PIONEER BDR-209 UHD 4K support(flash?)

[HomeKino1337]

Hi!

I am new here.
And i wonder if there is a way to flash PIONEER BDR-209.
It's an external drive from Asus. I can't get it to work with any 4K UHD movie. It says no disc inserted.

Is it possible to maybe flash it?
Can it still rip from regular Blu-Ray discs after a flash?
