hola,pues hazle esto y te funcionara.
Use CAS interface to recover it, this way:

Press "Erase all" button
You will get:
"erasing error on block 0"
"erasing error on block 1"
"erasing error on block 2"
After these three messages, press "ESC" and then "Erase all" again

When deleted, then you can normally program your cam
saludos.
