Do you mean compile a kernel from source?
There are a bunch of tutorials on this, here is a very good one.

Use that thread for compiling and modifying a kernel, that is the hardest part. Once you get that part, you can start to mess with UI stuff like launcher and themes and stuff.

I have Ubuntu installed on my TF701, and I'd like to attempt to compile android kernels on the device itself. I would think/hope that this would eliminate the need for a cross-compiling setup.
I'm also interested in compiling general linux kernels for use with ubuntu/debian on the device.
Has anyone done this before? Any pitfalls? Any suggested reading?
This should be possible, but it will be much slower than on a PC. Do you really want to wait hours for a compiled kernel?
If you are able to install the Android SDK on a PC, you are about one command line away from cross-compiling a kernel.

No - the general consensus seems to be that optimizing the kernel for speed is worse than optimizing for size, so I didn't try.

Since you are talking about size, have you looked into the bionic patch? It is supposed to reduce the kernel's binary size quite a bit by removing and optimizing c headers in the source code...

I don't know much about it and it is the reason that I am asking, haha... All I know is that it will find the unused c headers and compiling the source and create a smaller binary. For some reason, it also speed up your device. Nexus forum is discussing a lot between devs. It is just over my head atm and trying to understand it as much as I can... I may not understand it correctly and thanks for your time with a noob's question like this, haha...:laugh:

I would love to but I ran across this topic when I built my toolchain for tegra 3 t33 about 3 wks ago... I brought it up now since we are talking about size of the binary. If I remember correctly, the bionic patch is searching for working c headers and makes a new list before you compiles your source code... So that you are only compiling the usable source and remove the unused one.. The tool is find_your_cheaders.py. I have not used it and want to know if any dev on this forum using it with some experiences with this patch.. I will finish what I am doing and do more research on this topic and will bring you in with links and more information.. Thanks again for your opinions...

I am in a state of despair. If you are willing to help I will be greatful.
Basically i have followed Cyanogenmod's official build guide to set up the working folder up to preparing the device specific code, and then started following the TWRP build guide made by @Dees_Troy and this guide made for the Samsung Galaxy S Plus with custom # TWRP in the BoardConfig.mk and also added the twrp.fstab and the line 'PRODUCT_COPY_FILES' in i9300.mk and also 'export LD_LIBRARY_PATH .:/sbin' in the custom init.rc found in my device tree, but i cannot get the right size for my recovery. If you can help you can find me on the official #twrp on Freenode as 'Alexander_the_B0'.

I don't think there is FAQ with them listed. Maybe you could do the searching and make one?
However I know of this kernel you could try.

Are there any custom roms or stock stripped roms out>??? PLOX post links!!!!!!!!!!
I've been wondering the same thing since June. Seems like all the ROMs are geared towards the F/H/M. I've have tried installing ROMs for other variants with messi2050's kernel. The only one I got to boot was the Note 7 ROM by Allosh. But WiFi did not work.
Hmmm... Any other issues? What about that ROM allowed for you to boot and function I wonder?
If we can get a bounty going for WiFi fix on that ROM we could possibly be on to something....!!!!!!!!!!!!!!!!!!!!!!!

Just copy the wifi files in /system/etc from a stock firmware with a root file manager to the same folder and give it the correct permissions in the N7 rom. The real problem is getting the Camara to work.
I just want a rom with an AOSP based system UI.

My best advice for you is to deodex your factory ROM and decompile your system framework apk(s). All of the ports you see are derived the same way. This device will never see CM/RR/Lineage ported over.
Is there any custom ROM for j700t?

Why do you think this phone will never see CM/RR/Lineage? I think its possible, but we would need is a good dedicated dev that can figure out how to port or build them.

Actually it will be easy to port lineage for j700t, it only has different drivers and ram size than j700h

I agree. I would LOVE to try out a good lineage port. This phone really needs a good ROM, because Touchwiz really sucks.

I can go to git and setup the build environment, I've been following your work and aapav rather closely. I would just need your brain to help me change the ram and cache values and whatever else needs adjusted. Then once finished I could send you the files for upload.

nice, it will be the best to upload 7.1.1 and eventually 7.0 kernel source too.
I'd love to do it but i never uploaded on github.
So I just need to upload, no modifing or changing settings?

I could push them later but don't really see much point as most people will want to go forward rather than backwards 8.0 > 8.1 > 9.0 etc etc
Even with the Kernel source It will still require a lot of work to get a fully working device and will likely require some assistance from one of the more experienced MediaTek Dev's who are used to working with source code
I agree, but some people don't like Oreo and want to use Nougat. We can make another thread asking people for help.

we can overclock it from 1250mhz to 1300mhz, just a little difference. GPU can't be overclocked though.

Compiler Errors

I think the Oreo Kernel source is broken/missing bits which is kind of annoying when you spend hours fixing one thing then something else further down the build fails to compile and it quits. :crying:
It could be me just not knowing what I am doing :silly: as I am new to actually compiling kernels so still lots to learn for me but I would like to know if ANYONE has had a successful build or not especially someone who is experienced.?? :fingers-crossed:

How did you compile it? which toolchain and config files you used? I always get compile time errors, tried different toolchains and config files.
