Many products have all sorts of undocumented functions for the use of Factory technicians. It is unwise to fiddle with these if you do not know what you are doing.
But, as far as I can see, the Eclipse does not have anything fatal with which you can fiddle. So, my advice would be to follow the Web Site UPDATE instructions and see if you can bring it back to life. If not, it will have to go in for service.
