev trying to build CM13 for Lenovo Phab plus.
I think I'm almost finished with device and vendor, but I cannot figure it out what to do with kernel.
The circumstance is,
I have a stock kernel source which runs in 5.1.1 LP, with version of 3.10.49.
What I want is to make kernel compatible with 6.0.1.
I already know that linux kernel version doesn't have to be exactly same with new Android OS versions and I can just make a few patches in order to run kernel in higher OS.
So I googled and studied(?) for 2-3weeks, but got not many useful informations and I still cannot figure out where to find required patches for 6.0.1 .
So here's what I am not sure about.
1. I found that I can either upstream, merge, cherry-pick kernel sources from higher OS. For instance, if I merge kernel patches (starting from 3.10.50 to 3.18 step by step) and check if the kernel compiles successfully, is this a right thing to do? I am confused whether merging or cherry-picking is required for my situation.
2. I see lots of commits when comparing with other kernel sources in github. How do you find those kinds of patches? -> just keep compiling kernel and if error comes out->search->commit
Always this pattern goes again and again till boot properly?
3. i'm quite curious with backports. What i know is that "backports" are the files which is compatible for lower version kernels. For example, backported audio driver originally based on 4.9 can be used in kernels with version below 4.9. Is it right?
4. If there is an useful links, anything could be helped a lot.
THANKS IN ADVANCE.

What Steps Do You Take To Upgrade A Kernel?

So the phone manufacturer has provided kernel source and lets assume that it compiles and deploys fine.
What are the steps to upgrade the kernel to a newer version?
Lots of threads that I read suggest looking for another kernel that is based on a similar device and using that.
However, what happens if there is no similar device?
What steps do you take to upgrade a kernel in this case?
Would I just find the equivalent base in the android kernel source and git diff and patch each commit until I got to the version I wanted then try to fix any compile errors?
I can't seem to find a thread with the actual fine details of the kernel upgrade process.
I didn't get round to upgrading my kernel.
Does anyone have a developers guide on the steps to update your kernel source code?

Question about kernel, no noobs please :D

Hi, this is my first post on xda, but i was reading it about 4 years and now i have unusuall question:
I have phone - samsung callisto (GT-I5510) with cyanogenmod 10.2 rom (android 4.3.1), and kernel sources are available for it, but only below 2.6.35.7 since phone is ancient. This is "latest" and probably "fastest" android phone with qwerty keyboard (not including this unrootable new blackberrys), so i think that it would be nice idea to deploy lightweight kali linux nethunter installation for hacking purpouses. I had some problems with oficial installer, and i had to modify it to allow install on device with such small /system partition, but the problem is that chrooting to Kali Roling is not working, becouse minimal kernel version needed is 3.2.*.*
Question is: Can i somehow "update" kernel sources of this device, so i can build 3.2.*.* kernel? I have much free time and even more determination to do this.

Compatibility problems and custom kernel

Hi!
I've got a really old and "rare" Archos phone and I'm trying to upgrade it but I have a bunch of questions.
-> is there a list of which android versions can support which old kernels? (like can I get Nougat on a 3.4.5 kernel version?)
-> if I want a new kernel, how am I supposed to choose it? I've found the Mediatek kernel for my phone model but I need a kernel based on a newer version. Is there a tuto that explains how to modify a kernel to support a certain device?
-> can I upgrate my existing kernel without needing to go find another? or can I adapt a newer android version to my old kernel?
Basically, there is no custom ROM for my model and I try to build one and am more and more confused about where to start. (Like if I start with Nougat but my kernel doesn't support it that'll be a bit of a time waste.)
Thanks for your answer!
With regards to a list look inside here.
