There are a few reasons why you may need to factory reset your Huawei P9 device. Perhaps your phone has glitches and this is the last resort or you may be planning on selling it.

Whatever the reason, performing a factory reset is easy. Take a look below for the different options available.
Method 1 – Master Reset via Device Buttons
This first method may be the easiest way to perform a factory reset. However, your device buttons need to be responsive in order to use this method.
In addition, this is a good option to use if you’re experiencing screen freezes or your screen is otherwise unresponsive.
Step 1 – Power Off Device
First you need to make sure that your device is turned off. Press and hold the Power button until your phone turns off completely.
Step 2 – Access the Recovery Menu
To initiate a factory reset from the power off position, press and hold both the Volume Up and Power buttons at the same time.
Hold the buttons until you see the Huawei logo on your screen. Once you see the logo, you can release the buttons.
Step 3 – Factory Reset Your Phone
When you see the recovery menu options pop up on your screen, use your Volume buttons to scroll down to the “Wipe data/factory reset” option. Confirm your selection by pressing the Power button.
Repeat the actions above by selecting Factory Reset and confirming with the Power button. Your phone will ask you to confirm “Reboot system now”. Accept this option by using the Power button.
Method 2 – Master Reset via the Settings Menu
This is a good option to use if your phone menus are still responsive. However, if your phone screen is frozen, you may want to try the smartphone button reset method instead.
Step 1 – Start from an Off Position
First, make sure your phone is shut down completely. To do this, hold down the Power button for a few seconds.
Step 2 – Access the Settings Menu
Next, turn your phone on again. From the Home screen, choose the Settings icon. Scroll down through your menu options until you find Advanced Settings. Select this option.
Step 3 – Factory Reset Your Device
From the Advanced Settings menu, choose Backup & Reset. On your next menu, scroll down and select “Factory Data Reset” from the options.
This is the point of no return, so if you haven’t backed up your phone data, you should do so before continuing on.
After that, scroll down again and tap on Reset Phone. Confirm your action by tapping on Reset Phone again and your Huawei P9 will perform a factory reset.
Final Thought
Performing a factory or master reset on your Huawei P9 is simple, but remember to backup your data somewhere before you do it. This type of reset erases all data, files, and settings from your device and once they are gone, they are unrecoverable.
Thankfully, Huawei provides native backup features on your device. So if you decide to use their backup methods, restoring or recovering your phone is just as simple.
