Trying to unlock bootloader on xperia z3 compact but it will not allow me to update the driver for the s1 usb in the device manager. It indicates something about the 'hash' code.

Anyways, tried windows update patch ---wouldn't install. Tried flashtools and I am unable to download the current version that supports z3 due to my antivirus. I just want to be able to flash to another software version since lollipop is not working correctly. I received the code from sonymobile.com to unlock bootloader. Any help would be appreciated.
