The so-called white apple means that the screen of the mobile phone has kept the picture of the white apple after a certain shutdown or fault restart, which mostly appears on the jailbroken machine.

Don't panic when you meet white apples. First of all, you need to see if it is a serious injury. For example, before the phone suddenly turned white, it fell from a height or fell into the water. In this case, please go to the maintenance station for maintenance service immediately, otherwise it may be impossible to repair because of the long power-on time.

If there is no serious injury, a white apple suddenly appears during the use of the mobile phone and has been unable to turn it on. At this time, you can usually solve the problem once again.

It's not displayed on the screen.

First, this situation mostly occurs in the case of serious injuries, and the most common is falling into the water. Since the iPhone can't pull out the battery, the mobile phone will always be turned on after entering the water. Can only be sent to the maintenance station for repair.

Second, it is also possible that it is not displayed when the prison break fails. Please plug your mobile phone into the computer and see if there are any hints.

In the case of 1, the prompt is unrecognizable, and it is still unrecognizable after replacing the data cable, so the motherboard has failed and iTunes cannot repair it.

Case 2 prompts that the debugging equipment is identified as DFU mode. In this case, press and hold the Home key and the power key for a long time, and it will automatically turn on and enter the recovery mode after a period of time. Use a small umbrella to exit this mode.
