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

1. Java SDK = Click here to download java
