Baud Rate of Port and Modem are not matching in XBee S2

i am using xbee s2 , now i think its bricked because when i connect it with my computer in XCTU and when i select the COM port to which it is connected it shows me a dialog box indicating that “I have to reset it”

even after resetting it shows me error that Booloader not responding

when i had done the same procedure in Older version of XCTU it shows
“Modem Type… OK , Baud rate of Port and Modem are different”

… Plz help me out any help will be appreciated

Which version of xctu are you working with? How are you connecting the radio to the PC? On what board are you mounting the radio on?
