your Google account login details to perform this operation. By running the repair
feature, you reinstall software for your device and you may lose some personal
data in the process.
If your device seems to have frozen, restarts repeatedly or doesn’t start at all after
you’ve updated the Xperia software or after you’ve performed a software repair or
a factory data reset, try forcing the device to shut down then try turning it back on.
If the problem still exists, force the device to shut down then perform a software
repair.
