Question Sony UBP x700 player not region free as stated

[Metalrocks]

I recently got the mentioned player as I kept reading that it's region free.
Player as such runs great and all, but I have a few Blurays from other regions and sadly I keep getting the message that it's restricted to this particular region. I live in Australia, so therefor it would be region B.

I've looked up online how to fix it, from various forums to Sony forums to videos and all of them said that you need to press the coloured buttons on the remote with the tray out. Apparently the yellow button is region A. Red is region B, etc.
I've tried all 4 colours, but sadly to no avail.

DVD's as such run fine. No problems. And I got from Europe, to Asia, to US and obviously AUS.

Am I doing something wrong? Not even the instructions tell me what do. I deliberately got the player because it was stated on being region free.

I have one of those; I checked the specs and I do not see any indication that it is supposed to be region free. Where did you see it say that it is supposed to be region free? Only if a disc has a symbol on it indicating that the disc is playable in all 3 ABC regions would the player be expected to play it. Otherwise the region indicated on the disk must match the region indicated on the back of the player. And the region cannot be changed. Only UHD 4K blu-ray disks are region free.
