Relock bootloader on HBOOT 1.54
I'm currently running pure stock 4.2.2, never rooted, never s-offed, never unlocked bootloader. As it is now possible to S-OFF using rumrunner s-off, my question is whether I'll be able to re-lock my bootloader without any evidence of unlocking it through HTCDev. I know it is possible to do with revone tool, but that only works on 1.44 Hboot. As far as I know, I should be able to downgrade Hboot after obtaining S-OFF with rumrunner, but I'm not sure.
TLDR : I want to unlock bootloader on 4.2.2 using HTCDev, can I get it back to state "Locked" then ? Any guide ?
