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 .

1.Rooting is different from installing custom roms.
Rom is the android term for OS which is of many types.
Rooting is enabling ur device to access, edit & delete the rom components which include the built in applications to the codes that run the OS.
2. Stock roms are those which come along with ur device from the manufacturers which are usually called firmwares.
Custom roms are those which are developed by the android developers for the comfortability with many additional features! They are rated based on their performance, stability, userinterface, etc. The famous stable custom rom developing team is Cyanogenmod.
3. The are many methods for rooting and installing custom rom which are strictly based on ur phone model!
4. Rooting gives u further power! Custom roms gives u new experience in every aspect which means that the rules are bent for our comfortability!
HIT THANKS BUTTON IF I HELPED!

Hi All,
This thread might not be interesting to many "Geeks", who are aware of flashing custom ROM, Unlocking Bootloader, Get root access of your android device, Android Development and many more.
But your response might help few newbies who are still have no clue about these terms but wanted to do some techie stuffs wit their Android device.
Which is the best option you would prefer to ?? Newly rolled out fresh latest custom ROM on your device or Stick to same old kernel, baseband, ROM and wanted to play safely with rooted device.
P.S:- You can share the threads of discussion which are already shared so that this topic could bring an over all idea/benefits/Dos & Dont's of custom ROMs and Rooted devices .:good:
Hey guys,
Got on hands noname Chinese android phone with lollipop on board (even though it says 6.0.1 in settings) and MTK6580 quad processor, 3.10.72 kernel
can I somehow put cyanogen rom from another phone?
Yes, find another phone using that chip: https://en.wikipedia.org/wiki/List_of_devices_using_Mediatek_SoCs
Then go here: http://www.needrom.com and find THAT phone(s) and see if there is a custom rom for THAT phone also using the same kernal 3.10/3.12 etc
Download that rom and port it yourself using the boot.img from YOUR phone using this guide: https://forum.xda-developers.com/android/development/guide-how-to-port-lollipop-based-roms-t3223938
And get it at least booting on your phone, out of loads I've done on MTK phones, 95% boot up first time, 50% of those have no issues, the other 50% have issues with cameras/wifi/video/phone that can be fixed literally with trial and error of swapping files from your stock rom to the new rom, can take hours/days of trial and error or could take minutes.
Have fun
EDIT: try to use a custom rom from a brand you have at least kinda heard of, doogee, walton, infinix...etc to make it more likely to work well.

Thank you for your response!
After few hours of research I have found many ROMs that are applicable for my phone. The thing is, I want it to be and look as close to stock android as possible, and as close to most recent version as well.
But still I have few questions:
1)Am I right by saying that kernel 3.10.72 is suitable only for android 5.x?
2)Is it possible to put android 6.x or 7.x?
3)If it is do I need to ugrade kernel?
4)Is it possible to upgrade kernel?
I really hope it's not too much to ask from you.

Your phone is basically the same as mine, and sadly the kernal has to be the same for every custom ROM, there are no kernel sources so no custom kernels, which means we are both stuck with lollipop
The infinix hot 2 for example, is the same MTK chip and was released with lollipop and kernel 3.10 but then infinix released a stock marshmallow upgrade, with a stock 3.12 kernel so they could get a custom 6.0 rom which im 99% sure we will never get.
If you go here: http://www.needrom.com/author/robneymcplum/ this is me on there, where I have ported the best 5.1.1 roms with our kernel. You will need to port to your phone, which is literally just swapping about 10 files from your stock rom so make a backup of your stock rom or find stock firmware, and get the files from there and use the guide i already posted.
Hope this helps. And if you have never done it, its way, WAY easier than you think it might be
I want to buy a VIVO Nex s but i heard that Fun os has a lot of trouble in Europe. I also know that vivo normally doesn't release the kernal sources so my question was, do i need a rom specially made for this phone or can i use a general custom rom that works for almost all phones?
sorry for the noob question but i'm still new to all of this.
