Converting Panasonic DVD Player to be Multi-Region

I have a Panasonic DVD player model number DMR-EZ48V.

Does anyone know the procedure / code / hack to convert it to a multi-region player?

No codes can be used anymore in case of Panasonic.

The solution might be to ask for help in a Panasonic service, they have a special remote control/or upgrade disc. In that case it can be done in two seconds. Don’t forget to bring some beer to the service guy.

It usually works. You won’t be the first one to ask for it.

You already have a thread about this topic, so there is no need to open a second one.

So this thread is closed now.
