What should I do if the iphone baseband is broken?

Guided baseband is the communication system of iPhone, which is used to control mobile phone communication, telephone communication, WiFi wireless communication and Bluetooth communication. If the apple battery is not used for a long time, it will not be charged, and it needs to be activated to charge normally. Some batteries are activated and cannot be charged, indicating that the batteries have lost their functions of conducting electricity and storing electricity, and need to be replaced with good batteries.

The signal of iPhone is directly related to baseband. Under normal circumstances, when the firmware is upgraded, the baseband will be upgraded, and the baseband upgrade is irreversible. Therefore, the locked device should be careful when performing recovery, update, firmware leveling and other operations to avoid baseband unlocking after upgrading. What should I do if the iphone baseband is broken? Let's take a look at it next.

1. What is the iphone baseband?

Baseband is the communication system of iPhone, which is used to control mobile phone communication, telephone communication, WiFi wireless communication and Bluetooth communication. IPhone has related communication hardware and needs baseband communication system driver. With the working baseband, you can make phone calls, send and receive short messages and use 3G functions.

Except WIFI, of course. The baseband version can be found in the version number used by the modem in iphone settings → "About this machine". IOS and baseband are relatively independent and work together. After the baseband upgrade, many soft solutions will be invalid, and the locked version of iPhone will be useless. And worst of all, the baseband can hardly be degraded. Therefore, for the locked mobile phone, the baseband upgrade must be cautious, and it must be upgraded after being cracked. Of course, the lock-free version should also be cautious about baseband upgrade.

Second, what should I do if the iphone baseband is broken?

Touch screen damage is a common phenomenon of iphone, because the surface (92tO.Com) is tempered glass, which is brittle. If you accidentally fall to the ground, the screen will be damaged and cracked. Generally, the glass screen on the surface is broken, and the touch can still be used. It is because curved surface screen, commonly known as glass screen and touch screen, is composed of a glass screen and a touch screen, which are inseparable whole. Generally, the surface glass is broken outside, and the touch screen inside can be used normally without damage. Sometimes there is nothing wrong with the surface glass screen, but the touch screen inside is cracked, so the touch will fail.

After using the iphone for a long time, it occasionally crashes. Simply holding down the power button can't boot normally. This requires holding the on/off button for ten seconds at the same time. This will cause an Apple logo to appear on the screen, which should open normally after a while. Another situation is that due to software conflict or improper software operation, the screen always appears white apple or the icon showing the connection line +itunes, which always fails to boot, indicating that there is something wrong with the system and needs to be refreshed.

If the apple battery is not used for a long time, it will not be charged, and it needs to be activated to charge normally. Some batteries are activated and cannot be charged, indicating that the batteries have lost their functions of conducting electricity and storing electricity, and need to be replaced with good batteries. If the iPhone can't be charged or connected to the computer, the tail plug may be broken and need to be replaced with a new tail plug for testing.

Third, the iphone maintenance misunderstanding

1, the Home key is not protected.

Myth: Since the iPhone4 era, there have been many complaints that the iPhone's Home button is not durable, which leads everyone to use the iPhone in fear. They would rather turn on the "little white dot" than press the Home button several times.

Truth: The Home button before iPhone5 is really not durable, but it has been improved a lot a few years ago, and the English literal translation of "AssistiveTouch" is "Touch Button for Disabled People".

2, often use the flash as a flashlight, which is easy to burn out.

Myth: Flash is used to take pictures. If it is turned on frequently, it may burn out easily.

Truth: The flash next to the iPhone camera is actually an LED light, which usually lasts for tens of thousands of hours. As long as the phone is not turned on for a few hours, it will not cause any harm to the mobile phone.

3. The higher the pixel, the better the camera lens of the mobile phone.

Myth: iPhone 6 Plus has only 8 million pixels, and the camera lens is simply weak. Samsung S5 has16 million pixels, which is twice that of iPhone 6P. This is called hanging explosion.

Truth: Pixels only affect the size of a photo. The effect of a photo is good or bad. The biggest determinant is the photosensitive element. The more light each pixel can receive, the better the effect.

4. Using the power-saving App can effectively save electricity.

Myth: Various power-saving apps remind us that turning off xx applications can save xx% of power and make the battery of iPhone more durable.

Truth: The most power-saving App is to prompt us to turn off some unnecessary switches and shut down some background programs and processes that have not been used for a long time. Just double-click the Home button to end the background program.
