If the iPhone has just entered the water, do not click any button after it enters the water, because it is easy to burn the motherboard after activating the button. At that time, do not focus on anything, and stand up directly. When the water drips up, take the activated carbon bag to the place where the phone leaves the water. After several hours of water being sucked up by the activated carbon bag, take it to the place where the temperature is higher,Click the button after the internal moisture is completely dry. This is not a problem. I'm afraid it will take a long time to blow the phone with an electric blower when using the activated carbon bag.
In fact, no matter whether it is used normally or not, there is still water inside our mobile phones, which will not be easily sucked up by rice.Even if the normal display is used now, the mobile phone is working with a disease, which may crash or even be scrapped at any time. Because the water enters the circuit of the motherboard, if you do not disassemble the machine and use the board washing water and ultrasonic wave to do an internal cleaning, it will slowly oxidize and rust. After a certain period of time, if one of the many circuits is short circuited, the whole motherboard will be abandoned, and it is the kind that cannot be repaired.Because by that time, all the lines were almost rusty.
If the screen is black after water ingress, the machine cannot be started. Most of them are the power supply of the motherboard or the baseband of the CPU hard disk.This is the water that has entered the main board. The main science popularization concept is that the main board is a structure composed of many small chips, including baseband, cpu, hard disk, wifi module, touch screen ic, and so on. Because many of the parts inside are metal structures, water ingress is very easy to oxidize and rust. If some of them are short circuited, the whole main board is likely to fail to work. Generally speaking, the main board is burned.
Because the chip level maintenance technology is relatively difficult in the industry, I have been doing Apple maintenance technology here in Guangzhou. I have seen many maintenance masters in small places, who told others directly and generally that if the motherboard burned, it would be necessary to replace it.
The price of a whole motherboard is almost equal to the price of most mobile phones, so it is necessary to find a factory store that can carry out chip level.Because it is likely that only one power supply IC is broken. It only costs 200 or 300 yuan to replace a power supply IC.
Your smart phone has no hardware to restore factory settings, only the default settings, but it's useless. The software you installed can't be deleted. You have to enter the settings to delete it, and nothing happens when you install the fingerprint lock screen?Should press the main menu, it will light up. Here you press and hold the fingerprint displayed on the screen, it will flash. Generally, it will flash 5 times by default to unlock. This is not really fingerprint recognition. After flashing 5 times, let go, and it will open. If you can't press the main menu again, you can set it several times in the software after unlocking. Remember, let it flash several times next time and let it go.
One button brushing process of Qitu machine: 1. First turn on the Qitu Brush Machine, and then turn on the USB debugging mode after connecting the mobile phone. When the Qitu Brush Machine detects that a model is connected, it will automatically install a driver for the model. After the driver is successfully installed, it will automatically connect the mobile phone. During this period, the mobile phone should be kept in the normal startup state. 2. Click [One click to flash] to select the ROM package you want to flash. If you have not downloaded the flash ROM package, you can download it in the Qitu flash ROM market.After selecting the flash ROM package of the mobile phone, enter the data backup interface, and the flash opportunity will clear the contacts, SMS, call records and applications. It is recommended that you backup and restore after the flash. 3. After the data is backed up, the machine will start to run. 4. After the operation is completed, the phone will enter the auto refresh mode. At this time, just wait patiently for the phone to restart automatically.
