Hello, I have a Xperia Z1 with software build number 14.1.G.2.257, the boot loader is locked. I did not make any changes to the system. I have set a 6 digit pin. When I try to make a system encryption I get asked for the pin, then phone restarts and nothing more happens. No encryption was done. What is wrong there? Why does the phone´s encryption option not work!?
Now it works! I have disabled the option "visible passwords" (may not be the correct name, I do not use the English interface). After changing that option, encryption starts now!
