How to solve the black screen after flashing the Huawei phone

Hello landlord, there is a prerequisite, the black screen is caused by software. If it is caused by hardware failure, please find Huawei's after-sales service center! There is no solution to the hardware failure here.

Check the battery level. Sometimes the screen goes black after flashing because the phone is out of battery, and the reason is as simple as that. So please make sure that the battery of your phone is sufficient before flashing, and it is best to keep it above 60%.

If the power is too low, there will be a black screen when you brush the phone to play, and the phone must be black when the phone is out of battery.

Software issues. Are you sure you clear the data when flashing? If you don't clear your data, your phone may not boot due to compatibility issues.

At this time, we need to press and hold the power button for more than 10 seconds to force the phone to restart, as long as the phone can enter the standby interface, we can repair it through the normal upgrade recovery operation.

If there is no response to the long press, you need to recover by forcing the upgrade.

Let's take out the SD card in the mobile phone first, and then go to the corresponding software upgrade package on the official website. Put the best software upgrade package into the dload folder in the SD card, if you don't have this folder, you need to create one yourself. Then insert the SD card into the phone, press and hold the up and down keys of the volume button, and press and hold the power button for more than 10 seconds.

At this time, the Huawei phone will enter the forced upgrade summary of the SD card. Of course, please make sure that the battery of the mobile phone is sufficient before upgrading, and do not fail to upgrade due to insufficient battery.

After the mobile phone enters the upgrade, the entire upgrade process will be automatically completed, and the upgrade time can be completed in about 5-10 minutes.

Let's start with a new flash. Initiators cannot be deleted.

Taking Huawei P50 and the system as an example, the reasons and solutions for the black screen of Huawei mobile phones are as follows:

1. The battery of the mobile phone is insufficient: check whether the power of the mobile phone is electric (check the charging interface by plugging in the charging interface), the power is less than 2%, which will lead to an automatic black screen, and the mobile phone needs to be charged at this time.

2. Software problem guide with high-end automatic black screen: to confirm whether the black screen problem occurs after installing a certain software, you can uninstall the software and view it, or you can restore the factory settings and upgrade the mold ruler to the latest software version.

3. System failure: There may be a black screen problem if there is an error in the mobile phone system itself, and the mobile phone can be forced to restart. Press and hold the power button for more than 10 seconds to force restart the phone, and if the phone can enter the standby interface normally, the phone will be repaired through the normal upgrade and recovery operation.

If it still won't turn on or restart, you need to repair your phone by forcing an upgrade to resume operations.

If the black screen of your phone persists, you can contact Huawei's official customer service.

Mobile phones can be said to have become a must-have daily necessities for most of us, if there is a problem with the mobile phone at any moment, I believe many people will not be able to stand it, and the black screen of the mobile phone is one of the most common problems, so why does your mobile phone have a black screen? Is there a solution?

If the phone screen is black, in this case, it is first recommended that the landlord check whether the phone is still charged? It may be that the phone is out of battery, causing the phone to turn off automatically, in this case, the black screen should not be able to turn on, even if it is turned on, it is estimated that the black screen will be black immediately, because the battery power is not enough to support the operation of the mobile phone system, in this case, as long as the charger is connected, charge the mobile phone for a while, and then as long as the battery is charged, it should be able to light up the mobile phone screen if it can be turned on.

If the mobile phone is out of power and has a black screen, then charging the mobile phone in this case can be solved, but if the landlord is still unable to solve the problem or the battery power display is normal during the charging process, in this case, you can basically rule out the cause of the lack of power and cracking, because if the mobile phone is in use suddenly black screen, it is not excluded that the mobile phone card causes the mobile phone black screen. Although there is no response to operating the phone, the phone system is still running, and in this case, a forced restart of the phone should be solved. As long as you can enter the system normally after restarting, you can solve the problem by lighting up the phone screen.

However, if the landlord is sure that the mobile phone is not dead, and the mobile phone screen cannot be lit, in this case, it cannot be ruled out that there may be other hardware problems with the mobile phone. In this case, it is recommended to go to the after-sales service to test the hardware of the mobile phone.

This could be a faulty phone battery circuit or motherboard. If the mobile phone falls into the water, take timely measures to prevent further losses.

1. Drop into clean water when the power is on, this situation generally does not need to be disassembled.

1 Power off as soon as possible.

2 Shake it dry, but don't shake the machine off, the idea is to shake the water out of the wide orange screen. If there are water droplets left on the screen, it will be round and comic after drying.

3 Place under a slight heat source such as a desk lamp or spotlight to let the moisture slowly dissipate. This process takes more than six hours. Do not use a strong heat source such as a hair dryer in a hurry.

After these three steps of processing, the power supply can basically work normally.

2. Drop into non-corrosive liquid in the case of power failure. In this case, it can be assumed that the machine is not damaged. But maybe the LCD screen will be more ugly.

1 Shake dry vigorously, but don't shake the machine off.

2 If there is no trace on the LCD screen, treat it according to Article 3 of the first point.

3 If there is something left on the screen and it is very serious, do not deal with it according to point 1, paragraph 3, because although the electronic circuit can work normally, the screen may be quite ugly. It can be sent to the nearest maintenance department for processing or dismantling the machine for cleaning by yourself.
