Can you unbrick an iphone 4s? (After Failed Jailbreak)?

So I tried to jailbreak my Iphone a while back and it bricked. It completely locked up my phone and all it does is show the apple logo. I have tried re-jailbreaking it to un-install the jailbreak but the evasi0n thing wouldnt even recognize that it was connected. So i deleted it off of my computer. I have tried to reboot it through itunes but it didn't work. Any other ways? Or should i sell it for parts? (Brand New Front + Back Glass. Blue Home Button. Good Battery + Good Camera.)

Do you need to do a hard reset:

1.Connect the phone into a computer with iTunes
2.Hold down both power and lock button at the same time.
3.Wait till the screen go black and apple logo appear then let go of powerbuttn but keep holding home button.
4.Wait till the Connect to iTunes screen appear and then go to iTunes and click "Restore iPhone"

If this doesn't work then the phone has a hardware issue(mostly likely faulty logic board)

  • On my iPhone, can't get mail. States connection to server failed? I have changed the password two times in the past three days due to a notice on my cell phone stating my account may have been compromised. This evening three emails came through from Apple on my mobile device, but the notice pops up stating the connection to the server failed on top of the emails. How can this be fixed?
  • IPhone failed jailbreak attemp? I tried to jailbreak my iphone from my friends computer, and now it won't turn on (Stuck on apple logo). I tried to put it in dfu mode and restore it, but i gives me an error and can't do it. It then gave me the option to "Update it to 9.3 (i had 9.2)" so i did that. Nothing. I have insurance on the phone from my carrier, but all i want to do is restore it. If i bring it to an apple store, and just ask them to restore it to factory defaults, will that work?
