Sometimes, we find that the once invincible USB data cable suddenly fails, and the mobile phone and computer can't be connected. Don't worry, I'll give you some advice.

Little magic

First, do a little magic trick for the mobile phone: turn it on, press "2945#*#" quickly, then select "4" and "2", then turn it off and restart. Remember, don't choose "6", otherwise the information in the mobile phone will be lost. If it doesn't work, don't be discouraged.

Reinstall the USB driver

Next, unplug the data cable from the computer and reinstall the USB driver. Remember, you must unplug the data cable first, or you will be busy in vain. After installation, you should be able to reconnect in most cases. If it still doesn't work, we have another trick.

Add new hardware

Open my computer, enter the control panel, and then add new hardware. Follow the prompts and chooseNo. I want to choose new hardware from the list, and then choose the universal serial bus controller. After that, install from floppy disk and find the disk where your drive is located. Select the disk where your drive is located in the box below the drive, and then find the location of the USB driver in the big box above. Finally, confirm and complete the installation.
