Help with pioneer a03

[ditchhopper]

Bought this drive new a year ago and its worked great. A friend sent me a link few weeks ago for a firmware update for burning
with the new 4x media that is out. Updated and since then it wont read or write cd or dvd. Can I roll back to the old firmware somehow? Does anyone have a fix for this? By the way I bought the drive online listed as an ao3 but it says 103 in my hardware
list. I used a a03/103 firmware update. Thanks for any help.
