I made a simple debloat script for 2012 Variants that are still running on 4.1.2. But will be working out soon with 4.3 once the official update from Sony comes out.
Just flash the zip via CWM (not yet tested for TWRP). No fancy graphics on this.
Credits goes to DaRk-L0rD for making the tutorial so simple and easy to follow.
