Correct me if I'm wrong. On this thread:

here: Here just some other commands for revone:
-u --> Unlock Bootloader
-l --> Lock Bootloader (It will not simply lock it, it will lock it like it was never unlocked)
-r --> Relock Bootloader (mark the device as unlocked)
-t --> "Tampered" will be removed from bootloader
!!!IMPORTANT! YOU NEED FULLY STOCK ROM, STOCK RECOVERY AND STOCK BOOT BEFORE YOU CAN USE THIS!!! fastboot oem writesecureflag 3 --> restore S-ON
You could restore to S-ON with writesecureflag 3 command. So that means for at&t version htc one mini. You can take the ruu then restore to s-on.
