[Q] Rom Development Issues

Hi.
I am trying to build custom rom for Galaxy Note(N7000)
I am trying to build a custom rom with base as stock rom(XXLT5)
I went through some tutorials on XDA, but they were only some basic stuff.
I had lot of questions in mind,and after searching for hours didn't get some help,so posted so maybe some one can help.
I flashed my own rom with some build.prop tweaks and changed wallpaper in framework-res.apk.
But it flashed with no problems.
1] I had lost root but I used Philz kernel(copied all stuff into respective folder)
2]I don't get about the META-INF Folder because I tried to put some s4 mods such as sec.settings.apk,s4 status bar,they also had META-INF but I didn't know what to do with it. I copied the apk of sec.settings into preload /syslink/system/app.
3]When the rom started default-wallpaper didn't changed and any mods didn't applied,so don't know what to do.
Can please any-one say what should I do,and where to put META_INF folder,because all apks aur mods has META_INF folder and will replace every time I put a mod in it.
Please Help Guys.....

Open original rom with WinRAR or 7zip, overwrite the boot.img file with the kernel you want to add, flash the rom.

Thanks <3
If you have a boot.img and system.img I'm pretty sure they would need to be extracted to make a flashable zip. Just throw them in a kitchen. If you don't have linux try Ricky kitchen or someone has modded dsixda kitchen and called it cygwin kitchen, meaning you don't have to install a virtual box. Ricky is windows based anyway

Do you have a flashable zip that works on your device? If you do, you can use the META-INF folder from that.

[Q] Roms structure

Hello!
Can someone explain to me what differences are between these roms? (see attachements):
I have MT6755 device and it's stock ROM has inside a boot.img, system.new.dat, system.patch, META-INF, etc..
And then I found a device which ROM has inside just boot.img, META-INF and system folder.
What's the difference?
If I want to port a custom rom, does my device need to have in a custom rom these files(system.new.dat, system.patch...) too, or can I use a "structure" of the ROM zip with just boot.img and system?
As far as i know You just need only System,boot.img and meta-inf also data if you wish to add an app as user

So if I want to port a ROM from device that has (system.new.dat, etc..), I need only to extract system.new.dat to get system folder and just use it?
