What should I do if the Huawei 4C fails to flash and can t turn on?

The mountains, the faint light in the house rests entirely on this.

What you're talking about should be the English version of the recovery interface.,In this interface, the power button is confirmed.,The volume plus and minus keys are up and down keys respectively.。

The flashing steps under this interface are as follows, and the corresponding English is followed by a remark.

Enter Recovery (use the power off key + volume + -, depending on the model, the premise is to flash recovery), back up your phone's important data;

wipe data factory reset;

Wipe cache partition;

Select Install Zip from SDCARD;

Wait for the flashing to complete, and then select Reboot System Now.

Software problem collection] sincerely answer for you, satisfied, if you have any questions, please ask even.

1. The battery is dead. It is recommended to plug in the mobile phone charger and try again after 5 minutes.

3. Caused by flashing, it is what we usually call the bricking of the mobile phone. At this time, it is necessary to go to the after-sales service to redo the mobile phone system.

1. The boot cord is not normal and the boot is not turned on. Under normal circumstances, when pressing the power button, the trigger terminal voltage of the power button should change significantly, if there is no change, it is generally due to poor contact of the power button or the power line is broken, the component is soldered, and damaged. When repairing, use an external power supply to supply power, observe the change of the ammeter, if the ammeter does not respond, it is generally a disconnection of the power line or a bad power button.

2. The battery power supply circuit is not turned on due to poor operation. During maintenance, the power supply can be provided by different power supply methods in order to distinguish the fault range and determine whether the electronic switch is normal. Generally speaking, if the power supply circuit is bad, pressing the power button ammeter will not respond, which is very similar to the bad power line.

3. The power supply IC is not turned on due to abnormal operation. For the mobile phone to work normally, the power supply circuit should output a normal voltage to supply the load circuit. When the power supply is normal and the power supply is normal, it means that the power supply IC is soldered or damaged.

If it is judged that the power supply IC is soldered or damaged, it needs to be replanted and replaced, which requires high operation skills and needs to be honed in practice.

Fourth, the software is not normal caused by the failure to boot. 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.

5. Do not turn on the machine due to other reasons. There are many reasons why the mobile phone does not turn on, such as the poor LCD screen, the short circuit of the components (especially the power amplifier), etc., which may cause the mobile phone not to turn on, and there are some models that must use the real-time clock as the chip clock signal and sleep clock signal. If the real-time clock is not normal, it may also cause the phone to not turn on.
