Now my a4h work ok. but i have question why??
When i upgrade FW using LtnFlash with sflash and use full backup (before i clean rpc count) drive not recoqnize some dvds.
This FW i Full Read using LtnFlash
But whein i write to A4H full FW from A1H my drive work ok like A1H.
Next step i use Flash Utility and write oryginal QP59 and restart pc....Drive work OK as A4H...i use LTnFlash and full read this FW
Where the problem is??
