Hello
I'm trying to Relock bootloader after it has been unlock with fastboot oem unlock command, and it seems an impossible mission.... I've downgraded to stock version thru EMMA FlashTool (Android 9).
The command I use is: fastboot oem lock and I get the following error:
FAILED (remote: 'unknown command')
fastboot: error: Command failed

Also tried thru sony mobile flasher by androxyde (Pressed BLU button):
Cannot invoke "String.split(String)" because the return value of "java.util.Properties.getProperty(String)" is null

Any suggestion anyone??

It's not possible to relock the bootloader of the XZ1C. It's a one-way operation. All of the threads giving information on how unlock mention this fact, as (I believe) does the Sony unlock pages.

Thus why you're getting an unknown command ... because there's no such action supported.

I've installed kernel-G8441-47.2.A.11.228-hideunlock.zip and it works great!
One thing I can't pass - Google Wallet (Pay)
I didn't root my device, only unlocked the bootloader.
Any advice?
