Most of us have decided to unlock the bootloader as there is no root or xposed without it.
But as you may have noticed this wipes the masterkey in TA unit 66667 and will make all Sony credentials inaccesible. As a consequence a lot of functionality is lost, e.g x-reality, Sony application updates etc.
Here is a solution to simulate the credentials again. There is no way to recover your lost key, but we can simulate them. Just flash the attached zip via TWRP, that's all.
This is solution is for all Z5 models (Z5 compact, Z5 , Z5 Premium, and the dual models of course)
