I tried to crossflash my drive GH22NS70 EX00 to GH24NS70 GH01. I wonder why the official firmware-file GH01 works. Now the drive doesnÂ´t recognise a cd or dvd. Can someone give me a link to the gh22ns70 ex00 firmware? thereÂ´s nothing in google or in this forum. I hope that itÂ´s possible to dump with “flasher.exe”.
