Hi, I am currently building custom rom for my Lenovo a7000-a (aio_row) and I have a few questions regarding the device section of the AOSP build.
1. I have seen that to build the custom ROM for a device, I would need the following .mk files from topic "Android device configuration AOSP" in Stackoverflow.
However, from the device configuration/device-tree(?) from user rohantaneja in Github, I see that I would also need files that look like drivers for the devices based on the files on that github. May I ask how would I obtain these files?
2. Would flashing an arm64 generic build of custom AOSP into any Android device work or not? If so, why?
Seems like the amount of knowledge that I faced off with confused me a lot.
Any help is appreciated.
Thanks in advanced.

Hello there,
I am currently having a One Plus One. I have multi-rom utlity which allows me to have multiple android OS installed.
Currently the cyanogenmod based custom Marshmallow Rom I use (http://forum.xda-developers.com/one...m-kernel-unofficial-cyanogenmod-13-0-t3242700) has switched over to using stable CM branch as their rom base. So this requires using Super SU for root access. Unfortunately Super Su is not compatible with Multirom implementation for OPO.
One suggestion provided was to try building the custom rom from source with user-debug flag. Meanwhile I came across two build.prop values (ro.build.type=userdebug ; persist.sys.root_access=1) which I hoped would enable inbuilt superuser without rebuilding the rom from source but they did not work.
So for now, there seems to be no other way around building from source ( I wanted to avoid this as much as possible because I have a very slow Internet access downloading 30 GB or so for the ROM alone will take a month for me).
So here are my 2 questions:
1> The rom developer in the thread mentioned in 2nd para, talks about 2 source (Kernel and the rest). When I looked at the manifest, they talk about replacing something. So does this mean I need to download the cyanogenmod sources as well or does repo sync take care of that automatically ?
2> I assume the kernel and rom need to be built separately. Can the "userdebug" mode be enabled only by rebuilding the kernel and then placing it with rest of the rom build zip provided by the developer to avoid rebuilding the whole rom ? or better yet flash the my userdebug kernel again after the normal rom installation ?
Thanks In Advance

Hi! I own the Nexus5X and I am interesting in creating a custom ROM for the device. I have synced the AOSP source tree, gotten everything set up and flashed a build on to my device.
How can I start creating a ROM for the device? What are some general guidelines? How do I start tweaking apps, adding features, etc.
Also, if someone could take a look at these errors I am getting with my AOSP build that would be awesome: https://forum.xda-developers.com/nexus-5x/help/issues-aosp-built-source-bullhead-t3555439
Thanks

Hello,
If you have interest in develop a custom rom, i suggest you start at XDA University to learn a bit of everything about Android.
You have some great guides on Android Software Development (look at stick posts)
I have my own guide which is not finished but I will teach everything you need to know about build a custom ROM from source, how to use github, git, mergetool etc... You can follow my progress HERE

OK thanks, I will take a look at that. If possible, could you take a look at the errors I am getting with my AOSP build? I posed the link in the original post. Also, do you have to run extract-files.sh or can you simply download the vendor binaries from Google and run the extracting script? (AOSP)

If you fork/download vendor binaries you don't need to run extracting script
Hi, I'm completely new in Android ROM development and want to get into it. I have a Moto G Turbo and a old Moto E 1st gen.
So I had some question regarding Android ROM development. I may sound completely noob which I am, but still if you help me by answering my question or at least referring to some links then I'll be helpful. And please only answer if you are confident about what you are saying.
1> I understand that Android is open source, so basically we can download and build it. What does it take to make that boot on a particular device?
2> Android is based on linux kernel. So we need a kernel source too. I found this, https://github.com/MotorolaMobilityLLC/kernel-msm, is this the kernel source for moto devices? I am confused because I can find only one repository although it must different repositories for different devices.
3> If we have a kernel source for the device, can we build any ROM like AOSP or AOSP-CAF and boot it in our device? If not why?
3> I have a good knowledge of C although I am still learning. How do I start developing or porting ROM? I am specially interested in PURE AOSP.
I don’t know but you might find a lot of tutorials in non-device-specific threads. And I think there’s a guide on how to build lineage 13 for osprey

I have an One s with S3 processer(villeC2).
Its specs are similar to sensation(with same cpu and screen resolution),but sensation has Android 7.1 ROM and one s only 4.4......
I would like to port a ROM for it from sensation.
Does anyone know how to do that?
Or if it is possible ?
(sorry for my bad english)
(my first post)
Some info !
Hi,
Actually I'm new in building roms and kernels, too. But i can share some info with you.
For starting this tutorial may be helpful: [Guide] Compile 4.2 & 4.3 & 4.4 Roms for villec2
As you can see, you will need "device", "vendor" and "kernel" source to build a rom.
Usually you can find source code of roms and kernels in xda threads and can start from those.
For example for Android 7.1 you can use RROS vendor and VilleC2 device and kernel sources. (Note: i don't know are these examples compatible or not?!)
And for kernel, maybe you has to upstream the kernel source to be compatible with new version of android that you want to build.
Good luck.
-----------------------------------
Edit:
After Compiling for myself, i figured out Vendor files for choosed rom (Lineage, RR, ..) will be included by their manifest files automatically. so for "Vendor" part in "local_manifest.xml" (or newer "local_manifests/roomservice.xml") we need to assign "proprietary_vendor" files related to our devices. "proprietary_vendor" files can be extracted manully if there isn't any online source.
one more useful guide: [GUIDE]Building any ROM from source for HTC One S aka ville!
So I have decided I want to make my own rom. Where are the binaries to use for the ROM? Some randomer I saw had been trying to make a lineage os that works with this phone and he put the firmware in a GitHub file I think. I would like to know where and what binaries are needed.
@sd_shadow it would be great if you could help me.
