I upgraded but it doesnt seem to be working right..the dvd burner doesnt want to read some dvd's. So I thought I would see if I can go back to the original firmware..thanks for any help
There is no way of knowning what the version of the "original" firmware. Someone may be able to help you locate previous versions...but how will you know which one is the original?
Your best bet is to trouble shoot the actual problem you are now having. Most likely it isn't related to your previous or current firmware.
