I´m going to start building my own ROM, I (think) have found the source needed for my device LGD373 (opensource.lge.com) the code available is for KitKat, but i want to compile it for Lollipop.
To be more precise, i want to compile PacRom Lollipop for my device, i will be able with the released code? if not, can i build the KitKat version of PacRom?
Thanks in advance

Hi. I have this question. If I have a device config source, how can I modify it to make it compatible to newer android version (also or cm)?? My goal is to port a build to KitKat.
Thanks in advance
I have a LG P350 which development has stopped but i want to keep it updated, i have my computer ready for building, also i have kernel sources, Cyanogenmod 11 and 10.1 sources too, (I don't know exactly if 10.1 sources could help) and i know that i need to apply patches to work on Armv6 but i don't know how to apply them to the source code, also i don't know if i would just need the pure source code to build or i need to do more modifications to it and finally, i don't know if the rom would work with 2.36 kernel which it's the most stable one for this device, i'm very new in this but i know that i can keep update my little phone, thank you all in advance for help.

Hello, looking at your situation here is what I can conclude. First off you will need to change things for building on ARMv6 architecture, check this out for example. But your biggest problem will be that Android 4.0+ uses Linux kernel version 3.0+, and with the 2.36 kernel you have a lot of things will be broken and need fixing. That being said if your up for the challenge for it cause that's what were all about .

Well, i got this http://forum.xda-developers.com/showthread.php?t=2144790 that is the most similar phone talking about hardware, it has 3.0 kernel working well so i thought i could port it, i found this http://stackoverflow.com/questions/15961306/porting-kernel-from-another-device so i think i would have less problems due hardware similarities (Look here http://www.gsmarena.com/compare.php3?idPhone1=3516&idPhone2=3735 ) so, if i have cm11 pure sources, i add this kernel sources and some patches i would have it booting? Sorry for this very dumb question but, i didn't get at all about the armv6 part, how to apply patches, which i would need and all that, i really want to learn about this so thank you for this answer and the next ones :good:

The best way to start is use the ARMv6 branch of Cyanogenmod 11, replace the CM 10.1 in the previous linked build guide with cm-11.0 ("repo init -u git://github.com/androidarmv6/android.git -b cm-11.0"), and then to direct the build to use your kernel take a look at this guide on integrated kernel building with Cyanogenmod.
Hi,
As some of you might be aware of, Sony released the sources to enable building of AOSP straight from their sources for the Z2 (and other devices also).
I was just wondering if any of you has been able to build from those sources ?
I can init the repo.
I can sync the repo.
I can build the envsetup.
But then when it comes to compile the whole bunch, I always end up with an error message stating the I use a version of Make that is too young (4.1) and that I should use 3.8 instead...
Any clue on how to solve this ?
I guess it's trivial, but I have no idea how to proceed
Regards.
I've been trying to figure out how to build Cyanogenmod from source for a few devices. I've looked at many tutorials and such, but I haven't been able to find one that explains how to build Cyanogen for a device that had an old version of Cyanogen but hasn't been updated since. For example, the official builds for a certain device only go up to 12.1, but I want to build it for 13.0. Does anyone have any advice?

I would recommend starting by using the device tree for your device that supports 12.1 and try using that tree to compile 13. To do this download the 13 code and put the 12.1 device tree in the proper folders (device, vendor, kernel) and try compiling a build and start seeing what errors you get. Let me know if you still have questions I'll do my best to help you out!
Hello guys.
This question is specially for devs or advanced users with development skills.
My question is related to the kernel source of one of my devices, Huawei Mediapad T1 10 (codename: hwt1a21l). I got the kernel source from the oficial Huawei website and uploaded it to a github repo. My device, which has a msm8916 chiset, doesn't have any development (roms, recoveries, device tree, etc) and his rom, EMUI 3.0, is based on Kit Kat 4.4.2.
I have been trying to bring development for this tablet many months ago because the stock rom is too deprecated for the hardware that has, with the msm8916 there is a huge potential to bring it a lot of development.
Well, i'm going to summarize my problems when trying to bring development for the device:
To get started development, for example a LineageOS build i needed a solid base to start with: device tree, propietary blobs and kernel source, so i got all of them. I ported the device tree from another one very similar to mine (with the same chipset), extracted the propietary blobs with the build tools from the source and got the kernel source from the Huawei website. So everything seemed to be good, but when i start the build process with my Linux machine (repo sync > source build/envsetup.sh > breakfast hwt1a21l > brunch hwt1a21l) i always receive thousands of build error by the kernel source, and i have been fixing (or at least avoid) a lot of them but it never ends, so i don't know if it's worth to keep trying to "fix" them or if i'm wasting my time.
So, what i have been trying to do: i have been trying to build a LineageOS 14.1 and TWRP recovery with my device tree This: Mustang-ssc/android_device_huawei_msm8916-common ported from this one from @dianlujitao : dianlujitao/android_device_huawei_msm8916-common and the specific kernel source for my device downloaded from the Huawei website Mustang-ssc/android_kernel_huawei_hwt1a21l. Here ends the summary.
So after a lot of hours, days and nights over the last months trying to make progress with this and not getting any help from the few devs i asked after seeing my lack of progress i decided to publicly ask for help.
The questions:
1. I have the official kernel source (Mustang-ssc/android_kernel_huawei_hwt1a21l) which i didn't have success to compile it, and then i saw the kernel source from a device almost identical to mine (same chipset, brand, ram, ...) (dianlujitao/android_kernel_huawei_msm8916). Can i use that kernel source as a base for my device after porting the specific configurations of my official kernel source (defconfig, drivers, libraries)? That one is much more updated and probably optimized than mine, but i don't know if it's possible to adapt a kernel source from other device using your kernel source.
2. This may be a dumb question: my device has Kit Kat 4.4.2. Is there any link between the kernel source and the android version the device has? I mean, i don't know if i should do something to adapt my kernel source for newer android versions (Marshmallow, Nougat) of if it's ok to just build with it without any change.
If you read it all, congratulations, you're awesome
