Page 1 of philips 712 What am I doing wrong ?

I am trying to change my 712 to multi region using the 750 hack.I have a 4in 1 remote i press the magic button until led flashes twice key in 0539 it flashes twice to confirm.I open the tray enter 085 with 4into1 remote and nothing happens! no 11 spaces, can anybody tell me what I have missed ? Any help would be appreciated,

is it the new digital remote and not the standard remote, check the instruction booklet for dvd codes, if they are not in the book you will need the digital remote model number urc 7541

hope this helps

Thanks wonder was using an older 4in1 the urc 7541 did the trick !
