Howto Unlock Sony Xperia XZ2 Compact
Since I wanted to install LineageOS in hopes my touch layer would work properly again, I had to unlock the bootloader first and then flash LineageOS which was fun.
First get the unlock code - https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader and install Android platform tools - adb and fastboot.
Then go to the system, turn on developer section and turn on USB debugging and allow OEM unlock.
