DVR-104 firmware



Hi Guys,

I really need your help. I use the Pioneer DVR-104 with the new 4x media. For some reason it won’t read any my DVDs. Just found out that I must upgrade the firmware to 1.4 something first, but I was too late. Is there any program I can do a reverse for firmware to 1.2 ? I already updated it to the latest but still won’t read my dvds.
Any help will be great.:confused:

You can email me at



There isn’t really a reason to downgrade back to an older firmware. What kind of discs is it unable to read?


If you wrote to 4x media with an obsolete firmware, then you fried your drive’s laser and maybe even the PUH, due to a severe firmware bug.

Ask Pioneer if they replace the drive…
