What to do when your iPhone is in a complete coma?

I have an IPhone 4 and its completely dead. It just doesn't turn on, I'm pretty sure it's not the charging issue. I tried multiple charges with different outlets. I even cleaned the charging slot. The solution is to hold down the off/on button and home button. I tried that but the apple icon isn't popping up. My home button doesn't work, but I cleaned it so it should work if you press hard enough.
Does anyone have any advice, besides getting a new one or taking it to a shop?
I recently took some photos on that phone, but the phone isn't backed up

My Iphone 4s won't restore to factory settings?

My iPhone 4s had been stuck in a continuous reboot loop and the started showing the "apple screen of death." I Held the sleep/wake button until it restarted and continued to hold the home button until it showed the connect to itunes screen. I connected to itunes and it says it must be restored to factory settings. I accepted and then before it even begins to restore a pop up says that it can't be restored because of unknown errror (-39). I have the latest version of itunes. I also have a Windows computer. I don't know what to do at this point.

Lost my iPhone and its dead?

I lost my iPhone 5s the other night and now it's dead. I've tried all the "find my iPhone" app suggestions and it's still dead so it's not online. I only have iOS 7.0.6 so I can't find the previous location. I really need it by today so anything will help. I've destr my house many times now looking for it. I did have people over so I'm wondering if any of them took it, but it just isn't something that seems like any of them would do.
