I know how to root and install legit custom OS as long as it works on my device. Is there a easier way to make a custom rom through Windows 11?

If you can't figure out these simple errors, how are you planning on building custom ROMs and debugging?
*Just wondering*
I was wondering the same. Building a custom ROM is not an easy task. You should really know the ins and outs of Android to even attempt it. Not knocking you, there are around 10 custom ROMs in just this forum. What would you add or build that isn't already available?
Not that you can't and cannot learn how but as stated above. Building a custom ROM can be quite the undertaking and you have to ask... What can you provide and offer that's not already available?
Firstly you need a decent PC for your build environment. One with plenty of RAM and storage. Ability to run or dual boot Linux and know commands. Can be built in windows environment though.
Secondly you need a device that you're willing to troubleshoot, bootloop, soft brick and or hard brick. Plus know how to recover from the above (hard brick excluded)
If you're willing, it's definitely fun, challenging and can be rewarding. I use to build my own personal ROMs a couple of years ago.
You can look at ROM development from beginning to end here and android kitchen here
Best of luck!!

I have successfully built a AOSP ROM I think.
I now have recovery.img, boot.img, userdata.img, system.img
Is there a way of making a n update.zip with these?
This should be moved to Q & A.
Yes, it's about development BUT, it's a question about development and therefore does not belong here.

Come on man do a Google search. There is information for making AOSP ROMs all over the place.
With that said, I strongly recommend heeding this advice:

Here's my advice for those looking to make their own Android ROMs.. Stop. Write an app or two first, learn how the system works from a developer standpoint. Learn some Java. Read the developer documentation. Learn how to use Git. Then learn how to build AOSP from source. Read the porting guides, and learn how the build system works (the links below have almost everything you could possibly want to know). Now try to put your new found skills to work on enhancing the platform by writing code or making theme overlays. And share! And put that **** on your resume. There is a *ton* of information out there but any kind of "step-by-step rom cooking guide" is going to be a complete fail- it's too broad of a subject.

The PDK site is absolutely vital if you are going to work on custom ROMs. Read every single page. Twice. Some of the info isn't up to date, but you'll get a really good idea about what goes into actually configuring Android to work on a real device.

Hi every one I dont know where to start i want to make my own rom from source,build it,modify it etc.But i dont know where to start.I know how to build rom from source(learned it from the tutorial on source.android) but i dont know what do those codes mean.i searched on google but cant find an easy tutorial.If i build rom from source how do i make it work on my phone.How do i FIX bugs on my roms,modify it Help please
Check out the chef central section under android. There are a lot of great people working on making development accessible.
For a pure AOSP ROM you are going to have a bit more work, but be rewarded in the end. There is also cyanogenmod and other custom distributions you can build from source and modify.
If you are familiar with C and Java programming you can dig into the actual development more by writing apps or changing source code. If you don't you may want to start on that road. Other wise you will be basically cutting and pasting from everyone else, which doesn't get you any credit.
Themes are also a good place to start. There are lots of good guides in the theme section and people are willing to help if you ask nicely and appropriately.
I have done a bit of this foot work and come to the conclusion, I need to learn programming then come back to source. It is overwhelming to take on an entire operating system in a foreign language, especially when that language has to be perfect to function!
Good luck in your endeavors. Feel free to hit me up for the little knowledge I have!

