Hi. You are just wasting your time on the unit. 
Old cif recorder with damaged software ..... firmware will not recover it. 

DVRs are cheap. Look for a new 4 in 1  dvr

i want to recover it if is old...we don't have to throw everything away

Your right you don’t have to throw it away

use it as a paperweight or a doorstop 


firmware is useless if the software has failed 

It’s over 10 years old
