I love the idea of lightscribe, but the problems it brings are impressive. I first bought an OEM HP Lightscribe burner...it was crap and I trashed it. Then I bought a Retail HP DVD740B Lightscribe burner. It will burn DVD lightscribe just fine, but NOT CD. I'm wanting to update to some newer firmware. I've found some HJ24 firmware on the HP site, but that's it. From what I've been reading this is an LG drive. It's true model number is GCA-4166B. I've pulled down the 1.02 drivers for this to flash and reload the firmware but I keep getting the "Model Mismatch" error. Any help? Please??
