[Q] How to cause emergency shutdown
Phones like Xperia S/SL has got non-removable batteries. Well, in case of bootloop, SOD or screen freeze appears during reboot, what can I do? For other devices, I could have pulled out the battery to shut down the phone, then plug the battery again and do something else (like entering fastboot/cwm) etc. But I can't do the same in SL/S, and that's why I am very afraid to flash any ROMS/test kernels etc.
There must be a way, please help me.
