Hello, i have an Xperia Z Ultra which strangely booted into secured mode and i am not able to turn it off
rebooting doesnt work even reset doesnt do anything. no buttons are stuck so i dont understand why it keeps happening like this. sorry for bad english
no, i meant disabling the save mode, even if i reboot it my phone still is on save mode. even the reset button near the sim tray didnt work
i can restard it as often as i wantt but nothing ever happens. im trying now to repair it via pc companion 
Do you have a protective case? are you certain that there isn't anything pressing on any key?
