Region changer changing expert Sony Blu-Ray players

[anthony72]

Hi I would like to know if there are any hacks for changing the regions in setup with Sony Blu-rays players via using the remote control pressing a bunch of buttons in setup where it allows you to change the region. As have tried other software where it allows say to access apps if installed but it will not install as only has apps for this country region. Model BDP-S6500.

Any help would be great.

Thanks
