Repairing the device software
If you forget your screen unlock password, PIN or pattern, you can use the device
repair feature in Xperia™ Companion to erase the security layer. You need to provide
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.
To repair the device software using Xperia™ Companion
Before performing a software repair, make sure you know your Google™ account username
and password. Depending on your security settings, you may need to enter them in order to
