[NOOB] What shall I learn? and how to start porting newer android?

Right, I wanna start modding my phone now that i have some spare time. Just two things I need to know:
1. What code languages do I need to know?
2. How do I start porting a newer version of android to my phone when I know the languages? (any tutorials or guides or anything?, my phone doesn't have an unlocked bootloader so I know this will be a problem, but it still can be done)
Please just take two seconds of your time to help me
Thanks in advance

C'mon guys, all i wanna do is learn. is there anyone that can help me??

As far as I know, you would want to build Android from source. In your case, try looking at the CyanogenMod source.
There is also a wiki entry on the CyanogenMod website, showing you how to build CyanogenMod from source.
Knowlegde of C/C++ and Java will prove useful, as well as any knowlegde on Linux.

[GUIDE] Custom ROM development for the rest of us [In Progress]

*** THIS IS NOT JUST ANOTHER EFFORT TO CREATE YET ANOTHER CUSTOM ROM***
Though Android is opensource, a lot of things are unknown regarding ROM development/modification. There are many custom ROMs available for Galaxy 3 (and also other phones) and lot of people are flashing them and making their phone more responsive, productive and faster; but very few people actually knew how to go about developing the ROM.
What I intend here is to find out and document correct way to build ROM for our favorite Galaxy 3, which is very popular in India.
The goal will be to develop the ROM from Android source + Drivers from stock ROM while documenting the process so that large number of people can contribute to the development.
I will shortly update the posts with what I have done.

Making one aint difficult keeping it bug free might get sometimes

Thanks rudolf895
I have experience in Android SDK and NDK development, but I am a noob when it comes to ROM development. Thats why this effort.
I have fetched android source using repo as well as I have also downloaded source for I5801 from Samsung open source website. After this I will look into extracting drivers from stock ROM and successfully compiling it for Galaxy 3.

hehe, cant wait to see what you come up with, sounds promissing btw... i am also willing to help whereever i can, whereas this wont be too much in this case i guess.
good luck and thanx...

TY ..!
Thanx alot
This would be really helpful to alot of members here

interesting ! waiting ....

I applaud your thread, I myself was thinking about such a concept.
I wanna help, but I cant do that much (basic knowledge of C and basic/little knowledge of linux and adb).
I think first there should be a list of basic stuff. Like compiling the sources, extracting factoryrfs and co from your phone etc... Sometimes if you wanna start doing something and you dont know the basics you get scared off because of their apparent tremendous lack of knowledge.
I'd probably start dabbling if somebody told me how to compile the sources.

can you also specify your work environment, toolchain and such stuff, so anyone can start from zero? there is a kernel building vm image with all tools by sztupy somewhere on the forum that is eventually of interest, and there is also an extended version containing eclipse and some more tools for full android development:
http://forum.xda-developers.com/showthread.php?t=882010
hope this helps somebody...

Did you try using it? I think the scripts are specific and cant be used by us (without altercation)

no, i have absolutely no idea of kernel compilation and all that advanced stuff, but i guess it can be adapted for our use

Yup...me too in waitin line...Now i can say i dint made a mistake by buying it...

[Q] How to create my own rom.

Hi,
I'm following the Nexus S Android Development for 6 month now and Rom and Kernel flashing is a a real addiction for me (I flash everyday).
And, since the beginning i want to create my own Rom.
At first, I want to build one from another one (Cyanogen or another).
So, If someone can give me tutos, tools, tips and advices, I'll be very grateful.
Thanks to everybody, waiting for your help.

Hey you know i find myself sharing this exact interest as you. Let's collaborate and learn this Create A ROM Project

Notice to see the motivation to create a new ROM.
How good are your Linux skills? If you want to do it all properly I suggest you try and build your own AOSP ROM first (from the Adroid Open Source Project).
This is the place where Google publishes the Android source code files. Actually the site is fantatic and guides you through the entire process, but it does require you to understand the basics of the maketools in Linux.
Once you've been able to compile the source, you'll actually have a perfect stock ROM version of Android. Then, you can start doing advanced things to it. Add a different Kernel, add apps, install tweak scripts etc etc etc, the options are endless.

Good luck and have fun, because it is

[Q] Building AOSP (not CM) for the OPO, is it possible?

