This is a thread on how to unpack and repack the system.img.dat file of your Android Rom,to see its content.


Starting from Android 5.x (Lollipop) Custom roms are not compressed like on previous android versions. Earlier all Files were inside the /system folder.And we were able to see all the system files
The problem started in >=5.0 versions because rom size increased and it was necessary to highly compress them again.

You Must Have Following Files Installed in your PC

The rom that I had, only had system.img boot.img and those older folders. It didnt have file_contexts. But later I extracted it from boot.img and it worked thanks anyway.

Still unable to repack the dat.
Windows says rimg2sdat is not a valid Win32 application.
It works under Windows 7 at work but not under Windows XP Pro like I have at home.

Someone got another version? Is there a XP compatible version of rimg2sdat?
Thanks
