Solution One, system failure
1, sometimes the jailbreak is not successful, may be with the current system has a certain relationship, leading to jailbreak tool software can not work properly. If this is the case, try restarting the computer first and then escaping.
2, if the restart of the computer is still not a normal escape, you can change the computer to try, this can solve the system problems caused the escape is unsuccessful.
Solution Two, restore the firmware for mobile phone
1, if the above method is tried, still not good words. Because of the previous use of jailbreak tools to make changes to the phone, which is the cause of the unsuccessful escape. We can then restore the phone to the firmware, and then break out again. For how to recover the firmware
2, then we need to put the device into the recovery mode
First, press the power button to boot, when the screen will appear Apple logo, do not release the power button
Second, and then hold down the main screen home button until the screen is black screen.
Third, when the screen is black, please release the power button, the main screen home button do not release until the computer side of ITunes detected a recovery mode of the IPhone
Note: If the recovery mode is unsuccessful, then shut down, try a few more times, familiar.
3. Next, press and hold the "option" button on the keyboard, then click the "Restore" buttons, as shown in the picture
Note: If it is a Windows system, hold down the SHIFT key on your keyboard and click the Restore button, as shown in the picture
4, then select the iOS7.0.4 firmware, as shown in the figure
5, then ITunes will prompt us, to the Apple Update Server for verification, click the "Restore" button to continue, as shown in the picture
6, the last wait for ITunes to restore the firmware to the device, after the recovery is complete, reactivate the device can be.
I am very sorry to tell you that if you fail to recover the firmware after the escape, your phone is back to the factory set up, all the data on the phone is lost oh, just like you buy a new phone like new Oh.
