How to upgrade the Huawei G520 mobile phone system

Of course, you can use the computer to flash the phone, and the mobile phone can also be flashed.

Niu Erye solves the system upgrade problem for users who can't upgrade the Huawei G520 system:

You can do it 100% according to my operation, and now the Unicom version of the system is B196. As follows:

1. Log in to the Huawei terminal network.

Wait for the official upgrade package to click on the system update in the settings. Or go and flash it yourself.

See if this model has an upgrade package, if there is one, it can be upgraded, otherwise it can't.

There is a detailed introduction on the official website of Huawei mobile phones.

Three methods: The premise of the upgrade is that the phone is not rooted or has been rooted but must be unrooted, otherwise the upgrade may fail.

The first way is to upgrade with the phone's built-in upgrade software** under the network connected to WiFi, because the traffic is too large, and your traffic will be finished if you use a 3G signal. The method of entry is "Settings" "About Phone" "System Update" "**Upgrade". The next step is for the phone to automatically upgrade the system.

The second way is to use an SD card to upgrade. First of all, find the firmware package of huaweig520-0000 from Huawei's official **technical support,Then**down,(Huawei's official website is www huawei com,Open it"Technical support"Individual consumer"Under "software**",Click on it,You will enter**page,Enter g520-0000 in the software search bar on this page,You can find its latest firmware package。 And then ** down).

After the DLOAD is decompressed to the SD card, you can use the phone's built-in upgrade program to select "Upgrade from SD card" to upgrade. ("Settings" "About phone" "System update" "SD card upgrade").

The third method is that if the phone fails to upgrade due to some unknown factors and cannot boot the system normally, you can force the upgrade from the SD card, and the SD card root directory must have a dload folder containing the firmware package. The method is to press and hold the volume up and down and power buttons at the same time in the shutdown state to enter the forced upgrade.

After the upgrade is completed, you can re-use software such as Root Master for rooting. Hope!!
