OEM unlocking

[jekennedy]

Hello,

I have a brand new Xperia XZ1 Compact (G8441) and I'm setting out to install LineageOS on it.

I understand the first step is to unlock the bootloader. I have followed Sony's instructions here but I get this error when I run the fastboot unlock command:
./fastboot oem unlock 0xE8475F4F6417A194B (I also tried without the 0x)
FAILED (remote: 'Incorrect format for unlock data')

I then tried following a different article at getdroidtips but I get this error:
./fastboot -i 0x0fce oem unlock 0xE8475F4F6417A194B
fastboot: invalid option -- i

I'm also confused if I even have to run the above commands because I managed to enable "OEM Unlock" from the Developer options menu. This OEM Unlock option wasn't initially visible when I first enabled Developer Options so I'm curious why it suddenly appeared.

Any help would be greatly appreciated, thank you!

I was able to get it to work on a windows machine, after installing this:
