  • Dude relax.. Just press sleep+home until screen goes black. Wait 3 sec and release sleep button. This is called DFU mode Keep holding home the whole time. Now click ready to jail break and click jailbreak. Run gp as admin or root in mac.

  • If you got stuck in DFU MODE you can use tinyumbrella to kick out of recovery or use sleep+home until your iPhone reboots.

Good luck~ w11z

Your phone might probably be stuck on DFU. Try to DL Recboot it will kick your device out of DFU or Recovery mode. You can also use Tinyumbrella for that.

Plug into the pc/mac Hold Home + Sleep until you see the apple logo. if the phone boots then try to jailbreak again. if it shows the connect to itunes icon then Open itunes and restore.
