Allview V4 Viper Pro
If your Allview V4 Viper Pro smartphone is running very slowly, hanging, you want to bypass the screen lock, or you have a full memory and want to erase everything, or you want to sell or give it away and want to ensure that nobody can access your files and passwords, you can do a factory reset to restore it to its original state like the first day.
In the following steps we explain how to format the Allview V4 Viper Pro to erase all your information and make it totally clean as it came out of the store.
Before doing a factory reset, we recommend deleting all the accounts on the device, specifically it is useful to unlink the Google account if you are going to sell, donate, or give away your V4 Viper Pro. This will avoid problems for the new user, as some newer devices include a functionality called FRP (Factory Reset Protection) that requires the same Google account or PIN code with which the Allview V4 Viper Pro was initially configured when factory resetting a device.
Keep in mind that a reset or return to the factory state on a mobile/cell phone deletes all its content, so make a backup of your data before doing it if you don't want to lose everything.
In case you do not want to erase the data from the device, you can try to restart the Allview V4 Viper Pro..
