I have a Samsung S4 Mini GT-i9195 and recently I've updated it to CyanogenMod 13, it was stuck on Android 4.4.
The /system partition has 1.5GB and it was full with the stock ROM. After updating to CyanogenMod, I got only 600MB occupied and 900MB free. How can I resize the parition to, let's say 800MB, and add the remaining space to the /data partition?
I've found this answer for a very similar question, but I'm not sure if that procedure suits to my phone and I don't know how to create the PIT file. I'm already able to backup it from the phone and edit it with PIT Magic. But I don't know if I can do it with this tool or even how to do it...
