Need to restore firmware before returning LG WH14NS40

[samungan]

I originally picked up a blu ray and a USB player. I was only able to rip episode 1 from the first disc and all the rest failed. Thought the cheap USB player was bad but turns out disc 1/4 was bad. The old cheap USB drive works perfectly but the LG drive is a piece of trash since I must've gotten a faulty unit. Already flashed it and want to restore it back before returning.

you may or may or may not need to flash to your correct model but its the same way you already flashed it just choose the other fw and use the LG tool
