I'm with 'beyond repair' above me. That said if your time and efforts are free to you, you have only the cost of parts to worry about. I would recommend a limited approach, as the salt walter tells me 'reliable' may not be in it's future if it works at all. My definition of limited approach- try the battery. If that does not work, STOP. One could go down the rabbit hole on this one, buying part after part, until you were better off just getting a cheap 3GS.
