Greetings everyone. I have a Sony DW-Q58A laptop DVD-RW. When i bought it a year ago i believe it came with UYS2 firmware. Everything worked hunky dorey! Then I updated it to the blasted UYS3 version and everything went pear shaped ! Now it won’t write on certain DVDs and won’t play DVDs with it played before! Is there any way to back flash safely? Where can I get these software? Many thanks for your help guys!
