2. It is also possible that there is no display when the jailbreak fails, please plug your phone into the computer to see if there are any prompts.

Scenario 2: A debug device that is identified as DFU mode is prompted. In this case, press and hold the home button and the power button, which will usually automatically turn on and enter recovery mode after a period of time. Use a small umbrella to exit the mode.

If the screen does not light up after these 2 steps, it will enter DFU mode, and then you can use iTunes or other flashing software to restore or re-flash the computer.

Method 2: If method 1 is invalid, you can try to connect to the computer, the first step is to use the "restart" function in PP assistant, itools and other tools, if it is successful, congratulations, if it is not successful, you can proceed to the next step.
