Pioneer 107 hack firmware question

Heres hoping someone can help me with this question, I updated the firmware in my pioneer107 so i could burn at 8 speed. The update went a ok no problems there and the media was recognised as 8X, Nero burned the media no problems but when i tried to burn with decrypter it failed every burn even if I burnt at 4x. The one thing I do remeber is i flashe it throough windows and didn't reboot the comp before I tried the burn. Does any one think i did something wrong, any help would be most appreciated.
