The baseband of the mobile phone is damaged or the mobile phone cannot receive the signal, and it is impossible to access the Internet or make a call. Damage to the baseband will affect your normal use. If this happens, it is recommended to bring the relevant products to the after-sales service center for brushing.

Prompt to shut down because of the baseband problem, it is equivalent to no card occasionally this problem may be a problem with the baseband chip, or the system baseband file may be damaged.

Brush can not solve, that is the problem of the chip.

The iPhone's signal is directly related to the baseband. Normally, the firmware is upgraded, the baseband will be upgraded, and the baseband upgrade is irreversible. Therefore, the lock device should be cautious when performing recovery, update, and flat firmware operations, so that the baseband cannot be unlocked after the upgrade. So what if the iphone baseband is broken? Let's take a look at it next.

1. The baseband is the communication system of the iPhone. It is used to control the communication of mobile phones, control telephone communication, WiFi wireless communication, and Bluetooth communication. The iPhone has related communication hardware, which needs to be driven by the baseband communication system. With the normal working baseband, you can make calls, send and receive text messages, and use 3G functions.

2, of course, except for WIFI. The baseband version can be queried from the version number used by the modem in the iPhone → "About this machine". iOS and baseband are relatively independent and work together. After the baseband upgrade, many soft solutions will be invalid, and a locked version of the iPhone will not be available. The most serious is that the baseband can hardly be downgraded. Therefore, for a mobile phone with a locked version, the baseband upgrade must be cautious, and must be upgraded after waiting for the crack. Of course, the lock-free version should also be treated with caution.

3, touch screen damage is a common phenomenon of iphone, because the surface is made of tempered glass material, it is relatively brittle, a little accidentally fell to the ground, it will lead to cracks in the screen. Generally, the surface glass screen is broken, and the touch can still be used. It is because the surface of the screen, commonly known as the glass screen, touch screen, is composed of a layer of glass screen and a touch screen, the two of which are undividable as a whole, the external damage is generally the surface of the glass, the inside of the touch screen No damage, the touch can be used normally, sometimes there is no problem with the surface glass screen, and there is a crack in the touch screen, then the touch will fail.

4, the iphone used for a long time after the occasional crash situation, simply press and hold the power button is not able to boot normally, it is necessary to simultaneously press the switch machine to press the home button for ten seconds, this is a screen will appear Apple logo, you should be able to boot normally after a while. Another situation is that due to software conflicts or improper operation of the software, the white apple or the display cable +itunes icon has been displayed on the screen, and the machine has been unable to open, indicating that the system has problems and needs to be re-brushed.

5, if the Apple battery is not used for a long time, there will be no charge, you need to activate the battery to charge properly. Some batteries are activated and there is no way to charge the battery, indicating that the battery has lost its ability to conduct electricity and store electricity. A good battery needs to be replaced. If the iPhone can't be charged and you can't connect to the computer, it's possible that the tail plug is broken and you need to replace it with a new one.

6, Home button does not protect the misunderstanding: From the iPhone4 era, there have been many complaints about the iPhone's Home button is not durable, resulting in everyone using the iPhone is fearful, preferring to open the "Little White Point" do not dare to press the Home button a few times. The truth: The Home button before the iPhone 5 does not exist, but it has improved a lot since a few years ago, and the small "AssisTIveTouch" is literally translated as "touch button designed for disabled people". 2, often flash the flashlight is easy to burn out the wrong zone: the flash is used for photography, often open when the flashlight is used may be easy to burn. Truth: The flash next to the iPhone camera is actually an LED light. The life span is usually tens of thousands of hours. As long as it is not continuously open for a few hours, it will not cause any harm to the mobile phone. 3, the higher the pixel, the better the camera lens is wrong: iPhone 6 Plus is only 8 million pixels, the camera lens is simply weak, the Samsung S5 16 million pixels, twice the iPhone 6P, this is called hanging fried days. Truth: Pixels only affect the size of the photo taken. The effect of a photo is good or bad. The biggest factor is the photosensitive element. The more light per unit pixel, the better the effect. 4, the use of power-saving app can effectively save power misunderstanding: a variety of power-saving App reminds us to turn off the xx application can save xx% of the power, feeling that the iPhone's battery is more durable. Truth: The Power Saver app prompts us to close some unnecessary switches and close some background programs and processes that are not used for a long time. Just double-click the Home button to end the background program.

100-300 does not wait. Some basebands can be brushed back and some brushes will not come back. According to the version. The baseband is the iPhone's communication system, which is used to control the communication of mobile phones, control telephone communication, WiFi wireless communication, and Bluetooth communication. The iPhone has related communication hardware, which needs to be driven by the baseband communication system. With the normal working baseband, you can make calls, send and receive text messages, and use 3G functions.

The baseband is a small, very special stand-alone computer system running inside the iPhone. It runs separately from the main system that controls the iPhone software (email, google maps), and it communicates with the main system of the iPhone through the internal network. The price is 50 yuan.

Heavy Duty Connector

Heavy Duty Connectors (HDC) provide extensive industrial inserts,

alternate or direct-current connectors for heavy-duty industrial applications; multi-pole connectors for use in electronic machinery, robots, electric panels, control equipment, power and control- or signal-circuit connectivity; enclosures for standard, harsh and EMC environments; plastic and metal cable glands. All products are designed with top-quality materials.

The principal HDC parts are comprised of die-cast aluminum alloy with either a polyester powder (nickel-plated for EMC versions) finish or a self-extinguishing thermoplastic. Coupling stability and accidental opening protection is achieved by two locking systems (mono-block levers in galvanized or stainless steel or springs and pegs in stainless steel). Sealing of dust, water and aggressive agents is assured with internal protective gaskets.
