Porting Ubuntu touch on Development board - General Questions and Answers

Hello All,
I have one development board and ported CM12 on it, Now I want to port Ubuntu touch.
I'm following https://developer.ubuntu.com/en/start/ubuntu-for-devices/porting-new-device/ guilde for porting Ubuntu touch but have some questions
1) I have build CM12 from source so do I need to download android source using "phablet-dev-bootstrap phablet" command ?
2) CM12 is ok for porting Ubuntu touch or do I need to switch back to CM10.1 ?
Please provide your feedback.

Download version has not fixes. Only ported from Explay fresh base to wiko base.
Now we are building CM11 from sources. Sound works fine now.
We need some time. The first bootable build was finished a few minutes ago.
Anyway @ariafan is working in CM11 for Explay base.

My work isn't succesful New kernel(version 3.10) doesn't boot up and i can't read dmesg because usb driver isn't loaded(kernel failed in early boot stage). And new lk.bin(compiled in 5.0 environment) don't working. It takes a lot of time to build bootable kernel. But if we have working 3.10 kernel we can easy build lollipop rom/cm12.

You can take a look at sprout 3.10 kernel source. Maybe this can help to port k80 proyect mt6580 to mt6582 .

I have full source for 6582(but it's confidential). Kernel from that source not booting. Sprout kernel doesn't help. I think there a problem in lk.bin.

I haven't source from this kernel. But it can be easy reconfigured for C2C, because Unite 2 and Canvas 2 Colours are phones from Tinno

Some minor info on porting a custom ROM.

Hey devs. I've worked with some ROMs and now I'm willing to port Blisspop ROM for my device. And all I have is the official kernel source, AOSP device source codes and some vendor codes using scripts. Now my questions are:
1. Are these data enough to start building the ROM?
2. I tried it using AOSP and CyanogenMod 5.1.1r3. But I always keep getting some files missing or compiler issues.
3. How do I apply patches from a URL?(I'm not fond of git)
4. Any link to a tutorial can be provided.
Additional info:
I'm working on Ubuntu 14.04 x64 LTS in VirtualBox.
Allocated 4 cores and 4gb RAM.
I'm porting it to an x86 arch device.
VHD size is 400gb.
And the kernel source is said to work with AOSP 4.4.2 though it functioned will with AOSP 5.1.1r3.
Also I followed several guides but most of them are for arm devices. And did not workout for me.
Kindly help me out guys.

You need to make it by yourself from source
Also
As far as i know
Ubuntu touch is based on kitkat
Which we don't have any device tree based on kitkat
