The phone can t connect to the data network after flashing, what s going on?

You first determine that the mobile phone is connected to the Internet (the mobile phone displays the data of the network connection up and down arrows), maybe the mobile phone is not connected to the Internet at that time because of the display Caton, etc., and then check the software settings of the network you use, restart the software to try, and finally restart the mobile phone, it is not possible to try other software can be networked No, if it is not good, it is basically determined that it is the firmware problem of the flash package, go to the forum where you flash the machine package to see if there is a reflection, and then see if there is a problem with others brushing the same package, others have no problem, Then re-brush or brush another bag.

Flashing package data needs to be double-cleared, as for what is called double-clear:

Turn it off completely, remove the battery and put it back on.

Press and hold the volume down + power button to power on, enter the recovery interface, and find the wipe data factory reset to erase user data and restore factory settings (an option that must be executed before flashing.

wipe cache partition to clear the system cache (executed before flashing) (you can also try this option if there is a problem with the system, it can usually be solved).

This is Shuangqing.

There is a problem with the network function in the flashing package.

After the parallel goods are flashed, an access point should be set up, and some software can also cause it.

All I know is that mine is missing a system software.

You can restart it and try it, if it doesn't work, go to the place where your phone is flashed and ask.

The specific operation method of mobile network data cannot be connected is as follows:

1.It may be because the data switch is not turned on, slide the phone notification bar to turn on mobile data.

<>3.Try a different SIM card or a different time period to troubleshoot network issues.

4.If it still doesn't work, you can back up the data on your phone first, and then restore your phone to factory settings.

5.If the problem persists, please bring the purchase invoice, repair card and machine to the mobile phone after-sales service center for inspection.

If the settings are normal, the mobile phone cannot connect to the data network, and the local network signal may be poor. Check whether the data settings of your phone are normal. Try it in a different place.

What a mobile phone, let's talk about the phone model!

It may be the reason for the baseband, which is caused by you not brushing the base!!

Wait a minute, it's like this after just flashing the machine.

Call the operator** to the manual service and ask him to refresh your network and ask for adoption.

There are two common possibilities for this problem, one is that there is a problem with the settings of the wireless router, and the type of encryption protocol that is turned on cannot be supported by your mobile phone, the most typical phenomenon in this situation is that the mobile phone can search for the network normally, and can also connect to the network through password verification normally, but either the IP address cannot be obtained, or the Internet cannot be accessed after obtaining the IP address. This can be adjusted on the wireless router by changing the protocol encryption method to "automatic" and restarting the wireless router once.

In addition, there is also a possibility that the MAC address filtering function in the "Security" function is turned on on the wireless router, resulting in the device with an unbound MAC address cannot access the Internet. (Not if you haven't turned it on.) ）

In that case, by the way, modify the channel mode of wireless networkless, if it is fixed, you can try to change it to "automatic", in addition, clear the cached network on the phone, and then reconnect.

The signal, or the wifi software is not brushed well,,, caused by an interruption in the middle of flashing.

According to your description, if your phone cannot connect to the Wi-Fi network, we recommend that you do the following:1Turn on the wireless signal of the wireless router and make sure that the router network function is normal, and the router connection password is at least 8 digits.

2.Connect the router with another device to see if it is normal. 3.

If you can connect before, but now the connection fails, it is recommended to forget the network and reconnect, operation: Settings - WLAN settings - click and hold the name of the network to be deleted - forget to delete the network. 4.

Restart your phone and router separately. 5.Check and confirm whether the router settings are correct according to the router manual or contact the router customer service.

6.An attempt was made to replace the static IP address. 7.

Try it with a different wireless router.

The wifi module fails, it may be a problem in the flashing package, it is recommended that you find a new package and re-flash it.
