How to enter keys in Golden Interstar

[boldlygoes]

I have a Golden Interstar GI S770 receiver but I cant access the menu to enter new codes, keys etc.
Using the remote control I press menu, instalation, enter 4 digit pin code but I cant get any further to enter new codes.
Does anyone have a step by step to get into the section for entering codes.

I have found the solution.
The receiver has been flashed/upgraded and it is just a case of pressing 0 then the 4 digit code and the menu for entering the keys.codes appears.
what I was doing wrong before was that I was pressing menu and then trying to get into the system from there.
