iPhone appears computer and data cable logo?

1. First of all, you need to connect your phone to the computer, open iTunes, and [iTunes to detect an iPhone in recovery mode] will be displayed

2. If iTunes has no response after connecting the phone, keep the data cable connected to the computer, and then follow the following methods.

Press and hold the lock screen key until the Apple logo appears on the screen

3. Then continue to press and hold the lock screen button, and then press and hold the home button at the same time4. Wait until the screen turns black, release the lock screen button, and continue to press and hold the home button, then iTunes will detect the iPhone in recovery mode

6. If the network is not very good and iTunes is slow, you can go to the Internet in advance to **iPhone firmware, because Apple has not allowed to brush the lower version of the firmware, so be sure to ** the latest firmware, and pay attention to whether it is consistent with your iPhone model.

7. Next, wait for the iPhone to be restored, which can be completed in more than ten minutes.

When the data cable is connected to the computer, it will automatically pop up and turn it off.

The appearance of a computer and a data cable on the Apple phone means that the firmware system of the mobile phone has been damaged.

If the screen shows that the computer and a data trapped cable appear, it means that the firmware system of the mobile phone has been damaged, the mobile phone has not been able to boot normally, and the iTunes software connected to the computer needs to restore the system before it can be turned on.

The Apple mobile phone appeared with a computer and a data cable to solve the problem as follows:

2. After iTunes successfully recognizes the iPhone, the iTunes software will automatically pop up a prompt message to remind the user that the current iPhone is in the system recovery state and needs to be restored.

4. After the iTunes software automatically restores the system to the iPhone, the phone will automatically restart, and it can be used normally after restarting.

5. Since the iTunes software will erase all the original data on the phone, including account information, etc., after the phone is restarted, the user needs to use AppleID again to activate the phone.

Showing a data cable is to indicate that the user needs to be charged, and the power is used up, so the Apple mobile phone is turned off.

If you can't turn on the device after charging, the reasons and solutions are as follows:

1. The logic circuit is not normal and does not turn on.

The logic circuit focuses on detecting the chip selection signal CE and license signal OE of the CPU to each memory, these signals are very important, but the key is to look for these signals, because more and more mobile phone logic circuits use BGA packaged integrated circuits, it is very difficult to find these signals. If possible, it is best to refer to the drawings to find these signals and their measurement points. The chip selection signal is a pulse signal that jumps up and down, if the memory CE is not available, it means that the CPU is not working, repair soldering, re-soldering, replace the CPU or carefully check whether the conditions for CPU work are met.

If there is no chip selection signal for a memory, it is usually because the memory is damaged. If the CE signal is present, the CPU-F is working properly, and the fault may be a software failure or a bus failure or a memory failure.

Mobile phones often cause deformation of the board in use, such as pressing buttons, falling, touching and other external forces will cause some chips to be desoldered, and generally repairing or resoldering these chips will solve most of the problems. When the normal chips cannot be turned on by soldering or substitution, and the reading and writing cannot be passed by using the disassembly-free maintenance instrument, the peripheral circuits should be measured one by one and these chips replaced.

2. The software is not normal and the computer is not booted.

In the process of turning on the mobile phone, if the software can not be passed, it will not be turned on, the software error is mainly due to the abnormal memory data, when the line is not obviously disconnected, you can replace the normal chip, version or rewrite the software, some of the circuit in the chip will be damaged, and it can not be passed when rewritten. When rewriting the software, the original data should be saved for emergency repair.

Flashing the machine with AISI assistant After the flashing is completed, it can be used normally.

1.First of all, you need to connect your phone to the computer, open iTunes, and [iTunes will be displayed to detect that one is recovering.。。

2.If iTunes doesn't respond after connecting your phone, keep the cable connected to your computer, and then press and hold the lock screen button as follows.

3.Then go ahead and press and hold the lock screen button, and then press and hold the home button.

4.Wait until the screen goes black, release the lock screen button, and continue to press and hold the home button, at which point iTunes will detect the recovery mode.

The iPhone shows a computer with a data cable that the phone is stuck in recovery mode, which is also one of the most common system failures of iOS devices.

When users encounter upgrading iOS system, but accidentally stuck in recovery mode, iPhone won't boot normally. Due to the inconsistency of the iPhone upgrade stage, the method that can be successfully solved is also inconsistent. So try a force restart to see if you can get out.

Or connect your cable first. Open iTunes. When using iTunes Recovery, the device will be erased, and all data needs to be backed up in advance.

Common faults and solutions for Apple mobile phones:

1. There is no response when the device is turned on.

When encountering an iphone automatic shutdown, no matter how you press the power button there is no response, in this case, you can use the number of Tong Cong Fan cable iphone to connect to the computer, it can be automatically started. You can also keep the power button and home button for a few seconds at the same time, and there is a chance that a white Apple logo will appear.

2. The iPhone screen is unresponsive.

Sometimes I was playing with my phone, and suddenly the screen of my iPhone lost its response, and I couldn't move forward and couldn't return. At this time, you can try to press the home button and the power button at the same time to force the shutdown until a white apple appears on the screen. In addition, this method can also clear some basic caches, if you often use your iPhone to watch**or watch**, you can try this method occasionally.

3. Occasionally, there is a problem of automatic hanging up when playing **.

Generally speaking, there is a problem with the light sensing line. When dialing**, cover the opening at the top of the iPhone screen with your hand, and if the screen is not off, replace the light cable. In addition, the hands-free microphone, light sensor, proximity sensor, and front-facing camera are all on the same line, and any one of them will need to be replaced.

4. The voice is muffled when playing **.

There is a problem with the handset net. Usually, most of the problems with the handset are due to the handset net.

5. There are bright spots on the iPhone screen.

Press and hold the highlight to see if there is a color change around it, and if it is, it may be because a screw has fallen off under the screen. If there is no color change, you will need to replace the screen backlight plate, and if the problem has not been solved, you will need to replace the entire screen. <>
