Page 1 of hack for duraband portable dvd-1002

I posted a request for help with a hack for this model on 12th April. I`ve had a reply but my remote doesn`t have an open/close button or a clear button.
The remote is a tiny thing and limited in functions. The open/close is a mechanical button on top of the unit.
I`ve tried the most recent reply but this hack didn`t work either.

Does anyone out there have this model and have successfully hacked it??
