I have a WH14NS40 that I thought was too old to be a NS50 model, but after opening up my case and checking the label, sure enough, it's a 50. So I plan to flash LibreDrive support onto it, but I noticed multiple versions of that drive's firmware have been posted here recently.

I have a desktop computer that is running the latest windows 10 Pro. With the following specs: Windows 10 Pro - Build 10586. Motherboard: Gigabyte GA-78LMT-USB3. Processor: AMD FX 6350. Graphics card: Radeon HD6670. The issue is with my Bluray burner, an LG WH14NS40 and this is the second one I bought that still gives.

Billycar11's pack with the patched flash utility includes a 1.02 firmware per this post:

But then Mike's more recent master firmware collection has a 1.03 file:

Lg Wh14ns40 Downgrade Firmware

Should I go with the 1.03 version? I had thought the point was to revert to 1.02, before LG locked out the UHD capabilities, but maybe I'm missing something. Can someone explain what the difference is between the two files?

As a follow-up question, I really only want LibreDrive support to disable the 'SilentPlay' speed lock on this drive, so I can rip my 1080p discs at full speed (I don't plan to rip any 4k discs anytime soon). My understanding from looking around the forums is that speed limitations haven't been addressed in any of the LD firmwares yet. Is that accurate? And if so, is there any other benefit for me to do the flash right now, other than the UHD read capabilities? Or should I just wait till a version is available that takes off the speed lock?
