Can a 3G network phone be flashed into a 4G network phone?

1. Some mobile phones can be upgraded from 3G mobile phones to 4G mobile phones, while some mobile phones cannot. Brushing the system doesn't work either.

2. For example, the Apple 5 mobile phone is a 3G mobile phone, and it cannot be upgraded to a 4G mobile phone if you brush the system. But the Apple 5C can. However, when the signal is weak, it will automatically fall to the 3G network, and when the signal is strong, it will automatically connect to the 4G network. As shown in Fig.

1) Open the Apple 5c phone settings, there is only the 3G option in it.

3) When the signal is not good, it falls to the 3G network again.

Reasons why you can't brush:

The hardware of mobile phones and 4G mobile phones is different, and from 3G to 4G requires mobile phone hardware support.

The network baseband chips used in mobile phones and 4G mobile phones are different, resulting in different bands and codes, which cannot be brushed with each other.

Meaning of 3G mobile phone and 4G mobile phone:

3G mobile phone refers to the third generation of mobile phone, which integrates voice communication and multi-** communication, and can listen to songs, browse the web, and conduct meetings. Compared with the previous 2 generations of mobile phones, 3G mobile phones cannot be richer in functions and applications, and the Internet speed is much faster than that of 2G networks, and the experience is better.

4G mobile phone refers to the mobile phone of the 4th generation communication system, which is no different from 3G mobile phone in appearance, but supports 4G wireless transmission technology, which is much higher than the bandwidth of the cellular system of the 3G network in terms of communication bandwidth, and the network transmission speed is more than many times faster than the current wired broadband.

Difference Between 3G Phone and 4G Phone:

2.Coverage: 3G is wider than 4G networks, which can be reflected in remote or rural areas.

3.Network support: 4G phones support 2G 3G 4G network, and 3G phones support 2G 3G network.

4.Functional application: Compared with 3G mobile phones, 4G mobile phones can not only make calls and surf the Internet, but also have new ways to play entertainment and payment, and users can easily and safely swipe their mobile phones to consume.

No, because the mobile network baseband chip does not support the corresponding bands and encoding.

This involves the question of the principle of communication.

There are two reasons, 1: there is a problem with the flashing package, and 2: you have not turned on the 4G network in the settings.

For compatibility problems, it is recommended to use a flashing software with good compatibility for flashing--"Qitu".

There may be a problem with the flashing package, and it is recommended to re-flash the machine.

No, 4G mobile phones must need hardware support, and it is not possible to brush into a system that supports 4G, whether the mobile phone can be upgraded to 4G mainly depends on whether the mobile phone has a 4G module, and generally 3G mobile phones do not support 4G.

You can flash the machine with one click through the flashing wizard.

Flashing preconditions.

1.The phone has enough power, and it is recommended that more than 20% of the battery remains.

2.The remaining capacity of the phone's memory or external SD card is at least 100M larger than that of the ROM package.

Flashing process. 1.Open the Android version of the flashing wizard, and start the pre-flash detection after the app is launched to ensure that there will be no unpredictable problems after the phone is flashed.

2.After passing the test, select "Safe Flash" to start flashing (it is recommended to back up the data before flashing).

4.Once you've selected your ROM, you're ready to flash your computer.

5.After the flashing is complete, remember to restore the data that was backed up earlier.
