Unlock Bootloader (Read-only)

LG V20 US996 Cannot unlock bootloader?
I'm trying to unlock bootloader on my US996 LG V20 (Factory Unlocked) and I'm getting a message that my IMEI and Device ID do not match. This phone has never been touched by anyone else other than me and I bought this device new. I've never tried to unlock the bootloader until today. I do not know why this is happening. I copied the codes exactly as specified and it still says it's "unmatched".
