PX-708A 1.06 how to go back

Well I tried reflashing with 1.04 and still had problems. Seems if you want to go back first flash with 1.03 than reflash back to version you wish to use. Seems anything later than the 1.03 does not completely clear out all updates to the firmware that 1.06 seems to have done. You will usually have the drive re-detected by the operating system when going back to 1.03. Now I’m back to being able to have my DVD’s detect and read properly without having to repeatedly eject dvd and try try again.
