Whenever you jailbreak your iDevice you are opening it to a whole new world of diverse applications that are not certified by Apple. Unfortunately this opens you up to a few small risks. You may download an application that just will not work on your device and will actually cause it to turn in to a brick. Creatively in the jailbreak community we call this an iBrick. iBrick is a term used for a completely unusable device.
If this unfortunate senario does happen to you then you will have to reset you iDevice. However in some cases this will still not resolve the iBrick issue and your device will remain unusable. In this case you will have to perform a full restore via iTunes.
Performing a full restore will remove all photos, contacts, and other information from your iPhone. You’ll also need to re-jailbreak it. This is why it is important to keep an up to date back up of your device.
1 – Connect the iDevice USB cable into your computer (do not plug the USB into the device just yet)
2 – Perform a power reboot by holding the power button and the home button simultaneously. Release the buttons once the screen goes black.
3 - Now connect your iDevice to the USB (which should be already connected to the computer) hold down the ‘Home’ button while you connect the USB. Keep holding the ‘Home’ button until you can see the ‘Connect to iTunes’ on the screen.
4 – If it hasn’t opening automatically, open iTunes. You will notice a dialog box will appear, saying, “iTunes has detected an iPhone in recovery mode.” Click “OK.”
5 - Select your iDevice from the Devices tab on the left side of iTunes.
6 - Click “Summary,” button and then then click “Restore.”
7 – Hit “Backup,” then click “Restore.”
Your iPhone will then be restored to its factory default settings.
