Iphone 4s won't turn back on.shows its charging.what gives?

So two days ago my phone died and since than it has turned on twice. It shows that its charging with the red and thunderbolt under it. I brought it to apple and the guy was uselss that helped me. Talked to me for two minutes and tood me i had to pay 200 dollars to fix it. Also told me my warranty is void cause i have cosmetic damage. I can't afford the 200 dollars to fix it right now. I've tried the home button and power button, as well as trying to hold onto the power button and plug it into my computer and nothing.Am i out of luck here? Is there anything i can possibly do?

Yes there's a way first download the IOS vetsion you were using on your iphone then download a software called Redsnow… Latest version will work only… After downloading both. Open redsnow if youre using win 7 right click on redsnow then open as administrator… You see two options in it. Jailbreak and everything else. Open everyting else.( secend option ) click on SELECT IPSW then locate the IOS version you just downloaded… If anything comes up select yes… After that go back to and jusr click on JUST BOOT. Enter DFU mode if it asks to.It'll give you the instrutions… Your phone will boot itself… If this idea don't work. Try restoring your iphone using itunes… Open itunes connect your iphonw using USB cable. Select your iphone in itunes hold SHIFT click on restore button on itunes. Locate the IOS file you just downloaded… Open it. Your phone will restore.It'll take approximately 10 mnts… Then it's done. If your doesn't show up in itunes do this restore thing using redsnow…

Well today I let my iphone die all the way on accident and I plugged it in and it said it was charging, well its been two hours and it still says its charging but it won't turn on and when I unplug the charging cord it says to plug it back in and that the iphone is dying.
