Help with LiteOn LTR-24102B firmware

I recently flashed my Lite-on DVD drive to get rid of reigon locking. However, afterwards, my burner LiteOn LTR-24102B didn’t work ne more - it kept spitting out CD’s as soon as i put them in so i updated the firmware for my burner to 5S5A (it used to be 5SOD, now it doesn’t spit out CD’s, but it just doesn’t recognize them at all. Can someone tell me how i can fix this problem?
