Page 1 of Need region crack for Philips DVDR77

I need help to hack my DVDR77. I need to turn it into multi region or at least be able to switch between region 1 and 2.

I have tried typing <play> 159 but that only changed to channel 9.

I also tried to open the tray and type 0 5 times as descrived the the DVDR75 thread. As soon as I typed the first 0 it just closed the tray.

Thanks in advance.
