White Apple Solution: Method 1:

When a white apple appears, press and hold the switch + home button, let go of the black screen, and then press power to turn it on, and then wait for a while, at this time it is still a white apple.

Then press the volume to add and subtract, you can click twice, and then long press the two together, note, it's still a white apple.

Then press and hold the switch + home button again, let go of the black screen, and then press power to turn on, this time don't press the volume plus or minus again, if the above steps are not wrong, it should be able to turn on normally. Method 2:

If there is still a white apple, press the power and home together, wait for the black screen, immediately press and hold the power and volume buttons, and then wait for the screen to go black after seeing the white apple.

Finally, press the power button or connect the data cable (the data cable is connected to the computer) and see the booted white apple again, and you can enter the system.

What should I do if my iPhone 4 won't turn on and has been in a white screen state, the steps can be operated through the mobile phone as follows:

In general, if you only encounter a sudden white apple, it may occur when you are currently using some application software. Don't panic at this time, this situation is an occasional failure caused by poor compatibility between the application software and the system. When a white screen appears, the system will automatically restart, and after the boot is completed, it can be unlocked and used normally.

If the white apple has been displayed on the current screen and the screen has been white for a long time, you can try to press the [Home + Power] button at the same time to force restart the iPhone to see if it can solve the problem.

If it's because you've done some special things before the white screen appears, the system may not be able to get up all the time. Usually, unexpected situations during the process of updating your iPhone, or system damage due to jailbreaking, etc., will result in a white apple and a white screen. If you encounter such a problem, you must use a computer to fix the problem.

Don't worry, don't use my method, press and hold the power button and the home button in the middle, press it to turn off automatically, and then wait for 10 minutes to look at the machine again, if it still doesn't work, practice 6163887958 weixin.

It's exactly the same as my previous Apple 3, this is not saved, I used to charge it for a paralyzed day and a night, and then I touched it, it was still the same, no power. So you'd better go to the store, because the online program is useful and useful, but the biggest problem is to turn on the phone first, but we can't get in the electricity, how to turn it on, so it's useless for you to get it yourself, I've tried man

Second, the specific operation and answer method:

This needs to be reflashed. Connect to your computer, enter DFU mode, and open iTunes. Point recovery.

The premise is that iTunes is upgraded to the latest version, so that the computer is flashed to the latest version. I've done this before, and I just have to flash the computer to recover. If connecting iTunes doesn't work, you can try a few more times.

Forehead.. Seriously, the video game bus is really a rogue source. At the beginning, many friends installed their updates from Cydia after jailbreaking, and they became bricked directly.

If I'm not mistaken, your phone is in the same situation, stuck in the white apple stage. Don't panic first, see if the phone can be turned off, use the recovery mode, that is, home and power press and hold together for about 10 seconds, release the home button, keep holding power to try to enter recovery mode, and see if you can restore factory settings. If it still can't, it is recommended not to move and send it for repair.

A white apple is when the iPhone is turned on and the phone only displays a white Apple logo with a black background. The causes and solutions are as follows:

Files written to the system class are caused by problems such as the order of creation or installation, conflicts between software, and between software and systems. Connect your iPhone to your computer and put your iPhone into DFU mode.

The X w5566804 below is right. It seems that the landlord doesn't care about this problem anymore.

Hello, there are many reasons for "white apples", because the description is not very detailed, the reason for "white apples" may be that some pxl or deb software runs with system permissions, which will be modified to system files, so it leads to the appearance of white apples. That is, it is caused by conflicts between software and software, and between software and systems.

Workaround: An unjailbroken phone can only be solved by reflashing the firmware.

In the state of the white apple, plug in the data cable to connect to the computer, (at this time, keep iTunes in the boot state).

Press and hold the home button (that is the circle button) + the power button (that is, the power on and off button) at the same time.

All the way to the device screen black (i.e., when the device is turned off). Release the power button and wait for about 7-10 seconds until the iPhone prompts for recovery.

At this time, iTunes on your computer will also have a prompt of "Waiting to restore your iPhone".

Once you are sure, click Restore directly. At this time, basically the iPhone will help you restore the system by itself, and there will be prompts such as reboot in the middle, as long as you don't turn on the data cable, it will basically be successful.

I'm in the same condition as you, but I'm only 11 days old. Brain-dead Unicom asked me to go for testing, and then I went to the test they specified, saying that it would take 15 jobs to replace the new machine. I rely on, and I don't provide a backup machine, I rely on it, and I scold Y directly.

Later, Unicom couldn't solve it, so I went to the Sanlitun Apple store, explained the situation, took it directly for testing, and replaced it with a new machine after 1 hour. Despised Unicom's robber behavior, and told me when I bought it that the phone would not be returned or replaced if it had scratches and paint after opening. Grass, something.

Also praise Apple's after-sales and efficiency, and professional!

Then you can only re-flash the machine, and there is no other way to solve it, go to the next firmware.

Brush the machine yourself, or find after-sales to solve it.
