I need to downgrade my DRU 510A (10g) too.
If anyone bought his drive with the 10a Firmware, and flashed it to 10b - and has the 10b Updater still on his computer -->
So pleeeaaassseeee let me - and of course other people who are interested- know.
I bought my drive with the FW 10b - and everything was fine.
Then I updated to 10d and everything was bad !!!!
Not one of my DVD+R Medias was working !! ( the Media that worked on 10b without problems)
I talk about the MMORE 4x DVD+R Media.
The real joke in my situation is that the burning proccess is always successful - but none of them are readable on any drive!!!
The only media that works is the MMORE DVD+RW.
I think about to burn everything on RW media instead of buying a larger thrashcan :rolleyes:
But with the good old Firmware 10b I would try again - so please send it
