I need the multi region code for a Samsung DVD

Sorry, there isn't one. Your model is not hackable.

The usual Samsung hacks involve using the remote to enter the correct numbers but your model has no number keypad on the remote. Substituting a universal remote also does not work and I've been informed by Samsung that the region coding on this model is hardware encoded just like on many Sony and Panasonic models so you cannot even override the coding using a service centre remote control (I've tried). I discovered this when a friend purchased a large quantity of clearance overstock region 6 DVD H1080's and asked me to convert them for resale in the UK (region 2).

To hack your model requires internal hardware replacement and this is not economically viable.
