Same firmware would not update

I have been attempting to update my firmware, and I have even rolled it back. No matter what version I am using, when I try to update “update.lcd,” i get the error message “same firmware would not update”>

I do not know how to proceed. Can someone explain what I am doing incorrectly, please?

I am updating to v211.
