TS16, wont update, Firmware Version 82000684_D 06/03/2002, boot 82000685_C 04/09/2002

trying to update firmware, instructions for hardware 50001207-01 G do not seem to work
first no POST update on menu, online instruction says goto firmware update and select POST file. Do that USING 82000685_G and message returned bad image, reloaded bin file again from website, this should be the POST before doing firmware
Tried 5 x, last time it appeared to “work”, no error, click on ts16, then rebooted
Now no access or response to search utility
Did I just create a brick
