and to answer guy above me there is no soldering involved on an xbox if you are only replacing mechanical parts in this case from what i see from the tutorial it left out the bit of swapping a motherboard but if you are just getting the issues with the drive now refrain from taking it apart and or misplacing the drive beause more then likely the board on the blueray drive is still good wich means should just be an optical replacement not to much more difficult and you would not have to swap motherboard on main unit again thanks fixit team!
i would defenitly say when you start having read issues with these blueray drives just spend the 30 $ by the optical laser and replace it . will brobably end up saving you 40 on a new board from what i know and ive seen the boards are still encoded together. and thanks fixit my repair was 100 % succesfull great part clean nicely packaged couldnt ask for more. tbh if you are a begginer to xbox teardowns etc the drive is not the place to start i have torn mine down and rebuilt it like 6 times swapping hhds with ssds etc and the drive was a little more complicated and delicate when you dive into it
