Two things on this: Everyone has the exact same device with same soft and hardware (except for the wifi chip wich is in this case not interesting) -> if something works for someone it will work for everyone. Why this does not happen is because many guys here are not very skilled in linux and common tasks on the pc. So either wait for a proper release or try to learn something about bash / ssh and the chmod command. In this particular case, if you unpack the opk to the external sd you don't need to chmod+x on the internal sd you need to change rights. Search on the forum about that.
