iPhone 4 stuck on black screen after Jailbreaking with Cydia I have an iPhone 4, jailbroken, and running iOS 7.1.2. I opened the Cydia app, it appeared to be loading something so I waited. Then the screen turned black. I can still hear sounds such as the charging tone when you plug your iPhone in to your PC and things like that. A few posts have recommended doing some Lock Button and Home Button combo but my lock button is broken and doesn't work.

I can't seem to restore because Find My iPhone is enabled and I need to disable it to be able to restore.

Is there any way I can restore this phone and remove Cydia?
Try downloading redsn0w and creating a DFU mode IPSW. Restore the IPSW with iTunes. Now that your phone is in DFU mode, you can totally wipe the iPhone and restore.

You can download redsn0w here.
