I turned on the phone and went to play poker with friends :d
But as soon as I had time for the beauty, I backed up TA, flashed unbranded 314, rooted, xposed some, adfreed some, dual recovered the phone and I'm done. Just need to remove some bloat maybe. Had CM11 on my GS3 but damn, for now the Sony rom is so smooth and packed with nice features I don't want to lose them to install AOSP which is great and quick but boring in my opinion. Maybe in a year or a year and a half if Z2 doesn't get updates too quickly I will swap for Cyanogenmod.
Bootloader stays locked for now.
