hi

i appreciate it , if someone can tell me the way to downgrade my fmb640 from the latest firmware 01.02.27.rev.06 that stop works after a while , to the previous 01.00.05 because when i try to downgraded it i take an error message ( possibly they have protection from a downgrade to the old FW after they had been updated to newer )
