Huawei P9 Lite VNS-L31 Firmware Flash File (Stock ROM)

This guide covers how to install the official firmware on the Huawei P9 Lite VNS-L31. The phone shipped on Android 6.0 Marshmallow and was later updated to Android 7.0 Nougat, running on the HiSilicon Kirin 650 chipset. You can flash the firmware with the dload method or the Huawei Multi-Download Tool, and both are covered below.

What the stock ROM is for

The stock ROM is the operating system that comes preinstalled when you buy the phone. People usually leave it behind to run custom ROMs and other mods, but when something goes wrong during one of those changes, flashing the stock ROM back is the way to fix it. It can clear a boot loop, recover a bricked phone, and let you upgrade or downgrade the software.

Why flash stock firmware

• Unbrick the Huawei P9 Lite
• Fix a boot loop
• Upgrade or downgrade the software
• Unroot the phone
• Fix lag, stutter, and other bugs
• Fix performance, battery, or OTA update problems
• Return to stock to restore the warranty (where it still applies)

Upgrade using an OTG adapter or OTG cable with USB storage

1. Download the dload firmware from the link above, extract it, and copy it to a USB stick formatted as exFAT or NTFS.
2. Factory reset the phone from Settings (optional), then power it off.
3. Connect the USB stick to the phone with an OTG cable, with all the extracted dload files on it.
4. Press the Power button, and as the phone vibrates and shows the Huawei and Android logo, press the Power button three times to reboot into eRecovery mode.
5. Select Update Mode, then Memory card/OTG update mode. The update will start.

Those are the steps to flash the dload firmware using a USB stick. Here is how to do the same with an NM card.

Install dload firmware using a Huawei NM card

1. Extract the stock firmware and place the three extracted files on the Huawei NM card.
2. Factory reset the phone (optional), then power it off.
3. Press the Power button, and as it vibrates and shows the Huawei and Android logo, press the Power button three times to enter eRecovery mode.
4. Select Update mode, then Memory Card/OTG update mode. The update will start.

If you would rather update from the system itself, follow the next section.

Update from the system

1. Extract the dload firmware and move the three extracted files to the Huawei NM card or USB stick.
2. Open the dialer and enter *#*#2846579#*#*. From the menu that appears, select Software Update.
3. Select Memory Card Upgrade. The system reads the files from the SD card, USB storage, or NM card and flashes them.
4. When it finishes, you can safely remove the storage.

If those methods do not work, try one of the next two.

SD card update method

• Create a folder called dload on your microSD card.
• Extract the downloaded firmware ZIP on your PC, then copy the UPDATE.APP file into the dload folder on the microSD card.
