Why does my Lenovo A790e phone keep doing this when I connect it to my computer?

Note: Your machine is a customized telecom machine, so you must install the "Tianyi Broadband" program, please understand.

Turn off the phone and try it, in one is whether there is anything wrong with the data cable.

You have to install Tianyi broadband first, in my computer, when you connect to the mobile phone, click on my computer, there is a Tianyi broadband there is a USB flash drive, you can connect after installation But first you have to open a pea, while constantly connecting, of course, you can't connect at this time, you have to install Tianyi broadband, and then you can absolutely line.

Isn't yours Lenovo A790E It's Telecom, right? Open my computer Install Tianyi Broadband After installation, try again? If it is useful, I hope to adopt it!! Mine is also Lenovo A790E This method definitely works, adopt it!!

Have you ever changed that data cable, if you have changed it, your phone's interface is good, it is you who said that the system problem of your mobile phone needs to be reinstalled. I just thought about it. This is the problem a lot of the time.

The common problem of this machine You re-insert and unplug the mobile phone card to try Mine is like this Every time you have to re-insert the card It's good I'm going to ask for telecom tomorrow.

Take a look at it in engineering mode, take a look at the network in the mobile phone information, switch the mobile network access point in the settings to cnnet, and it is impossible for a normal machine to be unable to access the network.

I didn't turn on mobile data.

Your Internet switch is not turned on.

The transmission connection is not open, or there is no wifi...

It depends on the strength of your signal.

To enter the correct password.

Turn off the router's on, wmm, short gi, and ap isolation.

My mobile phone has also encountered such a problem.,Can be charged,It's just not able to read the U disk.,My phone has a data cable.。。。 You first change the data cable,Second, you see if there is a problem with the plug.,If there's no problem.,Brush the system.。。。

You manually look at the application settings in the settings I don't know**Whether there is a check mark??? And then go into the development and put all the checkmarks... You're trying...

I guess it's your computer system problem!! Try switching to someone else's computer.

Dear to tell you, your data cable is broken, you can only charge and can't connect to data I have also had this situation.
