[GUIDE]How to extract Stock firmwares from Samsung? - Galaxy Ace S5830 General

And,comes another guide from me.... I was actually extracting a stock firmware and this came into my mind
Ok,I made this guide since the process of extracting firmware is a bit confusing sometimes.So,lets start with it​
What you would need:
1.7zip or any other zip utility
2.Stock Firmware
3.MagicISO
4.Nothing else
Tutorial:
1.Start off by downloading a stock firmware,for this guide,we assume its DDKQ8
2.You will get 2 files, S5830DDKQ8_<bla bla>.tar.md5 and SS_DL.dll
3.Ignore the second file,we only need the first file which has an extension of .md5
4.Now its not possible to extract the file with the current extension.
5.So,rename the file S5830DDKQ8_<bla bla>.tar.md5 to S5830DDKQ8_<bla bla>.tar
6.Now,the file is extractable,so extract it.
7.You will get approx. 9 files: arm11 boot,amss,csc.rfs and various others.
8.Delete all the files except boot.img and system.rfs.These are the only files we need.
9.Now,using MagicISO,open up system.rfs and extract it.
10.Make a new folder named Rom_working
11.Now,move the boot.img there
12.Make a folder called system
13.Move all contents of system.rfs to this this folder.
14.Now all you need is a META-INF folder to complete the rom.(Unless you messed up)
Thats it! Pretty easy huh,this is something really basic,but a few people get confused on extracting it anyway.Its just meant to be a basic guides for those people.If you want to get more info on making a rom,refer this guide which i wrote a few months ago.Hope this helped you guys out.
NOTE: I am not responsible if you mess up your phone or w/e happens to it.Btw,<bla bla> stands for the rest of the filename ​

Where do we get a META-INF folder?
Do we use CWM recovery to restore with the new folder?

You can get a META-INF folder by creating one yourself
I don't understand your 2nd question though

Make one yourself,refer other stock roms for the path,then get the update binaries and script from BlackHawk (if stock ONLY).

Kernel is in boot.img. If u want to change kernel, you should change the boot.img

Hmm is it possible to extract a stock ROM from the phone itself? Or not extract but get the stock ROM as zip (with those md5 files, etc) so that it can be flashed via Odin on another phone?
It's because i can't find anywhere to download the stock ROM i had...

For Odin flash,refer freeyourandroid.com.
For CWM flash,take updater script and binary from Blackhawk and put it in your rom
