hey everyone. as i stated my dvd drive isnt working right after my update to 16747. i have a 162ds drive that i have flashed with lt+ 3.0 0251 a couple months ago and then i had to update to the new dash. afterwards it wouldnt let me play any game. i remembered something someone said about having to reflash your drive after updating so i did but i loaded my key and shit up from the dummy files. now all my xbox does when i put a disc in is say play dvd if its retail or unrecognized disc if its a backup. i googled why it says that to them and all i can come up with is i flashed the wwong key. but i pulled it up and even reflashed it with my stock key and everything was matching. does anyone know if they sometimes change dvd keys when updating? or if not does anyone have any ideas. it is a brand new laser i replaced bout a month ago and even tried pot tweak to see if it fixed it but to no avail. thanks in advance guys.
