Stuck on lockscreen after jailbreaking with Pangu?

I jailbroke it yesterday morning and when i try to unlock (i have no passcode) i can see my home screen wallpaper but no apps or anything. Then after a few seconds it reboots and the cycle continues. I have an iPhone 4. Please Help!

Added (1). I've also done the light and earphone trick, but nothing works!

Try to point a flashlight to your phone and see if it works.

  • Pangu says already jailbroken? I downloaded Pangu and had Cydia on my iPhone but I deleted it. I want to re download it but whenever I try to jailbreak with Pangu, it says iphone already jailbreak. How can I fix this?!

  • My iPhone is stuck on the reboot logo while jailbreaking? Device: iPhone 4s Software: iOS 7.0 I was jailbreaking iOS 7 w/ evasion for my phone. The third reboot came up and after a short period of time the apple logo appeared it has stayed there for 8 hours. There's no way I can connect it to my computer because it does not read that the device is there because the device has not fully rebooted. Should I smash the device and use its warranty? Or Do you have a simpler solution?
  • Is jailbreaking my phone using Pangu 9.1 on an iPhone 6s safe? I know that before this jailbreak there was a chance it would damage your phone but on the Pangu website I can't find anything about what can happen if you try to jailbreak it. What could happen to your phone?
