Looks like I am having the same problem... and nothing works.
/netflash -scan works fine (and returns A: as the device), but then, when I do the /netflash -flash 3ape_auto.bin A: (or _fast.bin or _rpc1.bin) all I get, after answering "Y" is: "Error opening firmware file"
.. and if I try netflash -flash 3ape_orig.bin A: I get "Error opening SCSI device"
When I use DVD info X 3, I get This:
Model: DVD RW AD-5970H
Status: RPC-2 (region locked)
Region: Not set yet
Changes left: 5 Vendor resets left: 4
Fact is, that no matter what DVDs I try to use on this MacBook Pro... I can no longer play them (I have DVDs bought in the USA, UK, Portugal, Italy, Australia, China, etc.) and I use VLC... nothing works...
Am I missing something? Am I doing something wrong?...
Thanks for any possible help!
