For that, you need to get into bootloader. Using fastboot, issue the command:
fastboot oem lock
But, one more thing - before you try this, are you able to get into your phone at all? Have you tried the factory reset in settings? If possible, try that first, before you lock your bootloader & run RUU.
If you do run RUU, after your system has become stable, to unlock it back, follow the instructions in "Unlock Bootloader" in htcdev.com
If you think I've helped you, then you'd be doing me a favour by hitting the Thanks button..!!
