Hello. I’m thinking a list of drives with known firmwares (good and bad) would be a good idea, especially now that LG is trying to trick people into downgrading by upgrading, so to speak. Here’s what I have. This list also covers certified drives, which I suppose could get patched at some point to defeat DeUHD or future tools.
Note that, as of Dec. 2017, LG started manufacturing drives containing bad firmware. The drives started showing up in stores the following month. It may be necessary to either find a brick-and-mortar shop (e.g., Fry’s or Micro Center) and inspect the stock they have, or use some techno-black magic to downgrade the firmware on drives with bad factory-installed firmware. Patched Asus drives haven’t shown up as of Jan. 2018 but it’s likely they’ll start to show up as of Feb/Mar 2018. If you receive such a drive, look up the “DOSFlash” recovery method. You’ll need to flash the firmware and laser calibration data but your drive will be successfully downgraded.
