LG DR7800 blocked

Hi everyone,

i have a big problem with mt Lg Dr7800.

this evening i have put in a non initialized DVD+RW, i don’t remember what was on that DVD (i think bootable software to recover data on a PC)

I was waiting for the message “initialize disk” but suddenly it display my firmware version and automaticly it has started a software upgrade.

Obviously an that DVD there wasn’t any software update…

Now i have my reader blocked with the dvd in and on the display is says “plase wait”.

I can turn it off, but when on it says again “plase wait”

Is there any method to unblock it? maybe with a DVD with the firmware on (also an old one)

Thanks
