[M_J_Nazari]

Hi , please someone describe where the 2764Mb is coming from?

make_ext4fs -s -l 2764M -a system /sdcard/system.img /system

i searched for partition table for i9500 but cant find this number

lrwxrwxrwx root root 2013-03-26 16:07 SYSTEM -> /dev/block/mmcblk0p20

************************
major   minor  #blocks    name
259       12    2830336    mmcblk0p20
************************

Hi

When you unpack system.img, the size of 'system.img' in output file = 2898264064 bytes.

Now convert to megabytes. 1024 bytes= 1 kilobytes, and 1024 kilobytes= 1 megabytes.

Size of filesystem= 2898264064/1024/1024=2764M.

finally i made the system.img from my phone and it boots correctly , but there is no permissions for some files like su.
I tried another way to make system.img from linux but no success too , as i checked the problem it caused by file permission problem, it seems many files have not correct permissions, phone stays on samsung logo ( 2nd logo ), tried to catch the logcat, but i cant access too, this is the message, any idea please?

M:\>adb logcat
- exec '/system/bin/sh' failed: Permission denied (13) -

I know this thread is about S4 but I want to inform you that the Chainfire's bloating tool works also for Galaxy Young 2. Many thanks, Chainfire.

I ran across this and this is awesome.
I have a rooted s8 sm-g950u
Would this work? What changes to the commands would have to be made?