Hi, I've just received my OPO on the 27th. I was really interested in Android development when I had my Nexus 5 and started building my own AOSP ROM, I've been looking into doing the same for the OPO but am unable to find an actual way of building AOSP with Google's code. I know OPO released their AOSP kernel source here: https://github.com/OnePlusTech/android_kernel_oneplus_one and CyanogenMod has thiers here: https://github.com/CyanogenMod/android_kernel_oneplus_msm8974 but I'm unable to work out a way of including these into my AOSP build and I would prefer to not build CM.
Note: I'd like to build AOSP myself, I'm fully aware that there is a current official OPO build available.
Thanks in advance,
Lewis

It's advisable that you create your own tree from the CAF MSM8974 using CM GPS and other drivers and build CAF AOSP. Otherwise, it's close to impossible/very difficult. Pure AOSP is again near impossible/very difficult for non nexus devices.

Thank you very much for the reply, so building AOSP is pretty much impossible then?
I was having a look around on the internet last night and came across this: http://developer.sonymobile.com/kno...uild-aosp-kitkat-for-unlocked-xperia-devices/
Would there be a way of adapting this guide to allow for an easier build process of AOSP for our device? The other confusion that I face is if it's impossible to build AOSP for the OPO then how are ROMs such as this available?

VanirAOSP uses CM trees as of now. Again, CAF AOSP is basically AOSP for non nexus Qualcomm devices., and any experienced dev can whip up a tree and get it working. Also, reaally good devs can/may be able to port AOSP if they wanted. It's a matter of whether they want to do it or not.
That link is for Sony devices only because Sony already provides CAF trees as an OEM so devs can build.

Ah yes, I see what you're saying now. Thanks for clearing this up for me! I just noticed when I looked at the VanirAOSP ROM thread that it states CM for it's credits, haha. I apologize for my ignorance.

Hello
I would like to create my first rom for oneplus one but without modification from OMNI or CM, basically vanilla rom. but I have some doubts.
Can I create a rom based on AOSP with device tree from OMNI/CM right?
Thanks!

WIP* ( port) Linage OS LG Stylo 2 plus

Development is dead. Please delete..

Rmontoya83 said:
Good news I have a working Linage OS 13 build for the lg stylo 2 Plus GSM. Thought it was bug free still has some issues though . My PC took a dump I have the sources saved on my hard drive I will have a new PC on Feb 6 and will release the Rom For Free probably with in a few days from then. As I'm almost done porting a working lineage OS 14 for the device.
I will update the device tree on Github So I can get help from other devs to trouble shoot these issues better and collaborate works. I will also include a working recovery with the Rom for free . I am doing this in my free time so please be patient .
I will keep you posted ?
Any people interested in helping let me know.

You can downgrade your firmware .

Nice work let me know when the source is up at github , i may be able to help

I'm so anxious I can't wait to get my new PC! I will be compiling a lot faster. You guys are going to like this lineage OS port. Hang in there

Any screenshots?
I'm interested in this also

Not at the moment I had the backlight on my display burn out . had to flash the stock rom back for warranty purposes and for some reason every time I try and back up via twrp the data gets corrupted.
So the only place I have a working Rom is stored on a hard drive and I get my PC back on the 6th this month so it will be up soon.

Got the new laptop up and running building starts tommorrow.

All souces are downloaded . I will start building the device tree tonight hopefully by end of week myself and @messi2050 will have a working lineage OS build for the ph2n. I stood up all night working on the list of proprietary files need for the build.
Now comes the hard work of adding all the required blobs to get it all functional please be patient. As we are doing this in out free time. Once the device tree is all setup it will be a lot easier to port other roms to this device such as omni aokp DU and so much more. I chose a 13 build as I'm new to this and its a lot easier to port a Rom that has many components that are stable with the version.
If you appreciate our work buy us a cup of coffee. Or hit the thanks button for the Devs working on this build .
Thanks to all the xda community.

We should work on a changelog concerning drivers for cheaper models like my tmousa k550.

Montoya, how are you getting the blobs? I have root when want it, I just don't right now. I have teamoctos synced, I have all the source code for our device. I'm not much of a programmer, but let me know I can help. I have Ubuntu with all the packages for compiling.

has one repository done for device /device
i have the other kernel/
i am working on the blobs using @JackpotClavin utility tool to pull all the blobs needed for the build. once we have a stable tree we can work on building other roms.

Good news we have the the last branch to the tree built so builds will start this week sometime. We have a lot of work ahead still so be patient.
Tree source and blobs are on github.

Both you and Messi are doing amazing things. When this is done, both of you are getting a cup of java (I couldn't resist Java instead of Joe or Coffee). I downloaded the jackpotcalvindonkey thing yesterday, did the make on it, but didn't get it out.
Btw, your github shows no public repos.

Well that was quick
