Complete noob here, any help will be appreciated.
It will only update from an official full firmware image, where critical files are not modified. A demo firmware image does not work. You must flash full debricking repair images using the internal serial port. Then updates will succeed. Search for "DXG" in the simple debricking thread first post for links to success reports and how others did that.
