OV丨What is the problem that the mobile phone update software has been installed, but it can t be tur

It is recommended that you forcibly shut down and restart the phone, if the interface is still like this after the shutdown and restart, it is recommended that you re-channel in other applications**channel**, and install this application to try it, if it still doesn't work, it is recommended that you check the internal storage space of the phone, if the storage space is insufficient, this problem may also occur, clean up the storage space, if the storage space is relatively sufficient, it may be caused by a system failure, it is recommended that you restore the phone to factory settings once, Any problems caused by system failures can often be solved by restoring factory settings.

2.If other third-party software can be used normally, only this software may not have compatibility problems with the mobile phone system.

3.If the software cannot be installed normally due to insufficient memory on the phone, it is recommended that you move the multi** files stored in the phone to the external SD card to expand the memory space of the phone and reinstall it;

5.Update the system version of the phone and try to install it.

6.Back up your phone's data (book, SMS, multiple files, etc.) and restore factory settings.

7.If the problem persists, send the phone to the nearest service center for testing and further treatment.

Secondly: When installing the software, it prompts that the application D sequence is not installed or that there is an error when parsing the package, which is usually the possible cause

2. There is a problem with the electronic signature of the application installation package, which means that the installer has been tampered with.

Dear users, hello:

1. The boot line is abnormal: use an external power supply to supply power to the mobile phone, use the electric meter to detect whether the indication has changed, if there is no change, it is likely that the boot line is broken or the boot button is not in good contact.

2. The power supply circuit of the battery is abnormal: use the external interface to supply power to the mobile phone, see if it returns to normal when it is turned on, if it is normal, it is determined that the power supply circuit of the mobile phone is abnormal.

3. The IC of the mobile phone power supply is abnormal: test the test point of the outer cavity circuit of the power supply IC according to the circuit schematic diagram to see whether the test value is normal.

4. The system clock and reset of the mobile phone are abnormal: you can use the dual total oscilloscope to detect the CPU power supply of the mobile phone to check whether the waveform in the reset is correct.

5. Problems with logic circuits: that is, faults in the circuit version of mobile phones, which can generally be solved by repair welding.

6. Software conflict: The installed software does not match the system of the mobile phone, which may also cause the mobile phone to fail to boot, you can connect the mobile phone to the computer to delete the program.

7. If it is a copycat mobile phone, then I estimate that I can't turn on the machine because the chip inside is burned, or some of the small parts inside are loose, but this situation will only appear if you drop it, the chip burns may be because you charge it for too long, and the chip is burned, if the battery is charged, it is these aspects, if it is a brand-name mobile phone, such as Nokia, Motorola. These situations are rare, unless it is artificial, if it is a brand-name smartphone, and it is not used improperly, it is a software problem, it may be a system crash, or because of the mobile phone poisoning caused by software damage, generally this can only go to the maintenance office, however, I think the biggest possibility is caused by static electricity, it is recommended that you do not open the blind repair yourself, or go to the repair office to carry a good model!
