Sorry for being a rookie. I have the 3.55 firmware and have heard, that its important to keep it that way. Otherwise it's hard to remarry it. Can i just update my firmware and then it automatically accepts my new bluray drive?
You need 3.55 , and if you have QA enabled and marked in QA options debug update "ON" then is simple as sticking usb with as example rebug 3.55.4 and you can save it to your hdd so it can be stored on hdd no need for usb stick next time.
Otherwise you need version .999 that patches your syscon and needs dehashing
