@Naugat I'm sorry to hear about your issue but http://developer.sonymobile.com/unlockbootloader/ Voiding the warranty If you unlock the boot loader, you may void the warranty of your device and/or any warranty from your operator. See your device’s warranty statement for details. Additionally, due to the modified device software, Sony’s repair network will likely have to replace key components before it can properly test, repair and verify your device using our repair tools and software. Consequently, if Sony performs a warranty repair, Sony will likely charge you a significant service fee for the additional costs caused by your modification of the software. If I change my mind later on, is there any way to restore my device? No. Once you have unlocked the boot loader, you will not be able to revert the device back to a locked or original state or restore the DRM security keys. You can however use the Flash tool for Xperia™ devices to flash a generic Sony ROM, although it will not receive automatic software upgrades.
