Hello everyone, 30 minutes ago I tryed to install SRS (root) from Play Store. And I had to restart the phone, but it stuck at booting. I haven't installed a custom recovery and I read that I have to boot at Recovery Mode, but Sony phone don't have built-in recovery.. So anyone could help me to fix this problem. Thanks!
The phone is at 4.1.2 and the latest build number..
