Hi, everyone !
I was playing with cisco-1720 router, changed some firewall rules, overwrote flash and it was working fine. But when I rebooted it for the first time I got an error:

" loadprog: bad file magic number:	0x0
  boot:  cannot load "flash"			"

after pressing "enter" I get  "rommon1>" prompt. I guess I have to restore flash memory.
I don't know even how to start and where to find the information.
Please, help !!!
