Build kernel without source - Android Q&A, Help & Troubleshooting

Hi guys, this is my first question here. I wanted to build the kernel for my Micromax device (Spark 4g Prime), but micromax doesn't release the kernel source for its devices (gpl violation, yes, but it's a small company). I really searched everywhere, but could not find anything to help me. I did see a post by @dev_harsh1998 here where he mentioned that lenovo had given broken kernel source for his device, so he "reverse engineered" the kernel source from the boot.img. I didn't find anything on how to do that, can someone please help me out (or point me in the right direction)? Thanks

Here,

Hi, I don't know if still helpful but building kernel in android is the same as linux and the same for evry device.
You may follow this rule to build your own kernel and patch it with the patch you find online or in other kernel thread.

[Dev][Discussion Thread ]Cyanogenmod(Jelly Bean) Build

Hi guys,
I made this thread for all the developers to discuss about their new projects, errors while building, source building, help and support, CM bring-ups, patches and fixes, since we don't have a "Developers discussion" forum for our devices and developers too. :laugh:
It's a nice place for newbies like me to learn a lot from the awesome devs here. :highfive:
This place is just for developers and people trying to build ROMs from source or kernels.
NOTE- THIS IS NOT A PLACE FOR BUG REPORTING OR REQUESTS
IF YOU ARE INTERESTED IN THE PROJECT PLEASE PM ME YOU NAME.
Try to keep this thread clean :angel:

How to download cm10.2 source.
http://forum.xda-developers.com/showthread.php?p=52339783#post52339783
This local_manifest made by nolinuxnoparty is kinda a messy(From my point of view).
https://github.com/nolinuxnoparty/android_device_samsung_delos3geur/blob/cm-10.2/README.md
It messed up my source(whole).So just to prevent if anyone downloading any source code ,download the source first than make a backup of it than mess with it
RESERVED
i found this device tree (cm 10.1) https://github.com/OUDhs/android_device_samsung_delos3geur
can this be used to build cm 10.1 for our device??
to me it seems like this device tree is incomplete...
also if someone has any knowledge about device tree pls teach me what it basically is and how it works... if you know of any threads about device tree pls send me the links...
Tks..
Nolinuxnoparty has revived the project on github of cm11 branch

Don't know about that source code looks incomplete to me...
A device tree is a tree data structure with nodes that describe the physical devices in a system.Device tree is basically a colletion of data about our phone.It is like a king and source code is like a worker .It tells how to make changes in the source code to make for custom rom etc.... for our phone:laugh:
Here read this:
http://elinux.org/Device_Tree
If you want to make than try this:

please correct me If i am wrong

Friends ... pardon my intrusion, but I've been reading the topics about our grand quattro for this CM ROM, I do not know desemvolver noob and do not have a legitimate developer today ...
But the tree of the handset MOTO G would not help us because it is a device compared to ours and already have CM ROM would help? If yes glad, if not sad I apologize ...

@PiKay ,
you would have to know that CM devs cannot just port the rom to any device since they have no real device to test.
so, i do believe CM devs would be one of us who already own G7102 and wish to encourage and spend their time to maintain the code.
( unless someone gather the donation to buy G7102 for dev who would like to dev G7102 to us also? )

Yes please keep spamming their forums that will be sure to gain support.
in the event anyone actually wants real support, i would suggest reading the sticky in that very same subforum everyone posts "HALP I NEEDZ CIANOGENZMOD!111!" http://forum.cyanogenmod.org/topic/72611-can-i-get-cyanogenmod-on-my-device/
@sudloa hit the nail on the head.

[REQ] Device Tree for A7 SM-A700F

Hello
Thanks to Xda member ShinySide we have a root solution for our device and thanks to ashyx and Xperianoobie we have a recovery.
In order to get some custom roms, we need to build the device tree but we dont know how, so if any devs would be willing to help us out with this we would be very grateful!
Or if someone wants to build a Cm rom for this device that would be awesome!
Device is the A7 SM-A700F exynos version
Latest official firmware: 5.0.2
Thanking you in advance
Jay
Bump?
I tried converting Galaxy Alpha Device tree to a7alte. But it's really hard. Didn't work.
Building ROMS won't be a problem, but I need a device tree. Can't find anything for the a7alte on Github or something. Really irritating.
Thank you for all your efforts!
Let's hope a dev will see this thread and help out.
Error

[Q] Build device tree, vendor and kernel for building ROMs

Hi
I was wondering if someone of You could give me some advices about building the device, vendor and kernel tree. I tried with info found in google, but it seems not to work good. Well it doesn't work at all. I searched xda, but no-one gave precise answer. It would be really nice if there had been some answers
I really count on You, Devs
Thanks in advance
