As far as I know, the only changes made in the last few firmware updates put out by LG are to do the following:
- Prevent downgrades
- Attempt to kill off LibreDrive
- Implement the ‘requirement’ of ‘encrypted’ firmware updates
Mike has removed those restrictions in the MK firmware. You could, I suppose, update to the latest MK version, but there is really no need. I’d agree with virtually everyone else here in saying leave it alone!
I’m sure if there were any compelling reasons to update, such as media compatibility fixes, Mike would spot it and would advise people to upgrade.
