[GUIDE] Noobs guide to extract Galaxy S3 stock firmware(.img) !!

Hi all !!
We now have the stock I9300XXALE8 firmware of Samsung Galaxy S III.
Download here - thread
So, if you had downloaded it and wanted to view stock the apps & something like that, you need to extract the system.img.

Pre-requisites:
* 7-zip

PROCEDURE:

Quote:

--When you extract the ROM .zip , you'll find 3 .md5 files. With help of 7-zip, extract each of the .md5 file. When extracting the .md5 file, 7-zip may show some error, but you can neglect that and continue extracting.

Quote:

--When you have completed extracting all of them, you'll find many files including many .img files. For Apps you need to extract system.img. Unlike normal nandroid backup's system.img file which in yaffs, this stock one in different. So, unyaffs tool can't unpack the system.img

Quote:

--To extract the system.img, download this tool: sgs2toext4 (created by drphrozen). On extracting it you'll have sgs2toext4.jar file.

Quote:

--Open a command window and set the directory where you have .jar file.

Quote:

--Now type sgs2toext4.jar and press enter.

Quote:

--The .jar will run in a new window & will ask you to drag & drop the system.img file there. Do the same and wait till the process completes.

Quote:

--When the process completes, you'll find a file named system.ext4.img in the same folder where you had the system.img file.

Quote:

--Now download Diskinternals Linux Reader and install it. Then open the program --->> Drives --> Mount Image --> select system.ext4.img > Mount

Quote:

--It will show you all its contents. Now select all the things displayed --> right click --> save and select a folder to save them. There you'll find the extracted system.img !!!

You can try extracting cache,data,boot.img with the same method.

If you want to de-odex the rom, try using AutoDeoTool(created by xavierjohn22 - thread)
