[Q] Z1 freezes when booting
Urgent. My Sony Z1 has rooted .681 version running fine for weeks. But trouble came today I tried to upgrade to .757. I had the flashable zip on the sd card, Booted into recovery mode then did a wipe and factory reset. Then in the installation process of .757, the phone reboots to SONY screen and freezes. I could only use Vol Up + Power button to turn it off. Then the next reboot, still freeze at the 1st second. It's been freezing for 15 minutes. It doesn't even vibrate at the SONY screen, so I cannot enter the XZDualRecovery mode. Please help.
