Need some help porting GPE ROM to our device. - Sony Xperia Z Ultra

Hello community!
I can't wait while someone porting a GPE Rom, so I want to get involved.
As far as I understood in order to build a rom I need:
The System Dump of GPE ROM
Build a new kernel from GPE kernel sources.
Write an Installation Script
Correct me if I am wrong.
Now, Dear Community I need your help.
Tell me what knowledge are required to get this work done.
There too many different tutorials for cooking roms, so I kinda messed up.
If it's not hard for you, can you give the links for some good information that I will need.:cyclops:

Get to my thread here and do it to the end. I feel like my XZU accidentally died for some days :crying:

[Q] Question about step 1 of GSM flashing if already rooted/modified

1-SBF to stock base. Root your phone, unlock bootloader, install custom recovery and perform a nandroid backup of your stock rom!

So my question is all based on this, and after a lot of reading I found both answers but both were old so not sure which one to trust.
I am currently rooted, unlocked, running joker's CWM & Joker's CM10, and have a nandroid backup from back when I was running stock.
Is step one really to roll back to stock base, re-root my phone, re-unlock my bootloader, and make a new nandroid backup? Or are these instructions assuming we are not already rooted/unlocked?
Can I skip step one and just flash the new radio and then Joker's GSM CM10?
(Long time lurker, first time poster, 9 different phones hacked to bits and this is my first question ever, if this has been asked before no combination of GSM/Stock/SBF found it.)
Where can find definition and terminology
Can someone please give the link to the post/forum where we noobs can find definition and terminology on ROMS, kernl etc. ?

expertglossary.com/android/definitions/R (Banned from posting outside links.. Jebus it is hard being new, and all I could think lurking was I wish they had a method of making people talk *less*)
This might help a bit, ask if you want anything clarified. Their ROMS definition is a little not perfect, A Rom as it is normally used here is a zip file containing all the bits that makes an android install, A custom rom is a bundle of the kernel and android version, tweaks, themes, fixes, modifications, basically everything you use on a system as tailored by the ROM builders.

I was thinking more about " a guide to noobs" here in xdadevelopers forum ?
Where can I find it?
Definitely here is the best we have forum.xda-developers.com/showthread.php?t=1393519 then you follow all the myriad links based on what you are trying to do.
Not being sure what your goal is it is hard to be more specific.
Anyone have an answer for my earlier question though? My sim card arrives tomorrow.

Hello… 1st off if your new and haven't done so give this a good read http://forum.xda-developers.com/note-3-sprint/general/samsung-note-3-rom-flashin-basics-t2896440 so you have a better understanding of what you are about to get yourself in to. Give jimzweb1 and thank you when you get over there for putting this together. Any of the custom roms here will very from rom to rom. Its near impossible for anyone to say what rom is rite for you. Best thing I can say is as with any rom . Pick a rom that is made for your firmware. These day you can get away with using NK4 with NH7 intended roms. For exsample : im running the latest fre3 rom made for NH7 and I updated my firmware to NK4 and is running ok. (But please read up on it first) So pick a rom you think you might want to run and research, research, research.(The more knowledge you have the smoother your install and over all experience will be.) Look at the features listed for that rom and user feedback with in that thread. Also in the Q&A most roms are listed there with user feedback. Most if not all of your questions have already been answered you just got to look a little. Also the search bar with in any thread is a very useful source of information when choosing a rom and finding answers to your questions . BE SURE TO MAKE A BACKUP OF YOUR CURRENT ROM/SETUP just incase. And follow all rom install instructions to the T for each rom you try. This makes it less painful for developers and others to help you if anything goes wrong. Rom installation may very from rom to rom. Good luck and happy flashing!

Rom porting question.

I've been searching all the rom porting guides and threads I can find, but none seem to apply to my scenario, or I'm not sure they do.
I have a base AOSP rom for my device (CM12) and I want to port Paranoid Android or Pac rom. All the guides I've found don't say if they will work for lollipop. If anyone can point to me a guide that covers my situation, I'm certain I can make it work.
Thanks in advance for any help.

developing custom rom for G700, all xda veterans please help me!!

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 .

Seeking help porting a rom.

Hello,
For the past weeks I've been trying to port various ROMs (Same SoC and kernel, 3.18.19) to my MTK6580 phone. I've always went the copy-paste one by one route though they won't boot. I feel like I'm doing something wrong here, I've tried following ALL the guides I found. Could any kind person port me a Lineage OS, XOS or something else as long as I provide the stock rom? I just need it booting, I'll tweak it from there if it's needed. Thanks.
