I want to do rom development for my friends unbranded Android phone. I wanna make a KitKat rom for his phone. Im a developer so I have a technical mind and have read some Android kitchen tutorials here on XDA and I was wondering, I know how I would make a custom rom for a unbranded phone by just dumping the rom off the phone in question BUT how would I go about updating this rom to a later version?

To be honest being able to use a kitchen doesnt make you a developer. You would been to back port all the drivers and libs to work on a device that it wasnt meant for. You would also need to hack the kernel to work. The device will need to have kernel source posted as the current kernel will not work on an updated OS.

yeah, I didnt mean I use kitchen so I know what im doing, I ment like I have developers experience (in Obj C and such). Might give it a whirl but I think I might be too novice to go to kernel coding.
Actually I have many question
I think when a newbie like me start to work on rom development then there are several questions arises in mind basically like what I am going to ask here, my purpose is to get all this doubts cleared before starting so that I can start to focus on things. I don't know if my questions will help other newbies like me but it will literally help me a lot .
I am trying to develop a custom rom for ascend g700 as i have seen it among the most hated device among developers , no one want to do anything for this phone and it can accomodate a lot of upgradation. I have seen g700 users begging inside CM forum to build a latest ROM for this device, I have also seen g700 owners begging on huawei website to upgrade their devices but huawei doesn't even feel like to give a word to it. and I feel really bad about this .
So i just want to build a good looking, working, clean, latest by look and feature rom for Ascend g700 for all users, there are various reasons why I want to do that:
1) One of the biggest reason why I am here is I want to see g700 users smiling with joy that finally somebody has updated their device, I want all g700 owners to feel worth buying the device.
2) No working custom rom is available for this device yet.
3) No Cyanogenmod rom available.
4) This device configuration seems potentially great which literally needs update (atleast up to kitkat).
5) And personally I don't like UI emotion of this phone besides that google play store has some bug which makes icons background looks black which is a sore to eyes, Huawei did nothing for this device yet except just earned the bucks from it. I hate the companies who are ignorant about their customers.
I don't want to bore anyone reading my thread but i have lots of questions to resolve before i start to develop something for this device and I hope i will succeed.
Okay so let's get started with my questions, all veterans are requested to kindly share their vast knowledge and help me understanding the facts. thanks in advance .
Objective: what i am trying to do is, trying to find out the latest possible (Lollipop) rom which I can use as base rom to flash this device (Ascend G700) or just build a custom one fully working.
1 First: Are there any neutral latest android rom versions are available from google official websites to start using on any device or to start develop it for any particular device?
If "yes" then from where i can get it?
If "No" then from where the companies get their android roms on first hand as a clean plain base android rom to make it their own rom?
2 second: Can i just install any rom of any phone and it will start to work?
If "No" then what maybe the problems that I would first encounter?, what can I do to fix that any such known problems?
3 Third: I have heard about porting rom by changing things inside rom like replacing kernel of base rom with my stock rom, Kernel of my stock rom (4.2.1) can work with lollipop rom (5.0.0)? if yes then which lollipop rom would be best to use for (G700) and from where I can get one?
4 Fourth: Can I use my old kernel, camera and radio from stock rom in newer lollipop rom will it work? is it possible to do that?
5 Fifth: Can I use any kernel on any phone? or there are any specific particular to device types? or is it necessary to use the old kernel?
6 Sixth: If I flash my phone with custom new rom the radio will also be flashed with it automatically? even if I doesn't want to? How would I know that the rom i am going to use contains the flash files for radio also? and can i remove that? and use rest of the rom?
7 Seventh: If i flash my phone with new custom rom what are chances that it's camera will not work? or radio maybe affected?
8 Eighth: What can i do to port my camera from stock rom to new custom rom which I want to flash. the camera of old rom (4.2.1) can work with lollipop (5.0.0)?
9 Nineth: The device is a dual sim, any special thing to keep in mind before flashing a rom? a rom should necessarily be valid for dual sim? are there any specific types?
Please all the veterans from XDA are requested to provide inside to all these questions of mine, so that I can start working on my custom rom, I seriously want to upgrade this phone please help
Any help from anyone who knows anything related to any question of mine are welcome to share their knowledge.
Thanks in advance .
I have Infocus M2 3G running Android 4.4.2 . I want to make a Nougat rom (preferably AOSP). I read many posts on various forums on making rom, but I'm still confused : Please suggest the most reliable and easy method.
there is no "easy method" you have to build it from source or port it over to your phone. Nougat needs at least 1.5gb to run it smoothly. Not I am not
helping you either.

I need rom too for this phone
As the title suggests, how do I make a rom which is a more recent version than the stock? I have a Huawei Y625 which doesn't seem to have any custom rom. So I'm stuck with kitkat and really want to upgrade to something like lollipop or above. I would really appreciate it if someone could help me.

Start there, Best of luck.
Hello Folks,
I have a question in my mind, Over the year i have used many devices and on which i have used many Custom ROM.
Why do we have the ROM update option Missing on most of them, if any ROM does have it then its broken ?
I mean, our devs here are way too qualified to do that, if they can develop and port these roms i mean they can definitely do the auto OTA thing right ?
Can someone please explain me where I am wrong ? Its not done yet means there must be a huge challenge which i am not aware of ?
Thanks.
