what phone? usually the "dd" command works since its low level copying.
usage is:
#dd if=/system of=/sdcard/system.img

it may take a while.

get ahold of a unyaffs.exe, place the boot.img in the folder, and voila.

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:
--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.

--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

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

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)

Don't mean to make you look noobish but have you set the directory in command prompt to where the .jar file is saved before executing sgs2toext4.jar?

Java runtime is missing, you need to install it first.

Try with Minimal ADB & Fastboot... Default ADB & Fastboot cannot flash large files...
it just failed.

Even with Minimal AFB & Fastboot?
That shouldn't happen..
Put the system.img in Minimal ADB & Fastboot folder (C:/Program Files (x86) / Minimal ADB & Fastboot) and then try to flash.. That should do the job...
i'll tell later, this worked or not. thanks
Now i tested, it also failed. but no problem.
i just flashed the whole update.app.
but curious, how to modify system.img and make flashable zip of rom.
I'm trying to modify ramdisk from a boot.img file. But when I use Zenfone-boot-tools from @Shakalaka, the "ramdisk.cpio.gz" file that I get can not be decompressed.
When I use gzip (in Linux), it said that the file is not gzip format.
Could anyone help me please?

You could try this not sure if it work haven't tried yet use terminal emulator
Run this first and it will list your img you want
ls -al /dev/block/platform/soc/1da4000.usfhc/by-name
dd if=/dev/block/platform/soc/1da4000.ufshc/by-name (the img you want) of=/sdcard/ (your img)
You can use this command to dump any partition updated command

If you flash the stock restore from invisiblek yes the a and b img should be the same, I think not positive not much knowledge on a and b partitions. But what I got from invisiblek's post is that is correct.

I'm sure I get the boot.img. do you know which is/are bootloader.img?
I accidentally flashed persist partition on another phone.
As a result, all sensors are not working now.
I haven't backed up that partition.???
Therefore i would like to ask someone to backup persist partition and share the image file with me.
