Hi,

Has anyone been able to successfully relock their bootloader after erasing and flashing stock firmware?

The fastboot command "fastboot oem lock" returns:

"FAILED (remote: 'Command not supported in default implementation')
fastboot: error: Command failed"

Maybe you reboot on wrong fastboot mode, or Try use latest adb fastboot
Unfortunately I think Sony my have blocked the ability to relock the bootloader :(

I am using latest 'platform-tools_r33.0.3-windows' and I've also installed specific Sony fastboot driver from Sony Developers.

I am booting into default 'fastbootd' mode.

Yes that is correct, it seems that Sony have sealed up the ability to relock ourselves :(