But! where to learn
First i want to learn the basics of Rom
are you familiar with Java, C and C++? These are going to be very useful in understanding the "codes" as that is what they are written in. You are also going to have to build AOSP specific for your device, which will require adding your device to the device tree and extracting the necessary drivers and files that are specific to your device. Cyanogenmod has many devices already added to their github and you would simply clone the folder for your device, then build AOSP source and issue make using the device specific folder.
THIS is a helpful tool, and yes it will compile pure AOSP as well.
THIS is also a very helpful tutorial, and you can modify instructions to work for Gingerbread.
If you just want to learn to build and modify the source start with Cyanogenmod build from their source first. You can also build the kernel if you choose but that is a bit more complicated. After you have both of those building without errors then start making changes that you want to see.
The CM Wiki has some good info http://wiki.cyanogenmod.com/wiki/Building_from_source
http://wiki.cyanogenmod.com/wiki/Building_Kernel_from_source
A bit of infos before starting this thread. I'm using a Samsung Galaxy S4 Canadian, I have a high end computer(maybe that helps for coding,stuff like that) and I have "medium" knowledge on rooting/flashing,etc. I am a great designer, well for myself, I think i'm good. So I can edit or create icons and themes for new rom!
I say medium, because the only thing I really know about this kind of stuff,is rooting,flashing,installing roms and pretty much that honestly.
I already downloading the Android SDK to test those custom roms i'd like to create. I thought of doing like a couple of guys on here, using the CM Source? and just adding stuff,etc.
--
What i'm looking to do, is creating a rom based of CM for the Galaxy S4 and just in general a little side project for myself and adding some infos in my head; Some may laugh because of the lack of knowledge, but hey! we all started somewhere
I'm asking the community of dev's or just users, do you have some threads or some stuff to download to "Start" this project ?
Some things I should read before, I won't test rom's on my phone as it's a daily phone, i'll use the emulator instead(AVD or SDK) and i'm already searching on how to run it.
If you have any useful youtube videos i'll gladly accept them
I found a tutorial on how to build a rom but for the Nexus 4, I guess it's the same process but different sources ?
I'll search for the sources of Cm for the Galaxy s4 but if anyone reads this thread and knows where to get it, please link me!
Thanks to the community, this may also be useful for other users. Thanks!
Okay, I will help
1st off, let me teach you some basics.
1.) You cannot test roms on the android sdk, the android sdk has nothing to do with roms, its for building apps and java programming. It will not help you with anything if an issue goes wrong in a rom, well only the adb (android debugging bridge) for taking locats.
2.) You cannot compile a rom on windows, only linux, preferably ubuntu. So you need to just download cm11 for your device and extract the rom zip.
I will tell you more later, but its like 1pm here Goodnight
How could I be able to build/port bugless Android 7 (Nougat) for MT65xx based devices (Specifically MT6582 device "Mine is Infinix Hot X507")? I am looking for building/porting a bugless Lineage OS/Resurrection Remix/AOSP/... latest release ROMs for my MT6582 device. I've no experience in building/porting Android ROMs. My question could be what are the topics/guides I need to learn from in order to have the skills of the person who is able to build/port a bugless Nougat version for my device?
It doesn't matter the topics/guides are for porting/building (also is it easy/hard), however the more convenient approach for me is the one by which I could have a bugless fully device-compatible ROM at the end.
I have good programming knowledge base and dealing with command line software. Also I will start learning Linux Kernel in few weeks after my exams.
I need your valuable help and suggestions. Thanks in advance.
Research/Outcomes till now:
■ I have read a little about porting. I understood that first I need a to-be-Port-ed ROM of another phone having the same CPU. I have found one here, but unfortunately it has some bugs. The publisher says that this version is unstable and needs someone to build it for MT6582. I'm looking for being able to have the skills to be that person .

First of all, chances are high you won't get a fully bugless one at the very first boot.there will be device specific files that causes minor bugs which you can only find and fix after the ROM boots successfully. This should be your primary objective,there are lot of guides for porting mediatek devices you can follow guides for marshmallow ROMs as its similar.
But i must it will be easier trying a marshmallow or lollipop roms first if youre new,anyway I wish you Good luck:good:
- Now to the ROM (trust me I know all about it)
It is based on 3.10.103 kernel so first you have to build one for your device. basic things like data aren't working in this beta release.
The publisher says he needs someone to build it for mt6582? Well,**** .
Building ROMs/kernels aren't easy but I'll tell you what is though ,stealing someone's days of work, put it in your blog without even giving some credits,this youtuber may not know about it so...I'm not gonna do anything about it
Will this build be fixed? It was ditched because of the above mentioned problem but I/other devs may release another stable build for our device(lenovo a5000) but it may or may not be available to the public
Edit :it's out now
Hi,
I‘m looking for a tablet as a development platform for gettting into custom android firmware development. What device (current or discontinued) is the most painless to compile a custom rom for with a current android regarding unlocking and driver support in 2021?
I‘m an electronics engineer and have worked on firmware for arm microcontrollers and did some kernel development for embedded linux (yocto) before.
I have the idea of creating an open source custom android for elderly people and small children that is pretty much locked down and has a simplified interface without cryptic messages. All settings, app installation and user support should be done from an app on another device. I think all the building blocks for this exists, I just want to put them together in one package. If you have suggestions for an existing base rom to build this on I‘d be happy to hear about it.
Cheers,
Rick
