[GUIDE] Unpack system.new.dat

[adomol]

I've been struggling with these system.new.dat block images since lollipop came out. I searched high and low for a way to mount that image outside of twrp with no luck. So I just used twrp instead... These are the steps I take:

1. Clean flash a lollipop rom that has a system.new.dat image in twrp.
2. Reboot system.
3. When device finishes booting use hardware power button to power down without messing with the rom itself yet so it stays fresh. (It's ok to confirm power down on touch screen.)
4. In twrp make a backup of only the system partition.
5. Boot back to system and use the method you prefer to move the file system.ext4.win from:
   
   /TWRP/BACKUPS/-ur-device-serial/-ur-backup-date
   
   to your pc and rename it system.tar so you can unpack it. (Of course make sure you have the proper decompression tools, which every OS usually does now.)

Now you have the complete fresh contents of /system as you would in a traditional rom zip. You can do with that as you please, or just throw it into a rom kitchen. :silly:

There is also another solution to allow you to unpack and repack the system.new.dat file. See the link below.

Quite tricky but still The way.
Thanx!
