Just seen it in the firmware forum :
It’s on this Hong Kong site apparently since May.
They present it as “Liteon DVD LTD-165H Region code free tool”
but I tried it on my 163 and it works too.
“Ein” who found it and posted it in the firmware forum has successfully tried it on his 165H drive. He says he had to set the win 98 compatibility mode on his winxp pro to get it to work.
No need for dos mode, no command line, don’t even have to know where your drive is on the IDE…
