No. It shouldn't fail. You're probably trying to flash the entire firmware package. THAT won't work. You need to flash the modem related files ONLY

There is no locked bootloader...only a secured one. Every L720 I've had to unlock never failed the MDC flash in Odin. Are you SURE you have the MDC modem and are you SURE you have an L720? Check the sticker in the back and in download mode it tells you the model.

THAT might be why! Let's move into the present and try it on Odin 3.07 or 3.09 (I personally use 3.09 all the time because...well its the most recent one).
